Some of the oxalate in urine is produced by the body. Calcium and oxalate in the diet play a part but are not the only factors that affect the formation of calcium oxalate stones. Dietary oxalate is found in many vegetables, fruits, and nuts. Calcium from bone may also play a role in kidney stone formation. Calcium phosphate: 10–20%
The term nephrocalcinosis is used to describe the deposition of both calcium oxalate and calcium phosphate. [1] It may cause acute kidney injury. It is now more commonly used to describe diffuse, fine, renal parenchymal calcification in radiology. [2] It is caused by multiple different conditions and is determined by progressive kidney dysfunction.
Cultural groups with diets that depend highly on fruits and vegetables high in calcium oxalate, such as those in Micronesia, reduce the level of it by boiling and cooking them. [4] [5] They are a constituent in 76% of human kidney stones. [6] Calcium oxalate is also found in beerstone, a scale that forms on containers used in breweries.
Calcium phosphate stones account for approximately 15% of kidney stone disease. Calcium phosphate stones tend to grow in alkaline urine, especially when Proteus bacteria are present. It is the most common type in pregnant women. [6] Calcium phosphate is the usual constitution of microcalcifications of the breast, particularly dystrophic ...
Hydroxyapatite (IMA name: hydroxylapatite [5]) (Hap, HAp, or HA) is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), often written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities. [6]
Struvite kidney stones are also known as triple phosphate stones (calcium magnesium ammonium phosphate), owing to the presence of carbonate apatite that precipitates to accompany struvite at high pH. [10] [11] [12] Struvite and carbonate apatite precipitate in alkaline urine, forming kidney stones.
Bladder stones may occur whenever the kidneys, bladder, or ureters become inflamed, which may occur when the urine becomes too concentrated or when the body becomes dehydrated. Minerals such as calcium and magnesium crystallize into the stones, which then can cause such symptoms as lower back or abdominal pain or difficulty with urination.
Whewellite / ˈ h juː ə l aɪ t / is a mineral, hydrated calcium oxalate, formula Ca C 2 O 4 ·H 2 O. [6] Because of its organic content it is thought to have an indirect biological origin; this hypothesis is supported by its presence in coal and sedimentary nodules. However, it has also been found in hydrothermal deposits where a biological ...
