Laparoscopic treatment of nonpalpable testicle. Factors predictive for diminished size.

PURPOSE: The purposes of this study were to demonstrate the usefulness of laparoscopy in intraabdominal testicle (IAT) and to determine factors associated with diminished size during the final outcome after laparoscopic orchidopexy.

METHODS

This is a retrospective analysis of consecutive patients from 1999 to 2013 with a minimum follow-up of 1year. Patient and testicular factors were related to diminished size.

RESULTS

Sixty one patients, and 92 testicles were included. Median age at operation was 42months. Initially we found 66 normal sized testes (71.7%), 22 hypotrophic (23.9%) and four atrophic (4.3%). Eighty seven testes were brought down laparoscopically, 50 in one surgical stage and 37 in two stages. Mean follow-up was 40.2months and the final outcome was success: 73.5% and diminished size: 26.5%. Variables associated with diminished size were hypotrophy during initial evaluation, short spermatic vessels, section of spermatic vessels, two-stage surgery and tension to reach contralateral inguinal ring. Multivariate analysis showed that initial hypotrophy (odds ratio [OR] 4.96, confidence interval 95% [CI] 1.36-18.10) and tension to reach contralateral ring (OR 4.11, 95% CI 1.18-14.34) were associated with diminished size.

CONCLUSIONS

Laparoscopy is useful in treating IAT. Initial size and tension to reach contralateral ring are factors associated with diminished size.
