[Interdisciplinary concepts of surgical sex transformation in transsexual patients].

From the introduction of the law on recognition of transsexuals (TSG) in 1980, over 1400 decisions were made by German regional district judges up to 1990. In over 90% of the cases the desired gender was accepted and attested officially. In the near future, a growing number of requests has to be expected. Generally, transsexual patients desire surgery to achieve a complete sex change. Since the foundation of an interdisciplinary gender dysphoria identity committee at our institution in 1989, we have developed criteria on indications, operative techniques and follow-up, which would overtax a urology department, but which can be managed by an interdisciplinary team. Operative techniques may be regarded as well standardized in male-to-female transsexuals and may be performed by the urologist alone; in female-to-male transsexuals sex transformation remains complex interdisciplinary challenge to urologists and plastic surgeons, mainly due to urethral complications. Continuous psychiatric guidance and endocrinological monitoring of the patients facilitates indications for surgery and perioperative management.
