2016年7月28日 · Phosphate stones, HA or Br, can grow faster and larger than calcium oxalate ones. Calcium phosphate crystals invade kidney tissue – so called tubule plugs. Tissue damage is common, as is Nephrocalcinosis from plugging – often misdiagnosed as medullary sponge kidney. Kidney tissue damage is worse with Br than HA stones.

2024年3月14日 · Discover the common signs and symptoms of calcium phosphate kidney stones, such as pain in the lower back and frequent urination. Explore various treatment approaches, including lifestyle changes, medications, and surgical interventions. Stay informed and take steps to prevent the recurrence of calcium phosphate kidney stones.

2019年5月17日 · Calcium stones are the most common type of kidney stones, and can be either calcium oxalate or calcium phosphate. As mentioned, good hydration is important to prevent calcium stones. It may be surprising, but results of a randomized clinical trial show that people with calcium kidney stones should not cut back on dietary calcium.

2024年4月20日 · Most patients with nephrolithiasis (75%-85%) form calcium stones, most composed primarily of calcium oxalate (monohydrate or dihydrate) or calcium phosphate. The other main types include uric acid (8%-10%), struvite (calcium magnesium ammonium phosphate, 7%-8%), and cystine stones (1%-2%).

2019年4月15日 · Up to 75% of stones in pregnant women are composed of calcium phosphate, in contrast with other adults, in whom calcium oxalate stones are most common. 5 Diagnostic and treatment options...

2014年6月20日 · Calcium phosphate stone crystals form when calcium atoms combine with phosphoric instead of oxalic acid and produce the calcium phosphate kidney stone. Phosphoric acid is simply a phosphorus atom (shown as the ‘P’ in the line drawing to the left) with 4 oxygen atoms bonded to it.

Calcium phosphate stones, another kind of calcium stone, are much less common than calcium oxalate stones. For some people, calcium phosphate stones form as a result of a medical condition known as renal tubular acidosis.

2022年6月3日 · Some calcium phosphate stones are caused by overactive parathyroid glands, which are located on the four corners of your thyroid gland, just below your Adam's apple. When these glands produce too much parathyroid hormone (hyperparathyroidism), your calcium levels can become too high and kidney stones may form as a result.

2023年8月9日 · Approximately 80% of kidney stones are calcareous stones, the majority composed of calcium oxalate, with a small percentage made of calcium phosphate. The pathophysiological mechanisms for calcium oxalate stone formation are complex and include low urine volume, hypercalciuria, hypocitraturia, hyperoxaluria, and hyperuricosuria.

Calcium stones are the most common type of kidney stone caused by an excess of the essential mineral calcium. They can either occur in the form of calcium oxalate or calcium phosphate. If the calcium stone is made of calcium oxalate, the kidney stone is likely to be the result of diet, high Vitamin D levels, intestinal bypass surgery or a ...
