Abstract

Objective: To improve the results of feminization plastic surgeries in girls with a disorder of sexual development. Materials and methods: A procedure was proposed for dissociative feminization plastic surgery, which was used in 2018 to 2019 to operate on four girls in the chronological and clinico-hormonal therapy-induced puberty period with virilization of the external genitalia, a high urethrovaginal confluence (UVC), and a long genitourinary common channel (GUCC). Results: Based on the partial urogenital mobilization described by R.C. Rink in 2006, the authors developed a new procedure of feminization plastic surgery for puberty patients with a high UVC and a long GUCC. The procedure is characterized by the preparation of a mucosal flap of the GUCC, by laying it in a W-shaped way to create the anterior and lateral walls of the artificial vaginal orifice (AVO) and preparing the posterior wall of the vagina to create the posterior wall of the AVO. The calculation of the minimum GUCC length, which is required for successful surgery, is presented. Good results were obtained in all the patients. Conclusion: The proposed procedure makes it possible to form the female external genitalia with the separately opening urethra and vagina, with the moist mucous orifice, with the possibility of adequate sexual life in the future, without the risk of vaginal stenosis and urinary disorders.
