Background/purpose: The aim of this study was to retrospectively review the findings at orchidopexy in acquired undescended testis (UDT).
Methods: The authors reviewed a 14-year (1986 through 1999) surgical experience in 360 boys in whom 461 orchidopexies were performed for acquired-UDT. The operative notes were reviewed to determine at operation testis position and volume, persistence of patent processus vaginalis (PV), and attachment of the gubernaculum. Also, testis position after orchidopexy was evaluated.
Results: Age at operation ranged from 2 to 19 years (mean, 8.9 years), 205 of the 461 orchidopexies (44.5%) had been performed between 9 and 12 years of age. In 327 of the 461 cases (70.9%), testis position was documented as intraoperative; in 281 of these cases (86.0%), the testis was located in the superficial inguinal pouch (SIP). A note was made regarding the presence or absence of a hernial sac in 207 of the cases: 113 (54.6%) were associated with an open PV, which usually was slightly open. In 122 of the 461 cases (26.5%), the gubernacular attachment was assessed; in 121 of these (99.2%), a normal attachment of the gubernaculum was noted. At the end of orchidopexy, in 438 of the 461 cases (95.0%), testis position was recorded. Three hundred eighty-two of these testes (87.2%) were at the bottom of the scrotum.
Conclusions: Acquired UDT usually is characterized by SIP position, closed or (small) open PV, and normal gubernaculum attachment. The results of surgery seem excellent.
