Restored Kidney Transplant Between Third Parties

Approximately 30,000 new patients are introduced into dialysis and about 20,000 of them die every year in Japan. At present, about 300,000 patients are on dialysis and more than 10,000 patients are registered to the Japan Organ Transplant Network (JOTN) with the hope for a renal transplantation. If the renal function is restored by transplantation, the quality of life (QOL) improves and more than 90% are reportedly come back to their normal life activities and get relieved from the burden of dialysis. Furthermore, it can reduce the dialysis related medical cost by as much as 50%. However, only about 1,000 renal transplantation cases are annually carried out in Japan. Among them, 80-85% are living renal transplantations offered by family members or relatives, and the rest are from deceased donors.

Due to the fact that the number of deceased donors are scarce and renal transplantations between non-relatives (third parties) are currently not allowed in Japan, the approximate waiting time to receive a renal transplantation is 16 years. For that reason, many patients travel abroad to receive a renal transplantation.

There are reports that total nephrectomies are performed as a treatment for small size (4 cm or less) renal tumors in many cases and that many of these nephrectomized kidneys can be successfully transplanted after surgical restoration with satisfactory results. However, due to the lack of necessary evidence it is currently not allowed in Japan.

Therefore, the investigators planned the present clinical study to evaluate the curative efficacy (renal function, QOL) and safety (side effects, complications or occurence of renal cancer) of living renal transplantations between third parties (non-relatives) with restored donor kidneys after the surgical removal of a small size (4 cm or less) renal tumor, in order to acquire necessary clinical data for potential enrichment of the renal donor pool in Japan as well as to develop useful medical care for our patients who are on dialysis for many years due to the renal failure.
