Testing for renal cysts includes diagnostic imaging and kidney function tests, states Mayo Clinic. While it is unclear what causes kidney cysts, one theory suggests they develop when the surface layer of the kidneys weaken and forms a pouch or diverticulum.Continue Reading
Kidney cysts are pouches of fluid that form in the kidneys and may be associated with disorders that impair kidney function, states Mayo Clinic. Generally, only one cyst is present on the kidney’s surface, although multiple cysts may be present on one or both kidneys.
Simple cysts differ from polycystic kidney disease, a progressive disease that results in kidney failure, and often do not cause harm, adds to WebMD. Simple kidney cysts, which have been associated with high blood pressure, may cause pain in the side, back or abdomen; may become infected causing fever, chills and other signs of infection; and may impair kidney function, although kidney function impairment is rare.
In rare cases where a patient presents symptoms, treatment involves puncturing the cyst by inserting a long needle through the skin, draining the cyst. Treatment may also include filling the empty pouch with an alcohol solution that hardens the tissue and reduces chances of recurrence, according to WebMD.Learn more about Conditions & Diseases
