OBJECTIVE To determine the outcome of renal transplants from living related donors. METHODS Retrospective analysis of 33 living related donor renal transplants done between March 1976 and 31 December 1994 at Christchurch Hospital. RESULTS One of the 33 renal transplants patients received an ABO incompatible kidney and was excluded from the statistical analysis. Twenty-one (66%) of 32 grafts continue to function. The 1, 5 and 10 year graft survival rates were 82%, 73% and 48%, respectively. The estimated 1 and 10 year patient survival rates were 96% and 94%, respectively. With the introduction of cyclosporin the 1 and 5 year graft survival rates increased to 90% and 80%, respectively. Three patients received donor specific transfusion preconditioning and one patient a skin graft from the prospective donor. Four patients (12.5%) had current and/or peak panel reactive antibody titres of more than 25%. Three of these grafts failed after 2, 95 and 463 days. Two grafts were lost due to catastrophic vascular complications. CONCLUSIONS The overall outcome for patients who were not highly sensitised was excellent. The degree of sensitisation of the recipient, and the extent of atherosclerotic vascular disease in the recipient, were major predisposing factors for the graft loss due to rejection and vascular complications during the early post transplant period.
