[Study participation in urological specialty practices].

In the past, participation of practicing urologists in clinical trials has been very rare. The reasons for this have been influenced in different ways over the last 10 years, so that the situation has now changed. In this paper, the current motivation for the participation of practicing urologists in research studies is discussed. Moreover, we discuss the ways in which the Association of Urological Oncology (AUO) of the German Cancer Association promotes the participation of colleagues in AUO studies and how the AUO meets the needs of urologists in practice.
