[Results of upper urinary tract malformations correction in adults operated in childhood]

3-13-year follow-up results are presented for 83 adult patients operated in childhood for ureterohydronephrosis, hydronephrosis, vesicoureteral reflux. Positive results were obtained in adults operated in early childhood when renal and urinary compensatory mechanisms were stronger. In hydronephrosis and vesicoureteral reflux the results were better than in ureterohydronephrosis. Combined clinical, morphological and experimental investigations have revealed a direct relationship between renal, ureteral functional reserves in adult patients and age of the correcting operation in childhood, degree of intactness of the kidneys and urodynamics, regenerative ability of leiomyocytes.
