CIN is one of the leading causes of hospital-acquired acute kidney injury (AKI). It is associated with a significantly higher risk of in-hospital and 1-year mortality, even in patients who do not need dialysis [3] .

There is a complicated relationship between CIN, comorbidity, and mortality. Most patients who develop CIN do not die from renal failure. [4] Death, if it does occur, is more commonly from either a pre-existing nonrenal complication or a procedural complication.
