title: Bladder washout and stone formation in paediatric enterocystoplasty.
abstract: OBJECTIVE
  To review the incidence of stone formation in our patients with enterocystoplasty to determine the effect of regular bladder washout.
  
  
  METHODS
  From 1988 to 1995, a prospective cohort of 30 children underwent enteroplasty with continent diversion. Over the same period, a consecutive group of 30 children had an augmentation alone. All were instructed to wash out their bladder on a weekly basis with sterile water. The frequency of the washouts increased if there were problems with increasing mucus production. Their incidence of stone formation has been compared to a similar group of 30 children performing clean intermittent self catheterisation (CISC) on their native bladders.
  
  
  RESULTS
  Five (17%) children with continent diversions formed bladder stones (mean time to formation 35 months, range 13-59 months) were compared with 2 (7%) of children with augmentation. No child performing CISC alone formed stones.
  
  
  CONCLUSIONS
  A regime of regular bladder washout in children with enterocystoplasty did not significantly reduce the incidence of stone formation when compared to previously published data.
