Can bladder stones cause overactive bladder?

Overactive bladder may develop as the result of underlying physical problems or changes, including bladder stones. These stones are masses of minerals that form in the bladder. They can develop when urine in the bladder becomes concentrated. The symptoms can range from abdominal pain to bloody urine. Not all bladder stones cause symptoms. If left untreated, these stones can cause infections and other complications. Sometimes they can pass out of the body on their own. However, they may need to be removed by a doctor.
