The condition is inborn, even though it tends not to show up until age 20--40 or later.

The name can be a little misleading, since the kidney tissue doesn't really look 'spongy'; but the collecting tubules inside the kidney are dilated and therefore don't behave normally.

Fortunately is almost never progresses to renal failure; it's more a matter of managing potential infection and stones. I'm not really sure what the current practice for managing stones is; you need to ask the doctor about that.
