Routine contralateral orchiopexy for children with a vanished testis.

AIM: The aim was to determine whether routine contralateral orchiopexy is justified in a child with a vanished testis from intrauterine torsion. METHODS: A retrospective study of thirty-one consecutive boys with a vanished testis who underwent contralateral orchiopexy with the sutureless technique over an eight-year (1995 - 2002 inclusive) period was carried out. Operative findings were analyzed. All patients have been followed to date and interviewed by telephone. RESULTS: Of the thirty-one patients, 22 had testicular abnormalities (71 %). Five patients (16 %) had abnormalities that could predispose them to metachronous torsion. These included bell clapper deformity (3), horizontal lie (1), and ectopic testis (1). Other abnormalities were abnormal epididymal-testicular fusion (2), hydrocele (2), and one testis did not show compensatory hypertrophy. CONCLUSIONS: Sixteen percent of patients had testicular abnormalities that could predispose them to metachronous torsion. There was no morbidity from the operation and no post-orchiopexy torsion on follow-up. Therefore, routine contralateral orchiopexy in a boy with a vanished testis appears to be safe and effective. A large multicenter trial should be done to investigate these preliminary findings. If confirmed, contralateral orchiopexy should be advocated.
