Abstract

PURPOSE: To report our management of preoperative polymicrobial urine culture and to determine its correlation with the risk of postoperative urinary tract infection (UTI).

PATIENTS AND METHODS: We retrospectively identified all patients with preoperative polymicrobial urine culture in our center between January 2017 and October 2019. Preoperative urine cultures were collected 5 to 8 days before the surgery. No antibiotic prophylaxis was administered preoperatively in the absence of pyuria. Patients with pyuria (≥10 leukocytes/mm

RESULTS: In all, 690 patients were included in the study. In line with our protocol, patients had Ceftriaxone, Fluoroquinolones, another antibiotic or no antibiotic prophylaxis in 492 cases (71.3%), 22 cases (3.2%), 31 cases (4.5%), and 145 cases (21%), respectively. The overall sterilization rate of 40.4% was similar between each treatment arm (P=0.54). Postoperative UTI occurred in 68 cases (10.5%). In multivariate analysis, a sterile urine culture the day before surgery was the only factor decreasing the risk of postoperative UTI (OR 0.39, 95%CI, 0.17-0.84; P=0.022).

CONCLUSIONS: Our findings suggest that empirical antibiotic therapy for the treatment of preoperative polymicrobial urine culture is no longer adequate. Further evaluation of organisms isolated may provide the necessary antibiograms for initiation of susceptibility based antibiotic therapy that could decrease postoperative UTI rates.
