Preoperative Laparoscopy in the Management of the Nonpalpable Testis
Lojanapiwat B Mail, Soonthompun S , Wudhikam S

The purpose of laparoscopy in the management of the nonpalpable testis is to provide
information regarding testicular presence and location to facilitate overall surgical management.
Laparoscopy was performed at operation in 20 patients between 14 months to 21 years old
(average 63 months), who had 22 nonpalpable testes. Of the testes 13 (59 per cent) were in the
inguinal region or just proximal to the inguinal ring, 8 (36 per cent) were in a high intra-abdominal
position and 1 (5 per cent) were absent. Anatomical localization of nonpalpable testes facilitated
accurate planning of operative repair and the laparoscopy rendered exploration unnecessary in
patients with intraabdominal vanishing testes syndrome, and laparoscopic orchiectomy is the
treatment for the unilateral intraabdominal testes in patients more than 10 years old.
