RESUMEN
Since its establishment in 2008, the National Kidney Registry has facilitated 213 kidney transplants between unrelated living donors and recipients at 28 transplant centers. Rapid innovations in matching strategies, advanced computer technologies, good communication and an evolving understanding of the processes at participating transplant centers and histocompatibility laboratories are among the factors driving the success of the NKR. Virtual cross match accuracy has improved from 43% to 91% as a result of changes to the HLA typing requirements for potential donors and improved mechanisms to list unacceptable HLA antigens for sensitized patients. A uniform financial agreement among participating centers eliminated a major roadblock to facilitate unbalanced donor kidney exchanges among centers. The NKR transplanted 64% of the patients registered since 2008 and the average waiting time for those transplanted in 2010 was 11 months.
