Abstract
The article discussed preliminary results of endoscopic correction of vesicoureteral reflux in children using polyacrylate polyalcohol copolymer (Vantris). Injections of polyacrylate polyalcohol copolymer were distributed to 33 patients of the urology department of the Filatov Pediatric Hospital between 2009 and 2014. There were 18 boys and 15 girls of average age of 3.5 years (between 3 months and 16 years). Fourteen patients had bilateral reflux (42.4%) and nineteen patients had unilateral reflux (57.6%). There were 47 injected ureters. Eighteen patients had IV grade reflux (38.9%), 22 patients had III grade reflux (46.2%), and seven patients had II grade reflux (14.9%). Injected volume per unit was 0,76 ± 0,43 ml. Follow up median was 20 months. Reflux was eliminated in 38 renal units (76.7%), decreased to grade I-II in 9 (19.1%) and persisted in 1 (2.2%). One patient experienced uretral obstruction (2.2%). It was treated with Cohen transtrigonal ureteric reimplantation surgery. Overall success level was 95.6%.
