The genital tract in female children with imperforate anus.

A retrospective study was undertaken to determine the type and frequency of genital tract anomalies that occur in female children with imperforate anus. The functional outcome and optimal management of the genital tract anomalies were also studied. Primary vaginal anomalies occurred in 22 of 72 patients assessed, and uterine anomalies occurred in 18 of 51 patients assessed. For 17 patients, who were 13 years of age or older, information was available on genital tract function. Of these 17 patients, five had severe vaginal scarring. A previous vaginoplasty or cloacal abnormality was a predictor of poor vaginal function. It is suggested that vaginoplasty, in cases in which it is possible, be delayed until puberty.
