Clips for Benign Prostatic Enlargement: A Minimally Invasive Treatment That Preserves Ejaculation

/0 Comments/in , /by

Benign prostatic hyperplasia, or BPH, is a non-cancerous enlargement of the prostate. As the prostate enlarges, its lateral lobes may compress the urethra and obstruct the flow of urine from the bladder.

Common lower urinary tract symptoms include:

  • A weak or interrupted urinary stream
  • Difficulty starting urination
  • Straining to pass urine
  • Urinary frequency and urgency
  • Getting up repeatedly at night
  • Dribbling after urination
  • A feeling that the bladder has not emptied properly

Medication is usually the first treatment offered to men with troublesome symptoms. However, tablets may provide insufficient relief or cause dizziness, tiredness, reduced libido, erectile problems or altered ejaculation.

The UroLift procedure, also called a prostatic urethral lift or PUL, is a minimally invasive surgical therapy, or MIST, that may provide an alternative to long-term medication and conventional prostate surgery.

What is a MIST procedure?

Minimally invasive surgical therapies are designed to improve urinary symptoms with less tissue damage, less bleeding and a shorter recovery than conventional procedures such as TURP or prostate laser surgery.

Different MIST procedures work in different ways. Some use steam or other forms of energy to destroy prostate tissue. Some temporarily remodel the urinary passage. UroLift mechanically moves the obstructing prostate tissue away from the urethra using small permanent implants.

Its principal attractions are:

  • No cutting or removal of prostate tissue
  • No heat, laser or steam
  • Rapid improvement in many patients
  • Usually brief catheterisation, if any
  • Short recovery
  • A low reported risk of new erectile or ejaculatory dysfunction

The trade-off is that symptom improvement is generally more modest than after a tissue-removing operation, permanent implants remain within the prostate, and some patients will eventually require further treatment.

How does Clips work?

The UroLift system uses small implants to hold the enlarged lateral lobes of the prostate away from the urethra.

Each implant consists of:

  • A small capsular tab placed on the outside of the prostate
  • A stainless-steel urethral end-piece
  • A permanent suture connecting the two components

The implant compresses and retracts the obstructing prostate tissue, widening the urinary channel without cutting, burning or removing tissue.

Most patients require several implants. The exact number depends on the length, size and shape of the prostate and the degree of obstruction. These implants remain permanently in position.

Who may benefit from Clips?

UroLift may be considered for men who:

  • Have moderate or severe urinary symptoms caused by BPH
  • Have obtained inadequate relief from medication
  • Cannot tolerate the side effects of BPH medication
  • Prefer not to take daily medication indefinitely
  • Want a less invasive alternative to TURP or laser surgery
  • Place a high priority on preserving forward ejaculation
  • Want a relatively rapid return to normal activities
  • Have prostate anatomy suitable for a prostatic urethral lift
  • Understand the possibility of future retreatment

It is particularly attractive for sexually active men who wish to improve their urinary symptoms while minimising the risk of dry or retrograde ejaculation.

What prostate size is suitable?

Clinical guidelines and manufacturer labelling are not identical.

Current European Association of Urology guidance recommends offering prostatic urethral lift to men interested in preserving ejaculation who have prostates smaller than 70 mL and no obstructing middle lobe.

American Urological Association guidance supports the procedure for selected men with prostates approximately 30–80 mL and without an obstructing middle lobe.

Manufacturer and regulatory indications may extend to prostates as large as 100 mL and may include selected median-lobe anatomy in some jurisdictions. However, treatment outside the populations best supported by clinical guidelines requires careful patient selection and counselling.

Prostate volume alone does not determine suitability. The shape of the prostate, length of the prostatic urethra, bladder-neck anatomy, degree of obstruction and strength of the bladder muscle must also be considered.

What about an obstructing median lobe?

The median lobe is prostate tissue that projects upwards towards the bladder and may act like a ball valve over the bladder outlet.

UroLift can be used to treat selected obstructing median lobes, and the MedLift study reported encouraging outcomes. Nevertheless, major guideline recommendations remain more conservative because the strongest long-term randomised evidence relates mainly to lateral-lobe obstruction.

A large, mobile or unusually shaped median lobe may be better treated with TURP, laser surgery, Rezūm, Aquablation or another procedure capable of removing or reducing the obstructing tissue.

This is an important anatomical caveat to discuss before choosing UroLift.

Assessment before treatment

Not every urinary symptom is caused by BPH. Infection, urethral stricture, bladder weakness, overactive bladder, neurological disease, medication and prostate or bladder cancer may produce similar symptoms.

Assessment may include:

  • Medical history and examination
  • International Prostate Symptom Score
  • Urine testing
  • PSA testing when appropriate
  • Urinary-flow measurement
  • Ultrasound measurement of residual urine
  • Prostate imaging or ultrasound
  • Flexible cystoscopy
  • Urodynamic testing in selected patients

Cystoscopy may be particularly useful because it allows the urologist to assess the lateral lobes, bladder neck, median lobe and length of the obstructing prostate.

Any urinary infection should be treated before the procedure.

Patients taking aspirin, warfarin, clopidogrel, apixaban, rivaroxaban or other blood-thinning medication require an individual plan. Do not stop blood-thinning medication without instructions from your prescribing doctor and urologist.

How is the UroLift procedure performed?

UroLift is usually performed as a day procedure under local anaesthetic with sedation or a short general anaesthetic.

A cystoscope and specialised delivery device are passed through the urethra. No external incision is required.

The urologist:

  1. Examines the urethra, prostate and bladder.
  2. Positions the delivery device within the prostatic urethra.
  3. Moves the obstructing prostate tissue away from the urinary channel.
  4. Deploys an implant to hold the tissue in its new position.
  5. Repeats the process at selected points until an adequate channel has been created.
  6. Inspects the bladder outlet and controls any bleeding.

The procedure commonly takes less than an hour, although this varies with prostate anatomy and the number of implants required.

Because no prostate tissue is removed, there is usually no specimen for laboratory examination.

Will I need a catheter?

Many men can pass urine after the procedure and go home without a catheter. A catheter may nevertheless be required if there is:

  • Significant prostate swelling
  • Inability to pass urine
  • Pre-existing urinary retention
  • A weak bladder muscle
  • Bleeding or clot formation
  • A high residual urine volume

When required, the catheter is usually temporary. Patients with chronic retention or poor bladder function have a greater risk of failing an early trial without a catheter.

What should I expect after UroLift?

Temporary urinary irritation is common during the first few days.

You may experience:

  • Burning or stinging when passing urine
  • Urinary urgency and frequency
  • Pelvic, perineal or penile discomfort
  • Light blood in the urine
  • Bladder spasms
  • A temporarily weaker or more irregular stream
  • Increased night-time urination
  • A feeling of incomplete emptying

These symptoms generally improve over several days, although urinary irritation may occasionally persist for a few weeks.

Some men notice an improved stream soon after treatment. For others, the benefit develops over the following two to six weeks as swelling and irritation settle.

Managing pain and urinary discomfort

Discomfort after UroLift is usually mild to moderate.

Management may include:

Paracetamol

Paracetamol is commonly sufficient for mild discomfort. Take it according to the instructions provided by your doctor or the directions on the packet.

Avoid accidentally taking additional paracetamol contained in cold, influenza or combination pain medicines.

Anti-inflammatory medication

Ibuprofen or another anti-inflammatory medicine may help when medically appropriate. These medicines may not be suitable for patients with kidney impairment, stomach ulcers, certain heart conditions, bleeding disorders, anti-inflammatory-sensitive asthma or anticoagulant medication.

Check with your doctor or pharmacist before taking an anti-inflammatory medicine.

Medication for urinary symptoms

An alpha blocker may be continued temporarily to assist urine flow while swelling settles. Medication for bladder spasm or urinary burning may occasionally be prescribed.

Practical measures

It may help to:

  • Maintain normal hydration without forcing excessive fluids
  • Limit coffee, tea, alcohol, fizzy drinks and energy drinks
  • Avoid constipation
  • Avoid heavy lifting and vigorous exercise for several days
  • Take pain relief before discomfort becomes severe

Severe or worsening pain should be reported rather than simply tolerated.

Possible complications

Most side effects are mild and temporary, but complications can occur.

Common temporary effects

These include:

  • Pain or burning during urination
  • Blood in the urine
  • Urinary urgency
  • Increased frequency
  • Pelvic discomfort
  • Temporary urinary leakage associated with urgency

Urinary retention

Some men cannot pass urine after the procedure and require temporary catheterisation. The risk may be greater in patients with high residual urine volumes, chronic retention, severe obstruction or a weak bladder muscle.

Urinary tract infection

Infection may cause worsening burning, cloudy or offensive urine, fever, chills or feeling generally unwell. Antibiotics may be required.

Bleeding

Light haematuria is common. Significant bleeding, clot retention or the need for further intervention is uncommon but possible.

Implant-related problems

Potential implant complications include:

  • Incorrect placement
  • Implant exposure within the bladder
  • Encrustation or stone formation
  • Migration or loosening
  • Persistent pelvic discomfort
  • The need to remove an implant
  • Difficulty or irritation during later prostate surgery

Implants placed too close to or within the bladder are more likely to develop encrustation and may require endoscopic removal.

Persistent symptoms

UroLift treats obstruction but does not correct every cause of lower urinary tract symptoms. Urgency, frequency and nocturia may persist when they are caused by bladder overactivity, excessive night-time urine production, sleep apnoea, fluid intake, diabetes or other medical conditions.

Need for further treatment

Some patients obtain insufficient relief or develop recurrent symptoms as the prostate continues to enlarge. Further treatment may involve medication, additional implants, removal of exposed implants or another procedure such as TURP, GreenLight laser, HoLEP, Rezūm or Aquablation.

When should I seek urgent help?

Contact your urologist or attend an emergency department if you:

  • Cannot pass urine
  • Develop fever, shaking or chills
  • Feel generally unwell or confused
  • Pass large blood clots
  • Have heavy or persistent bright-red bleeding
  • Develop severe or increasing pelvic pain
  • Cannot keep fluids down
  • Experience pain that is not controlled by the recommended treatment

Does UroLift affect erections or ejaculation?

Preserving sexual function is one of the main reasons patients choose UroLift.

The pivotal L.I.F.T. study reported no new sustained erectile or ejaculatory dysfunction during five years of follow-up. Because the bladder neck, prostate tissue and ejaculatory pathways are not routinely cut or heated, the risk of retrograde ejaculation is substantially lower than with conventional TURP and many tissue-removing procedures.

However, no treatment can guarantee unchanged erections, sensation, orgasm or ejaculation in every patient.

Men who already have erectile or ejaculatory difficulties should not assume that UroLift will correct those problems. It is primarily a treatment for urinary obstruction.

How effective are Clips?

Clinical studies show meaningful average improvement in:

  • Urinary symptom scores
  • Quality of life
  • Peak urinary-flow rate
  • The patient’s perception of urinary function

Symptoms may improve quickly because the urethra is mechanically opened during the procedure.

However, the average improvement in urinary flow and symptoms is generally less than that achieved with TURP or prostate enucleation. UroLift is therefore best understood as a compromise: less invasive treatment and better preservation of ejaculation in exchange for more modest de-obstruction and a greater chance of later retreatment.

How long do Clips last?

The implants are permanent, but the symptom relief is not necessarily lifelong.

The pivotal L.I.F.T. study demonstrated sustained average improvements for five years. The reported surgical retreatment rate was approximately 13.6% over five years, or roughly 2–3% per year.

Retreatment estimates vary among studies and real-world populations. The need for further treatment may be influenced by:

  • Prostate size and anatomy
  • Median-lobe obstruction
  • Implant position
  • Severity of the original obstruction
  • Bladder function
  • Continued prostate growth
  • The definition of retreatment used in a study

Patients should distinguish between an implant remaining in position and the treatment continuing to control symptoms. A permanent implant does not guarantee permanent symptom relief.

MRI considerations

UroLift implants are classified as MR Conditional, meaning MRI can generally be performed under specified scanner conditions. Patients should tell the radiology service that they have UroLift implants and provide the implant information card whenever possible.

The metallic components can create image artefact, particularly during prostate MRI. This may obscure portions of the prostate and reduce the diagnostic quality of an MRI used to investigate suspected prostate cancer.

This caveat is particularly relevant for:

  • Younger men with a long future need for prostate surveillance
  • Patients with an elevated or rising PSA
  • Men already undergoing prostate cancer monitoring
  • Patients likely to require prostate MRI or targeted biopsy

Appropriate prostate cancer assessment should be completed before UroLift when clinically indicated.

Can prostate surgery still be performed later?

Yes. TURP, laser surgery, HoLEP and other BPH procedures can be performed after UroLift.

However, the surgeon must account for the permanent implants. Clips may be encountered during resection or enucleation, may affect instruments or laser fibres, and may require removal. Some surgeons therefore consider later surgery technically more complex than treatment of an implant-free prostate.

UroLift does not close the door to future treatment, but it does leave permanent material that the future surgeon must manage.

Who should not undergo a Clip procedure?

Manufacturer contraindications include:

  • Active urinary tract infection
  • Current visible or gross haematuria
  • Urinary incontinence caused by an incompetent urinary sphincter
  • A urethral condition that prevents safe insertion of the delivery device
  • A prostate larger than the maximum permitted by the applicable product labelling

UroLift may also be unsuitable or less predictable in men with:

  • Severe chronic urinary retention
  • A poorly contracting bladder
  • Very high residual urine volumes
  • Urethral stricture disease
  • Bladder stones
  • Recurrent urinary infections
  • Significant ongoing bleeding
  • A very high bladder neck
  • A large or unfavourably shaped median lobe
  • A very large prostate
  • Suspected or untreated prostate cancer
  • Symptoms primarily caused by overactive bladder rather than obstruction
  • A need for maximal and durable removal of obstructing tissue

Advantages of Clips

Potential advantages include:

  • Minimally invasive day procedure
  • No prostate tissue removed
  • No laser, heat or steam
  • Rapid relief in many patients
  • Short recovery
  • Catheter often avoided
  • Low reported risk of new erectile dysfunction
  • Low reported risk of dry or retrograde ejaculation
  • Future BPH treatments remain possible

Limitations and important caveats

Patients should understand that:

  • Several permanent implants remain inside the prostate
  • Symptom and flow improvements are usually less than after TURP or enucleation
  • Retreatment is more common than after tissue-removing surgery
  • Not all median lobes are suitable
  • UroLift does not prevent continued prostate growth
  • Urgency and nocturia may persist if they have a bladder or medical cause
  • The implants may reduce the quality of future prostate MRI
  • Later prostate surgery remains possible but may be technically more complicated
  • Prostate cancer should be appropriately assessed before treatment
  • UroLift does not provide prostate tissue for laboratory examination

Are Clips the right option for me?

UroLift can be an excellent option for a carefully selected man who wants meaningful improvement in urinary symptoms, a rapid recovery and a low risk of ejaculatory dysfunction.

It may be less suitable for someone with severe obstruction, chronic retention, weak bladder function, unfavourable median-lobe anatomy or a need for the most powerful and durable improvement possible.

The decision should take account of:

  • Prostate size and shape
  • Presence of a median lobe
  • Severity of symptoms and obstruction
  • Bladder strength and residual urine
  • PSA and prostate cancer risk
  • Previous treatment
  • General health and medication
  • Importance of preserving ejaculation
  • Acceptance of permanent implants
  • Willingness to undergo future retreatment

A urological assessment allows UroLift to be compared fairly with medication, iTind, Rezūm, Aquablation, TURP, GreenLight laser, HoLEP and other appropriate options.

A Temporary Stent for Benign Prostatic Enlargement: Temporary Treatment Without a Permanent Implant

/0 Comments/in , /by

Benign prostatic hyperplasia or BPH is a non-cancerous enlargement of the prostate. As the prostate grows, it may compress the urethra and interfere with emptying the bladder.

Typical symptoms include:

  • A weak or interrupted urinary stream
  • Difficulty starting urination
  • Straining to pass urine
  • Urinary frequency or urgency
  • Getting up repeatedly at night
  • Dribbling after urination
  • A feeling that the bladder has not emptied completely

Medication is often the first treatment. However, tablets do not help every patient and may cause dizziness, tiredness, reduced ejaculation, erectile difficulties or reduced libido. The iTind procedure offers selected men a minimally invasive alternative to long-term medication or conventional prostate surgery.

What is iTind / Temporary Stent?

The iTind is a small temporary device made from nitinol, a flexible nickel–titanium alloy with “shape memory.”

It is sometimes called a temporary prostatic stent, although it differs from a traditional stent because it is not intended to remain permanently within the prostate. The device is left in place for only five to seven days and is then removed completely.

While in position, three expanding struts apply controlled pressure to specific areas of the prostate and bladder neck. This remodels the prostatic urethra and creates channels through which urine can flow more easily.

The procedure does not:

  • Permanently implant metal within the prostate
  • Remove prostate tissue
  • Use laser, heat or steam
  • Prevent future prostate treatments if symptoms return

Who may benefit from iTind?

iTind may be considered for men who have bothersome urinary symptoms caused by BPH and who:

  • Have obtained insufficient benefit from medication
  • Have developed side effects from BPH tablets
  • Prefer not to take daily medication indefinitely
  • Want a less invasive alternative to TURP or laser surgery
  • Wish to minimise the risk of ejaculatory or erectile side effects
  • Prefer not to have a permanent prostatic implant
  • Have prostate size and anatomy suitable for the device

The procedure is generally best suited to men with moderate-to-severe symptoms and a prostate measuring approximately 25–75 mL, without a significantly obstructing median lobe.

These measurements are a guide rather than a guarantee of suitability. The shape of the prostate, severity of obstruction and function of the bladder are as important as prostate size.

Assessment before treatment

Urinary symptoms are not always caused by an enlarged prostate. Similar problems can result from infection, urethral narrowing, bladder weakness, an overactive bladder, neurological disease, medication or, less commonly, cancer.

Assessment may therefore include:

  • Medical history and examination
  • International Prostate Symptom Score
  • Urine testing
  • PSA testing when appropriate
  • Urinary-flow measurement
  • Ultrasound measurement of residual urine
  • Prostate ultrasound or other imaging
  • Flexible cystoscopy
  • Urodynamic testing in selected patients

Any urinary infection should be treated before the procedure.

Patients taking aspirin, warfarin, clopidogrel, apixaban, rivaroxaban or other blood-thinning medication require an individual management plan. Do not stop blood thinners without instructions from your prescribing doctor and urologist.

How is the iTind procedure performed?

Insertion

The folded iTind device is passed through the urethra using a small cystoscope. It is positioned in the prostatic urethra immediately below the bladder neck and then released.

The procedure is usually performed as day surgery. Depending on the patient and treatment setting, local anaesthetic, intravenous sedation or a short general anaesthetic may be used.

A soft retrieval string remains attached to the device and passes out through the urethra. It is usually secured to the penis until the device is removed.

Most patients can return home on the same day without a urinary catheter. Occasionally, temporary catheterisation is necessary if the patient is unable to pass urine.

The treatment period

The device remains inside the prostate for five to seven days. Its struts gradually apply pressure to the prostate and bladder neck, creating three longitudinal channels within the urinary passage.

Patients remain at home during this treatment period.

Removal

The device must be removed after five to seven days. It is collapsed into a soft catheter and withdrawn in one piece, usually during a brief outpatient visit.

Local anaesthetic gel is often sufficient, although additional pain relief or sedation may be offered when appropriate. No metal or permanent implant remains inside the prostate after removal.

What should I expect while the device is in place?

The five-to-seven-day treatment period is generally the most uncomfortable part of the process. Common temporary symptoms include:

  • Pelvic or perineal pressure
  • Burning or stinging when passing urine
  • Urinary urgency and frequency
  • Discomfort at the tip of the penis
  • Bladder spasms
  • Light bleeding in the urine
  • Interrupted sleep
  • Awareness of the retrieval string
  • A temporarily weak or irregular urinary stream

These symptoms are usually mild to moderate and commonly improve soon after the device is removed.

Patients should generally avoid heavy lifting, vigorous exercise, cycling and sexual activity while the device and retrieval string are in place. Follow the particular instructions provided by your urologist.

The retrieval string should not be pulled, cut, repositioned or removed by the patient.

How can pain and discomfort be managed?

Pain varies considerably between patients. Some men experience only mild pressure, while others find urinary urgency, bladder spasm or discomfort from the retrieval string more troublesome.

A pain-management plan may include the following measures.

Paracetamol

Paracetamol is usually the first choice for mild-to-moderate discomfort. Take it according to your doctor’s instructions or the directions on the packet.

Check cold, influenza and combination pain medicines carefully, as these may also contain paracetamol. Do not exceed the recommended daily dose.

Patients with significant liver disease or heavy alcohol consumption should discuss paracetamol use with their doctor.

Anti-inflammatory medication

An anti-inflammatory medicine such as ibuprofen may help reduce pain and inflammation when medically appropriate.

These medications may not be suitable for patients with:

  • Kidney impairment
  • Stomach ulcers or gastrointestinal bleeding
  • Heart failure or certain cardiovascular conditions
  • Asthma triggered by anti-inflammatory medication
  • Bleeding disorders
  • Anticoagulant or antiplatelet treatment

Check with your urologist, general practitioner or pharmacist before taking an anti-inflammatory medication.

Medication for bladder irritation

An alpha blocker may occasionally be continued or prescribed temporarily to help urine flow. A bladder-calming medication may be considered if urgency or bladder spasms are particularly troublesome.

These medicines are not necessary for every patient and have their own potential side effects.

Practical measures

It may also help to:

  • Maintain normal hydration without forcing excessive fluids
  • Reduce coffee, tea, cola drinks, alcohol and energy drinks
  • Avoid constipation
  • Wear loose, supportive underwear
  • Avoid heavy lifting and strenuous exercise
  • Take pain relief early rather than waiting until discomfort becomes severe

Strong opioid medication is not usually required. It may worsen constipation and, in susceptible patients, contribute to difficulty emptying the bladder.

Severe or increasing pain is not considered something that should simply be tolerated. Contact the treating practice if the discomfort is not controlled by the recommended measures.

What happens after removal?

Burning, urinary urgency and light bleeding may continue briefly after the device is removed, but these symptoms should progressively improve.

Some patients notice an improvement in their stream soon after removal. For others, improvement develops more gradually over several weeks as irritation settles and the remodelled urinary channels stabilise.

Many patients return to normal daily activities within a few days. Your urologist will advise when you may resume strenuous exercise and sexual activity.

Follow-up may include:

  • Review of urinary symptoms
  • Repeat symptom scoring
  • A urinary-flow test
  • Measurement of residual urine
  • Discussion about continuing or stopping BPH medication

Do not stop established prostate medication unless advised to do so.

Side effects and possible complications

Most side effects are temporary and occur while the device is in place. Reported problems include:

  • Burning during urination
  • Urinary frequency and urgency
  • Pelvic discomfort or pain
  • Blood in the urine
  • Temporary difficulty passing urine
  • Urinary tract infection
  • Bladder spasm
  • Movement or incorrect positioning of the device
  • Temporary catheterisation
  • Failure to obtain sufficient symptom relief

Published studies report different complication rates, but most events have been mild and self-limiting. Temporary haematuria, dysuria, urgency and pelvic discomfort are the most frequently reported problems.

Acute urinary retention, urinary infection or significant bleeding are less common but important complications.

When should I seek urgent medical attention?

Contact your urologist or attend an emergency department if you:

  • Cannot pass urine
  • Develop fever, shaking or chills
  • Feel generally unwell or confused
  • Develop severe or increasing pelvic pain
  • Pass large blood clots
  • Have heavy or persistent bright-red bleeding
  • Cannot keep fluids down
  • Notice that the retrieval string or device has moved
  • Develop pain that is not controlled by the agreed treatment plan

Does iTind affect erections or ejaculation?

One of the principal attractions of iTind is its favourable sexual side-effect profile.

Clinical studies have reported preservation of erectile and ejaculatory function in most treated patients. This contrasts with tissue-removing prostate procedures, which may carry a significant risk of retrograde or absent ejaculation.

Nevertheless, no treatment can guarantee that sexual or ejaculatory function will remain unchanged in every patient.

How effective is iTind?

Studies have demonstrated average improvements in:

  • Urinary symptom scores
  • Quality of life
  • Peak urinary-flow rate
  • The patient’s perception of urinary function

The improvement may be less dramatic than that achieved with a tissue-removing operation such as TURP or laser enucleation. The advantage is that iTind is less invasive, usually requires little recovery time and has a low reported risk of sexual side effects.

It is therefore best viewed as a balance between symptom improvement and treatment invasiveness.

How long does the benefit last?

Although the implant remains in place for only five to seven days, the channels produced within the prostate may remain open for several years.

Prospective studies have demonstrated sustained benefit for more than four years in some appropriately selected patients. This does not mean that iTind is guaranteed to last for four years—or that it will provide lifelong relief.

BPH may continue to progress as a man ages. Some patients will eventually need to restart medication or undergo another procedure. Longer-term evidence for iTind remains more limited than that available for established procedures such as TURP or laser enucleation.

Because nothing is left permanently inside the prostate, iTind does not generally prevent later treatment. Options may include medication, another minimally invasive procedure, TURP, GreenLight laser treatment, HoLEP or another form of prostate surgery.

Who should not undergo iTind?

Contraindications described in the manufacturer’s information include:

  • Active urinary tract infection
  • Acute prostatitis
  • Known prostate cancer
  • Known bladder cancer
  • An artificial urinary sphincter or another implant within the urethra
  • Bladder atonia or a non-contractile bladder
  • Neurogenic bladder dysfunction
  • Urinary obstruction caused by a urethral stricture or something other than BPH

The procedure may also be unsuitable or less predictable in men with:

  • A significantly obstructing median prostatic lobe
  • A prostate outside the best-studied size range
  • Severe chronic urinary retention
  • Very high residual urine volumes
  • Recurrent urinary infections
  • Bladder stones
  • Significant ongoing haematuria
  • Advanced bladder weakness
  • A need for rapid and substantial removal of obstructing tissue
  • Anatomy that prevents safe cystoscopic access

Previous prostate surgery, urethral surgery, nickel sensitivity and blood-thinning medication require individual consideration.

Patients with obstruction causing kidney impairment, repeated retention, recurrent infections, bladder stones or significant bleeding may receive more reliable relief from a definitive tissue-removing procedure.

Advantages of iTind

Potential advantages include:

  • Minimally invasive day procedure
  • No cutting, laser, steam or thermal energy
  • No permanent implant
  • Usually no postoperative catheter
  • Rapid return to ordinary activities
  • Low reported risk of new erectile dysfunction
  • Low reported risk of ejaculatory dysfunction
  • Does not usually compromise future BPH treatment

Limitations of iTind

Potential limitations include:

  • Discomfort during the treatment week
  • A retrieval string for five to seven days
  • A second procedure to remove the device
  • Not suitable for every prostate shape or size
  • Less improvement than some tissue-removing procedures
  • Possibility of persistent or recurrent symptoms
  • Potential need for future medication or surgery
  • Less very-long-term evidence than TURP or laser enucleation

Is iTind the right treatment for me?

iTind is not simply a smaller version of TURP. It offers a different compromise: a less invasive procedure with no permanent implant and a favourable sexual side-effect profile, but generally more modest improvement and less long-term evidence than tissue-removing surgery.

The best treatment depends on:

  • The severity of your symptoms
  • The size and shape of your prostate
  • The amount of urinary obstruction
  • Bladder strength and residual urine
  • Previous treatment
  • General health and medication
  • The importance of preserving ejaculation
  • Your willingness to accept possible future retreatment

A urological assessment is essential to confirm that BPH is responsible for the symptoms and to compare iTind fairly with medication, Rezūm, UroLift, TURP, GreenLight laser, HoLEP and other appropriate treatments.
