Kidney stone crystals, coloured scanning electron micrograph (SEM). Kidney stones are usually formed by the precipitation of the mineral salt calcium oxalate from the urine. The resulting hard stones (calculi) can cause severe pain, especially as they pass down the urinary tract. Large stones may need to be surgically removed or broken down with ultrasound therapy.
