Abstract
From November 1986 to April 1990, 326 refluxing ureters in 197 children were treated by endoscopic injection of Teflon paste. Complications were observed in only 3 cases: 1 child had immediate bilateral ureteral stenosis requiring surgery at 48 h. In 1 case it was impossible to probe 1 ureteral orifice after injection, and Cohen reimplantation was immediately performed; in a 3rd case ureteral dilatation occurred 1 year later without anatomic stenosis at surgery. Three hundred twenty-two ureters were examined after 1 month: reflux had disappeared in 286 (88.82%). The stability of these results after one injection was verified 1 year later for 179 ureters: recurrence of reflux was observed in 19 cases (10.60%); 21 non refluxing ureters were again examined 2 years later: reflux reappeared in 2 cases. Analysis of the midterm results showed that failure was observed in 17.31% of cases of primary reflux and 19.04% of malformative or secondary refluxes. It was more significant in grade IV or V (21.11%) than in grade I–III (16.85%) reflux. Of the 57 immediate or secondary residual refluxes, 10 were followed and 2 spontaneously disappeared, 24 underwent successful surgical reimplantation, and 23 had a repeat injection with 22 successes and only 1 failure that was secondarily cured by surgery. Overall, reflux disappeared after one or two injections in 165 children (83.25%).
