Live donor renal transplantation--the experience of the Belfast Renal Unit.

Live donor renal transplants are often preferred to cadaver grafts because of better graft survival. In a retrospective study of 41 live donor transplants performed in the Belfast Renal Unit from 1971 until November 1988, actual graft survival at 2 and 5 years was 84% and 69% respectively. Corresponding patient survival rates were 87% and 81%. These results are no better than those of cadaver grafts. A subdivision of patients considered to be relatively poor risk for transplantation showed less favourable results than those who were good risk. 15% of the donors suffered post-operative complications, which occurred more often in older donors. Live donor transplantation is not necessarily preferable to cadaver organ graft, and is not recommended for poor risk recipients or donors aged over 50 years.
