Why do kidney stones

Kidney disease - a chronic disease in which there is an infringement of metabolic processes in the body, which leads to local changes in the kidney with the formation in them (in their own kidney tissue in the calyx and pelvis) rocks formed from the salt and organic compounds of urine.

Kidney stones are found everywhere, but the disease is spread unevenly. The relatively low incidence observed in some areas of North Africa and elsewhere. Areas with frequent morbidity are located in the Middle East, India, China and Latin America.

The chemical composition and structure of stones depends largely on the reasons for their education. Thus, in violation of purine metabolism may form uric acid stones (from uric acid), and metabolic oxalate - oxalate. Phosphate stones occur mainly in the breach of phosphorus-calcium metabolism and the presence of urinary tract infections, causing alkaline urine.

Violation of phosphorus-calcium metabolism may occur with an increase in parathyroid gland function, such as prostate adenoma. Under the action of parathyroid hormone in the blood appears large amounts of calcium, but reduced the amount of phosphorus. Many of calcium appears in urine, one of them and form stones.

When infection of the urinary tract the urine becomes alkaline in nature, blood circulation in small vessels of the kidneys. Due to the products of inflammation increases the viscosity of urine. In a viscous alkaline phosphates easily precipitate and form stones.
