A kidney transplant is a surgery undertaken to replace ones kidney with another kidney from a healthy person who is often called a donor. The donor could be either a person alive or a deceased person. The deceased person will be the one who recently passed away. Tests are to be taken to find out if the kidney of the donor matches the recipient’s blood type or tissue type to avoid rejection. Kidney transplant usually lasts for 3 hours. The donor’s kidney is placed in the lower abdomen of the recipient. Blood vessels from the donor’s kidney are connected to arteries and veins of the recipient body, and the ureter from the donor kidney is connected to the recipient's bladder. Blood will be then able to flow through the donor kidney, and the kidney will begin to filter and remove wastes besides producing urine. There are several kinds of kidney diseases which can lead to end-stage renal disease (ESRD), a condition in which the kidneys fail to work normally. People with kidney failure need to receive dialysis or a kidney transplant.
