| Abstrakt: | Purpose: Marginal cadaveric renal transplant donors represent a potential source for expansion of the donor pool but these kidneys have generally demonstrated significantly poorer survival compared to those from conventional donors. A strategy to provide sufficient renal mass for adequate nephron dosing and subsequent improved survival is the use of both kidneys for a single recipient. We present our 2-year experience with double renal transplants from marginal donors. Materials and Methods: During an 8-year period 28 patients received double renal transplants (group 1) and 31 received a single transplant (group 2) from marginal donors. Donors were older than 55 years, or had diabetes mellitus, hypertension, greater than 15% glomerulosclerosis on biopsy, increasing creatinine or intrinsic renal parenchymal disease. Results: Both groups were of similar age and the number of rejection episodes per year was similar but followup time differed (22.4+/-14.6 months for group 1 versus 43.7+/-20.5 for group 2). Male-to-female ratio, cold ischemia time, terminal creatinine and pre-transplant biopsy rates were similar for donors in both groups. Average donor age was younger in group 1 (48.9+/-15.8 versus 57.5+/-8.2 years, p = 0.01), and incidence of intrinsic renal disease and increasing donor creatinine was greater (12 versus 2, p = 0.002 and 4 versus 0, p = 0.04, respectively). Incidence of primary nonfunction (1 group 1 versus 5 group 2 patients) and delayed graft function (6 versus 7) was similar. The 1 and 2-year graft survival rates of 96% and 96%, respectively, for group 1 were significantly higher than those for group 2 (77% and 73%, p = 0.02). Conclusions: Our experience to date with double kidney transplants from marginal donors demonstrates acceptable 1 and 2-year survival rates significantly superior to the outcome using only 1 marginal kidney. This finding has important implications in the decision to use marginal donors in regard to cost-effectiveness and patient survival compared to the alternative of continued hemodialysis until an ideal donor organ becomes available. |
