It is a concrete...: Bladder stone is a concrete resulting from continual deposition on a debris or particle such as a stone passed into bladder from kidney or from a foreign body. Normally, such small particle should be passed through urethra, but for those with inability to empty bladder, such particles become the nidus to lay-by-layer form a concrete - stone, which can be removed surgically, & prevented by eliminat

Grow from nidus/seed: Which can be tiny stone formed in & kidney, mucus in bladder if enlarged with bowel or foreign body e.g. Indwelling catheter. Plus incomplete bladder emptying & urinary calcium, phosphate, uric acid etc come out of solution, attach to seed & stone enlarges.
