title: Incidence of contralateral vesicoureteral reflux following unilateral extravesical detrusorrhaphy (ureteroneocystostomy).
abstract: OBJECTIVE
  The development of contralateral vesicoureteral reflux following different types of unilateral antireflux surgery has been reported to be as high as 22%. We review our recent experience with unilateral extravesical detrusorrhaphy in regard to the incidence of postoperative contralateral vesicoureteral reflux.
  
  
  METHODS
  Between 1990 and 1995, 72 children underwent unilateral extravesical detrusorrhaphy. Of 73 refluxing renal moieties (1 patient had reflux in both moieties of a completely duplicated kidney) reflux grade was II in 35 (48%), III in 25 (34%), IV in 11 (15%) and V in 2 (3%). Common sheath reimplantation for complete ipsilateral duplication was performed in 16 patients.
  
  
  RESULTS
  One patient had grade I postoperative ipsilateral vesicoureteral reflux resulting in a success rate of 98.6%. In 4 patients (5.6%) contralateral vesicoureteral reflux developed, and was grade II in 3 and grade I in 1. In all patients contralateral reflux resolved at 16, 17, 18 and 31 months of followup. No additional surgery was required in any patient. There was no association between the incidence of contralateral vesicoureteral reflux, and patient age, gender, preoperative ipsilateral reflux grade and presence of ipsilateral duplication.
  
  
  CONCLUSIONS
  Unilateral extravesical detrusorrhaphy is a highly successful procedure with a low incidence of postoperative contralateral vesicoureteral reflux. Should reflux develop, it is of low grade with a significant rate of spontaneous resolution.
