Kidney stones are chunks of material, usually calcium compounds, that form in the kidney and can become lodged in the ureter, which leads from the kidneys to the bladder. Once â¦ a stone passes, or is dislodged or broken up, it can be captured from the urine by a filter cone, and returned to a urologist for examination.
