Prospective evaluation of feminizing genitoplasty using partial urogenital sinus mobilization for congenital adrenal hyperplasia.

Purpose: We present our experience with partial urogenital sinus mobilization in girls with congenital adrenal hyperplasia, with particular attention to vaginal caliber, introitus position, urinary continence and genital appearance.Materials and Methods: We present data on a prospective evaluation of 24 girls with congenital adrenal hyperplasia who underwent feminizing genitoplasty using urogenital sinus mobilization with preservation of the pubourethral ligaments during a 4-year period. Urogenital sinus length determined by cystoscopy and degree of external genitalia virilization, defined according to Prader classification, were evaluated before reconstruction. At followup patients were examined while under sedation for evaluation of overall external genitalia cosmesis and calibration of the vagina. Urinary continence status and voiding efficiency were assessed clinically in toilet trained patients by voiding diary, and measurement of bladder capacity and post-void residual by ultrasound.Results: Patient...
