Which prostate operation should I have?

The trade, in one sentence

The operations that preserve ejaculation remove less tissue and are more likely to need repeating. The operations that last usually mean a dry orgasm.

Almost everything else is detail. A Cochrane network meta-analysis of the minimally invasive treatments found they deliver similar or worse symptom relief and quality of life than TURP, with fewer major adverse events.¹² A 2023 European systematic review reached the same conclusion: comparable symptom improvement, but the standard operations remain the reference for durability.³

That is not an argument against the newer options. It is an argument for knowing which side of the trade you are buying.

What actually decides your options

Four things, and only one of them is preference.

Prostate size

Below roughly 30–80mL almost everything is on the table. Above 80mL the field narrows; above 150mL it narrows sharply. Enucleation — HoLEP and its thulium equivalents — is the option whose effectiveness is independent of gland size, which is why it dominates the large-prostate literature.⁴ Aquablation has now been studied up to 150mL and beyond with sustained results.⁵

Shape, and the middle lobe in particular

This is the detail that most often invalidates a plan a man has already made. A prostate with a prominent median lobe — a third lobe projecting up into the bladder — is a poor candidate for the prostatic urethral lift, because the implants pull apart lobes that sit either side of the urethra and cannot address one sitting above it.

You cannot know this without imaging or cystoscopy. If someone has recommended a specific branded procedure before looking, they have recommended a procedure, not a plan.

Whether you are in retention

A man managing with a catheter is in a different decision from a man who is merely bothered. Retention shifts the balance towards definitive tissue removal — though not absolutely, and water vapour therapy has been studied specifically in catheter-dependent men with encouraging results.⁶⁷

What you are actually optimising for

Being dry, or being able to ejaculate, or never doing this again. These pull in different directions and you should say out loud which one matters most, because your surgeon cannot infer it.

The surgeon matters as much as the procedure

This is the part the brochures omit.

Enucleation in particular is technique-dependent. A prospective series from a single very high-volume surgeon found that complications and sequelae still occur after the learning curve is complete — an honest finding from a centre with every reason to publish a flattering one.⁸ For Aquablation, a 300-case series found composite success rising from 58% in the first fifty cases to 82% after a hundred and fifty.⁹

So "how many of these do you do a year?" is not a rude question. It is the most useful one you can ask, and it discriminates between providers more sharply than the choice of device does.

What each option is actually for

• TURP — the long-standing reference. Effective, widely available, and the benchmark every trial is measured against. Retrograde ejaculation is likely.
• HoLEP (and thulium enucleation) — removes the most tissue, works at any gland size, and has the lowest retreatment rate of the group. Retrograde ejaculation in most men, and a period of stress leakage in a minority.
• Aquablation — a robotically executed waterjet planned on live ultrasound, with markedly better ejaculatory preservation than TURP. Bleeding is the principal perioperative concern.¹⁰
• Rezūm (water vapour) — day-case, ejaculation usually preserved, but symptoms often worsen before they improve and the benefit builds over one to three months.
• UroLift (prostatic urethral lift) — implants that hold the lobes apart. Fast recovery, ejaculation usually preserved, no tissue removed — and the highest retreatment rate of the mainstream options.
• iTIND — a temporary device that reshapes the bladder neck and is then removed. The smallest evidence base of the group.

The question almost nobody asks, and should

If this fails in five years, does it make the next operation harder?

This matters more as the minimally invasive options are used earlier. Implants that sit in the urethra may need to be dealt with at any subsequent operation; tissue that has been scarred by heat is not identical to virgin tissue at enucleation. The honest position is that sequential procedures are common and mostly manageable, but "we can always do something bigger later" is a claim that deserves a specific answer for the specific device being proposed, not a reassuring generality.

Bottom line

Ask for your prostate volume and whether you have a median lobe, before you discuss brands. Say which of dryness, ejaculation and durability you care about most. Ask how many the surgeon does a year, and what plan B looks like.

If a consultation does not produce those four answers, you have not yet had the consultation.
