Here's a breakdown:
* Formation: These stones form when minerals in the urine crystallize and clump together.
* Location: They reside within the bladder itself, the hollow organ where urine collects before being expelled from the body.
* Contrast with Kidney Stones: Kidney stones, which are much more common, form in the kidneys, where urine is produced. They can pass through the ureters (tubes connecting kidneys to bladder) and sometimes become lodged in the bladder, but they don't originate there.
It's important to note that while bladder stones form in the bladder, they can be caused by factors related to other parts of the urinary tract, like the kidneys. For instance, a kidney stone passing through the bladder can contribute to the formation of a bladder stone.
