Urinary stones are mostly seen in men. The cause is not well understood, but is associated with foreign bodies, obstruction, infection, nutritional disorders, endocrine and metabolic disorders and prolonged bed rest. Urinary stones can cause severe pain and hematuria. They can also cause fever if secondary infection occurs. Long-term obstruction of stones can cause fluid retention and functional impairment in the urinary tract above the obstruction site, so they should be actively treated. Caution: 1. Urinary tract stones should be actively treated, otherwise recurrent colic and infection may occur, and even cause urinary tract fluid accumulation, leading to renal hypoperfusion. 2.Urinary tract stones with a diameter of about 0.5 cm may be excreted by drinking more water to increase urine volume, or by increasing ureteral peristalsis with antispasmodics and by applying diuretic and laxative herbs. 3.Single kidney stones with a diameter of 1.5 cm or less can be treated by extracorporeal shock wave lithotripsy. 4. Kidney stones larger than 1.5 cm in diameter, ureteral stones with obstruction causing hydronephrosis, and stones with combined infection should be actively considered for surgical treatment such as laser lithotripsy. 5. Drink more water, which should exceed 2000 ml per day (equivalent to the amount of 4 bottles of saline bottles used for hospital infusion). Avoid drinking high hardness water, and drink magnetized water. Eat more low-calcium diet and less dairy products, as they contain more calcium. Eat less spinach, beets, cocoa, black tea, chili peppers, nuts, animal offal (liver, brain, kidney), mushrooms and fish. Eat less sugar because the concentration of calcium ions in the urine, oxalic acid and the acidity of the urine increase after eating sugar.
