What causes a kidney cyst?

ANSWER

The cause of simple kidney cysts is not fully understood, but they do not appear to be inherited. Being male is a risk factor, however, as is age: Almost half of all people age 50 or older have one or more simple cysts in the kidneys. The size of these cysts may also increase with age and may double over 10 years.
