Laparoscopic assessment and orchidectomy for the adult undescended testis.

The aim of this study was assessment of the usefulness of laparoscopy in the diagnosis and treatment of the adult nonpalpable testicle. We reviewed retrospectively the case notes of five adult patients with cases of impalpable testis that were evaluated and treated laparoscopically in our institutions. All five patients had unilateral nonpalpable testicles. The mean age of the patients was 36.5 years (+/- 5 years). Laparoscopy defined the intraabdominal anatomy accurately in all cases, and there were no laparoscopic complications. Two testes were found intra-abdominally, another testicle was found lying in the inguinal canal, and the last two testes were absent. Laparoscopy is a safe and reliable method in diagnosing adults with nonpalpable testis and also allows the completion of the operative procedure during a 1-day hospital stay.
