Incidence and risk factors of bacteriuria after transurethral resection of the prostate

A Colau et al. Eur Urol. 2001 Mar.

Abstract

Introduction: Postoperative bacteriuria is a frequent event after transurethral resection of the prostate, despite the use of prophylactic antibiotics. Certain risk factors have been clearly established (preoperative urinary catheter or bacteriuria, operating time), while others remain uncertain.

Materials and methods: We conducted a prospective study in five urology centers, including non-catheterized patients with sterile preoperative urine undergoing transurethral resection of the prostate for benign prostatic hyperplasia. All received antibiotic prophylaxis with cefamandole. The incidence of bacteriuria and its risk factors were investigated.

Results: The postoperative bacteriuria rate was 26% (26/101), with 8% on removal of the catheter, 14% between the 7th and 10th postoperative days and 5% 1 month postoperatively. Factors associated with bacteriuria on univariate analysis were: operating time, disconnection of the closed urine drainage system and postoperative catheterization > or =3 days. Two variables were associated on multivariate analysis (logistic regression): operating time >52 min (odds ratio 9.0, 95% confidence interval 2.1-39.0) and disconnection of the closed urine drainage system (odds ratio 26.3, 95% confidence interval 6.1; 6.1-113).

Conclusions: The postoperative bacteriuria rate after transurethral resection of the prostate was high in this study, raising the question of the choice and/or duration of prophylactic antibiotics. Prevention of postoperative bacteriuria must be based on careful hemostasis, prevention of postoperative catheter disconnections, and limitation of the duration of postoperative catheterization.
