What causes urinary stones

Urinary tract stones are relatively common stones, including kidney stones, bladder stones, ureteral stones, etc. There are many causes of urinary tract stones, which are closely related to personal lifestyle habits, such as not liking to exercise, liking to drink, smoking, etc. In addition, different regions and drinking water conditions are also causes of urinary tract stones.

1. Urinary tract factors

Patients with prostatic hypertrophy have decreased urinary tract patency, increased residual urine volume, and a greater chance of bladder stone formation; congenital ureteral stenosis leads to hydronephrosis, which is prone to stone formation, and at the same time, stone obstruction of the urinary tract accelerates the growth of urethral stones; the vast majority of urethral stones come from stones in the bladder and kidneys.

2. Environmental factors

Natural environment - such as regional differences and climatic conditions. For example, in hot areas, excessive sweating can lead to higher urine concentrations, and the increase in calcium content in water makes urethral stones more likely to form. Social conditions: Excessive intake of animal protein causes more bladder stones in children; areas with abundant fruits and vegetables have more oxalate stones; abundant living materials increase the number of upper urinary tract stones; bladder stones are common in a few poor areas in Africa.

3. Individual factors and genetic factors

Some autosomal inherited renal tubular dysfunction and congenital enzyme deficiency are genetic diseases that are closely related to stone formation. The incidence of stone disease in the families of patients with stone disease is higher than that in the families of patients without stone disease. B. Diseases: Some diseases such as hyperthyroidism, hypercortisolism, long-term bed rest, osteolytic bone tumors, etc. may induce the formation of urethral stones. Other metabolic abnormalities, in addition to some metabolic abnormalities caused by congenital or acquired diseases, there are also some metabolic abnormalities whose causes are not very clear, such as idiopathic hypercalciuria, idiopathic hyperuricemia, etc.
