Kidney transplantation is surgery to transplant a solid kidney from a living or deceased donor to a person whose kidneys are not functioning properly. The kidneys are two bean-shaped organs on either side of the spine below the ribs.
Each is the size of a fist. Its main task is to carry and excrete waste products, minerals, and body fluids in the blood through the production of urine.
When the kidney loses this filtering capacity, it increases the destruction of water and waste products in the body, increases the circulating pressure and causes kidney failure. Visceral nephropathy occurs when the kidneys lose about 90% of their normal working capacity.
