A living-donor transplant is a surgical procedure to remove an organ or portion of an organ from a living person and place it in another person whose organ is no longer functioning properly.
The popularity of living-organ donation has increased dramatically in recent years as an alternative to deceased-organ donation due to the growing need for organs for transplantation and shortage of available deceased-donor organs. More than 6,000 living-organ donations are reported each year in the United States.
Living-kidney donation is the most common type of living-donor transplant. Individuals can donate one of their two kidneys, and the remaining kidney is able to perform the necessary functions. Living donors can also donate a portion of their liver, and the remaining liver regenerates, grows back to nearly its original size and performs its normal function.
