 The primary ethical question raised by living donation is to do with the risk of having an organ taken. Having an organ taken imposes risks of death, disease, and discomfort from trauma, infection, the use of a general anaesthetic, and the loss of all or part of an organ (although the liver will usually regenerate, replacing the part removed). These risks are not negligible. However, the risk of death is not enormous. Focusing on the kidney, the most frequently donated organ and the safest to take from live donors, it has been estimated that the risk of death from kidney retrieval is 1/3000. There appears to be no difference between healthy screened living kidney donors and the general population in long-term survival and the risk of kidney failure. (Ibrahim et al. 2009). That said, the general population is less healthy on average than the healthy screened living donors, who do in fact undergo some extra risk of long-term renal failure as a result of one kidney being removed (Grams et al. 2016).
