The annual number of kidney transplantations in Finland is 150 to 200. Successful kidney transplantation improves the patient's quality of life and prognosis and is cost-effective as compared with dialytic therapy. Only a few per cent of transplantations are made from a living donor. Waiting times for kidney transplantations have become longer in the last few years. Whereas attempts should be made to better identify potential brain-dead organ donors in order to increase kidney transplantations, transplantations from living donors could also reduce the disproportion between the availability and the need of organs.
