contrast induced acute kidney injury

Acute kidney injury (AKI) represents a medical emergency associated with poor clinical outcomes. The international guideline group Kidney Disease: Improving Global Outcomes (KDIGO) has defined AKI according to rises in serum creatinine and/or reductions in urine output. Any patient who meets the criteria for AKI should be reviewed to ascertain the cause of AKI and the severity of the injury should be staged. Patients with more severe AKI are at greater risk of progression to chronic kidney disease (CKD).
