A bladder stone or cystolithiasis is a stone that is located in the bladder and gets stuck there. However, this is very rare as stones in the bladder are usually easily urinated. Bladder stones usually occur in patients who have a bladder probe for a long time, when crystals deposit around this probe.


In most cases bladder stones do not cause symptoms.
They are often too small to feel or cause other problems. When the stones are a bit bigger, they can make urination difficult. Pain and burning during urination are typical symptoms. Bladder stones can also cause or maintain a bladder infection.

If the stone is not too big, the urologist can remove it by means of a cystoscopy, ie through the urethra (endocystolithotripsy). Large stones may require abdominal surgery.
