Kidney stones are formed by small crystals that clump together in the kidney.
These can vary greatly in size or composition. When such a stone detaches from the kidney, acute renal colic may occur. A kidney stone is usually small enough to pass through the urinary tract. Sometimes the kidney stone is too large or too irregular in shape, and may become lodged in the urinary tract.
Please contact your treating doctor for more information.
Your treating doctor will discuss the treatment options with you.
