To assess the role of short-term antibiotic therapy (ABT) in preventing urinary tract infection (UTI) after catheter removal following laparoscopic radical prostatectomy (LRP).


729 consecutive patients underwent LRP by one of two surgeons. One surgeon systematically prescribed a 3-day course of ABT (ciprofloxacin) starting the day before catheter removal; the other surgeon did not. The groups were compared for the incidence of symptomatic UTI occurring within 6 weeks after catheter removal.


ABT was given to 261 of 713 patients (37%), while the remaining 452 patients (63%) did not receive ABT. After catheter removal, UTI was observed less frequently among patients receiving ABT: 3.1 vs. 7.3% in those not receiving ABT (p = 0.019). A number needed to treat to prevent 1 UTI is 24. Hospital readmission for febrile UTI was observed only in patients who did not receive ABT (n = 5, 1.1 vs. 0%, p = 0.16). One would need to prescribe ABT for 91 LRP patients to prevent 1 case of febrile UTI.


ABT at the time of catheter removal reduced the risk of postoperative UTI after LRP. One would need to prescribe ABT to 24 patients to prevent 1 case of UTI.
