About Kidneys and Transplantation
Your kidneys are twin organs located in the back on either side of the spine, protected by the lower ribs. Each kidney is about the size of a fist and weighs approximately five ounces. Although most people have two kidneys, odds are that one in every 500 healthy babies is born with just one. You need only one healthy kidney to live normally.
