Kidney stone. Illustration of a kidney (semi-transparent view) with a kidney stone (green and yellow,lower centre). 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. This kidney stone is in the lower part of the kidney (lower pole) in a major calyx. | |
