Endoscopic Injection of Teflon for Correction of Primary Vesicoureteral Reflux in Children

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 1 3.8%, and unchanged in 1 0.3% of the ureters. The success rate was lower for high grade reflux cases and ureteral orifices with abnormal shapes. Conclusion: 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.
