Contrast-induced nephropathy after computed tomography.
BACKGROUND
Contrast induced nephropathy is the third most prevalent preventable cause of acute kidney injury in hospitalized patients. It defined as an absolute increase in serum creatinine ≥ 0.5 mg/dL and relative ≥ 25% increase.


OBJECTIVE
We studied the risk factors to intravenous injection contrast nephropathy after computed tomography.


METHODS
We studied 400 patients prospectively.


RESULTS
The incidence of contrast induced nephropathy, with an absolute or a relative increase were 4.0% and 13.9%, respectively. Diabetes and cardiac failure were independent risk factors for CIN a relative increase de serum creatinine (O.R.: 3.5 [95% CI: 1.92-6.36], p < 0.01, 2.61 [95% CI: 1.14-6.03%], p < 0.05, respectively).


CONCLUSIONS
We showed association between uses of intravenous injection contrast after computed tomography with acute injury renal, notably with diabetes and heart failure.
