Risk factors for acute kidney injury after orthotopic liver transplantation: A single-center data analysis

Abstract

Acute kidney injury (AKI) is a common complication following orthotopic liver transplantation (OLT) and is associated with increased morbidity and mortality. The aim of the current study was to determine the risk factors for AKI in patients undergoing OLT. A total of 103 patients who received OLT between January 2015 and May 2016 in Tongji Hospital, China, were retrospectively analyzed. Their demographic characteristics and perioperative parameters were collected, and AKI was diagnosed using 2012 Kidney Disease: Improving Global Outcomes (KDIGO) staging criteria. It was found that the incidence of AKI was 40.8% in this cohort and AKI was significantly associated with body mass index, urine volume, operation duration (especially > 480 min), and the postoperative use of vasopressors. It was concluded that relative low urine output, long operation duration, and the postoperative use of vasopressors are risk factors for AKI following OLT.
