Two-step orchiopexy with pelviscopic clip ligation of the spermatic vessels
1Department of Surgery, University of Michigan, Ann Arbor.
Abstract:
Ten boys with nonpalpable testes located in the peritoneal cavity underwent celiopelviscopy and clip ligation of the spermatic vessels with the intent of augmenting vasal collateral blood flow. After intervals in excess of 6 months, 7 patients underwent vas-based orchiopexy following division of the occluded spermatic vessels. Six boys had good results as judged by size of the relocated testes. In 1 boy the testis atrophied. He had undergone previous inguinal-only exploration before referral to us for celiopelviscopy and at stage 2 orchiopexy a silk suture was found on the vas deferens.
