Summary:The authors tried to measure renal function quantitatively by an external counting method using131I-Hippuran Renocardiocystogram. For this purpose, we made a system which automatically calculate and record the half decreasing time (T 1/2) of I-Hippuran concentration in blood. Then this external counting method was assessed with 655 cases of various urinary lesions. As the result, with the patients having no urinary retention, a good correlation was found between P.S.P. (15') and T 1/2 ; (r=0.93), while the correlation was relatively low with the patients having urine retention by various lesions. This fact shows that the external counting method is more reliable than the conventional renal function tests which need urine collection. Conclusion : This half decreasing time calculating method with external counting, which requires a patient minimum load, is not only simple to handle but also reliable to evaluate renal function.
