Cysts (spherical, thin-walled fluid-filled sacs) may develop within the tissues of the kidneys singly or in groups. Single kidney cysts are not a health risk and are common after age 50. While cancer or infection may develop within one cyst, such complications are very rare.However, polycystic kidney disease, a common inherited disorder, may lead to the formation of hundreds of cysts, abnormally enlarged kidneys, and eventual kidney failure.
Asymptomatic cases may benefit from modest dietary changes as well as prescription medications, in particular ACE inhibitors or ARBs (angiotensin receptor blockers). Antibiotics may be prescribed to treat associated urinary tract infections. Antihypertensive drugs are prescribed to treat associated high blood pressure. A kidney transplant is an alternative to dialysis in cases of kidney failure.
