Radionuclide imaging studies are generally accepted procedures in pediatric nephrology. As minimally aggresive causing no alergic reactions and with law radiation exposure they can be applied to any child irrespective of age and current state of renal function. Radionuclide methods mainly indicated in children are dynamic imaging renography, renal scintigraphy and radionuclide cytography. Dynamic imaging studies including diuretic renography indicated in congenital renal anomalies and obstructive renal diseases, in evaluation of renal function, parenchymal morphology and the detection of vesicoureteral reflux. With captopril stimulation it enables the screening of renovascular hypertension. ^99mTcDMSA scintigraphy is the method of choise in studing acute pyelonephritis and renal scarrs. Radionuclide cystography is generally accepted procedure in detection and follow-up of vesicoureteral reflux irrespective of age and sex. The validity of each radionuclide procedure with currently accepted indications, strenghts and weaknesses of applied methods is presented. According to main indications in pediatric nephrology such as urinary infection, vesicoureteral reflux, obstructive anomalies and hypertension, diagnostic program based on radionuclide procedures and ultrasonography is disccused.
