Abstract
Acute kidney injury (AKI) is common in patients with liver cirrhosis, occurring in 13-20% of patients hospitalized with decompensated cirrhosis, and is significantly associated with the prognosis. The development and progression of AKI is an independent predictive factor for mortality in these patients. If AKI develops, the renal function declines progressively even if AKI is improved later, the patients have a poorer prognosis compared to those who have not developed AKI. In addition, in patients without appropriate treatment or no improvement with the initial treatment, AKI often progress to hepatorenal syndrome (HRS), which is associated with significant morbidity and mortality. Therefore, early detection and appropriate management for the development of AKI is very important in these patients. Recently, there have been significant revisions in the diagnostic criteria and treatment of AKI and HRS; this manuscript reviews these changes.
