Living-unrelated kidney transpantation: a real source in the Cyclosporine era.

SINCE THE start of kidney transplantation the use of living-related donors (LRDs) has been a regular and accepted phenomenon, especially in the United States.1 Meanwhile, as kidney transplant programs became established and began to expand, the proportion of living donor transplants decreased at the end of 1970s. With the increasing availability of dialysis, most centers discouraged transplantation from living donors, given that a cadaveric kidney provides an equal benefit to the recipients. In the last two decades, the results of transplantation have steadily improved and have been particularly good since cyclosporine (CyA) was added to the immunosuppressive regimen.
