Contrast-medium-induced acute renal failure and Tamm-Horsfall proteinuria.

Abstract

An acute obstructive nephropathy due to precipitation of urinary glycoprotein-contrast complexes in the renal tubules has been postulated to explain the episodes of renal failure occasionally seen following intravascular contrast medium administration. In an in vitro study we were unable to produce any precipitation of contrast-glycoprotein complexes over a wide range of concentrations, temperatures and pH values in urine with any urographic contrast agent, conventional or new. Meglumine ioglycamide (Biligram: Schering) alone, the strongly protein-binding agent, exhibited the phenomenon, and only in high concentration. It is concluded that such a mechanism is unlikely to play a role in contrast medium nephrotoxicity, which therefore remains unexplained.
