Cytotoxic Effects of Ionic High-osmolar, Nonionic Monomeric, and Nonionic Iso-osmolar Dimeric Iodinated Contrast Media on Renal Tubular Cells in Vitro

Abstract

Besides hyperosmolality, direct cytotoxic effects of contrast media molecules contribute to their cytotoxic effects. Results of this study indicate that dimeric contrast media molecules have a greater potential for cytotoxic effects on proximal renal tubular cells in vitro than do monomeric contrast media molecules.
