More than 90% of transplanted kidneys function well for at least one year and the average lifespan of a transplanted organ is between 10 and 15 years.
Performing a transplant before dialysis starts can extend life expectancy after
transplant. Refrigeration of the donor kidney also offers significant improvements and is easy to do when kidneys are being donated by people who have died.
It was shown that refrigerated kidneys "start up" 40% better than unrefrigerated ones. A similar effect is also to be observed in the case of donor kidneys that have been perfused externally prior to being transplanted.
In the future, xenografts could also be an interesting alternative, that is to say tissue cells from two different species -- currently the scientific community is conducting studies with porcine islet cells.
