Could a simple catheter replace general anesthesia for prostate treatment?
NCT ID NCT06657872
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two methods of pain control during a water vapor therapy (Rezum) for enlarged prostate. One group gets general anesthesia, the other gets local anesthesia injected directly into the prostate using a special catheter. The goal is to see if local anesthesia can shorten time in the operating room and improve recovery. About 24 men aged 45-80 with moderate to severe symptoms will participate.
