title: Impact of preoperative chronic renal failure on liver transplantation: a population-based cohort study.
abstract: OBJECTIVE
  The purpose of this study was to assess whether preoperative chronic renal failure (CRF) affects the rates of postoperative complications and survival after liver transplantation.
  
  
  METHODS
  This population-based retrospective cohort study included 2,931 recipients of liver transplantation performed between 1998 and 2012, enrolled from the Taiwan National Health Insurance Research Database. Patients were divided into two groups, based on the presence or absence of preoperative CRF.
  
  
  RESULTS
  The overall estimated survival rate of liver transplantation recipients (LTRs) with preoperative CRF was significantly lower than that of patients without preoperative CRF (P=0.0085). There was no significant difference between the groups in terms of duration of intensive care unit stay, total hospital stay, bacteremia, postoperative bleeding, and pneumonia during hospitalization. Long-term adverse effects, including cerebrovascular disease and coronary heart disease, were not different between patients with versus without CRF.
  
  
  CONCLUSIONS
  These findings suggest that LTRs with preoperative CRF have a higher rate of mortality.
