[Contrast-induced acute kidney injury].

The nephrotoxicity of iodinated contrast agent/media is defined by acute renal failure occurring within 48 to 72 hours after injection of iodized contrast product, in the absence of other etiology. The risk factors for contrast agent renal injury must systematically be sought before the exam. The presence of risk factors, including the existence of a renal failure defined by a creatinine clearance (eGFR) of less than 60 mL/min/1.73 m, requires to take prevention measures including hydration. If eGFR is less than 30 mL/min/1.73 m, the advice of a nephrologist is necessary.
