HoLEP vs Aquablation vs Rezum vs TURP — which is best for you?

All four are established treatments for benign prostate enlargement. They are not interchangeable. The right choice depends on prostate size, symptom severity, priorities around sexual function, and surgeon experience — not on which procedure sounds most modern.

Many men reach a point where tablets no longer feel sufficient, or where the thought of taking medication indefinitely starts to wear thin. That is usually when procedural options come into view — and the names can sound more confusing than helpful: HoLEP, Aquablation, Rezum, TURP.

All four are established treatments for urinary symptoms caused by benign prostate enlargement, known as BPH. They are not the same, they are not interchangeable, and the "best" one depends less on marketing language and more on your anatomy, symptoms, health, and priorities.

The most important point

A very good operation in experienced hands is often better than a theoretically ideal procedure offered only occasionally. Surgeon volume and centre experience matter as much as the choice of technique — always ask how many of the recommended procedure the team performs each year.

How treatment decisions are usually made

Treatment decisions are based on symptom burden and urinary obstruction — not prostate size alone. A man with a large prostate may cope well on medication, while someone with a smaller gland may have debilitating frequency, poor flow, night-time trips to the toilet, or recurrent retention.

Clinicians look at the whole picture: symptom scores, urine flow measurement, post-void residual, PSA, prostate size and shape, and any complications such as recurrent infections, bladder stones, bleeding, or kidney effects. Your own priorities matter just as much as the clinical picture.

The questions that usually frame the decision are:

  • How severe are the symptoms, and how much are they affecting quality of life?
  • What is the prostate size, and does its shape suit any particular technique?
  • What is the risk of urinary retention if treatment is delayed?
  • How important is preserving ejaculation — and has this been discussed honestly?
  • What are the expectations around recovery time and duration of catheter use?
  • What is the surgeon's experience with each available option?

The four procedures compared

Treatment What it does Best suited to Symptom relief Ejaculation Retreatment risk
Rezum Water vapour (steam) shrinks prostate tissue over weeks Moderate symptoms, selected anatomy, men prioritising lighter recovery Good, not immediate — improvement builds over weeks Often better preserved Higher than HoLEP or TURP
TURP Endoscopic resection of obstructing prostate tissue Small to moderate prostates, reliable surgical standard Strong Retrograde ejaculation common Low
Aquablation Robotically guided waterjet removes tissue without heat Moderate to large prostates, men seeking strong relief and a modern approach Strong May preserve ejaculation better than TURP in selected men — not guaranteed Low — long-term data still growing
HoLEP Laser enucleation removes the obstructing core of the prostate Any prostate size — particularly suited to large glands Very strong — most complete tissue removal Ejaculatory dysfunction common Very low

Each procedure explained

HoLEP
Holmium laser enucleation of the prostate
What it does
Laser removes the obstructing adenoma (the inner core of the prostate) through the urethra. Most complete tissue removal of the four options.
Prostate size
Works across almost all sizes — especially effective for large and very large prostates
Relief
Very strong, durable
Ejaculation
Dry orgasm common
Retreatment
Very low risk
Best for: men who want the most definitive result regardless of ejaculatory effects — and especially those with large prostates, recurrent retention, or bladder stones.
Aquablation
Robotically guided waterjet resection
What it does
High-pressure waterjet guided by real-time imaging and robotic planning removes prostate tissue without heat. Theatre-based surgical procedure.
Prostate size
Moderate to large prostates — increasingly used for larger glands as evidence builds
Relief
Strong
Ejaculation
May be better preserved than TURP
Retreatment
Low
Best for: men who want strong tissue removal with a modern technique and a potentially more favourable ejaculation profile — who understand this is not a guarantee.
Rezum
Water vapour (steam) therapy
What it does
Steam is injected into the prostate tissue. Over weeks, the treated tissue is reabsorbed and the channel opens. Improvement is gradual, not immediate.
Prostate size
Moderate prostates — less suited to very large glands or severe obstruction
Relief
Good — builds over weeks
Ejaculation
Best preserved of the four
Retreatment
Higher than HoLEP or TURP
Best for: men with moderate symptoms and a clear priority to preserve ejaculation, who understand the improvement is not immediate and retreatment may be needed later.
TURP
Transurethral resection of the prostate
What it does
Endoscopic removal of obstructing prostate tissue through the urethra under anaesthetic. The long-established benchmark procedure for BPH.
Prostate size
Small to moderate prostates most commonly — practice varies by centre
Relief
Strong, well established
Ejaculation
Retrograde ejaculation common
Retreatment
Low
Best for: men who want a proven, widely available surgical option with a long track record — and who are comfortable with the ejaculatory trade-off.

The ejaculation conversation — why it needs honesty

Sexual side effects from BPH surgery are often feared more broadly than they are actually experienced in practice — but ejaculation is a different matter. The distinction between erectile function and ejaculatory function needs to be made clearly at every consultation.

Erectile dysfunction after BPH surgery is relatively uncommon and is not a primary risk of most of these procedures. Men are often surprised to find their erections are unchanged.

Ejaculatory dysfunction — specifically retrograde ejaculation, where semen travels back into the bladder at climax rather than forward — is much more common after tissue-removing procedures. This does not affect the sensation of orgasm for most men, but semen is not produced during intercourse. This change should be discussed openly before any procedure is chosen.

  • HoLEP: ejaculatory dysfunction is common — similar to TURP or more
  • TURP: retrograde ejaculation is common — typically affects 65–80% of men
  • Aquablation: may offer a better ejaculation profile than TURP for selected patients, though outcomes vary and this cannot be guaranteed
  • Rezum: best ejaculatory preservation of the four — but not universal

If preserving ejaculation is important to you, say so explicitly at your consultation. It is a legitimate clinical priority and should shape the recommendation.

Matching the procedure to your priorities

Maximum durability and lowest retreatment risk: HoLEP usually leads, with TURP close behind for smaller to moderate prostates. Both offer strong, long-lasting results.
Preserving ejaculation is the primary concern: Rezum offers the best ejaculatory preservation. Aquablation may offer a middle ground — discuss this in detail, including your specific anatomy and what the evidence at your centre shows.
Large prostate with severe obstruction: HoLEP is often the most appropriate choice — it is not limited by gland size in the way that TURP or Rezum can be, and its durability is unmatched for large volume glands.
Moderate symptoms, lighter recovery preferred: Rezum is often appealing here — the procedure is typically shorter, the recovery less demanding, and the ejaculatory profile the best of the four. The trade-off is that improvement is gradual and retreatment more likely long-term.
Strong relief, newer technology, larger prostate: Aquablation is increasingly used in this setting. Evidence for larger prostates is growing, and symptom outcomes are strong. It is not a minor procedure — anaesthetic and theatre are required.
Widest availability and established track record: TURP remains the most accessible surgical option in most UK centres. If you want a proven operation with a long evidence base, TURP is a very sound choice — provided the ejaculatory trade-off has been discussed.

Questions to ask your urologist

A good consultation should make the decision clearer, not more complicated. Arriving with specific questions moves the conversation from generalities to something clinically useful for you.

  1. What is my prostate size, and does its shape rule any option in or out?
  2. Do my symptoms reflect mainly obstruction, bladder overactivity, or both — and does that change the recommendation?
  3. Which of these procedures do you think best fits my anatomy and symptom pattern?
  4. What is the chance of retrograde ejaculation or dry orgasm with each option you're recommending?
  5. How quickly should I expect improvement, and how long is catheter use likely to be?
  6. What is the likelihood of needing another procedure in five or ten years?
  7. How many of the recommended procedure does this centre perform each year?
  8. If my prostate is large, are all four options equally suitable — or are some less likely to give adequate relief?

If answers feel vague, or if only one procedure is recommended without a clear reason specific to your anatomy and priorities, a second opinion is entirely reasonable. That applies especially when the prostate is large, anatomy is unusual, ejaculation is a major concern, or prior retention has occurred.
