Preventing Urinary Tract Infection Post-Surgery
Phase II Efficacy of Cranberry Powder in Preventing Catheter-associated Urinary Tract Infection Post Elective Gynecological Surgery

Approximately 10-27% of patients undergoing gynecologic surgeries develop a catheter associated urinary tract infection (CAUTI) in the post operatory period, as bladder catheterization is a common practice in gynecologic surgery. Cranberry products provide alternative means for preventing CAUTI and could result in decreased use of antimicrobials. In this pilot study we will enroll 200 women post gynecologic surgery and randomize them to take either cranberry capsules or placebo. The low risk of harm associated with using cranberry to reduce UTI coupled with its potential benefit makes it a desirable intervention for the prevention of CAUTI. The conduct/ results of this pilot /feasibility study will prepare us for the conduct of a large scale clinical trial.
