Endoscopic correction of primary vesicoureteric reflux.

One hundred and three children with primary vesicoureteric reflux treated by endoscopic injection of Polytef paste between March 1984 and February 1986 have been followed up for periods ranging from 3 to 23 months. Seventy-five per cent of refluxing ureters showed absence of reflux after one injection of Polytef paste; 14% of ureters required two to four sub-ureteric injections of Polytef paste for the correction of vesicoureteric reflux; 8% of ureters showed improvement in the grade of reflux after the initial injection of Polytef paste. Duplex systems were more difficult to correct and recurrence of reflux was much higher than in primary reflux. Follow-up intravenous urograms showed no evidence of ureteric obstruction in the treated ureters. The procedure is safe, simple and effective in correcting all grades of vesicoureteric reflux. To obtain best results, attention should be paid to minute details of the technique and the injection made with pinpoint accuracy.
