Treatment of vesicoureteral reflux in children by endoscopic injection of Teflon. Review of 2 years of experience.

Abstract

Endoscopic subureteral injection of Teflon was performed in 113 children (217 ureters) to correct all types of vesicoureteral reflux. In all cases immediate disappearance of the reflux was noted on an operative cystogram. Two-hundred and thirteen ureters were controlled at 1 month. Reflux had disappeared in 85.11% of the cases after a single injection and after 2 injections in 89.3% of the cases. The results remained stable in 93.22% of the cases at 1 year. Most relapses were explained by an insufficient quantity of Teflon and difficult anatomical conditions. Indications for this technique and the safety of the paste used are discussed.
