Renal cysts are sacs of fluid that form in the kidneys. Most of the time, they are simple kidney cysts, meaning they have a thin wall and only water-like fluid inside. They are fairly common in older people and typically do not cause any symptoms or harm.

The cause of renal cysts is not known, although age is a major risk factor. An estimated one-third of people older than age 70 have at least one simple renal cyst. It can be normal to have more than one simple cyst in each kidney, especially with increasing age.

In rare cases, renal cysts may require treatment due to infection, bleeding, or enlargement.

Since they rarely cause symptoms, renal cysts are most often found during imaging tests performed for other reasons. In such cases without any symptoms, simple renal cysts are usually left alone and do not need any further tests.
