Can You Train Your Bladder Into Bad Habits?

Bladder training and pelvic floor rehabilitation

Bladder training and pelvic floor muscle training are often recommended for urinary urgency and leakage. They address different parts of bladder control, though, and the right approach depends on the symptoms and on whether the pelvic floor muscles are weak, overactive, or both.

A pelvic floor that works well needs to be able to contract when support is needed and relax when it is time to pass urine or stool. More squeezing is not always better.

What is bladder training?

Bladder training is a structured way of gradually changing toileting habits and responding to urgency. It aims to reduce “just in case” trips, increase the time between voids when appropriate, and help a person regain confidence that an urge can settle without immediately rushing to the toilet.

It is a supported behavioural treatment. It does not mean ignoring pain, forcing yourself to hold on for a long time, or following a rigid schedule regardless of what your body is telling you.

A bladder diary for a few days can help record fluid intake, urination times and volumes, urgency, leakage and night-time waking. Together with a clinician, a person can use this information to choose a realistic starting interval. The interval can then be extended gradually, often by small steps, while using calm breathing and urge-control strategies. Adequate fluid intake, avoiding excessive caffeine, and addressing constipation may also help. Fluid restriction should not be used without advice, as too little fluid can cause dehydration and concentrated urine.

When may bladder training help?

Bladder training is commonly offered as an initial treatment for people with:

  • Overactive bladder (OAB) symptoms: urgency, with or without urgency leakage, usually accompanied by increased daytime frequency and/or waking at night to urinate, when infection or another obvious cause has not been found.
  • Urinary frequency or urgency: including frequent “just in case” voiding or difficulty delaying a trip to the toilet.
  • Mixed urinary incontinence: a combination of leakage with urgency and leakage with activities such as coughing or exercise. Bladder training can be combined with pelvic floor muscle training.
  • Urgency without leakage: urgency can still be bothersome and may respond to behavioural strategies.

The International Continence Society defines OAB as a symptom syndrome. It is not the same thing as a urodynamic finding called detrusor overactivity. Some people with OAB symptoms show involuntary bladder contractions during urodynamics; others do not. Urodynamics is not needed for every person with typical OAB symptoms. Overactive Bladder

What does “sensory overactive bladder” mean?

“Sensory urgency” or “sensory OAB” is sometimes used when a person feels an early or unusually strong need to pass urine, often at relatively small bladder volumes, but testing does not show involuntary detrusor contractions. The term is used inconsistently and is not a separate diagnosis in the current ICS symptom definition.

When infection, pain-related bladder conditions, obstruction, significant residual urine and other relevant causes have been considered, a person with urgency or increased bladder sensation may still be offered bladder training according to their symptoms and goals. A normal urodynamic study does not mean that the symptoms are imagined, and a finding of detrusor overactivity does not by itself determine which treatment is best.

Practical urge-control strategies

When an urge arrives before the planned time:

  1. Pause and stop moving if it is safe to do so. Sit or stand comfortably.
  2. Breathe slowly and allow the abdomen and pelvic floor to soften.
  3. Avoid rushing, which can increase the sense of urgency.
  4. If you can contract and fully release the pelvic floor comfortably, a few brief, gentle contractions may help suppress the urge. Then let the muscles go completely.
  5. When the urgency has eased, walk calmly to the toilet if you still need to go.

The approach should be adjusted if contractions cause pain, increase urgency, or make it harder to empty. Repeatedly delaying urination despite pain, a very full bladder, or difficulty passing urine is not the aim.

Pelvic floor muscle training for stress urinary incontinence

Stress urinary incontinence (SUI) is leakage with coughing, sneezing, laughing, lifting or exercise. It commonly occurs when the urethral closure mechanism and its support do not respond adequately to a rise in abdominal pressure.

For SUI, pelvic floor muscle training (PFMT) aims to improve the muscles’ strength, endurance, timing and coordination. Guidelines recommend a supervised programme for at least three months as an initial treatment for women with SUI or mixed incontinence. Training is also commonly used in men recovering from prostate surgery, with advice tailored to their operation and recovery. NICE

A correct contraction should feel like a gentle closing and lifting around the openings of the pelvic floor. It should not feel like pushing down, holding your breath, or tightening the buttocks and thighs instead. Each contraction needs a complete release afterwards. A pelvic health physiotherapist or clinician can check that the muscles are being used correctly and can tailor the programme to the person.

For leakage with a cough or lift, a physiotherapist may teach a brief pelvic floor contraction just before and during the effort. This is sometimes called “the knack.” It is a coordination strategy, not a substitute for a progressive strengthening programme.

PFMT can also support urgency control when a person can contract and relax the muscles correctly. It may be combined with bladder training for OAB or mixed symptoms. However, a high number of forceful contractions is not suitable for everyone.

When pelvic floor relaxation may be the priority

Some people have pelvic floor muscles that are persistently tense, tender, difficult to coordinate, or unable to relax fully during urination or bowel movements. This may be described as a high-tone, overactive or non-relaxing pelvic floor. Symptoms can include pelvic pain or pressure, difficulty starting the stream, straining, a stop-start stream, a feeling of incomplete emptying, constipation, pain with sexual activity, or urinary urgency and frequency. These symptoms have other possible causes as well, so assessment matters.

When examination suggests that the pelvic floor is overactive or does not relax appropriately, treatment may focus first on down-training and coordination, often with a pelvic health physiotherapist. This can include relaxed diaphragmatic breathing, awareness of pelvic floor release, comfortable toileting posture, avoiding straining, and addressing constipation or pain. Biofeedback may be used in selected cases. The aim is not to push or bear down forcefully, but to learn a comfortable release.

In this situation, repeatedly doing “Kegels” without assessment may aggravate pain, urgency or difficulty emptying for some people. The evidence for relaxation-based treatment is less extensive than the evidence supporting supervised strengthening for SUI, but guidelines support relaxation-focused pelvic floor therapy for selected functional emptying problems. Uroweb

Relaxation is not the opposite treatment for ordinary stress incontinence. If the main problem is leakage with exertion and the pelvic floor is weak or poorly coordinated, strengthening and timing are usually the relevant goals. If a person has both stress leakage and a tight, painful or poorly relaxing pelvic floor, a clinician or physiotherapist can sequence the treatment: first restore comfortable release and coordination where needed, then progress to strengthening without reinforcing excessive tension.

When to seek assessment

A clinician may review the symptom pattern, medications, fluid and caffeine intake, bowel habits, urine test, bladder diary, pelvic floor function and how well the bladder empties. Further tests are considered when the diagnosis is uncertain or when results could change management.

Seek medical advice rather than relying on bladder training alone if you have visible blood in the urine, painful urination or fever, new difficulty passing urine, a persistent weak stream, recurrent infections, significant pelvic pain, new neurological symptoms, or a sudden change in bladder control. These symptoms can have causes that need specific assessment.

Key points

  • Bladder training is a first-line behavioural option for urgency, frequency, OAB symptoms and many cases of mixed incontinence.
  • “Sensory OAB” is an imprecise term; urgency can be real and treatable even when urodynamics does not show detrusor overactivity.
  • Supervised pelvic floor muscle training is a first-line treatment for SUI, but correct contraction and full relaxation matter.
  • A tight or non-relaxing pelvic floor may need relaxation and coordination work before strengthening.
  • The best programme is based on an assessment, not on the assumption that every pelvic floor needs more squeezing.

Your Bladder and Your Bowels: The Connection Nobody Talks About

/0 Comments/in /by

The bowel–bladder connection: how good bowel habits can support bladder health

When urinary urgency or leakage is troubling you, bowel habits may be the last thing on your mind. Yet the bowel and bladder share the limited space of the pelvis, the pelvic floor muscles and parts of their nerve supply. Constipation can contribute to urinary symptoms in some people, so bowel health is often worth discussing during a bladder assessment.

This does not mean that constipation explains every bladder problem. Infection, prostate or pelvic floor conditions, medication effects, neurological conditions and other causes may need to be considered too.

How can constipation affect the bladder?

A full rectum can press on the bladder and change the space available for it to fill. In some people this may increase urinary urgency or frequency, contribute to urgency leakage, or make it harder to empty the bladder comfortably. Constipation and bladder symptoms may also occur together because of shared pelvic floor or neurological problems.

The relationship is not the same for everyone, and constipation is only one possible contributor. Bladder symptoms should be assessed on their own merits, especially if they are new, persistent or worsening.

Some medicines used for bladder symptoms, including anticholinergic medicines, can make constipation worse. Pain medicines, iron and some other medicines can also affect bowel habits. If you think a medicine may be contributing, discuss it with your doctor or pharmacist rather than stopping it yourself.

The pelvic floor connection

The pelvic floor is a group of muscles and connective tissues that supports the bladder, bowel and other pelvic organs. It helps maintain urinary and bowel control, and it must also relax and coordinate when you empty your bladder or bowel.

Repeated straining to pass hard stool can place ongoing pressure on the pelvic floor. A pelvic floor that is weak, painful, tense or poorly coordinated may affect both bladder and bowel emptying or control. Treatment therefore depends on what the muscles are doing: strengthening is useful for some forms of leakage, while people who cannot relax or coordinate the pelvic floor may need a different approach, sometimes with a pelvic health physiotherapist.

How are the bladder and bowel nerves connected?

The bladder and rectum have different jobs, but their nerve pathways meet and interact through the spinal cord, pelvic nerve networks and the brain. The pathways below are a simplified guide; the actual nerve networks are interconnected.

Nerve pathway Main spinal levels Role in bladder and bowel function
Pelvic splanchnic nerves (parasympathetic) S2–S4 Help the bladder contract to empty and contribute to rectal activity and bowel emptying. They also carry important sensation from the lower urinary tract and rectum.
Hypogastric nerves (sympathetic) About T11–L2 Support bladder storage by relaxing the bladder wall and helping maintain outlet closure. They also contribute to bowel storage and internal anal sphincter function.
Pudendal nerves (somatic) S2–S4 Provide voluntary control of the external urethral sphincter, external anal sphincter and parts of the pelvic floor. These muscles help maintain continence and must coordinate with relaxation during emptying.

Bladder filling and emptying, bowel filling and defecation are coordinated with pelvic floor activity and brain control. Because some of these pathways and muscles are shared, neurological conditions or injuries affecting the brain, spinal cord or sacral nerves can affect both bladder and bowel function. A full rectum can also alter the local pressure and sensory environment around the bladder.

Constipation is not only about how often you go

Bowel frequency varies. Not having a bowel motion every day does not, by itself, mean you are constipated. It is also important to mention:

  • hard or lumpy stools;
  • needing to strain or push repeatedly;
  • discomfort or pain when passing stool;
  • a feeling that the bowel has not emptied completely; or
  • needing to use your fingers or change position to help stool pass.

A short bowel diary, used alongside a bladder diary, can help identify whether urinary urgency or leakage changes when constipation is worse.

Good bowel habits to support pelvic health

A few practical habits may help maintain regular, comfortable bowel movements:

  1. Respond to the urge. Try not to repeatedly postpone a bowel motion. Many people find it helpful to allow unhurried time after a meal, when the bowel may be more active.
  2. Use a comfortable position. Sit with your feet supported on a small footstool so your knees are a little higher than your hips. Lean forward with your forearms on your thighs and keep your abdomen relaxed.
  3. Avoid prolonged straining. Breathe out gently rather than holding your breath and pushing hard. If stool will not pass, get up and try again later instead of sitting and straining for a long time.
  4. Eat a varied, fibre-containing diet. Whole grains, vegetables, fruit, legumes, nuts and seeds can help. Increase fibre gradually to reduce bloating. Adults’ fibre needs vary; one commonly used guide is around 22–34 grams a day, adjusted for age, health and tolerance.
  5. Drink an appropriate amount. Adequate fluid helps fibre work and can soften stool. Your needs vary, and people who have been advised to restrict fluids because of heart, kidney or other conditions should follow their treating clinician’s advice. Restricting fluids to manage urinary frequency may worsen constipation.
  6. Keep moving regularly. Walking and other suitable physical activity can support bowel function.
  7. Review medicines and ongoing symptoms. Ask your doctor or pharmacist whether medicines may be contributing. Persistent constipation may need tailored treatment; a clinician can advise whether dietary changes, a laxative or pelvic floor assessment is appropriate.

If you have difficulty relaxing the pelvic floor or feel that stool is blocked despite soft stools, simply adding more fibre or doing repeated pelvic floor squeezes may not solve the problem. Ask about an assessment of bowel emptying and pelvic floor coordination.

Looking beyond the bladder

Improving bowel habits may reduce one contributor to bladder symptoms, but it is not a substitute for investigating persistent urinary problems. A clinician may ask about both bladder and bowel symptoms, review medications, test the urine and check how well the bladder empties. Further assessment depends on the symptoms and medical history.

Seek medical advice for ongoing or worsening urgency, leakage, difficulty passing urine or constipation. Blood in the urine or stool, severe abdominal pain, vomiting, inability to pass urine, or a sudden major change in bowel or bladder control needs prompt medical attention.

Urethral bulking for stress urinary incontinence: a first procedure or an option after a sling?

/0 Comments/in , , /by

Leaking urine when you cough, laugh, exercise or lift something is called stress urinary incontinence (SUI). It differs from urgency incontinence, when a sudden need to pass urine leads to leakage. Some women have both. Identifying which symptom is most troublesome matters because an injection aimed at SUI will not reliably treat urgency.

Urethral bulking involves placing small deposits of material into the wall of the urethra, usually through a fine instrument passed into the urethra. The deposits help the urethra close when pressure rises. You may hear this described as periurethral bulking, although many contemporary injections are delivered through the urethra into its surrounding wall. This is generally a day procedure under local anaesthesia or sedation/general anaesthesia, depending on the circumstances. It does not place a sling or mesh tape.

Could bulking be my first procedure?

Yes. After a trial of pelvic floor muscle training and discussion of other conservative measures, bulking can be chosen as a first procedure for appropriately assessed SUI. It may appeal to someone seeking a shorter procedure and recovery, or wishing to avoid a sling. It is also an option when a larger operation or anaesthetic carries additional risk. It is not usually the first treatment before conservative care. USANZ’s 2026 position statement lists bulking alongside autologous fascial slings, colposuspension and synthetic midurethral slings among the standard options that should be discussed. UGSA’s patient information stresses its lower success and frequent need for repeat treatment. [1–3]

Bulking, synthetic midurethral sling surgery, a sling made from the patient’s own fascia, and colposuspension have different benefits and risks. A donated-tissue (allograft) sling is distinct from a sling made from your own tissue (autograft) and from a synthetic mesh sling; the strength and duration of evidence for each are different. No single procedure is best for every woman. [1,4]

How effective and durable is it?

The realistic aim is often less leakage, rather than guaranteed dryness. Success figures change substantially depending on whether researchers count complete dryness, improvement, satisfaction, or avoidance of further treatment. UGSA’s patient leaflet quotes about 40–50% cure or improvement and reports that approximately 30% need a further injection within two years. These are broad counselling figures, not a prediction for an individual. [2]

Some women remain improved for years, but repeat injections or another operation may be needed. In a randomised comparison of polyacrylamide hydrogel injection and synthetic tension-free vaginal tape for primary SUI, the tape achieved better objective continence at one year (negative cough test 95.0% versus 66.4%). The five-year follow-up did not establish that injection was non-inferior to tape. The EAU similarly advises that bulking is generally less effective than slings or colposuspension for cure, and that repeat injection is likely. These findings do not mean everyone should have a tape: the value of a less invasive procedure and the acceptability of a possible repeat treatment are personal considerations. [4–6]

What if I still leak after a sling?

Bulking can be considered for persistent leakage soon after a sling or recurrent leakage after an initial period of improvement. It can sometimes reduce leakage without placing another sling. A 2022 systematic review of 11 studies after synthetic midurethral sling failure reported a pooled 75% cure-or-improvement rate, but also pooled failure and further-operation rates of 32% and 25%. The studies differed considerably in their patients, products, follow-up and definitions of success; the 75% figure should not be presented as a personal chance of cure. An American Urogynecologic Society clinical practice statement also recognises bulking as an option after a sling. [7,8]

After an allograft sling, the same clinical possibility exists, but the published post-sling bulking evidence is mainly about synthetic midurethral slings. We should not simply transfer those success figures to donated-tissue slings. The precise graft, previous surgery and examination findings should guide an individual discussion.

An injection should not be used to mask a sling complication. Before offering more treatment, I would review the original operation, check urine and bladder emptying, examine for prolapse, scarring and vaginal exposure, and assess whether leakage occurs with coughing or with urgency. Cystoscopy, a bladder diary, pad testing or urodynamics may be appropriate, especially after previous surgery, mixed symptoms, pain, blood in the urine or difficulty emptying. A tape or graft causing obstruction, exposure, erosion, infection or pain may require its own assessment and treatment. [1,3,7]

Is it safe? What are the side effects?

Most reported problems are short lived, but no injection is risk free. Possible effects include:

  • burning when passing urine and a little blood in the urine;
  • urinary tract infection;
  • temporary difficulty emptying the bladder, occasionally requiring short-term catheterisation;
  • new or persisting urgency symptoms; and
  • incomplete benefit, recurrence or the need for another injection or operation.

Less commonly, there may be persistent pain, a collection or infection at the injection site, or a reaction or complication related to the particular material. Risks also depend on anaesthesia, previous surgery and the chosen product. Emptying should be checked before discharge. Seek prompt assessment if you cannot pass urine, develop fever, worsening pain or heavy bleeding. [2,4,8]

Choosing a treatment

The first step is to confirm the type and severity of leakage and clarify your goals: complete dryness, meaningful improvement, shorter recovery, avoiding mesh, or avoiding the likelihood of repeat treatment. Pelvic floor therapy remains an initial option. When a procedure is appropriate, we can compare bulking with sling and colposuspension procedures using your examination findings, health history and preferences. If you have already had a sling, the reason for the continuing leakage deserves a fresh assessment before choosing another procedure.

This page is general education, not a recommendation for a particular product or a promise of a result. Treatment, including its material, risks, costs and alternatives, should be discussed during an individual consultation.

Urodynamic Studies: Understanding How Your Bladder Works

/0 Comments/in , /by

Bladder problems are not always as straightforward as they appear.

Two people may both complain of urinary urgency, leakage or difficulty emptying their bladder, yet the underlying causes can be completely different. One bladder may be contracting when it should be relaxing, another may not contract strongly enough, and sometimes the bladder is behaving perfectly well while the outlet is causing all the trouble.

This is where urodynamic studies, often simply called urodynamics, can help.

Think of urodynamics as a stress test for the bladder. Rather than simply looking at its anatomy, we observe how the bladder fills, stores urine and empties while simultaneously measuring pressures, urine flow and sometimes pelvic floor activity.

The aim is not merely to produce a collection of colourful graphs. The important question is:

What is the bladder actually doing, and will knowing this change the treatment?

What Are Urodynamic Studies?

Urodynamics refers to a group of tests that assess the function of the bladder, urethra and urinary sphincter.

Depending on the clinical situation, testing may evaluate:

  • How much urine the bladder can comfortably hold
  • Bladder sensation during filling
  • Whether the bladder remains relaxed while filling
  • Whether involuntary bladder contractions occur
  • Whether urinary leakage occurs and why
  • The pressure required to store urine
  • The strength of the bladder muscle during urination
  • Whether there is obstruction to urinary flow
  • Whether the bladder empties completely
  • How the urinary sphincter and pelvic floor behave during filling and voiding

Urodynamics therefore investigates function rather than simply structure.

An ultrasound or cystoscopy may show us what the urinary tract looks like. Urodynamics tells us what it is doing.

Who May Need Urodynamic Testing?

Not every patient with urinary symptoms requires urodynamics.

For many straightforward urinary problems, the diagnosis can be made from the history, examination, bladder diary, urine testing, flow studies and ultrasound.

Urodynamics becomes particularly useful when the diagnosis is uncertain, symptoms are complex, previous treatments have failed, neurological disease is present, or an invasive treatment is being considered where understanding bladder function may alter the choice of treatment.

Common indications include:

Urinary Incontinence

Urodynamics may be useful when assessing:

  • Stress urinary incontinence
  • Urgency urinary incontinence
  • Mixed urinary incontinence
  • Persistent leakage following previous continence surgery
  • Incontinence following prostate surgery
  • Complex or unexplained urinary leakage

In straightforward female stress urinary incontinence, urodynamics is not necessarily required before treatment. It becomes more useful when symptoms and clinical findings do not agree or when there are complicating factors.

Overactive Bladder

Patients with overactive bladder may experience:

  • Urinary urgency
  • Frequent urination
  • Nocturia
  • Urgency urinary incontinence

Urodynamics can sometimes demonstrate detrusor overactivity, where the bladder muscle contracts involuntarily during filling.

Importantly, a normal urodynamic study does not necessarily exclude overactive bladder. Symptoms and urodynamic findings do not always travel together.

Difficulty Emptying the Bladder

Patients may report:

  • Poor urinary flow
  • Hesitancy
  • Straining
  • Intermittent flow
  • Incomplete emptying
  • Urinary retention

The challenge is determining why.

Is there an obstruction?

Or is the bladder muscle simply not contracting strongly enough?

The symptoms can look remarkably similar, but the treatments can be very different.

Men With Lower Urinary Tract Symptoms

In men with prostate enlargement, urodynamics may help distinguish between:

Bladder outlet obstruction

and

Detrusor underactivity, where the bladder muscle has insufficient strength to empty effectively.

This distinction may be particularly valuable before prostate surgery when there is uncertainty about whether removing the obstruction will improve urinary flow.

Neurological Bladder Dysfunction

Urodynamics has an especially important role in patients with neurological conditions such as:

  • Spinal cord injury
  • Multiple sclerosis
  • Parkinson’s disease
  • Spina bifida
  • Stroke
  • Certain spinal disorders

In these patients, we are interested not only in urinary symptoms but also in whether bladder pressures could potentially damage the kidneys.

Before or After Certain Urinary Procedures

Urodynamics may also be considered:

  • Before complex continence surgery
  • Following unsuccessful continence surgery
  • Before some bladder outlet procedures
  • Following prostate surgery when symptoms persist
  • When considering treatments such as bladder Botox or sacral neuromodulation in selected complex patients

What Happens During a Urodynamic Study?

The test is usually performed as an outpatient procedure.

It generally takes approximately 30–60 minutes, although this varies depending on the type of study being performed.

You can usually eat, drink and take your normal medications unless specifically instructed otherwise.

Step 1: Arriving With a Comfortably Full Bladder

You may be asked to arrive with a reasonably full bladder.

You will urinate into a special toilet called a uroflowmeter.

This measures:

  • Urine volume
  • Maximum urinary flow rate
  • Average flow rate
  • The shape of the urinary flow curve
  • How long urination takes

An ultrasound may then measure how much urine remains in the bladder.

This is called the post-void residual.

Step 2: Placement of Small Catheters

A very fine catheter is gently passed through the urethra into the bladder.

A second small pressure catheter is usually placed into the rectum, or occasionally the vagina.

Why two pressure measurements?

Because pressure inside the abdomen affects pressure inside the bladder.

By measuring both, the computer can calculate the pressure generated specifically by the bladder muscle:

Detrusor pressure = bladder pressure − abdominal pressure

This simple equation sits at the heart of conventional urodynamics.

Step 3: Filling the Bladder

The bladder is slowly filled with sterile fluid.

During filling, you will be asked to describe what you feel.

We may record:

  • First sensation of bladder filling
  • First desire to urinate
  • Strong desire to urinate
  • Maximum bladder capacity

The pressure inside the bladder is continuously monitored.

Normal filling cystometrogram. During filling, the bladder accommodates increasing volume while detrusor pressure (Pdet) remains relatively stable. Coughs cause corresponding rises in Pves and Pabd without a true detrusor contraction. Sensations such as first sensation, first desire and strong desire can be marked on the tracing.

 

Step 4: Provocative Testing

You may be asked to:

  • Cough
  • Strain
  • Stand
  • Change position
  • Listen to running water

These manoeuvres are not designed to make the test unnecessarily theatrical. They help reproduce the circumstances under which your symptoms normally occur.

If urinary leakage occurs during coughing without an involuntary bladder contraction, this may demonstrate urodynamic stress incontinence.

Step 5: Voiding

Once the bladder is comfortably full, you will be asked to urinate.

During urination we simultaneously measure:

  • Urinary flow
  • Bladder pressure
  • Abdominal pressure
  • Detrusor pressure

This is called a pressure-flow study.

It can be extremely useful when determining whether poor urinary flow is caused by obstruction or weak bladder contraction.

What Does Urodynamics Measure?

Bladder Sensation

We assess when you first become aware that the bladder is filling and when the desire to urinate becomes stronger.

Sensation may be:

  • Normal
  • Increased
  • Reduced
  • Absent

Abnormal bladder sensation may occur in several neurological and functional bladder disorders.

Bladder Capacity

The amount of urine the bladder can comfortably hold is measured.

A small functional capacity may occur with conditions such as severe urgency or bladder hypersensitivity, although capacity must always be interpreted in clinical context.

Bladder Compliance

A healthy bladder should behave rather like a flexible reservoir.

As it fills, its volume should increase without a major rise in pressure.

Poor bladder compliance means pressure rises excessively as the bladder fills.

This is particularly important in some neurological bladder disorders because persistently elevated storage pressures can potentially threaten the upper urinary tract.

Detrusor Overactivity

If the bladder muscle contracts involuntarily during filling, this is called:

Detrusor overactivity.

It may be associated with:

  • Urgency
  • Urgency incontinence
  • Frequency
  • Nocturia

When associated with an underlying neurological condition, it may be described as neurogenic detrusor overactivity.

Detrusor overactivity. During bladder filling there is an involuntary increase in Pdet that cannot be explained by a corresponding increase in abdominal pressure. The contraction may be associated with urgency and, when leakage occurs, urgency urinary incontinence.

Stress Urinary Incontinence

If urine leaks when coughing or straining without a detrusor contraction, this supports a diagnosis of:

Urodynamic stress incontinence.

Additional measurements such as leak-point pressures may occasionally contribute to assessment in selected patients.

Bladder Outlet Obstruction

During urination, a pattern of:

High bladder pressure + low urinary flow

may suggest obstruction.

In men, benign prostate enlargement is a common cause.

Other causes include:

  • Urethral stricture
  • Bladder neck obstruction
  • Previous continence surgery
  • Dysfunctional voiding

Bladder outlet obstruction: pressure-flow study

https://images.openai.com/static-rsc-4/Efx8v2pSLdy0yriNx_qrcdTAHacUkb8mu_Sb7IjS9JvC0wxMQnPCPhcGQqAt0MQUNQ5jvnXe4yfU0qsIfsNRYrR7VLV4HhGFH6Ko01-kkE8GfSflqXD25Q6gkF3bmxyKYN9iYNHRqCJ0bV-igYyNfPP-21Nuvrls3kleV1a2fqsUDDQTALKE8mVkjEwglUbr?purpose=fullsize

Bladder outlet obstruction. During voiding the bladder generates a relatively high detrusor pressure, but urinary flow remains reduced. This high-pressure, low-flow relationship is characteristic of increased bladder outlet resistance.

In men, pressure-flow studies allow calculation of the Bladder Outlet Obstruction Index (BOOI):

BOOI = PdetQmax − 2(Qmax)

For men, BOOI >40 is generally classified as obstructed, 20–40 as equivocal and <20 as unobstructed.

Detrusor Underactivity

Sometimes the urinary flow is poor because the bladder muscle does not generate sufficient pressure.

This is known as:

Detrusor underactivity.

This distinction matters.

Operating on the prostate of a patient whose main problem is a very weak bladder may not produce the expected improvement in urinary flow.

Urodynamics can therefore occasionally prevent us from treating the wrong end of the plumbing.

Dysfunctional Voiding

Some patients involuntarily contract their pelvic floor or urinary sphincter while attempting to urinate.

Instead of the outlet opening smoothly, it intermittently closes.

Pelvic floor electromyography may help identify this pattern in selected patients.

Understanding the Urodynamic Tracing

A urodynamic report typically contains several pressure and flow curves.

At first glance, the tracing can resemble an enthusiastic seismograph.

The important measurements usually include:

Pves: pressure measured inside the bladder.

Pabd: pressure measured within the abdomen.

Pdet: pressure generated by the bladder muscle.

Flow: the rate at which urine leaves the bladder.

The relationship between these measurements allows us to understand what is happening during bladder filling and emptying.

Common Findings and What They May Mean for Treatment

Urodynamic Finding Possible Interpretation Potential Treatment Direction
Normal storage and emptying Normal urodynamic study Treatment guided by symptoms and other investigations
Detrusor overactivity Overactive bladder physiology Bladder training, medication, Botox, neuromodulation
Stress leakage Stress urinary incontinence Pelvic floor therapy, bulking agents, sling or other continence surgery
High pressure + low flow Bladder outlet obstruction Treatment of obstruction where appropriate
Low pressure + low flow Detrusor underactivity Emptying strategies, intermittent catheterisation or selected treatments
Poor compliance High-pressure storage Pressure-reducing treatment and upper urinary tract surveillance
Pelvic floor activation during voiding Dysfunctional voiding Pelvic floor physiotherapy/biofeedback
Significant residual urine Incomplete bladder emptying Identify obstruction versus impaired bladder contraction

The urodynamic result is not a treatment plan by itself.

It must be interpreted alongside symptoms, examination findings, bladder diaries, ultrasound, cystoscopy and other investigations where appropriate.

How Urodynamics Can Guide Treatment

If Detrusor Overactivity Is Found

Initial treatment may include:

  • Bladder training
  • Fluid modification
  • Pelvic floor physiotherapy
  • Antimuscarinic medication
  • Beta-3 agonist medication

For persistent symptoms, options may include:

  • Intravesical Botox injections
  • Sacral neuromodulation
  • Other specialist treatments in selected patients

If Stress Incontinence Is Demonstrated

Treatment depends on severity, sex, previous surgery and individual circumstances.

Options may include:

  • Pelvic floor rehabilitation
  • Continence devices
  • Peri-urethral bulking agents
  • Sling procedures
  • Colposuspension in selected women
  • Male sling following prostate surgery
  • Artificial urinary sphincter in appropriate men

If Bladder Outlet Obstruction Is Demonstrated

Treatment depends on the underlying cause.

For benign prostate enlargement, options may include:

  • Medication
  • Minimally invasive prostate treatments
  • Laser prostate surgery
  • Transurethral prostate surgery
  • Other surgical procedures appropriate to prostate size and anatomy

A urethral stricture or bladder neck obstruction requires a different treatment strategy.

If the Bladder Muscle Is Weak

Treatment may involve:

  • Double voiding
  • Timed voiding
  • Reviewing medications
  • Treating reversible causes
  • Intermittent self-catheterisation when necessary
  • Long-term catheterisation in selected circumstances
  • Sacral neuromodulation in carefully selected patients with non-obstructive urinary retention

The key issue is avoiding unnecessary outlet surgery when obstruction is not actually the problem.

If Bladder Storage Pressures Are High

This is particularly important in neurological bladder disease.

Treatment may include:

  • Medication
  • Intermittent catheterisation
  • Intravesical Botox
  • Regular renal imaging
  • Monitoring kidney function
  • Repeat urodynamic assessment
  • Reconstructive bladder surgery in uncommon severe cases

Here the objective extends beyond improving symptoms. We may also be trying to protect kidney function over the long term.

Are Urodynamic Studies Uncomfortable?

Most patients tolerate the investigation well.

Passing the small catheter can cause brief discomfort, and there may be some mild burning when urinating afterwards.

Having an audience while your bladder performs under laboratory conditions is admittedly not anyone’s preferred afternoon entertainment, but the clinical staff performing these studies do this routinely and will make the process as private and comfortable as possible.

Possible Side Effects and Complications

Urodynamic testing is generally safe.

Possible side effects include:

  • Temporary burning during urination
  • Urinary urgency
  • Minor urethral discomfort
  • A small amount of blood in the urine
  • Urinary tract infection
  • Temporary difficulty urinating

Significant complications are uncommon.

Patients should seek medical advice if they develop fever, chills, worsening urinary symptoms, significant bleeding or an inability to urinate following the test.

Does Everyone With Bladder Symptoms Need Urodynamics?

No.

This is an important point.

Urodynamics should generally be performed when the result is likely to answer a clinically relevant question or potentially alter management.

The investigation is particularly valuable when:

  • Symptoms are complex
  • The diagnosis remains uncertain
  • Symptoms and examination findings disagree
  • Previous treatment has failed
  • Neurological bladder dysfunction is suspected
  • There is significant urinary retention
  • Complex surgery is being considered
  • Understanding bladder pressure or contractility could change treatment

Testing simply because “we haven’t done one yet” is not a particularly compelling indication.

Urodynamics: Turning Symptoms Into Physiology

Patients often arrive describing urgency, leakage, poor flow or difficulty emptying their bladder.

These symptoms tell us what is happening.

Urodynamics can sometimes tell us why.

By measuring how the bladder stores and releases urine, we can distinguish between problems involving the bladder muscle, urinary sphincter, pelvic floor and bladder outlet.

Most importantly, urodynamics can help ensure that treatment is directed at the underlying problem rather than simply the symptom.

The Bottom Line

Urodynamics is not necessary for every bladder problem. But when the diagnosis is uncertain or treatment decisions depend on understanding bladder function, it can provide exceptionally useful information.

A good urodynamic study does more than generate graphs.

It helps answer the question that matters most:

What treatment is most likely to work for this particular bladder?

This information is intended for general patient education and does not replace individual medical assessment. The need for urodynamic testing and interpretation of results should be discussed with your treating urologist or continence specialist.

Pelvic Floor Rehabilitation Before and After Prostate Surgery

/0 Comments/in , /by

Preparing the Pelvic Floor for Recovery

Urinary leakage is one of the most common concerns men have when preparing for prostate surgery, particularly radical prostatectomy for prostate cancer. Fortunately, urinary control usually improves progressively after surgery, and pelvic floor rehabilitation can play an important role in helping men regain continence.

Pelvic floor rehabilitation is more than simply “doing Kegels”. It involves learning which muscles to use, how to contract them correctly, when to relax them, and how to incorporate them into everyday activities.

Importantly, more exercise is not necessarily better. The aim is a pelvic floor that is strong, coordinated and responsive, rather than one that is constantly clenched.

What Is the Male Pelvic Floor?

The pelvic floor is a group of muscles forming a supportive sling beneath the pelvis. These muscles contribute to:

  • urinary continence;
  • bowel control;
  • support of the pelvic organs;
  • sexual function; and
  • control of pressure generated during coughing, lifting and physical activity.

After radical prostatectomy, the anatomy of the urinary continence mechanism changes. The prostate and prostatic urethra are removed and the bladder is reconnected to the remaining urethra. Urinary control consequently becomes more dependent upon the remaining urinary sphincter and its supporting pelvic floor musculature.

This is why pelvic floor rehabilitation is particularly relevant after prostate cancer surgery.

Why Start Pelvic Floor Rehabilitation Before Surgery?

Ideally, pelvic floor rehabilitation begins before the operation.

The principal advantage of pre-operative training is not necessarily building dramatically stronger muscles. Rather, it gives the patient an opportunity to identify and correctly activate the pelvic floor before surgery, when there is no catheter, discomfort or postoperative urinary leakage.

Evidence regarding whether pre-operative pelvic floor muscle training independently improves long-term continence rates is mixed. Current European guidelines conclude that pre-operative training has not consistently demonstrated an additional long-term benefit. However, pelvic floor muscle training after radical prostatectomy may shorten the time taken to recover continence.

For many patients, a consultation with a physiotherapist experienced in men’s pelvic health before surgery is therefore useful.

Finding the Correct Pelvic Floor Muscles

A pelvic floor contraction should feel as though you are trying to:

stop yourself passing wind while simultaneously shortening or drawing the penis slightly inward and lifting the scrotum.

The movement should be subtle.

During the contraction:

  • continue breathing normally;
  • avoid holding your breath;
  • keep the abdomen relatively relaxed;
  • avoid strongly squeezing the buttocks;
  • avoid excessive tightening of the thighs; and
  • completely relax the pelvic floor between contractions.

Some men find the correct muscles immediately. Others inadvertently brace their abdominal, buttock or thigh muscles.

This is one reason why an assessment by a pelvic floor physiotherapist can be valuable.

Should I stop my urine flow to find the muscles?

Stopping the urinary stream once can sometimes help identify the muscles involved, but repeatedly practising pelvic floor exercises by interrupting urination is generally not recommended.

Regularly stopping and starting the stream can interfere with normal bladder emptying.

A Practical Pelvic Floor Exercise Programme

There is no single exercise prescription that is perfect for every man. Pelvic floor strength, endurance, coordination and postoperative continence vary considerably.

A physiotherapist may therefore modify the programme according to your examination and progress.

A typical programme contains several components.

1. Slow contractions: strength and endurance

Gently contract and lift the pelvic floor.

Hold the contraction for approximately:

5–10 seconds

Then relax completely for approximately:

5–10 seconds

Repeat approximately:

8–10 times

The quality of the contraction is more important than achieving a particular number.

If you can only maintain a good contraction for three seconds initially, three good seconds are preferable to ten seconds of straining.

2. Quick contractions

The urinary sphincter also needs to react rapidly.

Contract the pelvic floor firmly for approximately one second, then completely release it.

Repeat:

5–10 times

These faster contractions help train the pelvic floor to respond to sudden increases in abdominal pressure.

3. The “Knack”

One of the most useful techniques is learning to contract the pelvic floor immediately before an activity that normally produces leakage.

For example, gently activate the pelvic floor just before:

  • coughing;
  • sneezing;
  • standing from a chair;
  • bending;
  • lifting;
  • getting out of a car; or
  • performing physical exercise.

This anticipatory contraction is sometimes called the Knack.

It turns pelvic floor training from an isolated exercise into a functional skill.

How Often Should I Exercise?

This is where the principle of quality rather than quantity becomes important.

For many men, a structured programme performed two to three times per day is sufficient during active rehabilitation.

A session might consist of:

8–10 controlled slow contractions followed by 5–10 quick contractions.

However, this should not be regarded as a universal prescription. Your physiotherapist or surgeon may recommend a different programme according to your muscle strength, continence and ability to relax the pelvic floor.

The pelvic floor is skeletal muscle. Like other muscles, it needs work, recovery and progression.

Doing hundreds of contractions every day is rarely necessary.

Can You Do Too Many Pelvic Floor Exercises?

Yes.

One of the common misconceptions after prostate surgery is:

“If ten exercises are good, one hundred must be better.”

Unfortunately, pelvic floor muscles can become fatigued just like any other muscle.

Excessive training or constantly holding the pelvic floor contracted can potentially cause:

  • pelvic or perineal discomfort;
  • difficulty relaxing the pelvic floor;
  • urinary urgency;
  • difficulty starting urination;
  • interrupted urinary flow;
  • a sensation of incomplete bladder emptying;
  • pelvic muscle fatigue; and
  • occasionally worsening leakage later in the day as the muscles tire.

A healthy pelvic floor needs to be able to contract strongly and relax completely.

Continence does not require walking around all day with the pelvic floor permanently switched on.

How Do I Know When I Am Doing Enough?

Your programme is probably adequate when you can:

  • identify the pelvic floor reliably;
  • contract it without excessive abdominal or buttock activity;
  • maintain several controlled contractions without losing strength;
  • completely relax between contractions;
  • activate the muscles quickly before coughing or lifting; and
  • progressively incorporate pelvic floor control into normal activities.

Progress after prostatectomy is often better measured by continence rather than the number of exercises performed.

Useful measures include:

  • number of pads used each day;
  • degree of pad wetness;
  • a 24-hour pad-weight test;
  • leakage during walking or exercise;
  • ability to remain dry overnight;
  • ability to reach the toilet without leakage; and
  • changes over several weeks rather than from one day to the next.

When Should Exercises Restart After Surgery?

Follow the instructions given by your surgeon.

Pelvic floor contractions are usually stopped while the urinary catheter is in place.

Training can generally recommence after catheter removal once your surgical team considers it appropriate. European guidance notes that pelvic floor muscle training is commonly started approximately 7–10 days after catheter removal, although individual postoperative protocols vary.

Early exercises should be gentle.

This is not the time to test how hard you can squeeze.

As healing progresses, the programme can gradually move from basic contractions to functional training while standing, walking, coughing, lifting and exercising.

What Should I Expect After the Catheter Comes Out?

The first few days can be confronting.

Some men have relatively little leakage immediately. Others experience considerable leakage, particularly when:

  • standing;
  • walking;
  • coughing;
  • exercising;
  • getting out of a chair; or
  • becoming tired later in the day.

This does not necessarily predict the final outcome.

Continence often improves substantially during the first weeks and months following radical prostatectomy.

Recovery is a marathon measured in millilitres rather than kilometres.

How Successful Is Pelvic Floor Physiotherapy?

This question is more complicated than it initially appears.

Urinary continence frequently improves naturally following prostatectomy, making it difficult for studies to separate the effect of pelvic floor physiotherapy from normal postoperative recovery.

The research is consequently mixed.

The European Association of Urology notes that systematic reviews and trials suggest pelvic floor muscle training can shorten the time to continence recovery, although the evidence regarding supervised training, biofeedback and additional therapies remains inconsistent.

For example, one randomised study cited by the EAU compared supervised physiotherapist-directed pelvic floor training with verbal and written instructions. At 12 months, complete pad-free continence was reported in 65.2% of the supervised group versus 31.6% of the comparison group. This result should not be interpreted as the expected success rate for every patient, because continence definitions, surgical techniques and rehabilitation programmes differ considerably between studies.

A 2023 Cochrane review was considerably more cautious. After reviewing 25 trials, the authors concluded that uncertainty remains regarding the magnitude of benefit from conservative treatments because studies vary considerably in their techniques, combinations of treatments and methodological quality.

The practical message is therefore:

Pelvic floor rehabilitation is an important first-line treatment and may accelerate recovery, but it cannot guarantee continence.

What If Pelvic Floor Exercises Are Not Working?

Persistent leakage does not automatically mean you need to exercise harder.

If continence is failing to improve, the first question should be:

Why am I leaking?

Post-prostatectomy urinary incontinence may result from:

  • weakness of the urinary sphincter;
  • bladder overactivity;
  • urinary urgency;
  • incomplete bladder emptying;
  • bladder-neck or urethral narrowing;
  • a combination of stress and urgency incontinence; or
  • less commonly, other urinary tract problems.

The AUA guideline emphasises distinguishing stress incontinence, where leakage occurs with coughing, walking, lifting or exertion, from urgency incontinence, where leakage accompanies a sudden compelling desire to urinate.

No amount of extra squeezing will correct every one of these problems.

When Should Further Investigation Be Considered?

Further assessment may be appropriate when urinary leakage is:

  • severe;
  • worsening rather than improving;
  • associated with difficulty urinating;
  • associated with significant urgency or frequency;
  • persistent despite appropriate rehabilitation; or
  • sufficiently troublesome that surgical treatment is being considered.

Assessment may include:

Bladder diary

Records fluid intake, urinary frequency, urinary volumes and leakage episodes.

Pad-weight testing

Provides an objective measurement of the amount of urine being lost.

Urinary flow measurement and bladder ultrasound

Can identify poor urinary flow or incomplete bladder emptying.

Cystoscopy

May be recommended when urethral or bladder-neck pathology is suspected.

Urodynamic studies

Can sometimes help distinguish sphincter weakness from bladder dysfunction when the cause of persistent leakage is uncertain or before further treatment.

What Alternatives Are Available if Physiotherapy Is Not Enough?

Pelvic floor rehabilitation is only one part of managing post-prostatectomy incontinence.

Lifestyle and bladder strategies

These may include:

  • appropriate fluid intake;
  • reducing excessive caffeine;
  • avoiding constipation;
  • weight management where appropriate;
  • bladder training;
  • management of urinary urgency; and
  • modifying activities that provoke significant leakage during early recovery.

Continence pads

Modern male continence pads provide discreet protection while continence is recovering.

Using pads does not mean rehabilitation has failed. They are simply a tool for allowing normal activity during recovery.

Penile compression devices

A penile clamp can temporarily reduce leakage in selected men, although these devices must be fitted and used correctly and released regularly to avoid excessive pressure or tissue injury.

Medication

Medication does not generally correct true post-prostatectomy sphincter weakness.

However, medication may be useful when overactive bladder or urinary urgency contributes significantly to leakage.

Biofeedback

Biofeedback can help some patients understand whether they are contracting the correct muscles and how effectively they are doing so.

Electrical stimulation

Electrical stimulation has also been investigated. Some studies suggest an early benefit when combined with pelvic floor training, although evidence remains inconsistent.

When Is Surgery Considered?

A small proportion of men continue to experience significant stress urinary incontinence despite adequate healing and rehabilitation.

If the leakage remains bothersome, further treatment should be discussed rather than simply continuing increasingly intensive pelvic floor exercises indefinitely.

The two principal surgical options are:

Male Sling

A male sling supports and repositions the urethral continence mechanism.

It is generally most suitable for selected men with mild to moderate stress urinary incontinence and adequate residual sphincter function.

Results tend to be less favourable when incontinence is severe. The AUA guideline specifically notes that male sling outcomes are poorer in men with severe sphincteric incontinence.

Artificial Urinary Sphincter

The artificial urinary sphincter (AUS) remains an important treatment for moderate to severe post-prostatectomy stress urinary incontinence.

A fluid-filled cuff is placed around the urethra and controlled by a small pump positioned within the scrotum. The patient operates the pump when he wishes to urinate.

Both male sling surgery and artificial urinary sphincter implantation can significantly reduce pad use and improve quality of life in appropriately selected men.

When Should I Stop Pelvic Floor Rehabilitation?

There is rarely a precise finishing date.

Once continence has returned and pelvic floor control is good, intensive rehabilitation can usually be reduced.

Many men transition from a rehabilitation programme to a simple maintenance programme, incorporating occasional pelvic floor exercises and functional contractions during activities that generate abdominal pressure.

If you are completely dry, have good pelvic floor control and can cough, lift and exercise without leakage, performing increasingly large numbers of exercises is unlikely to provide additional benefit.

The goal is not to become a professional Kegel athlete.

The goal is normal function.

The Bottom Line

Pelvic floor rehabilitation is an important component of recovery following radical prostatectomy.

Learning the technique before surgery can make it easier to identify and activate the correct muscles after the catheter is removed. Following surgery, a structured programme focusing on strength, endurance, rapid contractions, relaxation and functional activation may help accelerate the return of urinary control. Current evidence supports pelvic floor muscle training as part of postoperative management, while acknowledging that the precise additional benefit of intensive supervised physiotherapy remains uncertain.

Just as importantly, more is not always better. Persistent leakage should not automatically be treated with ever-increasing numbers of pelvic floor contractions.

If urinary incontinence remains troublesome despite appropriate rehabilitation, further assessment can determine whether the problem is persistent sphincter weakness, bladder dysfunction or another cause. Treatments ranging from bladder therapy and medication to a male sling or artificial urinary sphincter can then be considered.

A useful rule

Train the pelvic floor, don’t exhaust it.

Correct technique, consistency and functional control matter far more than the number of contractions performed.

This information is intended for general patient education and does not replace individual medical advice. The timing and intensity of pelvic floor rehabilitation should be discussed with your surgeon and/or a physiotherapist experienced in male pelvic health.

Post-Prostatectomy Urinary Incontinence

/0 Comments/in , /by

When urine leakage persists after prostate surgery

Urinary leakage after prostatectomy is common, particularly in the first few weeks and months following surgery. For most men, bladder control progressively improves as the urinary sphincter and pelvic floor recover.

For some men, however, leakage persists and can become a significant physical, social and emotional burden.

The good news is that persistent post-prostatectomy urinary incontinence is treatable, and there are several options ranging from pelvic floor rehabilitation through to highly effective surgical treatments.

What is post-prostatectomy incontinence?

Post-prostatectomy urinary incontinence (PPI) refers to involuntary leakage of urine following surgery to remove the prostate, most commonly radical prostatectomy for prostate cancer.

The most common form is stress urinary incontinence (SUI).

You may notice leakage when:

  • Coughing or sneezing
  • Standing up
  • Walking or exercising
  • Lifting something heavy
  • Getting out of a chair or car
  • Bending over
  • Playing sport
  • During sexual activity or orgasm

Some men also experience urgency urinary incontinence, where a sudden compelling desire to urinate is followed by leakage.

Others have a combination of stress and urgency incontinence.

Why does this happen?

The prostate sits immediately below the bladder and surrounds the urethra. The urinary sphincter mechanism is therefore intimately involved with prostate surgery.

After prostatectomy, continence depends on the remaining external sphincter, pelvic floor muscles and the way the bladder stores and releases urine.

Recovery is a process rather than an on/off switch.

Most men experience substantial improvement during the first year, although the rate and extent of recovery varies between individuals. A small proportion of men continue to have bothersome leakage that requires active treatment.

How severe is the leakage?

The first step is to understand exactly what type of leakage you have and how much urine you are losing.

A consultation should look at:

1. Your symptoms

We want to know:

  • When did the leakage begin?
  • Is it improving, stable or getting worse?
  • Does it occur with coughing, movement or exercise?
  • Do you experience urgency?
  • How frequently do you urinate?
  • Do you get up at night?
  • Do you have difficulty emptying your bladder?
  • Do you leak during sexual activity or orgasm?
  • How much does the problem interfere with your lifestyle?

A validated questionnaire such as the ICIQ-UI Short Form can provide a standardised measure of symptoms and their impact.

Objective assessment

It is useful to measure your incontinence rather than relying solely on how many pads you use.

Different men use different numbers of pads, and a pad that is changed for comfort may contain very little urine.

Pad weight testing

A pad weight test provides a more objective measurement of urine loss.

The principle is simple:

1 gram increase in pad weight ≈ 1 mL of urine.

Depending on the clinical question, testing can be performed over a defined period or as a 24-hour pad weight assessment during normal daily activities.

For example:

Dry pads: 250 g
Used pads: 650 g

Urine loss = 400 g ≈ 400 mL

Pad testing can help:

  • Quantify the severity of leakage
  • Establish a baseline
  • Monitor improvement
  • Compare the result before and after treatment

Pad weight testing is recommended as one of the objective tools for assessing male urinary incontinence.

Why pad weight can be more useful than “number of pads”

One man’s “three pads a day” may represent a few drops on each pad.

Another man’s three pads may be completely saturated.

The number of pads therefore tells only part of the story.

The weight tells us how much urine is actually being lost.

Bladder diary

A 3-day bladder diary can be remarkably informative.

You record:

  • What and how much you drink
  • Time of each drink
  • Time of each urination
  • Volume passed
  • Urgency
  • Episodes of leakage
  • Activity associated with leakage
  • Pad changes
  • Night-time urination

The diary helps identify patterns that may not be obvious during a consultation.

It can distinguish, for example, between:

“I am leaking because my sphincter is weak”

and

“I am leaking because my bladder is filling rapidly and becoming overactive.”

Bladder diaries are an established method for objectively assessing frequency, voided volumes, urine production and urinary leakage.

Ultrasound assessment

An ultrasound examination can provide important additional information.

A particularly useful measurement is the post-void residual (PVR).

This tells us how much urine remains in the bladder after you have urinated.

Why does this matter?

Persistent urine in the bladder may indicate:

  • Poor bladder emptying
  • Bladder outlet obstruction
  • Reduced bladder contractility
  • Dysfunctional voiding

Ultrasound may also be used to assess the urinary tract and, where clinically appropriate, investigate other anatomical abnormalities.

Measurement of PVR is recommended in the assessment of male urinary incontinence.

Urodynamic testing

Sometimes the bladder and sphincter need to be examined in considerably more detail.

This is where urodynamics can be extremely useful.

Urodynamic testing measures how the bladder and urethra behave during filling and emptying.

It can assess:

  • Bladder capacity
  • Bladder sensation
  • Bladder compliance
  • Detrusor overactivity
  • Bladder pressure
  • Urinary flow
  • Bladder emptying
  • Sphincter function
  • Stress leakage
  • Bladder outlet obstruction

Why is this important?

Not all post-prostatectomy leakage is caused by the same problem.

A man may have:

Sphincter weakness

or

Overactive bladder

or

Poor bladder compliance

or

Impaired bladder contractility

or a combination of these.

Urodynamics can help distinguish bladder dysfunction from sphincteric insufficiency and can be particularly useful when the diagnosis is uncertain, bladder emptying is abnormal, or invasive treatment is being considered.

Urodynamics is not necessarily required for every man with straightforward stress incontinence.

It should be used selectively when the results are likely to influence diagnosis, counselling or treatment.

Pelvic floor muscle training

The pelvic floor is part of your continence mechanism

Pelvic floor muscle training (PFMT) is an important component of recovery after prostatectomy.

The pelvic floor muscles help support the urethra and contribute to urinary control.

The aim is not simply to perform hundreds of random “Kegels”.

Effective rehabilitation involves learning to:

  1. Identify the correct muscles
  2. Contract them correctly
  3. Hold the contraction
  4. Relax completely
  5. Coordinate the contraction with movement and changes in abdominal pressure
  6. Use the muscles appropriately during activities that trigger leakage

A specialised pelvic floor physiotherapist can be extremely helpful.

Timing matters

Pelvic floor exercises can be started before prostatectomy and should be continued after surgery.

Following catheter removal, pelvic floor muscle exercises or formal pelvic floor muscle training should be offered to men recovering from radical prostatectomy. Evidence suggests that they can accelerate the return of continence, particularly during the earlier stages of recovery.

However, pelvic floor exercises are not a magic switch.

If significant stress incontinence persists despite appropriate rehabilitation, it is important to reassess the situation rather than simply continuing exercises indefinitely.

When should surgery be considered?

Continence often continues to improve during the first year after prostatectomy.

For men with bothersome stress urinary incontinence who are not improving despite conservative treatment, surgical treatment can be considered from around six months, particularly when the incontinence is severe.

For persistent bothersome incontinence, surgical treatment should generally be offered by approximately 12 months rather than waiting indefinitely for further spontaneous improvement.

The exact timing should be individualised.

Surgical treatment

There is no single operation that is right for every man.

The choice depends on:

  • Severity of leakage
  • Pad weight
  • Time since prostatectomy
  • Previous radiation therapy
  • Urethral anatomy
  • Bladder function
  • Previous continence surgery
  • Manual dexterity
  • Patient expectations and preferences

The major surgical options include:

1. Male sling

A male sling supports and/or repositions the urethra to improve urinary control.

It is generally most suitable for mild to moderate stress urinary incontinence.

A sling may be particularly attractive to men who:

  • Have relatively low-volume leakage
  • Have not received pelvic radiation
  • Have good bladder function
  • Prefer a treatment without a mechanical pump

However, male slings are not routinely recommended for severe stress incontinence, where outcomes are generally less reliable than with an artificial urinary sphincter.

2. Artificial urinary sphincter

For significant or severe post-prostatectomy stress incontinence, the artificial urinary sphincter (AUS) remains the benchmark surgical treatment.

The device consists of:

  • A cuff around the urethra
  • A small control pump in the scrotum
  • A pressure-regulating balloon

When the cuff is inflated, the urethra is closed.

When you want to urinate, you squeeze the pump.

The cuff temporarily opens, allowing urine to pass.

It then automatically closes again.

Who is an AUS suitable for?

An AUS can be considered for men with mild through severe stress urinary incontinence, particularly when conservative treatment has failed.

Before implantation, the patient needs sufficient manual dexterity and cognitive ability to operate the device.

What are the disadvantages?

An AUS is a mechanical implant.

Potential complications include:

  • Infection
  • Urethral erosion
  • Mechanical failure
  • Persistent or recurrent leakage
  • Urethral atrophy
  • Need for revision or replacement

The device can provide excellent long-term continence, but patients should understand that it is not necessarily a “fit it and forget it” solution. Reoperations become more common as the device ages.

3. Adjustable continence devices

Adjustable balloon systems are another option in selected men.

These devices provide external compression around the urethra and can be adjusted following implantation.

They may be considered in selected patients, particularly those with mild incontinence and appropriate anatomy.

The evidence base is less extensive than that for the AUS, and device complications and explantation need to be discussed carefully.

4. Urethral bulking injections

Injectable bulking agents have historically been used to try to improve urethral closure.

They are minimally invasive, but their effectiveness in men following prostatectomy is limited.

Patients should understand that cure is uncommon and durability is poor compared with established surgical treatments.

They are therefore not generally considered the preferred treatment for significant post-prostatectomy stress incontinence.

What if you have urgency as well?

Not every leak after prostatectomy is caused by the sphincter.

Some men develop overactive bladder symptoms, including:

  • Urgency
  • Frequency
  • Nocturia
  • Urgency-associated leakage

This may require treatment directed at the bladder rather than the sphincter.

Treatment may include:

  • Bladder training
  • Fluid modification
  • Pelvic floor rehabilitation
  • Medication
  • Selected minimally invasive treatments for overactive bladder

If urgency is the dominant problem, it should be treated as an overactive bladder rather than assuming that an operation on the sphincter will solve everything.

What about men who have had radiotherapy?

Previous pelvic radiotherapy is particularly important when choosing surgery.

Radiation can affect the tissues and urethral blood supply and may increase the risk of complications and treatment failure.

For men with stress incontinence following radiotherapy, an artificial urinary sphincter is generally preferred over a male sling or adjustable balloon device.

This is one reason why your previous prostate cancer treatment is an important part of the surgical decision.

The decision is about more than pads

The goal of treatment is not simply:

“How many pads can we get you down to?”

It is about getting you back to the life you want to live.

That might mean being able to:

  • Exercise without worrying about leakage
  • Play golf or tennis
  • Go out without carrying spare pads
  • Travel confidently
  • Sleep without constantly worrying about leakage
  • Wear the clothes you want
  • Be intimate with your partner without anxiety

The appropriate treatment depends on both the objective severity of the incontinence and how much it affects your quality of life.

A practical assessment pathway

Step 1

Understand the symptoms

Stress leakage? Urgency? Mixed symptoms? Night-time leakage?

Step 2

Measure the problem

Validated questionnaire + bladder diary + pad weight.

Step 3

Check bladder emptying

Ultrasound and post-void residual.

Step 4

Assess pelvic floor function

Pelvic floor assessment and physiotherapy where appropriate.

Step 5

Look deeper when necessary

Urodynamics, and additional investigations such as cystoscopy when clinically indicated.

Step 6

Treat the cause

Bladder-directed treatment for urgency/detrusor dysfunction.

Sphincter-directed treatment for genuine stress incontinence.

Step 7

Consider surgery when appropriate

  • Mild–moderate SUI: male sling may be appropriate in selected men
  • Moderate–severe SUI: artificial urinary sphincter is often the preferred option
  • Severe SUI: AUS generally favoured over sling
  • Previous radiotherapy: AUS generally preferred
  • Failed sling: AUS is usually the most effective subsequent option

Don’t just put up with it

Urinary leakage after prostatectomy is common, but persistent incontinence should not simply be accepted as the price of prostate cancer treatment.

If leakage is interfering with your life, there is a structured pathway to determine exactly what is happening and what can be done about it.

A combination of symptom assessment, bladder diary, pad weight measurement, ultrasound, pelvic floor assessment and, where appropriate, urodynamics can provide a much clearer picture.

From there, treatment can be tailored to the individual, ranging from rehabilitation through to reconstructive continence surgery.

The aim is simple: better bladder control, greater confidence and getting you back to doing the things that matter to you.

When should you seek specialist assessment?

Consider seeing a urologist specialising in male continence if:

  • Significant leakage persists beyond the early recovery period
  • You are still using multiple pads several months after surgery
  • Leakage is affecting exercise, work, travel or intimacy
  • You have both urgency and stress leakage
  • You have difficulty emptying your bladder
  • You have previously had pelvic radiation
  • Your incontinence is getting worse rather than better
  • You are considering surgical treatment

Mid-Urethral Slings for Stress Urinary Incontinence: What Is the Current Australian Position?

/0 Comments/in , , /by

Patient information for Australian women | Reviewed 22 September 2026

The word “mesh” can understandably cause concern. Public discussion has often grouped together several very different products and operations. A mid-urethral sling used to treat female stress urinary incontinence is not the same operation as transvaginal mesh used to repair pelvic organ prolapse, and it is also different from a single-incision mini-sling.

The Urological Society of Australia and New Zealand (USANZ) supports the continued availability of mid-urethral slings in Australia as one treatment option for appropriately selected women. That support is not unconditional: USANZ emphasises appropriate clinical governance, surgeon credentialing, informed consent, multidisciplinary review where appropriate, and monitoring of patient outcomes.

What is stress urinary incontinence?

Stress urinary incontinence, or SUI, is leakage caused by an increase in abdominal pressure, for example when coughing, sneezing, laughing, exercising or lifting. It is different from urge incontinence, in which leakage is associated with a sudden compelling need to pass urine.

An accurate diagnosis matters. Some women have both stress and urgency symptoms, difficulty emptying the bladder, prolapse, recurrent infections or previous pelvic surgery. A consultation may therefore include a history, examination, bladder diary, urine testing, measurement of residual urine and, in selected or complex cases, urodynamic studies or cystoscopy.

What is a mid-urethral sling?

A mid-urethral sling is a narrow strip of permanent synthetic polypropylene mesh placed beneath the middle part of the urethra. It provides support during coughing, exercise and other activities that raise abdominal pressure.

The two established approaches are:

  • Retropubic sling: the tape passes behind the pubic bone.
  • Transobturator sling: the tape passes through the obturator region towards the groin.

These approaches have different risk profiles. The retropubic route has a greater risk of bladder perforation and short-term voiding difficulty, while the transobturator route has a greater association with groin or thigh pain. The most appropriate approach depends on the woman’s anatomy, previous operations, clinical circumstances and preferences.

What does USANZ say?

USANZ states that mid-urethral slings have an established evidence base for relative safety and effectiveness and should remain available in Australia for the treatment of female SUI. In its 2023 statement, USANZ specifically linked continued use to the clinical-governance improvements introduced in Australia since 2018, including:

  • appropriate surgeon credentialing
  • careful patient selection
  • discussion through multidisciplinary processes where indicated
  • genuine informed consent
  • monitoring of outcomes through the Australasian Pelvic Floor Procedure Registry.

This position supports patient choice, not routine surgery for every woman. Conservative care should usually be considered first, and non-mesh alternatives must be discussed when surgery is being considered.

What is the TGA position?

The Therapeutic Goods Administration (TGA) regulates medical devices in Australia. Surgical mesh is classified as a Class III medical device, the highest-risk classification, requiring more stringent evidence and regulatory assessment.

Following its safety reviews, the TGA removed certain transvaginal prolapse mesh products and single-incision mini-slings from routine supply. This did not amount to a ban on established retropubic and transobturator mid-urethral slings for SUI. The TGA’s current register includes eligible Class III urogynaecological mesh devices intended for SUI; the precise indication must always be checked in the device’s approved Instructions for Use.

The TGA requires manufacturers to provide patient information leaflets and implant cards for these devices. A woman receiving a sling should know the product used and should retain her implant card.

How effective is a mid-urethral sling?

Mid-urethral sling surgery is one of the most extensively studied operations for female SUI. Australian safety and quality guidance describes it as highly effective in the short and medium term, with long-term studies showing sustained patient satisfaction for many women.

No operation can guarantee a cure. Outcomes depend on the definition of success, length of follow-up, type of sling, surgeon experience and the individual patient. Stress leakage may persist or recur, and urgency symptoms may remain, improve or occasionally develop after surgery.

What are the risks?

Most women do not develop a serious complication, but complications can be significant and may occur early or years later. Potential risks include:

  • bleeding, infection and anaesthetic complications
  • temporary or persistent difficulty emptying the bladder, sometimes requiring catheterisation or further surgery
  • bladder or urethral injury
  • urinary tract infection
  • new or worsened urinary urgency or urge incontinence
  • persistent or recurrent stress incontinence
  • vaginal mesh exposure
  • mesh erosion into the urethra or bladder
  • pelvic, vaginal, groin or thigh pain
  • pain during intercourse
  • rarely, injury to major blood vessels, bowel or other pelvic structures.

Mesh is intended to remain permanently. If a mesh complication develops, partial or complete removal may be considered, but complete removal can be technically difficult or impossible and may require more than one operation. Removal may not fully resolve pain and can cause stress incontinence to recur.

Seek medical assessment if you develop persistent pelvic or groin pain, pain during intercourse, vaginal bleeding or discharge, recurrent urinary infections, difficulty passing urine, blood in the urine, or recurrent leakage after sling surgery.

What are the alternatives?

Treatment should be individualised. Options include:

  • no active treatment or the use of continence products
  • lifestyle measures, including weight management, treatment of constipation and chronic cough, and smoking cessation
  • supervised pelvic-floor muscle training, usually for at least three months
  • a continence pessary in suitable women
  • urethral bulking injections, which are less invasive but generally less durable and may need repeating
  • an autologous fascial sling using the patient’s own tissue
  • Burch colposuspension using sutures and native tissue.

Autologous fascial sling and colposuspension avoid permanent synthetic mesh but usually involve a longer operation and recovery and have their own risks, including voiding difficulty. There is no single best operation for every woman.

Shared decision-making and informed consent

Before proceeding, a woman should have enough time and balanced information to consider:

  • whether her symptoms are predominantly stress, urgency or mixed incontinence
  • conservative, mesh and non-mesh options
  • the expected benefits and limitations of each option
  • short- and long-term risks, including mesh-specific complications
  • the surgeon’s training and experience with the proposed procedure and alternatives
  • what follow-up will occur and how complications would be managed
  • the name and TGA registration status of the proposed device.

A second opinion is reasonable, particularly if symptoms are complex, previous continence surgery has failed, chronic pelvic pain is present, or the available options remain unclear.

The balanced Australian position

Mid-urethral slings are not appropriate for every woman, but neither are they prohibited in Australia. USANZ supports their continued availability for carefully selected patients within strong clinical-governance systems. The TGA continues to regulate eligible SUI sling devices as Class III medical devices and requires enhanced patient information and traceability.

The most important principles are an accurate diagnosis, consideration of conservative care, a balanced discussion of mesh and non-mesh alternatives, surgeon credentialing, informed consent and structured follow-up.
