If your bladder stones are causing painful symptoms, you should talk to your doctor. Without treatment, bladder stones can cause a number of long term urinary problems, including frequent urinary tract infections, chronic painful and frequent urination, and blockage of the urinary tract. Bladder stones irritate the inside of your bladder and raise your chances of contracting bladder cancer. Only your doctor can tell you if your bladder stones will pass without surgery. If your bladder stones are large, surgery may be your only option.
