Urinary Incontinence After Prostatectomy and Salvage Radiotherapy

/0 Comments/in , , /by

Why leakage may become more complex after both treatments

Urinary leakage after radical prostatectomy is common in the early recovery period and usually improves with healing and pelvic floor rehabilitation. Some men, however, require salvage radiotherapy because their PSA remains detectable or rises after surgery.

Radiotherapy can help control recurrent prostate cancer, but it may also affect tissues that have already been altered by surgery. Radiation can cause progressive scarring, reduced blood supply and loss of elasticity in the urethra, bladder neck and bladder. These effects may develop months or even years later.

As a result, leakage after prostatectomy and salvage radiotherapy is not always caused by a weak urinary sphincter alone. A man may have:

  • Stress urinary incontinence: leakage with coughing, standing, lifting, walking or exercise because the sphincter does not close effectively.
  • Urgency urinary incontinence: leakage accompanied by a sudden, difficult-to-defer urge, often caused by an overactive or irritated bladder.
  • Overflow leakage: leakage associated with poor bladder emptying, a weak bladder muscle or obstruction.
  • Mixed incontinence: a combination of stress and urgency leakage.
  • Radiation-related complications: bladder-neck contracture, urethral stricture, radiation cystitis, poor bladder compliance, fistula, tissue necrosis or, in severe cases, a severely damaged bladder outlet.

Correctly identifying the cause is essential. Tightening the outlet when the bladder cannot store or empty safely may replace one problem with another.

When should the problem be assessed?

Continence can continue to improve during the first year after prostatectomy. Pelvic floor muscle training should begin early, and surgical treatment may be considered as early as six months when severe leakage is clearly not improving. Persistent, bothersome stress incontinence at approximately 12 months deserves formal assessment.

Following salvage radiotherapy, earlier review is appropriate if there is:

  • worsening leakage;
  • blood in the urine;
  • recurrent urinary infection;
  • pain, burning or severe urgency;
  • a weak stream or difficulty emptying;
  • urinary retention;
  • pelvic or perineal pain; or
  • urine leaking through an abnormal opening.

Visible haematuria, fever, inability to pass urine or severe pain requires prompt medical attention.

Investigating incontinence after salvage radiotherapy

1. A careful history

The first step is to establish what type of leakage is occurring, when it began and whether it changed after radiotherapy. Important questions include:

  • Is leakage triggered by activity, or by urgency?
  • How many pads are used, and how wet are they?
  • Is the patient dry at night or when lying down?
  • Is there a weak stream, straining or incomplete emptying?
  • Are there recurrent infections, haematuria or pelvic pain?
  • Were there previous bladder-neck or urethral procedures?
  • How much does leakage affect work, exercise, sleep, intimacy and quality of life?

Manual dexterity and cognition are also important if an artificial urinary sphincter is being considered, because the patient must be able to locate and operate a small scrotal pump.

2. Bladder diary and pad assessment

A three-day bladder diary records fluid intake, voided volumes, urgency and leakage. Pad number gives a useful impression, but pads differ greatly. A 24-hour pad-weight test can quantify the actual volume lost and help grade severity and monitor progress.

3. Examination and basic tests

Assessment commonly includes:

  • abdominal, genital, perineal and neurological examination;
  • observation for leakage while coughing or standing with a comfortably full bladder;
  • urinalysis and urine culture when infection is suspected;
  • uroflowmetry;
  • ultrasound measurement of the post-void residual; and
  • renal function testing or upper-tract imaging when clinically indicated.

4. Cystoscopy

Cystoscopy is particularly important before continence surgery in a previously irradiated urinary tract. It allows the urologist to inspect the urethra, bladder neck and bladder for:

  • urethral stricture or bladder-neck contracture;
  • radiation damage, stones or tumour;
  • erosion from a previous implant;
  • tissue quality and sphincter appearance; and
  • fistula or necrosis in complex cases.

Any clinically important obstruction or unstable urethral disease usually needs to be treated and shown to be stable before an anti-incontinence device is implanted.

What is the role of urodynamic studies?

Urodynamics is not mandatory for every man with straightforward stress leakage. It becomes more useful when symptoms are mixed, the diagnosis is uncertain, previous radiation has made the situation more complex, or the result may change treatment.

The study can assess:

  • stress leakage and sphincter weakness;
  • involuntary bladder contractions;
  • bladder capacity and sensation;
  • reduced bladder compliance or unsafe storage pressures;
  • obstruction;
  • weak bladder contraction; and
  • the ability of the bladder to empty against a future sling or sphincter cuff.

Urodynamics is especially worth considering when there is marked urgency, nocturnal leakage, retention, a raised residual, poor flow, recurrent infection, prior outlet reconstruction or concern about a small, painful or poorly compliant radiation-damaged bladder.

The test does not simply decide whether a man “qualifies” for an operation. Its value is in identifying bladder dysfunction that should be treated first or a bladder that may not tolerate additional outlet resistance.

Initial and non-surgical management

Pelvic floor rehabilitation

Supervised pelvic floor muscle training can improve control and teach correct muscle activation. It is most useful early after prostatectomy but may still improve coping and control later. Repeated forceful exercises are not always better; poor technique can worsen pelvic tension or urgency.

Bladder and lifestyle measures

Management may include weight reduction where relevant, treating constipation, moderating caffeine and alcohol, adjusting the timing of fluids and diuretics, bladder training and treating urinary infection. Antimuscarinic medication or a beta-3 agonist may help an overactive-bladder component, but medication does not restore a damaged sphincter.

Pads, sheaths and clamps

Absorbent pads remain a practical option for mild leakage or while awaiting treatment. A condom drainage sheath can direct urine into a leg bag when penile skin and anatomy permit.

A penile clamp may provide short-term control for selected men with good sensation, intact skin and adequate bladder emptying. It must be released regularly and should not be used overnight. Extra caution is required after radiation because pressure injury may heal poorly.

Catheter options

Catheters manage drainage; they do not repair stress incontinence. They may nevertheless be appropriate when there is retention, very poor emptying, severe frailty, failed reconstruction or a need for temporary urinary control.

Intermittent self-catheterisation

Intermittent self-catheterisation is generally preferred when the bladder fails to empty but the patient has sufficient dexterity and urethral access. It avoids a continuously indwelling tube, although irradiated strictures or a false passage may make catheterisation difficult.

Long-term urethral catheter

An indwelling urethral catheter may be necessary in selected patients, but long-term use can cause infection, discomfort, blockage, bladder stones, urethral erosion and further outlet damage. A catheter passing through an activated AUS cuff can also cause serious urethral erosion; healthcare providers must be told that an AUS is present and the device should be deactivated before urethral instrumentation.

Suprapubic catheter

A suprapubic catheter enters the bladder through the lower abdomen. For long-term drainage it often avoids continuing urethral pressure and may be easier to manage than a urethral catheter. It still requires regular changes and carries risks including infection, blockage, bladder stones, leakage and skin problems.

Male sling versus artificial urinary sphincter

Male sling

A male sling supports and repositions or compresses the urethra. Its advantages include no scrotal pump and no need to operate the device each time the patient urinates. In carefully selected, non-irradiated men with mild-to-moderate stress incontinence, a sling can be effective.

However, previous pelvic radiotherapy is a recognised predictor of poorer sling outcomes. Fibrosis limits urethral mobility and tissue recovery, and moderate-to-severe leakage further reduces success. A sling may still be discussed in a highly selected patient with very mild leakage, good residual sphincter function and a stable, healthy-looking urethra, but expectations must be conservative.

Artificial urinary sphincter (AUS)

The AUS consists of a fluid-filled cuff around the urethra, a pressure-regulating balloon and a pump in the scrotum. The cuff stays closed to control leakage. The patient squeezes the pump to open it temporarily when passing urine.

For men with moderate-to-severe stress incontinence, the AUS remains the most established surgical treatment. Importantly, the AUA/GURS/SUFU guideline recommends offering an AUS rather than a male sling or adjustable balloons to men seeking surgery after primary, adjuvant or salvage radiotherapy.

Radiation does not make AUS implantation impossible, but outcomes are less predictable than in non-irradiated men. Radiation increases the risks of urethral erosion, infection, tissue atrophy, revision and device removal. Mechanical parts also have a limited lifespan, so further surgery may eventually be required.

Practical comparison

Consideration Male sling Artificial urinary sphincter
Best-established role Mild-to-moderate stress leakage in selected men Moderate-to-severe stress leakage
Previous salvage radiotherapy Lower success; generally not preferred Guideline-preferred surgical option, with higher complication risk than in non-irradiated men
Patient operation No pump Scrotal pump must be squeezed for each void
Manual dexterity required Minimal Yes
Retention risk Possible Possible if device is not cycled correctly or obstruction develops
Long-term considerations Persistent leakage or failure may require AUS Mechanical failure, erosion, infection or atrophy may require revision or removal

Neither operation guarantees complete dryness. The choice should consider pad weight, bladder function, urethral health, prior strictures or surgery, dexterity, patient priorities and the reconstructive surgeon’s assessment.

When an AUS or sling is not enough

A small group of men develop a severely scarred, painful or repeatedly obstructed outlet, sometimes called a devastated bladder outlet. This may include recurrent bladder-neck contracture or urethral stricture, fistula, radionecrosis, repeated AUS erosion, severe radiation cystitis or an unsafe low-capacity bladder.

Further implant surgery may then be unlikely to succeed. The priority changes from preserving normal voiding to obtaining dependable drainage, protecting the kidneys and improving quality of life.

Options at a specialist reconstructive centre may include:

  • long-term suprapubic drainage;
  • closure of the bladder neck with a suprapubic catheter in selected cases;
  • a catheterisable abdominal channel in carefully selected patients;
  • an ileal conduit, in which urine drains through a short segment of bowel to a urostomy bag on the abdomen;
  • another form of continent urinary diversion in selected fit patients; or
  • cystectomy with urinary diversion when the bladder is severely painful, contracted, bleeding, fistulating or otherwise unsalvageable.

These are major, irreversible procedures with substantial risks. They should be considered only after detailed imaging and functional assessment, review of cancer status, discussion with an experienced reconstructive team and consultation with a stomal therapy nurse.

A sensible treatment pathway

  1. Define the leakage: stress, urgency, overflow or mixed.
  2. Measure its severity: diary, pads and preferably pad weight.
  3. Check storage and emptying: urine testing, flow and residual; use urodynamics when the findings may alter treatment.
  4. Inspect the outlet: cystoscopy before implant surgery, particularly after radiation.
  5. Treat infection, obstruction and bladder dysfunction first.
  6. Use conservative or catheter strategies when appropriate.
  7. For persistent radiated stress incontinence, discuss AUS as the usual preferred operation.
  8. Reserve sling surgery for exceptional, carefully selected radiated patients after frank counselling.
  9. Refer severe outlet or bladder destruction to a high-volume reconstructive centre to discuss reconstruction versus diversion.

The take-home message

Urinary incontinence after prostatectomy and salvage radiotherapy is treatable, but it needs more than a pad count and a one-size-fits-all operation. The bladder, sphincter and urethra must each be assessed.

For straightforward sphincter weakness after radiation, the artificial urinary sphincter usually offers the most reliable surgical option, although radiation increases the likelihood of erosion and future revision. A male sling is less invasive but is less dependable in irradiated tissue. When the outlet or bladder is severely damaged, catheter drainage, bladder-neck closure or urinary diversion may provide a safer and more durable solution than repeated continence procedures.

This article provides general information and does not replace an individual assessment. Treatment should be tailored to the patient’s symptoms, examination, bladder function, urethral condition, cancer status and personal priorities.

Radical Prostatectomy After Radiation Therapy for Prostate Cancer

/0 Comments/in , /by

When prostate cancer returns after radiotherapy

Radiotherapy, whether external-beam radiation or brachytherapy can provide excellent long-term control of localised prostate cancer. However, a rising prostate-specific antigen (PSA) after treatment may indicate that the cancer has returned.

This does not automatically mean that the cancer is still in the prostate, nor does every PSA rise require immediate treatment. Recurrence may be confined to the prostate, present in lymph nodes or bones, or involve more than one site. Some recurrences also progress slowly enough that surveillance may be appropriate.

When clinically significant cancer is proven to have returned within the irradiated prostate, with no evidence of spread elsewhere, removal of the prostate may still offer a chance of cure. This operation is called a salvage radical prostatectomy.

What is a salvage radical prostatectomy?

A salvage radical prostatectomy removes the entire prostate and seminal vesicles after previous prostate radiotherapy. Depending on the cancer and imaging findings, pelvic lymph nodes may also be removed.

The operation may be performed using robotic-assisted or open surgery. A robotic approach can improve magnification and access, but it does not remove the biological effects of previous radiation. Surgeon and centre experience are therefore more important than the label attached to the surgical technique.

Salvage surgery is technically more difficult than a prostatectomy performed before radiotherapy. Radiation can cause:

  • scarring and fibrosis around the prostate;
  • loss of the normal tissue planes between the prostate, bladder and rectum;
  • reduced tissue blood supply;
  • poorer tissue healing; and
  • pre-existing damage to urinary, erectile or bowel function.

For these reasons, salvage prostatectomy should generally be undertaken in a centre with specific experience in complex prostate cancer surgery and access to multidisciplinary care.

When might salvage surgery be considered?

The aim is to identify a man who has a meaningful risk from his recurrent cancer, but whose disease still appears curable with local treatment. Possible indications include:

  • a rising PSA after radiotherapy, commonly assessed using the Phoenix definition: a PSA rise of at least 2 ng/mL above the lowest PSA reached after treatment;
  • prostate cancer confirmed on biopsy after radiotherapy;
  • imaging suggesting that the recurrence is confined to the prostate or immediate surrounding tissues;
  • no evidence of distant metastatic disease;
  • a life expectancy long enough to benefit from curative treatment, often more than 10 years;
  • good general health and fitness for major surgery;
  • acceptable baseline bladder function; and
  • willingness to accept a higher risk of urinary and sexual side effects than with a primary prostatectomy.

Factors such as the PSA level, PSA doubling time, interval since radiotherapy, biopsy Grade Group, clinical stage and the original cancer characteristics help estimate whether salvage treatment is likely to be worthwhile.

Assessment before considering surgery

A rising PSA is the beginning of the assessment—not the final diagnosis. Investigations commonly include:

Review of the original treatment

The radiation dose and field, use of brachytherapy, previous androgen-deprivation therapy, original biopsy grade and pre-treatment imaging should all be reviewed.

Multiparametric MRI

MRI can help identify the site and extent of a local recurrence, assess the seminal vesicles, bladder neck and rectal interface, and guide biopsy. Interpretation after radiation can be challenging and benefits from specialist radiological expertise.

PSMA PET/CT

PSMA PET/CT is used to look for disease in lymph nodes, bones or other organs. Finding metastatic disease usually changes the treatment plan and may mean that removing the prostate would not provide the expected benefit. Very small-volume disease can still be below the resolution of any scan.

Prostate biopsy

Major guidelines recommend pathological confirmation before potentially morbid local salvage therapy. Biopsy can confirm viable cancer, determine its grade and help distinguish clinically important recurrence from post-radiation change. Both targeted and systematic sampling may be considered.

Urinary-function assessment

Assessment may include symptom scores, urine testing, urinary-flow measurement, residual urine ultrasound and cystoscopy. Urodynamic testing may be helpful when there is significant urgency, leakage, poor flow, retention or uncertainty about bladder function.

Who may not be a good candidate?

Salvage prostatectomy is less likely to be appropriate when:

  • metastatic or extensive nodal disease is present;
  • the cancer is unlikely to be completely removable;
  • life expectancy is limited by age, frailty or other illness;
  • the recurrence is low risk and unlikely to threaten health;
  • severe urinary or bowel damage already exists after radiation; or
  • the anticipated harms of surgery outweigh the probability of cancer control.

These are not absolute rules. Individual circumstances should be reviewed by a multidisciplinary team involving urology, radiation oncology, medical oncology, radiology and pathology.

What are the potential benefits?

For carefully selected men, salvage prostatectomy can:

  • remove the recurrent cancer and provide complete pathological staging;
  • provide durable PSA control without immediately committing the patient to lifelong hormonal therapy; and
  • offer a possibility of cure when disease is truly confined to the prostate.

Published results vary considerably because most evidence comes from retrospective series involving highly selected patients. The European Association of Urology reports five-year biochemical recurrence-free estimates broadly around 41–52% in a large contemporary systematic review, while older selected series have reported ranges of approximately 47–82%. A broader meta-analysis of all local salvage approaches found roughly 50–60% five-year recurrence-free survival, without clear evidence that one approach was oncologically superior. These figures should not be interpreted as a personal prediction.

Cancer control is generally more favourable when the PSA is lower, the recurrent tumour is organ-confined, the cancer grade is lower, the PSA doubling time is longer and there is no nodal or distant disease.

Side effects and complications

Complication rates vary with baseline function, radiation type and dose, disease extent, surgical technique, definitions used in studies and surgeon experience. Results from specialist centres may not apply everywhere.

Urinary incontinence

Loss of urinary control is one of the most important risks. Radiation may already have affected the sphincter, bladder and urethral tissues, and surgery removes the prostate through which the urethra passes.

Leakage may range from mild stress incontinence to severe continuous leakage. Pelvic-floor rehabilitation can help, but some men may later require a male sling or artificial urinary sphincter. Continence outcomes reported in the literature vary widely because studies use different definitions; the risk of significant or persistent leakage is clearly higher than after primary prostatectomy.

Erectile dysfunction

Erectile function is often already impaired by radiotherapy, age, vascular disease or hormonal treatment. Preservation of the erectile nerves may be unsafe or technically impossible because of tumour location and radiation fibrosis. Consequently, erectile dysfunction after salvage prostatectomy is very common and recovery of unassisted erections is uncommon.

Rehabilitation and treatment options include tablets, vacuum devices, penile injections and penile prosthesis surgery. As with any radical prostatectomy, ejaculation and natural fertility are lost because the prostate and seminal vesicles are removed.

Bladder-neck contracture or urethral narrowing

Scar tissue may develop where the bladder is reconnected to the urethra. This can cause a weak stream, straining, incomplete emptying, retention or recurrent infection. Treatment may require endoscopic incision or dilatation, sometimes more than once. Repeated procedures can worsen incontinence.

Urine leak and delayed healing

The new bladder-to-urethra join may heal slowly because irradiated tissues have reduced blood supply. A urinary catheter may need to remain in place longer, and imaging may be required before its removal. Persistent leakage can require drainage or further intervention.

Rectal injury and urinary fistula

The rectum can be densely adherent to the prostate after radiotherapy. Rectal injury is uncommon in expert contemporary practice but occurs more often than during primary prostatectomy and can be serious. It may require repair, temporary bowel diversion or, rarely, more extensive surgery. An abnormal connection between the urinary tract and rectum—a rectourinary fistula—is rare but particularly difficult to treat.

Other surgical risks

Other possible complications include bleeding or transfusion, infection, blood clots, lymphocele after lymph-node dissection, injury to nearby structures, anaesthetic complications, chronic pelvic pain and the need for further procedures.

Cancer may still recur

Even when preoperative imaging suggests local disease, microscopic cancer may already exist outside the prostate. PSA may therefore remain detectable or rise again after surgery. Further treatment—such as hormonal therapy, systemic therapy or selected metastasis-directed treatment—may still be required.

Are there alternatives?

Depending on the cancer, previous treatment, anatomy, urinary function and patient priorities, alternatives may include:

  • active monitoring for a slow or low-risk recurrence;
  • androgen-deprivation therapy, sometimes with additional systemic treatment;
  • salvage brachytherapy or stereotactic re-irradiation;
  • cryotherapy;
  • high-intensity focused ultrasound (HIFU); or
  • focal salvage treatment in carefully selected cases.

No single salvage treatment is best for every patient. Available studies are mostly non-randomised and use differing definitions. A large meta-analysis found broadly similar five-year cancer control among local salvage methods, but severe urinary toxicity was higher after salvage prostatectomy than after modern re-irradiation approaches. Treatment should therefore be selected through shared decision-making rather than on cancer-control figures alone.

The bottom line

Radical prostatectomy after prostate radiotherapy is possible and can be curative, but it is not a routine operation. The best candidate is generally a fit man with biopsy-proven, clinically significant recurrence confined to the prostate, no metastatic disease on appropriate staging, a meaningful life expectancy and a clear understanding of the potential functional consequences.

Accurate staging, confirmation by biopsy, assessment of baseline urinary function and review by an experienced multidisciplinary team are essential. The decision must balance the chance of durable cancer control against the higher risks of urinary incontinence, erectile dysfunction, urinary narrowing, poor healing and rectal complications.

This article provides general information and does not replace individual medical advice. Recommendations should be tailored to the pathology, imaging, previous radiation treatment, general health and preferences of each patient.

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.
