Aquablation and TURP can both provide strong relief from benign prostate obstruction. In men with prostates around 30-80 mL, randomised evidence shows Aquablation can achieve symptom and flow outcomes that are broadly comparable with TURP while preserving antegrade ejaculation more often. TURP is more widely available, has decades of outcome data and gives the surgeon direct resection and haemostasis throughout the operation. Aquablation uses ultrasound planning and a robotic saline waterjet, but bleeding control still requires catheter pressure and/or cautery. For many patients, the decision is less about which operation “works” and more about ejaculation, prostate anatomy, availability and surgeon experience.

Quick comparison

What Aquablation means

Aquablation is planned with transrectal ultrasound and executed by a robotically controlled saline jet. The surgeon defines treatment limits and then performs or supervises haemostasis after ablation. The method can preserve tissue near the ejaculatory ducts more deliberately than a standard circumferential resection in selected cases.

What TURP means

TURP removes tissue under direct cystoscopic vision using monopolar or bipolar electrosurgery. The surgeon cuts chips while coagulating vessels. It remains a benchmark operation for moderate-sized glands and is familiar to most urological centres.

When Aquablation may be preferred

• Preserving ejaculation is important but strong de-obstruction is still required.
• A median lobe or irregular anatomy can be mapped safely.
• Dedicated Aquablation equipment and experienced surgical support are available.
• The patient accepts the need for anaesthesia, catheterisation and bleeding monitoring.

When TURP may be preferred

• Aquablation technology is unavailable or cost is a major barrier.
• A conventional, widely validated operation is preferred.
• The surgeon judges direct resection and haemostasis more appropriate for the anatomy.
• Antegrade ejaculation is not a major priority.

Benefits and limitations that matter most

Aquablation should not be described as bloodless. The waterjet is non-thermal, so a haemostasis strategy is essential. TURP has a higher rate of ejaculatory dysfunction, while Aquablation’s major differentiating benefit is functional preservation rather than a dramatically easier postoperative course. Both still create an internal prostate wound and require recovery.

How mature is the Aquablation evidence?

Aquablation is not in the same evidence category as several newer office-based BPH treatments. The 2026 EAU guideline strongly recommends it as an alternative to TURP for men with moderate-to-severe symptoms and prostates of 30-80 mL, particularly when preserving ejaculation is important. Five-year randomised data support durable outcomes in that range.

Prospective data also extend into 80-150 mL glands, but the guideline still notes that additional randomised evidence is needed for large prostates. Above about 80 mL, the conversation often expands from Aquablation versus TURP to Aquablation versus HoLEP or another enucleation technique.

Recovery differences

Both procedures usually involve a catheter and short hospital observation. Burning, urgency, frequency and blood in the urine are expected during healing. Heavy lifting and strenuous exercise are restricted for several weeks. Aquablation may preserve ejaculation better, but its early bleeding precautions are similar to other tissue-removing operations.

The decision changes with prostate size

In a 60 mL obstructing prostate, both TURP and Aquablation are legitimate tissue-removing choices; ejaculation priority, bleeding strategy, cost and local expertise may decide. In a 120 mL gland, TURP is no longer the obvious benchmark. Aquablation may still be feasible, but HoLEP or another enucleation becomes an important comparator because of established size-independent use.

• For 30-80 mL glands, Aquablation has direct randomised evidence against TURP and can be especially attractive when ejaculation preservation matters.
• TURP remains a highly practical choice when wide availability, lower technology dependence and established resection pathways matter more.
• For 80-150 mL glands, Aquablation has prospective data, but large-gland counselling should include enucleation options.
• A suspected weak bladder, very high residual or catheter dependence may require urodynamic assessment regardless of which tissue-removing operation is chosen.

What to bring for consultation

• Ultrasound with prostate volume and post-void residual.
• Uroflowmetry if available.
• Urine routine/culture and serum creatinine.
• PSA report when clinically relevant.
• Medication list, especially alpha blockers, 5-alpha-reductase inhibitors and blood thinners.
• Records of catheterisation, retention or previous prostate procedures.
