What causes kidney stones?

Kidney stones are a common disease in urology. The cause of their formation is a complex process involving multiple factors, such as non-disease factors, dietary factors, metabolic abnormalities, drug factors, disease factors, urinary tract infection, urinary tract obstruction, etc. The details are as follows:

1. Non-disease factors

1. Dietary factors: Excessive intake of spinach, beans, grapes, potatoes, plums, bamboo shoots and other foods contain more oxalic acid, which will increase the concentration of oxalic acid in urine. At the same time, excessive fat intake will reduce the amount of calcium that can be combined in the intestine, thereby increasing the absorption of oxalate and increasing the risk of stone formation.

2. Metabolic abnormalities: Common components in urine that can form stones include calcium, oxalic acid, uric acid and cystine. Any physiological disorder that causes abnormalities in these components may cause stone formation and promote stone growth. For example, if the concentration of calcium, oxalic acid, uric acid and other components in urine is too high, stones are easily formed.

3. Drug factors: Long-term use of certain drugs, such as triamterene, silicates and sulfonamides, may produce components that are prone to stone formation during drug metabolism, thereby increasing the risk of kidney stones.

2. Disease Factors

1. Urinary tract infection: When the urinary tract is infected, bacteria may decompose urea into ammonia, making the urine alkaline, which is conducive to the deposition of phosphates and carbonates and the formation of stones.

2. Urinary tract obstruction: Urinary tract obstruction may cause urine congestion, making it easier for crystalline substances in the urine to deposit and form stones.

Note: In order to prevent the occurrence of kidney stones, you should pay attention to a reasonable diet, avoid spicy and greasy foods, and avoid eating foods high in oxalic acid. At the same time, you can do appropriate exercise to enhance your physical fitness and disease resistance. If you have any symptoms of discomfort, you can seek medical help in time.
