Elimination of the nonionic contrast medium iopromide in end-stage renal failure by hemodialysis.

The increasing life-expectancy of patients with end-stage renal failure has led to a significant increase of diagnostic and interventional radiologic measures. The contrast media used in these procedures, however, are excreted only very slowly, due to the renal failure. We have therefore studied the elimination of the nonionic x-ray contrast medium iopromide (Ultravist) during dialysis in nine anuric patients with end-stage renal failure.
