A recent observational study reports that after cardiac surgery, clinical outcomes differ significantly between patients with the same stage of acute kidney injury (AKI) depending on the diagnosis criteria used: urine output, serum creatinine or both. This finding emphasizes the limitations of current criteria for AKI risk stratification and diagnosis.
