The lithotripsy effect of uric acid stones is ideal, with a success rate close to 80-90%. However, those containing calcium oxalate may affect the lithotripsy effect. The recurrence rate of this kind of stone is about 50%~65%, and prevention by strictly following measures is very effective to control its recurrence. 1. Drink a lot of water: drink at least 2000ml (equivalent to a warm bottle) of water daily to ensure a daily urine volume of more than 2000ml. 2, moderate exercise: facilitate the discharge of tiny stones, but should prevent excessive exercise leading to dehydration resulting in urine concentration. 3, weight control: obesity is easy to lead to stone formation, obese people should reduce weight. 4.Limit purine: purine is the precursor substance of uric acid, therefore, purine-rich foods such as meat, fish and shrimp should be strictly limited to less than 150g per day; avoid eating animal offal; eat less soy products and mushrooms. 5.Preferred food: low purine food, such as rice, noodles, eggs, milk, vegetables, fruits, etc. are suitable. 6, avoid oxalic acid: high oxalic acid food mainly includes amaranth, spinach, rhubarb, mango, strawberry, sesame, cocoa, chocolate, tea, various nuts (chestnut, almond, walnut, etc.), should be avoided or eat less. 7, alkalize urine: uric acid stones are easily formed in acidic urine, simplify the urine is conducive to stone dissolution by itself, can often eat citrus fruits rich in potassium citrate (an alkalizing agent). 8, strict abstinence from alcohol: should not drink alcohol, alcohol can increase urinary lactic acid excretion and cause urine acidification, in addition, drinking beer can produce a large amount of uric acid in the urine, which will lead to the recurrence of stones. 9, regular physical examination: every six months should be routinely re-examined urinary ultrasound, blood uric acid and uric acid.
