    Abstract:
    As part of a general safety study of iopamidol, a nonionic iodinated contrast agent, urine N-acetyl-beta-glucosaminidase enzyme assays were done to compare the renal toxicity of iopamidol with that of iothalamate and diatrizoate. In a randomized study of 30 patients for computed body tomography and another 30 patients for angiography, 10 in each group were injected with iopamidol, 10 with iothalamate, and 10 with diatrizoate. After computed tomography or angiography with the three agents, there was no significant difference in urinary enzyme levels among the groups. The nephrotoxicity of iopamidol appears equivalent to that of diatrizoate and iothalamate.
