title: Routine contralateral orchiopexy for children with a vanished testis.
abstract: OBJECTIVE
  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.
