Impact of Tamsulosin on Post-Operative Urinary Retention Following Pelvic Reconstructive Surgery

This trial tests whether tamsulosin — a medication normally used in men with prostate issues to relax bladder outlet muscles — can help women who cannot urinate after pelvic reconstructive surgery. Post-operative urinary retention (inability to pass urine) affects many women after pelvic floor procedures and often requires them to go home with a catheter. Tamsulosin works by relaxing the muscles in the bladder outlet, and this study tests whether it helps women regain normal urination faster after surgery. You may be eligible if: - You are 18 years old or older - You have had pelvic reconstructive surgery and cannot urinate adequately before hospital discharge (failed retrograde void trial) - You can swallow pills and understand English You may NOT be eligible if: - You have an allergy to tamsulosin or sulfa drugs - You had difficulty urinating before surgery (post-void residual over 150 mL) - You already take an alpha-blocker medication for high blood pressure - You have severe dementia, end-stage kidney or liver disease, or recent major cardiovascular event (within 6 months) Talk to your gynecologist or urogynecologist if you experienced urinary retention after pelvic floor surgery and want to know whether a short course of medication might help you avoid prolonged catheter use.
