**1. Introduction**

Contrast-induced nephropathy (CIN) is a grave complication of angiographic procedures and arises from administration of iodinated contrast media (CM) [1]. CIN is the third most common cause of hospital acquired acute renal injury representing about 12% of the cases. The incidence of CIN varies from 0 to 24% depending on the patient's risk factors [2]. It is generally a transient and reversible state of acute renal failure [3]. However, the development of CIN is linked to a more prolonged hospital stay, an increased morbidity and mortality, and a high healthcare cost. Treatment of CIN is predominantly of supportive nature, consisting of calculated fluid and electrolyte management; however, dialysis may be required in some cases [3].
