ABSTRACT
In the animal experiments, glomerular filtration rate (GFR) values were estimated from the urinary response to the intravenously administrated iopamidol. By introducing some reasonable assumptions, mass balance equations about the contrast medium were transformed and GFR was defined as the ratio of logarithm of urinary concentration by time. Urinary concentrations were determined by measuring the photodensity on the X-ray film of urine specimens. Obtained values of GFR were well fitted to those obtained by the analysis of the plasma disappearance curve. The advantage of this method is that measurement of urinary volume is not necessary.
