[Individualized treatment of undescended testis]

Undescended testis is one of the most common congenital anomalies requiring surgery. The guideline for the treatment of undescended testis was published by Japanese Society of Pediatric Urology in 2005. However, the management of undescended testis has been still controversial, particularly in case of impalpable testis including abdominal testis. In this article, we review our experience and published reports of orchiopexy for undescended testis and emphasize that the anatomical condition of undescended testis should be applied to individualized surgical treatment.
