Rezūm is usually better for a man with a moderately enlarged prostate who wants a less invasive treatment and strongly values ejaculation preservation, while TURP is generally better when faster, stronger and more predictable de-obstruction is needed. Rezūm uses steam and relies on gradual tissue shrinkage; TURP physically removes obstructing prostate tissue with an electrical resection loop. TURP has decades of evidence and usually produces a larger improvement in flow, but it requires anaesthesia, a catheter and a longer recovery and commonly causes retrograde ejaculation. The decision should be based on anatomy and complications, not only convenience.

Quick comparison

What Rezūm means

Rezūm delivers controlled water vapour into obstructing prostate tissue. It is usually a day-care procedure and does not remove tissue immediately. Symptoms can temporarily worsen from swelling before improvement starts. It is attractive when avoiding a major transurethral resection and preserving ejaculation are important.

What TURP means

TURP removes the central obstructing prostate tissue using a resectoscope passed through the urethra. Bipolar TURP is widely used. The operation creates a wide channel immediately but requires anaesthesia, postoperative catheterisation and healing of a larger internal raw surface.

When Rezūm may be preferred

• Moderate symptoms without complications that demand maximal de-obstruction.
• Preservation of ejaculation is a major priority.
• The patient accepts delayed improvement and a temporary catheter.
• Prostate size and anatomy fit water vapour therapy.

When TURP may be preferred

• Recurrent or refractory urinary retention.
• Bladder stones, recurrent infection or upper-tract effects from obstruction.
• Need for rapid and substantial flow improvement.
• The patient accepts the high likelihood of retrograde ejaculation in exchange for a more definitive channel.

Benefits and limitations that matter most

The key difference is intensity. Rezūm aims to reduce obstruction with less procedural burden; TURP deliberately removes more tissue. A man with a high residual urine and repeated retention should not choose Rezūm simply to avoid surgery if a stronger outlet procedure is clinically safer. Conversely, a sexually active man with moderate symptoms and favourable anatomy may reasonably accept the slower response and retreatment uncertainty of Rezūm.

What the guideline evidence changes

TURP remains an established reference operation for appropriately sized obstructing prostates. Rezūm has meaningful randomised and five-year outcome data, but the 2026 EAU guideline still categorises water-vapour therapy among ablative techniques under investigation because direct comparison with established reference surgery remains limited. In the comparative data available, TURP generally gives greater objective improvements in flow and residual urine.

This is why the comparison is not “old surgery versus new technology.” It is a trade-off between a more proven, stronger outlet operation and a less invasive option that usually preserves ejaculation better.

Recovery differences

Rezūm is commonly day-care and heavy activity is restricted for a shorter period, but irritative symptoms can persist while the prostate shrinks. TURP usually involves a short hospital stay, a catheter and several weeks before full heavy activity. TURP patients can have recurrent bleeding as the internal surface heals, whereas Rezūm patients more often notice swelling-related urgency and catheter dependence early.

A practical way to choose between them

A 60-year-old man with a 50 mL prostate, bothersome symptoms, a residual of 60-80 mL, no retention and a strong wish to preserve ejaculation is asking a very different question from a 72-year-old with repeated retention, a residual of 350 mL and a bladder stone. Rezūm can be a reasonable trade-off in the first situation if the anatomy fits. In the second, a tissue-removing operation is usually being chosen for reliability, not convenience.

• Favour Rezūm when symptoms are bothersome but complications are absent, anatomy is suitable and preserving ejaculation matters greatly.
• Favour TURP when rapid, substantial de-obstruction is the priority and the gland is in a conventional TURP size range.
• Repeated retention, bladder stones, recurrent infection or upper-tract effects push the decision toward a stronger outlet operation.
• If the bladder may already be weak, urodynamics can be more important than debating Rezūm versus TURP.

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.
