Single-stage feminization genitoplasty

Abstract

We present a modified technique for feminization genitoplasty, which combines the main features of the Hendren and Crawford pull-through operation and the Kogan reduction clitoroplasty. The unique features of the operation are the use of a flap of preputial skin to construct the vestibule and the anterior vaginal wall, and the universal use of the urogenital sinus to form the distal urethra, which avoids creation of female hypospadias. The new introitus is ample and, because there is no cut-back of the urogenital sinus, we avoid accidental incision of the urethral sphincter and the potential for urinary incontinence. There is no pull-through of the vagina because the introitus is created by mobilization of anterior and posterior skin flaps. The clitoris and the neourethra are exteriorized through the folded preputial skin, which simulates the normal female anatomy. The cosmetic and functional results in 9 children who have undergone this procedure have been excellent.
