Abstract
Altruistic kidney donation to a stranger can initiate a chain of transplants, significantly increasing the cumulative years of life saved across multiple recipients through paired exchanges. While end-stage renal disease necessitates dialysis—a procedure providing only 10% of normal kidney function with a high five-year mortality rate—transplantation extends life expectancy by approximately a decade and substantially restores quality of life. The surgical risks for living donors are statistically low, with mortality rates between 1.3 and 3.1 per 10,000 and minimal long-term impact on life expectancy. The donation process requires several months of psychological and medical screening, culminating in a laparoscopic nephrectomy. Post-operative recovery involves manageable pain, primarily associated with carbon dioxide insufflation used during surgery, and a typical return to baseline health within several weeks. Financial barriers for donors are often mitigated by Medicare coverage or assistance programs, further lowering the personal cost. Given the asymmetry between the modest, temporary physical costs to the donor and the substantial life-saving benefits for the recipient, non-directed kidney donation represents a highly efficient moral and practical intervention to address the critical organ shortage. – AI-generated abstract.
