[A questionnaire survey on the theory of postoperative infection prophylaxis in urologic surgery]

The implementation of the Japanese guidelines for prevention of postoperative infection in urological surgery, based on the Centers for Disease Control and Prevention (CDC) was surveyed. In October 2006, questionnaires about selection of prophylactic antibiotics, timing and period of administration, were distributed to 25 urologists. Surgical procedures were classified into four categories by contamination levels: 1. clean surgery, 2. clean-contaminated surgery, 3. contaminated surgery (surgery with urinary tract diversion using the intestine), and 4. laparoscopic surgery. Implementation of recommendations was about 70% in the selection of prophylactic antibiotics, and 20-30% for the timing of administration in four categories. Adequate implementation was low for the timing of administration. Period of administration in contaminated surgery was longest in all categories. Concerning the administration period and the selection of antibiotics for contaminated surgery, marked differences from recommendations were seen. Therefore further education in hospitals in Japan is needed.
