Laparoscopic orchidopexy: a review of a large clinical series.
OBJECTIVE
To report the overall success rate of a laparoscopic orchidopexy (LO) series over 5 years including over 100 procedures.


METHODS
The records were reviewed of children who underwent laparoscopic procedures for an impalpable testis at our institutions. The laparoscopic procedures included the standard LO and one-stage and staged Fowler-Stephens (F-S) LOs. The success of orchidopexy was defined as a testis in the scrotum with no atrophy after surgery.


RESULTS
From 1994, 80 children (101 impalpable testes) were treated using LO. Of these patients, 20 (25%) had impalpable testes on the right, 39 (50%) were on the left and 21 (25%) were bilateral. The testicular location was identified during laparoscopy as: intra-abdominal in 46, iliac in 14, in the internal ring in 22, 'peeping' in 12, behind the bladder in three and intracanulicular in four. Standard LO was used in 72 testes, a one-stage F-S in 20 and a two-stage F-S in nine (first stage two, second stage seven). The median (range) age of the patients was 18 months (0.5-12 years); the mean (range) follow-up was 5 (1-36) months. After orchidopexy the testis was scrotal in 90 (low 78, mid four and high eight), at the pubis in one and not stated in seven (no follow-up available). Four patients (4%) had testicular atrophy from failed F-S orchidopexies, two of whom had undergone previous testicular surgery and one caused by additional dissection around the vas. The overall success rate, including only those with follow-up, was 96% (90 of 94). Of the 20 one-stage F-S orchidopexies, 17 testes were successfully placed in the scrotum with no atrophy. The overall success rate for all F-S procedures was 85% (23 of 27). However, excluding patients who had previous testicular surgery or who required extensive dissection near the vas, 96% (23 of 24) of the testes were successfully placed into the scrotum with no atrophy.


CONCLUSIONS
The high overall success rate in placing the testis into the scrotum through laparoscopic procedures is considerably better than reported in other series to date. LO is an effective method for managing intra-abdominal testes in children. Patients who had undergone previous surgery had a higher risk of developing testicular atrophy. The additional dissection around the vas almost inevitably leads to testicular atrophy.
