131 children with congenital hydronephrosis (CH) underwent a surgery. The patients were divided into 2 groups: group I (n=91) with children from 1 month old to 1 year old, and group II (n=91) with children from 1 to 3 years old. Analysis of surgical treatment results has shown that the frequency of intra- and postoperation complications in the both groups was the same. Good and satisfactory results were noted in 89 (98%) patients from group I and in 38 (95%) patients from group II. This reveals a high effectiveness of surgical treatment and feasibility of early correction of the defect. The conducted studies show that the long-term follow-up of children with congenital hydronephrosis is insufficient.

Early correction of pyeloureteral segment obstruction (PSO) in the lack of infection allows to preserve the renal function and creates optimal conditions for subsequent development and growth of renal tissue functional structures.
