In order to estimate the renal plasma flow and glomerular filtration rate during the course of renography, a method was developed using simultaneously 131I Hippuran and 169Yb DTPA. First results obtained in a survey of approximately 200 patients are encouraging. The method permits an accurate evaluation of the renal function. In addition, by comparing the clearance rate of the two radiocompounds one can also obtain some interesting diagnostic information which can contribute usefully to the interpretation of renographic tracings and/or gamma camera sequential images.
