I. Recommendations 1. For infants and young children, asymptomatic renal calcium stones of 0.5 cm or more, treatment with Chinese medicine alone is a long course and should not be adhered to; the use of combined Chinese and Western medicine therapy with postural drainage should have better efficacy. On X-ray urographic film, the positive stones shown are usually those with high calcium content, which need to be differentiated from renal parenchymal calcification in medical imaging. In the case of the latter, no special treatment is needed and regular review is sufficient. 2. For asymptomatic 0.7CM*0.4CM renal calcium stones in young children, extracorporeal lithotripsy, lithotripsy, lithotripsy and lithotripsy with Chinese and Western drugs can be used, together with specific body positions to gently tap the kidney area to promote stone discharge. Surgical treatment is not considered. Regular ultrasound follow-up review. Taking Chinese medicine has certain effect of lithotripsy and lithotripsy, but all cannot be treated without taking comprehensive measures. Measures to prevent kidney stones in infants: 1. Drink water. Parents usually prevent infant kidney stones, you can give children to drink more water, eat more alkaline food, such as vegetables, fruits, etc., to prevent the formation of kidney stones is very good. 2, the right amount of calcium, one year old before the baby can not be supplemented with more than 500 mg of calcium a day, too blind unilateral calcium supplementation will cause infant kidney stones and osteosclerosis, hampering the growth and development of bones later. Calcium carbonate is absorbed through the intestine, there is a certain amount of human absorption, can not let the child eat more, eat more, can not be absorbed, if caused by precipitation, easy to cause kidney stones. 3, pay attention to the consumption of cod liver oil: cod liver oil is rich in vitamin D, has the function of promoting intestinal membrane absorption of calcium and phosphorus, suddenly increase the excretion of calcium and phosphorus in the urine, is bound to produce precipitation, easy to form stones. In addition, do not let your child hold urine, because holding urine is likely to cause urine concentration and increase the incidence of stones.
