Radio Contrast Induced Nephropathy (RCIN) remains a well recognized complication in patients undergoing diagnostic or interventional procedures requiring radiographic contrast agents and is the third leading cause of acquired acute renal failure in hospitalized patients. Strategies for the prevention of radiocontrast nephropathy have focused on countering vasoconstriction (pre-hydration, fenoldopam, and theophylline), enhancing flow through the nephron (diuretics), or protection against oxygen-free-radical injury (urinary alkalinization and N-acetylcysteine).
