Multicenter survey of endoscopic treatment of vesicoureteral reflux in children.

17 centers answered an inquiry on the endoscopic treatment of vesicoureteral reflux. 844 children were reviewed representing 1,290 ureters treated by endoscopic injection of Teflon. The first results in cases of primary or secondary reflux showed a success rate of 82.3%. All authors report low morbidity and excellent tolerance of this technique. In view of the long-term prognosis, these results should be reanalyzed, the median follow-up presently being 1 year. The next logical step should be the development of implant material with a higher biocompatibility but the identical physical properties as Teflon.
