Subjective responses and albuminuria induced by ioxaglate during renal angiography in man.

The degree of albuminuria induced by renal arteriography with the monoacid dimeric contrast medium ioxaglate was studied in 19 patients. Ioxaglate did not cause significant changes in urinary albumin concentrations (median concentration after angiography = 0.022 g/g creatinine). The results with ioxaglate are compared with those of an identically designed study performed earlier with the contrast media metrizoate and metrizamide, in which both caused significantly increased concentrations of urinary albumin (1.1 g/g creatinine and 0.96 g/g creatinine, respectively). The degree of pain/heat sensation following semiselective renal arteriography with metrizoate and ioxaglate was also compared using a visual analog scale in 34 patients. Ioxaglate caused no pain and a significantly lower heat sensation than metrizoate.
