The visualization of non-ionic contrast medium (Omnipaque 300) in the excretory urography by bolus injection was examined with regard to the normal sided urinary tract in patients with urolithiasis using a densitometer and further compared with that of ionic contrast medium (60% Urografin). In relation to the photographing method, both contrast media showed an increasing frequency of high opaque site in the order of Tomo, A-P and P-A images, which tended to shift from the upper to the lower urinary tract. In relation to the site of determination, both agents showed a good image in the upper urinary tract by the each photographings, while P-A image was better than A-P image in the lower urinary tract, suggesting their high usefulness for the imaging diagnosis. The visualization in relation to the contrast medium used was better in Omnipaque 300 groups than in 60% Urografin group with a significant difference (P less than 0.05-0.01) in the calyx and pelvis of the kidney by the each photographings, suggesting a high usefulness of non-ionic contrast medium. A densitometer seemed to be a useful means for evaluation and examination of the visualization with excellent objectivity as compared with conventional macroscopic methods.

Changes in the visualization of non-ionic contrast medium (Omnipaque 300) in the urography by DIP were monitored for the normal sided urinary tract in patients with urolithiasis using a densitometer. In addition, changes of the visualization in relation to the dose of contrast medium used was examined and compared with that of ionic contrast medium (60% Urografin). The optimum photographing time was 15 minutes in the upper urinary tract (nephrogram, calyx, pelvis, upper ureter) and 20 minutes in the lower urinary tract (lower ureter, urinary bladder). Visualization of high usefulness appeared to be obtainable for the imaging diagnosis by DIP in subjects with normal renal function even when the photographing was completed 20 minutes after infusion of contrast medium. In relation to the doses of contrast medium used, no difference was observed in the variation pattern but a better imaging was obtained in the 100 ml group than 50 ml group with a significant difference (P less than 0.01) in the 15-20 minute images of the calyx and pelvis of the kidney and urinary bladder in particular, this suggested the high usefulness of 100 ml dosing for the imaging diagnosis. In the visualization of ionic contrast medium, some difference was observed in the variation pattern and the visualization was better in Ominpaque 300 groups than in 60% Urografin group with a significant difference (P less than 0.01) in the 15-20 minute images of the calyx and pelvis of the kidney and urinary bladder. This suggested the high usefulness of non-ionic contrast medium.
