In developing nations, bladder stones are common in children — often because of dehydration, infection and a low-protein diet. In other parts of the world, bladder stones occur primarily in adults, especially in men age 30 and older.

Conditions that contribute to your risk of bladder stones include:

  • Bladder outlet obstruction. Bladder outlet obstruction refers to any condition that blocks the flow of urine from your bladder to the urethra, the tube that carries urine out of your body. Bladder outlet obstruction has many causes, but the most common is an enlarged prostate.
  • Neurogenic bladder. Stroke, spinal cord injuries, Parkinson's disease, diabetes, a herniated disk and a number of other problems can damage the nerves that control bladder function. Some people with neurogenic bladder may also have an enlarged prostate or other type of bladder outlet obstruction, which further increases the risk of stones.
