Steam therapy for enlarged prostate: a new hope?
NCT ID NCT05201131
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This trial is testing a procedure called Rezūm, which uses steam to shrink excess prostate tissue in men with benign prostatic hyperplasia (BPH), a common cause of urinary problems. About 50 men will receive the treatment, and researchers will track changes in urine flow, residual urine, prostate size, and symptom scores over time. The goal is to see if this minimally invasive approach safely improves urinary symptoms in a Canadian population.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Rezūm system (convective thermal therapy using water vapor)
- What this could lead to
- If successful, this could provide a minimally invasive option to relieve BPH symptoms and improve urine flow, potentially reducing the need for more invasive surgery.
- What could go wrong
- This is a small, non-randomized study, so results may not apply broadly. Possible risks include temporary urinary discomfort, bleeding, or infection, and the therapy may not work for everyone.
