Purpose: To evaluate the risk factors for urinary tract infection (UTI) after retrograde intrarenal surgery (RIRS).
Materials and Methods: A retrospective evaluation of the records of patients who underwent RIRS from January 2013 to September 2016 was performed. All interventions were done by same surgeon and same technique. Pre and postoperative risk factors were noted in IBM SPSS statistics (21.0) data recording system; to determine the risk factors, chi-square tests, binary (multiple) logistic regression analysis were performed, odds ratio and 95% confidence interval were calculated.
Result: 111 patients were included in the study with a mean age 47.5 (14-84). Postoperative infection rate was 12.6% (14 patients). SWL, preoperative double J stent insertion, localization, gender, operation side had no impact on origination of infectious complications (P> 0.005 for all). Preoperative infection history (P =.002, OR=7.96, CI%95: 2.0- 30.5), comorbidity score (P =.008, OR=7.79, CI%95: 1.7- 35.5), and residual fragments were found the significant risk parameters on postoperative infectious complications (P =.045, OR=5.12, CI%95: 1.03 – 25.36).
Conclusion: To reduce UTI complications, it is necessary to pay attention on patients with comorbidities, appropriate antibiotic prophylaxis who had urinary tract infection history and achieve stone free status.
