Renal Blood Flow in Anuric Human Subject Determined by Use of Radioactive Krypton 85

Abstract
A new method independent of urine analysis was presented for the determination of renal blood flow in man using the inert gas radioactive krypton 85. Patients (4) with acute anuria and 6 subjects with normal kidney function were studied. During anuria the renal blood flow and O2 consumption were reduced to approximately 20 and 25%, respectively, of normal values. Follow-up studies in 2 of the anuric subjects when CInulin, CPAH, CUrea, and CCreatinine had become normal revealed normal values for renal blood flow and O2 consumption.
