Renal impairment after living donor liver transplantation

BACKGROUND: There are few reports of postoperative renal impairment after living donor liver transplantation (LDLT). METHODS: We reviewed 246 LDLT recipients to examine the effects of postoperative renal impairment on the results of LDLT. RESULTS: The incidence of renal impairment and the requirements for postoperative renal replacement therapy were 29% and 9%, respectively. Intraoperative blood loss (P<.0001) and preoperative serum creatinine (P=.0002) were significant independent risk factors for the development of early renal dysfunction. Patients who required renal replacement therapy had a lower survival rate (P=.01). CONCLUSIONS: We identified the risk factors for postoperative renal impairment, providing useful metrics to establish a treatment strategy for high risk liver transplant patients.
