title: Endoscopic injection of Teflon for correction of primary vesicoureteral reflux in children.
abstract: BACKGROUND
  Treatment of vesicoureteral reflux by endoscopic injection of Teflon paste has recently demonstrated a good success rate. This report describes our experience in treating vesicoureteral reflux in children with particular reference to follow-up data.
  
  
  METHODS
  Between December 1993 and November 1994, endoscopic injection of Teflon paste into the submucosa was performed on 18 children (29 ureters) to correct vesicoureteral reflux.
  
  
  RESULTS
  After treatment, reflux was eliminated in 75.9%, decreased in 13.8%, and unchanged in 10.3% of the ureters. The success rate was lower for high grade reflux cases and ureteral orifices with abnormal shapes.
  
  
  CONCLUSIONS
  Long-term follow-up for up to 2 years demonstrated that although late recurrence may occur in a small proportion of cases, the procedure is safe, simple and effective for correcting vesicoureteral reflux.
