Routine laparoscopy for nonpalpable testes?

There are still no accepted criteria for the selection of patients with nonpalpable testes for laparoscopy versus a primary surgical exploration. We here report our experience using routine laparoscopy in such patients. The aim was to determine whether laparoscopy should be the first operative intervention or follow an inguinal exploration. Included in the study were 61 boys with 69 nonpalpable testes. Thirty-three testes were found in the abdomen, and 36 testes were extra-abdominal or nonexistent. If an exploration of the inguinal region had been the initial surgical intervention, six testes would have been found, making laparoscopy unnecessary. On the other hand, in the search for 63 missing testes, laparoscopy saved the patients from laparotomy or an extensive inguinal exploration. We conclude that an accurate knowledge of testis, vas, and vessel location gained by laparoscopy facilitates the selection of an appropriate surgical strategy, saving at least 51% of patients from laparotomy or an extensive inguinal exploration.
