[A multi-center prospective study for antibiotic prophylaxis to prevent perioperative infections in urologic surgery].

In order to assess the ability of our protocol for antibiotic prophylaxis to prevent perioperative infections in urologic surgery, 1,353 operations of open and laparoscopic urologic surgery conducted in 21 hospitals between September 2002 and August 2003 were subjected to analyses. We classified surgical procedures into four categories by invasiveness and contamination levels: Category A; clean less invasive surgery, Category B; clean invasive or clean-contaminated surgery, Category C; surgery with urinary tract diversion using the intestine. Prophylactic antibiotics were administrated intravenously according to our protocol, such as Category A; first or second generation cephems or penicillins on the operative day only, Category B; first and second generation cephems or penicillins for 3 days, and Category C; first, second or third generation cephems or penicillins for 4 days.
