What is a kidney cyst?
Kidney cysts are round pouches of fluid that form on or in the kidneys.
Kidney cysts can be associated with serious disorders that may impair kidney function. But more commonly, kidney cysts are a type called simple kidney cysts — noncancerous cysts that rarely cause complications.
It's not clear what causes simple kidney cysts.
Simple kidney cysts are often detected during an imaging test performed for another condition.
Simple kidney cysts that don't cause signs or symptoms usually don't require treatment. Surgical intervention is required in clinical cases where the renal cyst is large, protruding from neighboring organs, there is a risk of bleeding or rupture.
Simple kidney cysts typically don't cause signs or symptoms. If a simple kidney cyst grows large enough, symptoms may include:
- Dull pain in your back or side
- Fever
- Upper abdominal pain
The risk of having simple kidney cysts increases as you get older, though they can occur at any age. Simple kidney cysts are more common in men.
