Abstract
Laparoscopy was performed on 107 patients 8 months to 18.5 years old (mean age 46.9 months) with 119 nonpalpable testes. The procedure accurately determined the location of the gonad in 95.3% of the patients, while 16 were spared formal surgical exploration with the laparoscopic visualization of blind-ending spermatic vessels and vasa deferentia. Additionally, patency of the internal inguinal ring, determined laparoscopically, was an accurate predictor of testicular salvageability. We advocate the use of laparoscopy for all boys with a nonpalpable gonad in conjunction with operative intervention if necessary.
