Will I leak after prostate surgery?

The two different problems

Stress leakage — a few drops on coughing, sneezing, lifting or standing up. This is the one associated with enucleation, it is usually early, and it usually settles.

Urgency leakage — the sudden, unarguable need to go, with occasional failure to get there. This one often pre-dates the operation. A bladder that has been pushing against an obstruction for years becomes overactive, and removing the obstruction does not immediately un-train it.

Men frequently attribute the second to the surgery when it was present beforehand and simply less noticeable behind a poor stream. A meta-analysis of incontinence after the various enucleation procedures found mixed incontinence — both types together — was more common after enucleation, and that most cases across all transurethral interventions were transient.¹²

What the numbers look like

Incidence after enucleation is broadly similar whichever laser or energy source is used; what differs is who gets it. A meta-analysis identified age, prostate size, the specific procedure and the laser time as the factors associated with post-operative incontinence.¹ In other words, a larger gland and a longer operation carry more of it — which is worth knowing if you are being offered enucleation for a very large prostate.

Long-term incontinence after TURP is uncommon. After HoLEP, early stress leakage is discussed more openly in patient communities than in most brochures, and the honest framing is that a minority of men use pads for some weeks, a smaller number for some months, and a small proportion have a persistent problem.

For Aquablation, an individual-patient-data meta-analysis found bladder function improved and incontinence symptoms fell overall.³ For iTIND, continence and sexual function preservation are the explicit design goals and the reported rates reflect that.⁴

The technique that changes it

There is now randomised evidence that the ejaculation-preserving variant of HoLEP — which spares tissue near the bladder neck — improves early continence recovery as well as preserving ejaculation.⁵

That is a genuinely useful finding, because it means the two things men most want protected may be protected by the same modification. It is not offered everywhere and it is a reasonable thing to ask about by name.

What actually helps afterwards

Pelvic floor exercises, done properly, are the mainstay — and "properly" is doing a lot of work in that sentence. The Cochrane review of conservative treatments after prostate surgery concluded that their value remains uncertain because the trials are limited and methodologically flawed.⁶

I would not read that as "they do not work". I would read it as: taught, supervised pelvic floor training by someone who checks you are contracting the right muscle is worth arranging, and a leaflet of random Kegels is not the same intervention.

Two other things matter and are rarely mentioned. Caffeine and alcohol both worsen urgency, and cutting them for the recovery period is more effective than most men expect. And bladder retraining — deliberately, gradually extending the interval between visits — treats the urgency component that surgery does not.

When to stop waiting

Most stress leakage after enucleation improves over weeks to a few months. If you are still meaningfully wet at six months, that is the point to stop being told to be patient and to be reassessed properly — with a pad test, a flow study and, where indicated, urodynamics to separate a sphincter problem from a bladder problem.

They have different treatments, and treating the wrong one is the commonest reason a man is still leaking two years later.

What to ask before the operation

1. Given my prostate size and age, what is your own rate of stress leakage at six weeks and six months?
2. Do you offer a bladder-neck-sparing technique, and would it suit me?
3. Will I be referred for supervised pelvic floor training, and when — before or after?
4. If I am still leaking at six months, what happens then?

That last one is the question that gets skipped, and it is the one that determines whether a manageable problem becomes a permanent one.

Bottom line

Permanent incontinence after surgery for an enlarged prostate is uncommon. Temporary stress leakage after enucleation is not, and the men most likely to get it are older, with bigger glands and longer operations.

Urgency is a separate problem, often pre-existing, and it needs bladder retraining rather than patience. Six months is the point at which persistent leakage stops being expected and starts needing a plan.

Worth reading alongside: why am I worse before I am better?, and which operation should I have?.
