What are bladder stones?
Bladder stones, more correctly called uroliths, or cystic calculi are rock-like collections of minerals that form in the urinary bladder. They may occur as a large, single stone or as collections of stones the size of large grains of sand or gravel.
Are these the same as gall stones or kidney stones?
No. Gall stones are in the gall bladder, and kidney stones are in the kidney. Although the kidneys and urinary bladder are both part of the urinary system, kidney stones are usually unrelated to bladder stones.
