Abstract
BACKGROUND/ PURPOSE: A normal testis in the scrotum is the most important outcome of the attempted pediatric orchidopexy for a true undescended testis. The reports of post-orchidopexy testicular atrophy in the literature have ranged from non-existent to unclear. Our purpose in this study was to estimate the incidence of and associated risk factors for post-orchidopexy testicular atrophy. METHODS: We performed a retrospective review of data from children who had an attempted orchidopexy for a true undescended testis from 1969 to 2003 inclusive. REB approval 1000011987. RESULTS: There were 1400 attempted orchidopexies involving common (low) type (n=1135), ectopic type (n=174), and high type testes (n=91). There were a total of 111/1400 (8%) atrophic testes, mostly right-sided. 66/111 (59%) were MADE atrophic, and 45 (41%) were FOUND atrophic. Of the 1135 common type, 56 (5%) were MADE atrophic. In the ectopic and high types, the incidence of post-operative testicular atrophy was 1% and 9%, respectively. The most significant risk factors associated with testes MADE atrophic were high testicle, vas problems, and pre-operative torsion. CONCLUSIONS: In this series, the incidence of post-operative testicular atrophy that was MADE was 5% in the common (low) type and 9% in the high type. These numbers and the above risk factors should be quoted to the caregiver during pre-operative informed consent.
