In this article, the authors provide an analysis of the results of diagnosis and treatment of congenital hydronephrosis in children of 691 children with congenital hydronephrosis aged 3 to 15 years on the basis of urological departments of three medical institutions in the Fergana Valley: Andijan Regional Children's Multidisciplinary Medical Center (ADMMC), Namanga Regional Children's Multidisciplinary Medical Center center (NODMMC) and Fegran Regional Children's Multidisciplinary Medical Center of Urology in the period from 2013 to 2022.

The authors conclude that the implementation of the developed methods (modified mini-access, drainage method, improved ureteropyelonastomosis) for congenital hydronephrosis, regardless of the degree of complications and the age of the child, made it possible to reduce the period of postoperative rehabilitation, the need for injection of analgesics and reduce the duration of drainage.
