[Radioisotope renography in the assessment of kidney function and urodynamics in children following the surgical treatment of hydronephrosis].

The paper provides radionuclide findings in children surgically treated for hydronephrosis. Altogether 109 children were operated on according to the technique by Andersen-Hines-Kucher with ureteral intubation and pelvic drainage. The radionuclide investigation allows determination of the time needed for functional recovery of the operated on kidney as well as visualization of changes in the contralateral follow-up period. Preoperative age-related changes in recovery of secretory and excretory functions of the operated on kidney were investigated.
