    Abstract:
    PURPOSE: To investigate the acute renal effects of three contrast media in a double-blind randomized parallel-group study. The contrast media investigated were: the nonionic dimeric iso-osmolality medium iodixanol; the nonionic monomeric medium iomeprol; and the ionic dimeric medium ioxaglate. MATERIAL AND METHODS: A total of 30 patients were given the following doses of contrast medium: 10 patients received iodixanol 320 mg I/ml; 10 received iomeprol 300 mg I/ml; and 10 received ioxaglate 320 mg I/ml. The doses were given intra-arterially at routine abdominal angiography and the renal effects of these three contrast media were studied for up to 120 min after injection. RESULTS: The urinary minute volume increased immediately after angiography but tended to return to baseline values after 120 min; these changes were more pronounced with iomeprol and ioxaglate than with iodixanol. Creatinine clearance was not reduced by any of the contrast media. Fraction excretion of sodium increased immediately and lasted for 30 min after angiography; these changes were more pronounced with ioxaglate than with iomeprol and iodixanol. Urinary gamma-glutamyl transferase increased for 120 min after angiography with iodixanol and iomeprol; these changes were more pronounced with iomeprol than with iodixanol. On the other hand, urinary nu-acetyl-beta-glucosaminidase increased for 120 min after angiography with iomeprol, but was unchanged with iodixanol. CONCLUSION: The use of contrast media induces osmotic diuresis and its acute effects on the proximal tubular function. However, the iso-osmolality medium iodixanol induces fewer changes than the other two media.
