Recent issues in contrast-induced nephropathy

Abstract

Contrast-induced nephropathy (CIN) is a serious complication resulting from the use of iodinated contrast medium (CM) with potentially high morbidity and mortality. Patients with pre-existing renal insufficiency appear to be at higher risk of CIN. To prevent CIN among patients undergoing contrast-enhanced computed tomography, every effort is required, including routine identification of at-risk patients, the use of appropriate hydration regimens, withdrawal of nephrotoxic drugs, selection of low-osmolality CM or iso-osmolar CM, and using the minimum volume of CM possible.
