[Current status and future of clinical kidney transplantation in Japan]

Kidney transplantation has been established to be the therapy for an end-stage renal disease. In Japan, living donor kidney transplantation is frequently performed (> 80%) because of a shortage of the deceased donors. The graft survival has been improved to 93.4% (5-year graft survival in living donor kidney transplantation after 2001). ABO-incompatible cases are increasing and more than 20% are ABO-incompatible in Japan (30% in our institution). In our institution, 225 kidney transplantations (182: living donors, 43: deceased donors) have been performed from 2004.4 to 2010.6. Although the graft survival is excellent, posttransplant infections including cytomegalovirus, EB virus and BK virus are problems which should be solved. For the safety of the recipients, we should use kidney grafts from brain-dead donors.
