[Our experience in endoscopic teflon treatment in vesicoureteral reflux in children].

We report our experience with the endoscopic treatment of vesicoureteral reflux by submucosal injection of Teflon (STING) in children. Since December of 1992, 45 children and a total of 67 ureters were treated. The overall success rate was 90% after one injection and 95% after two injections. The success rate was better in primary reflux with 95%, 87.5% in duplicated ureters and 75% in secondary reflux after one injection. Actually we treat the reflux grade II and III with STING when it doesn't improve after one year with medical treatment.
