[Endoscopic correction of vesicoureteral reflux by Teflon]

From March 1988, 19 vesicoureteral reflux (VUR) patients were treated by endoscopic injection of Teflon paste. Of these patients 17 cases 27 ureters were followed for more than one year. After injection of Teflon paste, reflux was eliminated in 63%, decreased in 30%, and unchanged in 7%. Then 7 ureters were injected twice and 1 ureter three times. Finally, reflux was eliminated in 93% of all cases, and decreased in 7%. Early complications were fever up in 4 cases, flank pain 3, acute cystitis 1. In the follow up period, acute cystitis occurred in 1 patient, ureter stone in 1, and renal failure in 1. However, the ureter stone and renal failure were probably not caused by this procedure.
