The first reported successful kidney transplantation occurred in 1954, between twins. Since then, organ donation and transplantation has become less a medical marvel than a common expectation of patients with a variety of diseases resulting in organ failure. Those expectations have caused demand for organs to skyrocket far beyond available supply, fueling an organ shortage and resulting in over 60,000 patients on transplant waiting lists. In this special issue, our contributors attempt to shed new light on some of the many old ethical questions raised by transplant in the contemporary context of extreme scarcity.
