Use of laparoscopy for the localization of impalpable testes.

Laparoscopy is a simple, safe and sure diagnostic method in order to visualize an abdominal testis. When there is no abdominal testis at laparoscopy, the vas deferens and the testicular vessels have to be looked for very carefully. When both these structures pass through the internal inguinal ring, operation can be limited to the inguinal region. The results of laparoscopy are reported in nine patients with impalpable testis.
