Abstract
At urography the radiopacity of the pelvis increases with the product of I concentration of the urine and its layer thickness. The layer thickness is proportional to the 3rd root of the volume. The volume of the renal pelvis in rabbits was proportional to the diuresis up to a level of approximately 0.8 ml/min, after which a maximal dilatation seemed to be reached. By this means, the estimated density of the renal pelvis can be calculated. This model of evaluating urographic contrast agents is thought to be more appropriate than and complementary to the mere determination of urinary I concentration.
