[Neutral alpha-glucosidase activity in the urine in congenital hydronephrosis in children].

Enzymuria was studied in children who had undergone surgery for congenital hydronephrosis. A total of 109 patients were operated on according to Andersen-Hynes-Kucher with ureteral intubation and pelvic drainage. The course of renal tissue tubular function recovery upon elimination of the obstruction in the pyeloureteral segment was followed up by urine activity of neutral alpha-glucosidase as was the enzyme activity dynamics in dysplastic congenital hydronephrosis. The latter evidences reduced, but satisfactory functional capacity of the operated on organs.
