A kidney transplant is the transfer of a healthy kidney from one person into the body of a person who has little or no kidney function.
The main role of the kidneys is to filter waste products from the blood and convert them to wee. If the kidneys lose this ability, waste products can build up, which is potentially life-threatening.
This loss of kidney function, known as end-stage chronic kidney disease or kidney failure, is the most common reason for needing a kidney transplant.
It’s possible to partially replicate the functions of the kidney using a blood filtering procedure known as dialysis. However, this can be inconvenient and time-consuming, so a kidney transplant is the treatment of choice for kidney failure whenever possible.
