Evaluation of the effectiveness of vesicoureteral reflux treatment in children by endoscopic implantation of Teflon paste

: The paper assesses the results of treating 193 vesicoureteral refluxes of all forms and degrees in 135 children aged 1.5-14 years by endoscopic submucosal implantation of Teflon paste. The contraindication for surgery is acute urinary infection. With a flexible injection needle, Teflon paste (ETHICON, Germany) in doses 0.3 to 4.5 ml was infused under the ostium of the diseased ureter under endoscopic control to form a tight tubercle with closed ostia on the apex. Five (2.6%) cases displayed obstructive pyelonephritis in the early period. Late outcomes were followed for on 55 ureters. There was a positive result in 51 (92.7%). In come cases repeated interventions were needed for acute liquidation of the reflux.
