PURPOSE We report the preliminary results of endoscopic treatment of vesicoureteral reflux in children using polyacrylate polyalcohol copolymer. MATERIAL AND METHODS We performed a prospective multicenter review of pediatric patients treated with subureteral injection of a new nonabsorbable substance. Only patients with 1 year of followup were included. RESULTS A total of 83 patients underw...

BACKGROUND/PURPOSE It is still under discussion which is the best tissue augmenting substance for the endoscopic treatment of children with vesicoureteral reflux (VUR).
