Botox shot into bladder during prostate surgery may ease urgent bathroom trips
NCT ID NCT05878951
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether injecting Botox into the bladder wall during a standard prostate surgery (HoLEP) can better control overactive bladder symptoms like sudden urges to urinate and leakage. About 66 men aged 18-89 with these symptoms will be randomly assigned to get Botox or a placebo during surgery. Researchers will track symptom improvement and side effects for several months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Botox (onabotulinumtoxinA)
- What this could lead to
- If it works, this could offer a way to reduce urgent, frequent urination and leakage in men already undergoing prostate surgery, improving their quality of life.
- What could go wrong
- This is a small, early-to-mid-stage trial, so results may not apply to all men. Risks include temporary urinary retention, bleeding, or infection after the procedure.
