Kidney stone fragments. Fragments of kidney stone removed from a patient using lithotripsy. Kidney stones are usually formed by the precipitation of the mineral salt calcium oxalate from the urine. The resulting hard,round stones (calculi) may cause severe pain,especially as they pass down the urinary tract. Large stones may need to be surgically removed or broken down using ultrasound therapy. Lithotripsy is a procedure that breaks down hardened masses such as kidney stones so that they may be removed from the body | |
