Wound infection following vasectomy.

Ninety-four patients undergoing vasectomy as day cases were studied prospectively. An overall infection rate of 32.9% was recorded and, apart from haematoma formation and the nasal carriage of organisms, no factors were found that increased the risk of infection. A preoperative hibiscrub shower did not affect the infection rate, even though it was responsible for a significant reduction in skin flora. This raises the possibility of infection following vasectomy being secondary, not occurring at the time of surgery.
