Perioperative renal protection strategies in liver transplantation.

Renal failure is one of the most common and major complications in liver transplant recipients. It has been reported to occur at an incidence of 17% to 95%. This complication is associated with prolonged hospital stay in the intensive care unit, the need for postoperative dialysis, infectious complications, acute rejection, and increased mortality. The causes of renal function deterioration differ in the preoperative and postoperative periods. By identifying patients at risk of developing chronic renal failure and by implementing strategies for renal protection at an early stage, it is possible to slow down the progression of renal failure and improve the long-term outcomes in liver transplant recipients.
