From the introduction of the law on recognition of transsexuals (TSG)
in 1980, over 1400 decisions were made by German regional district jud
ges up to 1990. In over 90% of the cases the desired gender was accept
ed and attested officially. In the near future, a growing number of re
quests has to be expected. Generally, transsexual patients desire surg
ery to achieve a complete sex change. Since the foundation of an inter
disciplinary 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 ca
n 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 se
x transformation remains complex interdisciplinary challenge to urolog
ists and plastic surgeons, mainly due to urethral complications. Conti
nuous psychiatric guidance and endocrinological monitoring of the pati
ents facilitates indications for surgery and perioperative management.
