Contrast induced nephropathy: updated ESUR Contrast Media Safety Committee guidelines

The Contrast Media Safety Committee (CMSC) of the European Society of Urogenital Radiology (ESUR) has updated its 1999 guidelines on contrast medium-induced nephropathy (CIN). Topics reviewed include the definition of CIN, the choice of contrast medium, the prophylactic measures used to reduce the incidence of CIN, and the management of patients receiving metformin. Key Points aEuro cent Definition, risk factors and prevention of contrast medium induced nephropathy are reviewed. aEuro cent CIN risk is lower with intravenous than intra-arterial iodinated contrast medium. aEuro cent eGFR of 45 ml/min/1.73 m (2) is CIN risk threshold for intravenous contrast medium. aEuro cent Hydration with either saline or sodium bicarbonate reduces CIN incidence. aEuro cent Patients with eGFR a parts per thousand yen60 ml/min/1.73 m (2) receiving contrast medium can continue metformin normally.
