“…Post-operative risk factors for AKI are represented by markers of the severity of the condition, such as mechanical ventilation, length of hospitalization (including in intensive care unit), infectious complications, hemodynamic instability or a high APACHE II score [8,23,25,36,60]. The importance of liver function is also accentuated since the occurrence of AKI is predicted by a lack of recovery of liver function, acute rejection, cholestasis and peak cytolysis [31,42,116]. The occurrence of AKI within 6 to 12 months after transplantation is associated with an increase in the risk of chronic renal disease within 5 years after transplantation [46,62,71,75,76,79,83,87].…”
