Kidney cysts are benign sacs of fluid that develop inside the kidneys. They are not the same as cysts that form with polycystic kidney disease, which is a genetic condition. The cause of simple kidney cysts is not known, and they are more common in older people. Simple kidney cysts may not cause symptoms. Occasionally, however, a kidney cyst can cause pain, infection or bleeding. In rare cases, simple kidney cysts can interfere with proper kidney function. It is also thought that simple kidney cysts can lead to high blood pressure.
