Contrast Media Nephropathy: In Depth Review

Contrast nephropathy (CN) remains a common cause of acute renal failure in patients undergoing radiocontrast study. [1] It is the third leading cause of hospital-acquired acute renal failure (ARF) after hypotension and surgery. [2] CN is associated with both short- and long-term morbidity and mortality, [3] with estimates of in-hospital mortality rates are as high as 34% in patients who develop ARF compared with 7% in those who do not. [3] There is continued controversy about the pathogenesis of this entity despite the better understanding of its risk factors.
