There are two causes of bladder stones:

First, it may be due to kidney stones that move down through the ureter and form bladder stones.

Second, it is mainly due to obstructions in the urinary tract, such as an enlarged prostate, which causes the patient's bladder to not completely empty the urine each time, leading to urinary retention. Over time, stones can develop in the bladder and thus form bladder stones.

The treatment of bladder stones depends on the size of the stone. You can visit the urology department of your local hospital for examination and treatment.
