Flomax may prevent Post-Surgery urinary woes in older men
NCT ID NCT06257576
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether tamsulosin (Flomax) can reduce the risk of urinary retention and catheter-related infections in men aged 50 and older after elective surgery. Participants received either tamsulosin or a placebo after their catheter was removed. The goal was to see if the drug helps them urinate normally and avoid complications.
