Definition

Bladder stones are hard buildups of minerals that form in the urinary bladder.


Alternative Names

Stones - bladder; Urinary tract stones; Bladder calculi


Causes, incidence, and risk factors

Bladder stones are usually the result of another urologic problem, such as:

  • Bladder diverticulum
  • Enlarged prostate
  • Neurogenic bladder
  • Urinary tract infection

Approximately 95% of all bladder stones occur in men. Bladder stones are much less common than kidney stones.

Bladder stones may occur when urine in the bladder is concentrated and materials crystallize. Symptoms occur when the stone irritates the lining of the bladder or obstructs the flow of urine from the bladder.
