|Normal and polycystic kidneys|
Polycystic kidney disease (PKD) is a disorder in which clusters of cysts develop primarily within your kidneys. Cysts are noncancerous round sacs containing water-like fluid.
Polycystic kidney disease isn't limited to your kidneys, although the kidneys usually are the most severely affected organs. The disease can cause cysts to develop in your liver and elsewhere in your body.
A common complication of polycystic kidney disease is high blood pressure. Kidney failure is another common problem for people with polycystic kidney disease.
Polycystic kidney disease varies greatly in its severity, and some complications are preventable. Lifestyle changes and medical treatments may help reduce damage to your kidneys from complications, such as high blood pressure.
