Effect of standard antibiotic prophylaxis versus enhanced prophylactic measures on rate of urinary tract infection after flexible ureteroscopy: A randomized clinical study
Abstract BackgroundPrevention of urinary tract infections (UTIs) after flexible ureteroscopy (fURS) remains controversial. The present study aimed to compare the rate of post-procedural UTI in patients subjected to the standard antibiotic prophylaxis alone versus enhanced prophylactic measures.Methodsfrom August 2018 to September 2020, a total of 100 patients subjected to fURS for management of ureteral and/or renal stones were included in this study. Patients were equally and randomly divided to two treatment groups using randomly computer-generated allocation tables and concealed envelope technique. Treatment groups included standard antibiotic prophylaxis group and enhanced prophylaxis group. Patients in the standard antibiotic prophylaxis group IV, fluoroquinolone 1 hour preoperatively and oral antibiotics were used for 24h postoperatively. In the enhanced prophylaxis group, patients had urine culture 10 days before the procedure. In addition to the antibiotic prophylaxis, hydrophilic-coated ureteral access sheaths were systematically used.ResultsComparison between the baseline and operative characteristics of the studied groups revealed no statistically significant differences. Postoperatively, 8 patients (16.0 %) in the standard prophylaxis group were diagnosed with UTI in comparison to 2 patients (4.0 %) in the enhanced prophylaxis group expressing a statistically significant difference (p = 0.046). Using binary logistic regression analysis, female patients’ sex [OR (95% CI): 0.09 (0.018–0.46), operative time [OR (95%CI): 0.97 (0.94–0.99)] were significant predictors of postoperative UTI in univariate analysis. However, only female sex remained significant in multivariate analysis [OR (95% CI): 0.09 (0.017–0.49)].ConclusionsUrinary tract infection after fURS can be significantly reduced by using the suggested enhanced prophylactic approach.
