Endoscopic treatment of vesicoureteral reflux

Since 1985 we treated 180 cases of vesicoureteral reflux with endoscopic injection of polytetrafluoroethylene (Teflon). Follow-up, from 1985 to 1990, was available for 256 refluxing ureters (93% primary reflux, 7% secondary after reimplantation or neurogenic bladder). The distribution according to the grade was the following: Grade I: 26 cases (always associated with higher grade contralateral reflux), Grade II: 94 cases, Grade III: 97 cases, Grade IV: 28 cases and Grade V: 11 cases. For primary reflux, correction was observed after a single injection in 87% of the cases and 93% after a second injection. So far no long-term morbidity and complications have been observed. The procedure is simple, reliable and successful. We are aware of the ongoing discussion about the safety of the polytetrafluoroethylene paste, particularly in children, and are waiting for the ideal substance preferably prepared from the patient's own tissue.
