Understanding Bladder Stones
Bladder stones are small deposits of crystals made from minerals and proteins that form in the urine. They may form when a small amount of urine stays in your bladder after urinating. Urine contains minerals, such as calcium oxalate and uric acid, that can build up and harden, forming stones.
Bladder stones can vary in size and shape. They are more likely to occur in men.
What causes bladder stones?
An enlarged prostate in men is the most common cause of bladder stones. The prostate is a small gland located near the urethra. The urethra is the tube that empties urine from the body. As men age, the prostate tends to become larger, and it pushes against the urethra. That may cause the bladder to not empty completely.
Other possible causes of bladder stones are:
-
Diet problems, such as a lack of water (dehydration)
-
Urinary tract infection
-
Pelvic organ prolapse in women
-
Injury to the spinal cord that affects how you urinate
-
Bladder surgery
-
Foreign object in the bladder, such as stitches from a medical procedure or a catheter
Symptoms of bladder stones
Some bladder stones cause no problems. But if they do, you may have these symptoms:
Treatment for bladder stones
In some cases, you may not need any treatment for a bladder stone. It may eventually pass out of your body when you use the toilet. For larger stones, treatment may include:
-
Changes in diet. Drinking more water each day may help the stone leave your body. You may feel some pain when the stone passes. You may also need to cut back on salt and fat to stop more stones from forming.
-
Surgery. Several different procedures are available to treat bladder stones. Some stones may be removed through the urethra with a small tube with a camera on it (cystoscope). A healthcare provider may use the scope to break up the stone with lasers or shock waves. Large stones may be removed through a cut near the pelvis.
