Abstract：Objective: To investigate the clinical effect of prophylactic antibiotics in cystoscopic ureteral stent removal. Methods: A total of 78 patients undergoing cystoscopic ureteral stent removal were retrospectively analyzed in this study. Each cohort consisted of 39 subjects: with and without prophylactic antibiotics before stent removal. The primary outcome assessed was development of symptomatic urinary tract infection (UTI) within 4 weeks after stent removal. Results: Two patients in the antimicrobial cohort (5%) developed a UTI and none of the patients who did not receive antimicrobial prophylaxis developed a UTI (P=0.15). The difference was not statistically significant. Conclusions: In our cohort study antimicrobial prophylaxis before cystoscopic stent removal did not appear to provide a significant benefit in UTI prevention. Antimicrobial prophylaxis may be not necessary for cystoscopic stent removal.
