A kidney transplant is an operation to transfer a healthy kidney from one person (either a living donor with two healthy kidneys or a person who has recently died) to another person who has little or no kidney function. For more information about the kidneys, see also What do kidneys do? and the separate leaflet called Chronic kidney disease.
