The reasons for the formation of urinary stones are mainly related to metabolic abnormalities, local factors, and the effects of some drugs.
1. Abnormal metabolism mainly includes the increase of urinary stone-forming substances: such as calcium, oxalic acid and other urinary discharges increase; and the change of urinary pH, may form stones in the urine, etc. Local factors include urinary tract obstruction, infectious diseases, etc. are factors that induce the formation of stones.
2. Local factors, including urinary tract obstruction and infectious diseases, are all factors that trigger the appearance of stones. Obstruction can lead to infection and stone formation, while stones can aggravate obstruction and infection.
3. Drugs that cause stones are mainly divided into two categories: one is that the concentration of such drugs in the urine is high while the solubility is low, such as amphotericin, etc.; the other category can induce stone formation, such as acetazolamide.
Patients with urinary tract stones can be assisted in determining the cause of the disease through relevant examinations and treated under the guidance of a doctor.
