We evaluated the results and advantages of laparoscopic examination in 28 patients with 32 nonpalpable testes. Between April 1991 and May 2006, 28 patients, 12 months to 12 years old, with 32 nonpalpable testes underwent diagnostic laparoscopy under general anesthesia before surgical management of the testes. If the blind end of the vas deferens and/or spermatic vessels was observed, the diagnosis of vanishing testis was made, and no further examination or treatment was performed. If intra-abdominal testis was observed, laparoscopic orchiectomy or open orchiopexy was performed. If the internal spermatic vessels and vas deferens entered into the internal inguinal ring, the diagnosis of intra-canalicular testis was made so that the inguinal canal was opened for surgical interventions. Of the 32 nonpalpable testes 10 were on the right side and 22 were on the left side (4 patients had bilateral undescended testes). There were 7 (21.8%) vanishing, 5 (15.6%) intra-abdominal and 20 (62.5%) intra-canalicular testes. There were no complications related to laparoscopy. Laparoscopy can be safely performed to assess the location of the non-palpable testes. Another advantage of the laparoscopic examination is that orchiopexy or orchiectomy can be immediately performed after the examination to avoid a second surgery.
