["Uncomplicated" inguinal testis : How practicable are the guidelines?].

It has been known for more than 20 years that early treatment of maldescended testicles can have a positive effect on fertility and a negative effect on the development of tumors. In certain circumstances, hormone therapy is still recommended in German-speaking countries. However, its benefit is still controversially discussed. Therapy is usually initiated by the pediatrician, who is usually the first to detect undescended testicles. Since therapy may involve early hormone therapy as well as surgery, acceptance among pediatricians and also the parents may be reduced. The question also arises as to how far the implementation is practicable. In patients with nonpalpable testis, there are many controversies concerning the value of ultrasound investigations. In the following two case studies, the treatment decisions for undescended testes in infancy are exemplified. Furthermore, the available evidence from the literature and guidelines is presented to provide assistance for daily routine care and to critically discuss potential fields of application and limitations of existing guidelines.
