Effect of Vulvar Re-Antisepsis Before Cystoscopy on Urinary Infections in Laparoscopic Hysterectomy

This prospective observational study aims to evaluate whether additional vulvar re-antisepsis before intraoperative cystoscopy reduces the incidence of postoperative urinary tract infections (UTIs) in patients undergoing total laparoscopic hysterectomy for benign indications. In our institution, cystoscopy is routinely performed at the end of laparoscopic hysterectomy using carbon dioxide (CO₂) as the distension medium to assess bladder integrity and ureteral jet flow. However, potential contamination from the vaginal flora during cystoscopy may increase the risk of postoperative UTI. The study will compare two groups of patients: those receiving standard preoperative antisepsis only and those undergoing additional vulvar re-antisepsis immediately before cystoscopy. The primary outcome is the incidence of postoperative UTI diagnosed according to CDC criteria. Secondary outcomes include cystoscopy duration, catheterization time, and need for postoperative antibiotic therapy. Findings from this study may help determine whether an additional antisepsis step can improve infection control during laparoscopic hysterectomy.
