The article presents the results of a retrospective study of the diagnosis and treatment of 379 children aged 2 months to 15 years with diagnosed congenital obstructive uropathy. The state of urodynamics of the upper urinary tract and kidney function was assessed by Informative methods of mathematical analysis of X-ray examination of children with obstructive uropathy (OU).

Purpose. To improve the diagnostic information content of X-ray diagnostics in case of obstructive uropathy by using the program to determine the degree of anatomical and functional changes in the kidneys and ureters.

Material and methods. X-ray studies were carried out in 379 patients. Of these 249 patients had congenital hydronephrosis (141 before surgery and 108 after surgery). Congenital ureterohydronephrosis were diagnosed in 130 children (74 before surgery and 56 after surgery). Morphological studies were carried out in 118 children (72 patients with congenital hydronephrosis and 46 patients with congenital ureterohydronephrosis).

Results. There was no significant difference in X-ray planimetry data of the healthy children compared with diagnosed congenital hydronephrosis and ureterohydronephrosis of the 1st degree of obstruction. At the 2nd degree of obstruction segmental and fragmentary hypoplasia of the muscular membrane of the ureter with disorientation of the muscle bundles led to a significant increase in the values of RMO and VMO p≤0.01 and p≤0.001, respectively, compared with the normal ones. The functional state of the renal parenchyma does not suffer significantly, this was confirmed by the absence of confidence differences in X-ray planimetric (RCT, PI) parameters with normative data. At the 3rd degree of obstruction progressive sclerosis and atrophy of the walls of the upper urinary tract led to a significant increase in the renocortical index and the volume of the obstructive ureter compared with the normative data and indicators of children with 2nd degree of obstruction. The development of scarring of the kidney parenchyma resulted in a significant decrease in the parenchymal index on excretory urogramms (p≤0.01).

Conclusion. X-ray planimetry plays an important role into the assessment of the functional state of the kidneys and ureters, improves the diagnosis of obstructive uropathy in children for prevention the development of nephrosclerosis and chronic renal failure, as well as to predict the course of the disease.
