Outcomes of reused transplanted kidneys using cases from the Korean Network for Organ Sharing database.

Due to organ shortages, the reuse of transplanted organs may be a good option for potential organ recipients. However, reports on the reuse of transplanted organs are rare. We retrospectively investigated cases of kidney donation since 2000 using the Korean Network for Organ Sharing database. Three cases of retransplanted kidneys were identified between 2000 and 2019. Of these three cases of kidney reuse, two involved reuse after a living-donor kidney transplant, and one case involved reuse after a deceased-donor kidney transplant. Another patient required a graftectomy due to bacterial infection immediately after transplantation. In two cases, the transplants were successful, and the kidneys have been functioning well for over 7 years. We believe that this case report highlights the opportunities for organ reuse among potential organ recipients and alleviates concerns about reused transplanted kidneys.
