Kidney with calcium deposits and a partially formed stag horn calculus. Most calculi form by a combination of genetics and environmental factors. [2] Risk factors include high urine calcium levels, obesity, certain foods, some medications, calcium supplements, hyperparathyroidism, gout and not drinking enough fluids.
One of the principal causes of arterial stiffening with age is vascular calcification. Vascular calcification is the deposition of mineral in the form of calcium phosphate salts in the smooth muscle-rich medial layer of large arteries including the aorta. DNA damage, especially oxidative DNA damage, causes accelerated vascular calcification. [11]
Stones can cause disease by several mechanisms: [citation needed] Irritation of nearby tissues, causing pain, swelling, and inflammation; Obstruction of an opening or duct, interfering with normal flow and disrupting the function of the organ in question; Predisposition to infection (often due to disruption of normal flow)
Metastatic calcification can occur widely throughout the body but principally affects the interstitial tissues of the vasculature, kidneys, lungs, and gastric mucosa. For the latter three, acid secretions or rapid changes in pH levels contribute to the formation of salts.
Kidney showing circumscribed calcium deposits together with a partial stag horn calculus. Nephrocalcinosis , once known as Albright's calcinosis after Fuller Albright , is a term originally used to describe the deposition of poorly soluble calcium salts in the renal parenchyma due to hyperparathyroidism .
Calcinosis is the formation of calcium deposits in any soft tissue. [1] It is a rare condition that has many different causes. These range from infection and injury to systemic diseases like kidney failure.
Hodkinson and Pyrah proposed hypercalciuria as a calcium excretion of over 7.5 mmol in men and 6.25 mmol in women, every 24 hours, [4] but some argue that these values are too restrictive and ignore age, weight considerations, and renal function. Calcium excretion is negatively associated with age until the ages of 30–60, where calcium ...
On the other hand, CKD-MBD is defined as a systemic disorder of mineral and bone metabolism due to CKD manifested by either one or a combination of the following: 1) abnormalities of calcium, phosphorus, PTH, or vitamin D metabolism; 2) abnormalities in bone turnover, mineralization, volume, linear growth, or strength (renal osteodystrophy ...
