title: The UNOS Scientific Renal Transplant Registry.
abstract: 1. One-year graft survival rates were 80%, 74%, and 66% for recipients of first (27,755), second (4,263), and multiple (914) cadaveric renal transplants, respectively. The 1-year patient survival rate was 94% for recipients of first or second grafts and 92% for multiply retransplanted patients. Half-lives projected for all cadaver transplants surviving the first year were approximately 8 years. 2. One-year graft survival rates were 95% for recipients of HLA-identical sibling-donor transplants (1,493), 91%, 90%, and 89% for recipients of 1-haplotype-matched sibling (1,787), parent (2,118), and offspring (715) donor grafts, respectively. One-year patient survival was 94% for parents receiving transplants from their children and 98% for all other recipients of kidneys from immediate family members. Projected half-lives were 26 years for HLA-identical grafts and 12-14 years for 1-haplotype-mismatched transplants from living related donors. 3. There were 181 transplants between spouses, with a 1-year graft survival rate of 92% and 99% patient survival. There were also 369 transplants from distant relatives or unrelated living donors with a 1-year graft survival rate of 86% and 95% patient survival. Projected half-lives for these transplants were 13 years. 4. Rejection episodes that occurred during the initial transplant hospitalization were reported in 24% of first and 33% of retransplanted recipients (p < 0.001). Rejection-free patients had an 85% 1-year graft survival rate compared with 67% and 58% in recipients of first or regrafts after early rejection (p < 0.001). Rejection episodes were strongly associated with histoincompatibilities. Among HLA-identical sibling transplants, 6% had early rejection compared with 12% of HLA-A,B,DR-matched cadaver transplants, 25% of parent-donor transplants and 28% of HLA-DR-mismatched cadaveric transplants. 5. The serum creatinine level (SCr) reported at the time of discharge was predictive of graft survival in both the short and long term. Recipients of first cadaver transplants discharged with SCr below 1.6 mg/dl (8,960) had a 91% 1-year graft survival rate and a projected half-life of 12 years, while those with SCr above 3.5 mg/dl had 49% 1-year graft survival and 5.3-year projected half-life (p < 0.001). Discharge SCr was significantly influenced by the recipient's weight, the donor's age, and the cold ischemia time.(ABSTRACT TRUNCATED AT 400 WORDS)
