The main chemical compound found in human kidney stone is

The main chemical compound found in human kidney stones is [C] Calcium oxalate. These stones constitute the most prevalent type, forming when calcium combines with oxalate, a substance naturally found in many foods. When urine contains high levels of calcium and oxalate, they can crystallize, aggregating to form solid stones within the kidneys. Calcium oxalate stones vary in size and may cause significant discomfort and complications if they obstruct the urinary tract.

While other compounds like [A] Uric acid can also contribute to kidney stone formation, calcium oxalate stones are the most common. Although less frequent, stones composed of [B] Calcium carbonate or [D] Calcium sulphate may also occur, but their occurrence is comparatively rare compared to calcium oxalate stones, which are the predominant type encountered in clinical settings.
