Testicular outcome following laparoscopic second stage Fowler–Stephens orchidopexy

Abstract

ObjectiveTo assess outcome after laparoscopic second-stage Fowler–Stephens orchidopexy (L2ndFSO). Patients and methodsRetrospective review of 94 children (aged 0.75–16 years, median 2.75 years), who underwent L2ndFSO for 113 intra-abdominal testes between January 2000 and May 2009: 75 unilateral, 19 bilateral (11 synchronous; 8 metachronous). Follow-up (range 3 months–10.9 years, median 2.1 years) was available for 88 children (102 testes: 71 unilateral, 31 bilateral). ResultsTesticular atrophy occurred in 9 out of 102 (8.8%), including 8 out of 71 (11.3%) unilateral and 1 out of 31 (3.2%) bilateral intra-abdominal testes (multivariate analysis: p = 0.59). Testicular ascent ensued in 9 out of 102 (8.8%), comprising four (5.6%) unilateral and five (16.1%) bilateral testicles (multivariate analysis: p = 0.11). Of the 18 bilateral testes brought to the scrotum synchronously none atrophied and four (22.2%) ascended, compared to one (7.7%) atrophy and one (7.7%) ascent among the 13 testes brought to the scrotum on separate occasions (Fisher exact test: p = 0.42 and p = 0.37, respectively). Mobilization of the testis through the conjoint tendon tended towards less ascent (multivariate analysis p = 0.08) but similar atrophy (p = 0.56) compared to mobilization through the deep-ring/inguinal canal. Logistical regression analysis identified no other patient or surgical factors influencing outcome. ConclusionsThis is the largest series of L2ndFSO to date. A successful outcome is recorded in 85 out of 102 (83.3%) testicles. Atrophy occurred in 8.8% and ascent in 8.8%.
