[Contrast induced nephropathy : myth or reality ?]

Contrast induced nephropathy has long been considered as the third cause of inpatients acute renal insufficiency after functional renal insufficiency and acute tubular necrosis. This entity is now controversial. Numerous studies failed to show a direct link between intravenous iodinated contrast injection and a worsening of renal function after injected scanners in patients with normal renal function. The notion of contrast induced nephropathy remains integrated in the practice of the majority of physicians, who often overestimate this risk.
