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 only your kidneys, although the kidneys usually are the most severely affected organs. The disease can cause cysts to develop elsewhere in your body.

The greatest risk for people with polycystic kidney disease is developing high blood pressure. Kidney failure also is common with polycystic kidney disease.

Polycystic kidney disease varies greatly in its severity, and some complications are preventable. Regular checkups can lead to treatments to reduce damage to your kidneys from complications, such as high blood pressure.
