Steam and scans: a sharper way to shrink an enlarged prostate?
NCT ID NCT07663344
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using MRI and AI to guide steam therapy can improve treatment for an enlarged prostate (BPH). Men aged 30-80 with moderate symptoms and a prostate size between 30-80 mL are eligible. All participants receive the standard steam procedure, but with added MRI guidance to plan and deliver the treatment more precisely. The goal is to see if this approach is feasible and leads to better outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- water vapor (steam) thermal therapy
- What this could lead to
- If successful, this approach could make steam therapy for BPH more precise and effective, potentially reducing side effects and improving recovery.
- What could go wrong
- This is a small feasibility study with only 15 participants, so results may not apply broadly. The procedure carries risks like infection, urinary issues, or incomplete symptom relief.
