Early acute kidney injury after liver transplantation in patients with normal preoperative renal function.

•AKI was a frequent complication in LT recipients with normal preoperative renal function.•BMI of > 25, prolonged IVC clamping, prolonged cold ischemia time, and post-operative RBC requirements of > 10 units might be risk factors for AKI after LT.•AKI had both negative short- or long-term effects on patient outcomes, also the severity of AKI had a dose-response relationship with worse outcomes.•Massive RBC transfusion might be associated with infection and RRT after LT.
