The UK body NHS Blood and Transplant (NHSBT), for example, informs us that the risk of postoperative death (to the donor) is about one in 3,000. There is also a small risk (less than 1%) of minor complications (such as chest, wound, or urine infections). As regards long-term health risks, NHSBT claims that there is no long-term effect on the health of the donor or on his/her remaining kidney, and that donors are at no greater risk of developing kidney failure after donating than anyone in the general population. So, while there are some not completely insignificant risks to consider, arguably these are tolerable compared to both the risks to the prospective recipient of not receiving the kidney, and the financial benefit to the donor, provided that the level of reward is set at a suitably high level.
