Kidney stones in babies may be due to drinking too little water. Treatment depends on the size of the stones, which can be treated by conservative treatment and medication. First of all, you can let the baby drink more water, appropriate activities, according to the type of stone and the pH of urine to adjust the diet structure, to promote the discharge of stones out of the body. The pH of urine can also be adjusted by medication such as oral baking soda or 10% potassium citrate, and observation should be made to adjust the dosage. When the stone is less than 5mm, conservative treatment and medication can be used to promote the expulsion of the stone from the body. If the stone is larger than 5mm, the baby is too small for extracorporeal shock wave, so it should be closely observed and treated conservatively by regulating the pH of urine and promoting urination. If the stone is bigger, it can be removed by ureteroscopy. In daily life should pay attention to the baby’s diet, drink more water, appropriate exercise, pay attention to nutrition, to prevent the baby from developing kidney stones. Once kidney stones appear, you should go to the hospital immediately.
