Evaluation of the risk factors associated with the development of post-transurethral resection of the prostate persistent bacteriuria

Abstract

Objectives To determine the preoperative, intraoperative and postoperative risk factors that influence the development of persistent post-transurethral resection of the prostate (TURP) urinary tract infection (UTI) defined as pyuria and/or bacteriuria remaining for 3 weeks after surgery. Patients and methods This is a prospective study including 100 patients scheduled for TURP. Urine analysis and culture was performed immediately after catheter removal, then at 1 and 3 weeks postoperatively, and the results were correlated to various preoperative, intraoperative and postoperative potential risk factors to detect any significant relation to persistent UTI. Results There was a statistically significant relationship between bacteriuria and the following risk factors: old age, past history of diabetes mellitus, large prostatic size, positive preoperative urine analysis and culture, preoperative catheter use, previous urological interventions, large size of sheath, long duration of operation, postoperative catheter events and postoperative manual wash. Conclusions Many risk factors have been found to contribute to the development of post-TURP UTI and avoiding these factors can enhance recovery of patients undergoing TURP.
