Bladder Stones

Bladder Stones Symptoms and Causes

Bladder stones are small, hard stones made of calcium or uric acid that form in the urinary bladder. They often form when urine stagnates (urinary stasis) in the bladder because of poor bladder emptying.

Common symptoms of bladder stones are:

  • Abdominal pain, pressure
  • Abnormally colored or dark-colored urine
  • Blood in the urine
  • Difficulty urinating
  • Frequent urge to urinate
  • Inability to urinate except in certain positions
  • Interruption of the urine stream
  • Pain, discomfort in the penis
  • Urinary tract infection 
  • Incontinence

Common causes of bladder stones are:

  • Bladder diverticulum (small, bulging pouches in the bladder wall that may be congenital or acquired)
  • Enlarged prostate
  • Neurogenic bladder (a urinary problem in which the bladder does not empty)
  • Urinary tract infection
