RT Journal A1 Blumberg JM T1 THe perfect match JF JAMA JO JAMA YR 2011 FD November 23 VO 306 IS 20 SP 2197 OP 2198 DO 10.1001/jama.2011.1710 UL http://dx.doi.org/10.1001/jama.2011.1710 AB The first successful kidney transplant was indeed a perfect match, performed in 1954 by Dr Joseph Murray at the Peter Bent Brigham Hospital between identical twins Richard and Ronald Herrick. The United Network for Organ Sharing (UNOS) and the Organ Procurement and Transplantation Network (OPTN) did not exist at that time; matching of the twin donor-recipient pair was confirmed when a small donor skin graft from Ronald was not rejected by Richard. And while the surgical principles of kidney transplantation have barely changed since that historic December day, the way in which we match recipients with their eventual donor has become very complicated.
