ANATOMY

Detailed explanation-1: -Most kidney stones are calcium stones, usually in the form of calcium oxalate. Oxalate is a substance made daily by your liver or absorbed from your diet. Certain fruits and vegetables, as well as nuts and chocolate, have high oxalate content.

Detailed explanation-2: -Up to 75 percent of all kidney stones are composed primarily of calcium. Stones can also be made up of uric acid (a normal waste product), cystine (a protein building block), or struvite (a phosphate mineral). Stones form when there is more of the compound in the urine than can be dissolved.

Detailed explanation-3: -The stone-forming chemicals are calcium, oxalate, urate, cystine, xanthine, and phosphate. After it is formed, the stone may stay in the kidney or travel down the urinary tract into the ureter.

Detailed explanation-4: -When fat is not absorbed the right way, the fat binds to calcium and leaves oxalate behind. The oxalate is then absorbed and taken to the kidney, where it can form stones.
