In the 15 years from 1981, 58 white girls were treated for urethral prolapse. They were grouped into those with partial prolapse (n = 17) and those with circular prolapse (n = 41). Medical treatment was successful in 20 patients with 5 recurrences, 2 of whom ultimately required operation. Lack of response to medical treatment resulted in a further 38 patients undergoing surgery. Four girls had complications: bleeding (n = 1) urethral stenosis (n = 2) and recurrence (n = 1). These complications were treated successfully. Pathological changes in prolapsed urethral mucosa are discussed in this report.
