Pattern of bacterial flora in local genital skin and surgical wounds in children undergoing hypospadias repair: a preliminary study.

To evaluate the pattern of bacterial flora in children undergoing hypospadias repair, the following swabs were sent for 60 consecutive subjects: perimeatal swabs at admission and immediately before surgical scrub, and intraoperative and postoperative wound swabs (after the first change of operative dressing). A pure or predominant growth of organism that was not part of the local flora was labelled 'infection'. The peak incidence of infection (53%) was detected in swabs taken at admission. This decreased to 30% in immediately preoperative skin swabs, following local preparations. Coliforms and Staphylococcus aureus were the most commonly grown pathogens and were sensitive to cephalosporin and aminoglycoside. Proximity to the anus, poor personal hygiene in our study subjects (who were of low socioeconomic status) and the high temperature and humidity in our geographic region probably led to the high incidence of infection. The authors feel that the results of preoperative perimeatal swabs could help dictate antibiotic therapy in patients awaiting hypospadias repair.
