Abstract
Summary
A dye dilution method of determining renal blood flow in man is described. This technic requires catheterization of the renal artery and the renal vein but no sampling of urine. Data on 11 patients with measurable urine flow, PAH clearance and PAH extraction ratio, as well as on 4 anuric subjects, are reported. Comparison with the PAH data indicates that the results of the dye method are probably valid. Possible causes of error are discussed.
