A cyst is a fluid-filled sac. You may get simple kidney cysts as you age; they are usually harmless. There are also some diseases which cause kidney cysts. One type is polycystic kidney disease (PKD). It runs in families. In PKD, many cysts grow in the kidneys. This can enlarge the kidneys and make them work poorly. About half of people with the most common type of PKD end up with kidney failure. PKD also causes cysts in other parts of the body, such as the liver.
In most cases, simple kidney cysts do not cause symptoms and usually do not require treatment. However, in some cases simple kidney cysts can grow large enough and cause a dull pain in a person's back, side or upper abdomen. These cysts can also get infected, causing pain, fever and tenderness. They can burst, also causing pain. Simple kidney cysts rarely harm kidneys or impair their ability to function.
