[Endoscopic treatment of vesico-ureteral reflux by injection of Teflon in children. Preliminary results].

Twenty-three infants and children with primary or secondary vesico-ureteric reflux (representing a total of 38 reflux) were treated by endoscopic injection of Polytef paste with 86% complete corrections of the reflux after the first injection, and 92% after the two injections. These results are comparable to those published so far in the literature. There were no secondary stenosis. There is, however, a need for a more prolonged delay to correctly evaluate its long-term efficiency. This technique appears safe and efficient. Furthermore, it has an interesting economical aspect since it requires a maximum of two days of hospitalisation.
