Background: Living-kidney transplantation is increasing because of the scarcity of kidneys from deceased donors and the increasing numbers of patients on waiting lists for a kidney transplant. Living-kidney transplantation is now associated with increased long-term patient- and allograft-survival rates. Objectives: The purpose of this retrospective study was to identify, in a cohort of 44 ABO-incompatible (ABOi) live-kidney transplant patients, the main complications that occurred within 6 months post-transplantation, and to compare these findings with those from 44 matched ABO-compatible (ABOc) live-kidney transplant patients who were also from our center. Patients and Methods: This single-center retrospective study assessed post-transplantation complications in 44 ABO-i versus 44 matched ABO-c patients. All patients were comparable at baseline except that ABO-i patients had greater immunological risks. Results: During the 6-month post-transplant period, more ABO-i patients presented with postoperative bleeds, thus requiring significantly more blood transfusions. Bleeds were associated with significantly lower values of fibrinogen, platelets, prothrombin time, and hemoglobin levels. Surgical complications, patient- and graft-survival rates, and kidney-function statuses were similar between both groups at 6 months post-transplantation. Conclusions: We conclude that impairment of hemostatic factors at pre-transplant explained the increased risk of a post-transplant bleed in ABO-i patients.
