PURPOSE
Laparoscopic surgery for nonpalpable testes occasionally results in the discovery of the undescended testis in a lower
position than expected. According to our strategy (J Endourol., 2011), in that case, we usually perform laparoscopic
dissection into inguinal canal. In order to evaluate the efficacy of this procedure, we reviewed our surgical outcomes.
MATERIAL AND METHODS
Thirty patients underwent laparoscopic orchiopexy for unilateral intracanalicular testes among 115 patients who
underwent laparoscopic surgery for a nonpalpable testis from September 2009 to August 2014. If the vas and vessels
exited from the internal ring on the side of the nonpalpable testis, the posterior parietal peritoneum was incised and the
gonad was pulled into the abdominal cavity with traction of the whole cord. If a testis was found, laparoscopic
orchiopexy was simultaneously performed. Patients who underwent open trans-inguinal orchiopexy around the same
time were considered the control group for the comparison of surgical outcomes.
RESULTS
Surgical outcomes including the mean operative time were not significantly. The postoperative testicular position was
intrascrotal for all patients in both groups. Among the patients who we could follow up, the testicular size in 16/17
(94.1%) and 15/16 cases (93.8%) were increased in laparoscopic and trans-inguinal orchiopexy group, respectively.
CONCLUSIONS
Even if a testis was located at intracanal, laparoscopic orchiopexy could be performed as safely as for an abdominal
testis, without additional inguinal incisions. We consider the laparoscopic procedure to be feasible for both
intraabdominal and intracanalicular testes when the contra-lateral testis has completely descended into scrotum.
