How do kidney stones form in urine?
So long as the membrane covers it stones cannot form. But where the stone grew that membrane gave way. Urine bathed the exposed plaque and minerals from that urine formed the initial hydroxyapatite binding site that shows up at the bottom of the stone in the right hand panel of the picture.
What is a kidney stone?
A kidney stone is a hard object that is made from chemicals in the urine. There are four types of kidney stones: calcium oxalate, uric acid, struvite, and cystine. A kidney stone may be treated with shockwave lithotripsy, uteroscopy, percutaneous nephrolithomy or nephrolithotripsy.
What are the chemicals that form kidney stones?
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. Sometimes, tiny stones move out of the body in the urine without causing too much pain.
What factors affect the development of kidney stones?
Other important factors that affect the development of kidney stones include the amountof urine a person makes, with lower volumes leading to more concentrated urine, and the presence of slowed drainage, which can make it easier for crystals to gather and combine.
