Effects of submucosal Teflon paste injection in vesicoureteric reflux: results with 1- and 2-year follow-up data.
One hundred refluxing ureters with grades II (n = 65), III (n = 27) and IV (n = 8) vesicoureteric reflux (VUR) were treated with endoscopic submucosal polytetrafluoroethylene (Teflon) paste injection. Reflux stopped in 77 ureters after a single injection and in 13 ureters following a second injection. Two ureters remained with minimal (grade I) residual reflux, whilst in another 5 improvement from grades III and IV to grade II reflux was noted. In 3 ureters reflux remained unchanged, because of lateral ectopia of the refluxing ureteric ostium, hindering the injection of Teflon into the correct position. Re-evaluation at 1 year postinjection, of 48 previously cured ureters showed recurrence of reflux in 1 (2%), but no further recurrences were noted in 19 ureters reevaluated after 2 years.
