Determination of total and individual kidney function in children by means of 123-I-hippuran whole body clearance and scintillation camera.

In 153 children suffering from various renal or urological disease a total of 179 individual and regional renal clearance studies were performed using 123-I-hippuran and a scintillation camera. The clinical diagnoses and questions before and the therapeutic consequences after clearance determinations are analyzed. The dynamic information fo sequential scintigraphy combined with renal clearance determination allow a quantitative estimation of the individual and regional kidney function. The method is considerably helpful in cases of unilateral small kidneys, obstructive uropathies, duplication of the urinary tract, and segmental renal disease.
