Summary
The investigators will determine the efficacy of an innovative short regimen of methenamine hippurate on prevention of post-operative UTI in patients requiring short-term catheterization after pelvic reconstructive surgery through a single-blind, randomized controlled trial. Primary outcome will be the rate of symptomatic UTI within 3 weeks of catheter removal. The investigators will study cost-effectiveness, antibiotic resistance profiles, and adverse drug effects. Findings may reduce antibiotic use and nosocomial UTIs.
