In patients with end-stage liver graft disease and CKD, liver retransplantation associated with kidney transplantation (ReLT-KT) might be necessary. Yet, this specific subset of patients remains poorly described. Methods. Indications, perioperative characteristics, and short- and long-term outcomes of patients undergoing ReLT-KT at 2 transplantation units from 1994 to 2012 were analyzed. Risk factors for postoperative mortality and long-term survivals were evaluated. Results. Among 3060 patients undergoing liver transplantation (LT), 45 (1.5%) underwent ReLT-KT. The proportion of ReLT-KT among LT recipients continuously grew throughout the study period from 0.3% to 2.4% (P < 0.001). Median time from primary LT to ReLT-KT was 151.3 (7.5–282.9) months. The most frequent indications for liver retransplantation were recurrence of the primary liver disease and cholangitis in 15 (33.3%) cases each. CKD was related to calcineurin inhibitors toxicity in 38 (84.4%) cases. Twelve (26.7%) patients died postoperatively. D-MELD (donor age × recipients’ MELD) was associated with postoperative mortality (HR: 8.027; 95% CI: 2.387-18.223; P = 0.026) and optimal cut-off value was 1039 (AUC: 0.801; P = 0.002). Overall 1, 3, and 5 years survivals were 68.8%, 65.9%, and 59.5%, respectively. D-MELD > 1039 was the only factor associated with poor survival (P = 0.021). Conclusions. ReLT-KT is a highly morbid increasingly performed procedure. Refinements in the selection of grafts and transplant candidates are required to limit the postoperative mortality of these patients.
