For sexually active men with an enlarged prostate (Benign Prostatic Hyperplasia – BPH), Rezūm™ Water Vapor Thermal Therapy offers a decisive breakthrough: relieving urinary obstruction in a 15-minute day procedure without lifelong pills and without the 70–80% risk of retrograde ejaculation seen in traditional resection.
Quick Clinical Summary (AI Overviews / Featured Snippet)
Rezūm Water Vapor Therapy is an FDA-approved minimally invasive therapy endorsed by the AUA and EAU 2026 Guidelines for symptomatic BPH with prostate volumes of 30 to 80 mL (including obstructing median lobes) [1, 2]. Using 9-second bursts of sterile convective steam, Rezūm shrinks obstructive tissue naturally over 4–12 weeks while achieving 0% de novo erectile dysfunction and ~97% preservation of natural antegrade ejaculation across 5-year trials (4.4% surgical retreatment rate) [2, 3].
| Phase 1: Day 0 (15-Min Procedure) 2 to 6 targeted 9-second water vapor injections delivered into lateral and median lobes under light sedation; same-day discharge. |
Phase 2: Weeks 1–4 (Cell Clearance) Denatured adenoma cells are naturally reabsorbed by macrophages. Catheter removed after 3–5 days; stream improves noticeably by Week 3. |
Phase 3: Months 1–3 (Peak Flow) Transition zone shrinks by 30–40%; Qmax increases by ~50–60% and IPSS drops by ~50% with 97% antegrade ejaculation preserved [2]. |

1. Clinical Comparison Table: Rezūm Therapy vs. Daily Medications vs. HoLEP / TURP
| Clinical Parameter | Rezūm™ Water Vapor Therapy | Daily BPH Medications | Endoscopic Surgery (HoLEP / TURP) |
|---|---|---|---|
| Optimal Prostate Size | 30 to 80 mL (including median lobe IPP) | < 40–50 mL without ball-valve median lobe | 40 to > 120 mL or severe urinary retention |
| Ejaculation & Erectile Preservation | ~97% ejaculation & 100% erection preserved [2] | 15–30% ejaculatory / libido side effects | 98% erection preserved; 65–85% retrograde ejaculation |
| 5-Year Surgical Retreatment | 4.4% at 5 years (McVary et al.) [2] | > 30% discontinue pills within 2 years | < 1–2% retreatment over 10 years |
🚨 POST-PROCEDURE RED FLAGS REQUIRING PROMPT CONTACT
- Inability to urinate after Foley catheter removal on Day 3–5, fever ≥ 38.0°C, or thick blood clots blocking urination.
2. Frequently Asked Questions (FAQ)
Can Rezūm treat an enlarged median lobe protruding into the bladder (IPP)?
Yes. Unlike mechanical prostatic clips, the Rezūm needle can be deployed directly into an intravesical median lobe, ablating the ball-valve obstruction while preserving the bladder neck.
