Laparoscopic orchiopexy for a nonpalpable testis.

PURPOSE: We evaluated the efficacy and the availability of laparoscopic orchiopexy to manage a nonpalpable intra-abdominal testis and studied outcomes including the testicular survival rate and associated complications.

MATERIALS AND

METHODS

We retrospectively reviewed the medical records of 67 children (86 testicular units) who underwent laparoscopic orchiopexy for a nonpalpable intra-abdominal testis between 1996 and 2008. The mean patient age was 2.4 years (median, 1 year; range, 0.5-9 years), and the mean follow-up period was 21.8 months (range, 0.3-138.4 months). Testicular viability and orchiopexed positioning were evaluated within 1 month and beyond 3 months.

RESULTS

Of 86 testes, 69 testes were treated with primary laparoscopic orchiopexy (PLO) sparing the internal spermatic vessel, 14 testes were treated with one-stage Fowler-Stephens laparoscopic orchiopexy 1, and 3 testes were treated with two-stage Fowler-Stephens laparoscopic orchiopexy 2. The testicular survival rates were 97.7% (84/86) within 1 month and 93.7% (59/63) beyond 3 months. Of 59 viable testes followed up beyond 3 months, 48 (81.4%) testes were positioned in the lower scrotum and 11 (18.6%) testes in the mid to high scrotum.

CONCLUSIONS

Laparoscopic orchiopexy was successful for a nonpalpable intra-abdominal testis with a high testicular survival rate irrespective of the location from the internal ring. However, atrophy of the testis or upward migration of the testis can occur during follow-up, so we suggest watchful, periodic follow-up evaluating the viability and location of orchiopexed testes that are located in the lower scrotum in the immediate postoperative period or during short-term follow-up.
