title: A modified extravesical technique for megaureter repair.
abstract: OBJECTIVE
  To report on the use of extravesical detrusorraphy for megaureter repair.
  
  
  METHODS
  Twenty-three children underwent an extravesical megaureter repair over a 25 month period. There were 17 boys and 6 girls with an average age of 4.4 years. Three children had bilateral megaureters for a total of 26 repairs. Ureters were defined as megaureters if the ureteric diameter exceeded 1.0 cm on pre-operative imaging. There were 14 obstructing and 12 refluxing ureters. Three of the refluxing ureters were tapered while five of the obstructing megaureters were tapered.
  
  
  RESULTS
  Twenty-one of the 23 patients were successfully repaired using this method. Complications were minimal.
  
  
  CONCLUSIONS
  The extravesical approach can be used to correct reflux or obstruction in dilated ureters with efficacy equivalent to transvesical repairs.
