Paired kidney donations to expand the living donor pool: the Western Australian experience

•Falling numbers of deceased organ donors and longer kidney transplant waiting lists have increased the emphasis on live kidney donation to meet demand for kidney transplantation.•Several new strategies have been introduced to expand live donation beyond the classic direct donation. These include:•altruistic donation;•paired kidney exchange (PKE); and•altruistic donor chains programs.•Using incompatible donor–recipient pairs and altruistic donors, the Western Australian PKE program achieved nine successful kidney transplantations between October 2007 and November 2008. •If PKE were performed routinely in Australia, the rate of kidney transplants could increase by 7%–10%.
