title: [Endoscopic treatment of bilateral vesicoureteral reflux in children].
abstract: Endoscopic treatment of bilateral vesicoureteral reflux (VUR) was made in 8 boys and 28 girls (a total of 58 collagenizations in various modifications). Secretory function of the kidney was studied before surgery and obstruction of the vesicoureteral segment was excluded. Cystoscopic picture was analysed. The analysis of correlations between efficacy of antireflux collagenisation of the ureteral ostium and ureteral ostium position and shape, renal function leads to the conclusion that submucosal endoscopic collagen implantation in the abnormal ostium in its lateroposition is not effective. This was confirmed by pathomorphological investigations of VUR which discovered dramatic impairment by smooth muscle atrophy type with fiber dyscomplectation, perimuscular sclerosis. Thus, endoscopic treatment of bilateral VUR in children is safe, but its efficacy depends on valid choice of indications. In congenital VUR caused by dysplasia of vesicoureteral segment a preferable treatment is ureterocystoanastomosis.
