Simple pill before joint surgery may spare men from catheter
NCT ID NCT03808155
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether taking tamsulosin, a drug used for bladder problems, before hip or knee replacement surgery could prevent urinary retention (inability to pee) afterward. 170 men took either tamsulosin or a placebo for five days before and two days after surgery. The main goal was to see if fewer men in the tamsulosin group needed a catheter within 48 hours after the operation.
