Study of Contrast - Induced Nephropathy After Intravenous Contrast Procedures at Sohag University Hospitals

Contrast-induced nephropathy (CIN) is a serious complication of angiographic procedures and results from administration of iodinated contrast media (CM). CIN is the third most common cause of hospital acquired acute renal injury representing about 12% of the cases. The reported incidence of CIN varies widely across the literature, depending on the patient population studied and the baseline risk factors . An overall incidence of CIN following intraarterial contrast injection in the general population was reported to be 0.6-2.3%. Although the incidence of CIN is low in patients with normal renal function, its prevalence can be much higher in several patient subsets e.g. diabetics, patients with existing renal insufficiency. Contrast-induced nephropathy is defined as a rise in serum creatinine of at least 0.5 mg/dL or a 25% increase from baseline within 48 to 72 hours after contrast exposure. The Kidney Disease Improving Global Outcome (KDIGO) definition is different, with stage 1 being a rapid rise of creatinine to greater than 0.3 mg/dL within 48 hours or the relative rise of 50% or more from baseline in 7 days or less or a reduction in urine output to less than 0.5 ml/kg/hr for 6 to 12 hours. This severity is further staged based on creatinine levels, urine output, or the need for renal replacement therapy. In most cases of CIN there is an asymptomatic, non-oliguric rise of serum creatinine within 24hours; however, in more severe cases, the creatinine concentration may n…
