A total of 1,773 kidney transplants including 1,648 from living donors, 19 from non-heart-beating donors and 106 from heart-beating donors were performed in 2021 in Japan. The data obtained from the Japanese Renal Transplant Registry are shown and analyzed in this annual report. The characteristics of recipients and donors such as relationships, original diseases, duration of dialysis therapy, blood transfusion, status of viral antigens and antibodies, pretransplant complications, causes of death of deceased donors, ischemic time and histocompatibilities are described. In addition, immunosuppressants used initially and other treatments are analyzed. We also report the results of a follow-up survey for recipients and living donors.
