Sub uretric injection of teflon was used in 62 adults patients (92 ureteral units, 30 bilateral cases), 49 females, 13 males for treatment of congenital VUR, in 76 cases the refux was permanent. Degree (D) I = 18 Ureters (U), D II = 28 U., D III = 22 U., D IV = 7 U and D V = 1 U. Follow-up consisted in ultrasound examination cystogram and IVP performed at one month (92 U.) three months (81 U), one year (64 U) and two years (12 U). The procedure was performed under general anaesthesia. The quantity of polytef varied from 1 to 2 cc. Correction of VUR was observed in 70/92 U (76.1%), 11 persistent VUR were treated by reinjection of politef and in six VUR disappeared (83% total correction). Recurrence was observed in 4 patients, at 3 months, one year and two years (2 cases). 3 patients had reinjection (2 success, 1 failure). Through long term results are still to be evaluated. The results at one and two years seems to confirm the inoucuity and the effectiveness of endoscopic procedure for treatment of congenital VUR.
