Comparing two treatments for urinary retention in men with prostate issues

A Randomized Controlled Trial Comparing Water Vapour Thermal Therapy (Rezūm) and TURP in Men With Benign Prostatic Hyperplasia in Refractory Urinary Retention

Not applicable Interventional Chinese University of Hong Kong · NCT05762198

This study is testing whether a new treatment using water vapor can help men aged 50-80 with prostate issues and urinary retention just as well as the standard surgery.

What this trial studies

This clinical trial is a randomized controlled trial designed to compare the effectiveness of water vapour thermal therapy (Rezūm) against transurethral resection of the prostate (TURP) in treating men aged 50-80 who experience urinary retention due to benign prostatic hyperplasia (BPH). Participants will be randomly assigned to one of the two treatment arms in a 1:1 ratio. The study aims to determine if Rezūm is as effective as TURP in alleviating urinary retention symptoms. The trial will include men who are currently on a urethral Foley's catheter and have specific prostate size criteria.

Who should consider this trial

Good fit: Ideal candidates for this study are men aged 50-80 with refractory urinary retention related to BPH who are currently using a urethral Foley's catheter.

Not a fit: Patients with a history of prostate cancer or those with conditions that contraindicate TURP or Rezūm will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a less invasive treatment option for men suffering from urinary retention due to BPH.

How similar studies have performed: Other studies have shown promising results with Rezūm therapy, indicating that this approach may be effective, although direct comparisons with TURP are less common.
