Hernia surgery drug trial halted early – what it means for patients
NCT ID NCT04491526
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether tamsulosin, a drug used for prostate symptoms, could prevent men from having trouble urinating after hernia repair. The trial planned to include 312 men aged 60 and older, but it was stopped early. Because it was terminated, we cannot draw firm conclusions about whether the drug works for this purpose.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tamsulosin
- What this could lead to
- If effective, tamsulosin could reduce the need for catheterization after hernia surgery, making recovery easier for men.
- What could go wrong
- The trial was terminated early, so we don't have clear evidence. Tamsulosin may cause dizziness or low blood pressure in some men.
