Kidneys are two reddish-brown organs that are shaped like beans and are found in vertebrates. They are positioned on the right and left side of the retroperitoneal space. Kidney disease is a condition in which the kidneys get damaged. It often leads to kidney dysfunction to some extent and might become the reason for kidney failure, which results in complete damage of kidneys and their function. Kidney failure is called the final stage of kidney disease in which kidney transplant or dialysis is the only way to treat the damage.
