[Acute kidney injury in liver transplantation]

Acute kidney injury (AKI) is a common complication in liver transplant recipients. Affecting ~25% of patients preoperatively, and up to 60% postoperatively significantly worsens the prognosis. Etiology differs depending on the time of its onset, from mostly prerenal before the transplantation, ischemic in the early postoperative period to toxic AKI later on. Liver transplantation is a lenghty and complex procedure with a significant risk of hemodynamic instability, metabolic acidosis and electrolyte disturbances. The article discusses the risk of AKI development in patients undergoing liver transplanation and the indications to renal replacement therapy in the perioperative period.
