Bilateral kidney sand-like stones should be treated with lithotripsy according to the size and nature of the stones and other reasons. Specific treatments may include medication, extracorporeal shock wave lithotripsy, percutaneous nephrolithotripsy and so on. 1. If the stone is less than 0.6cm, the surface is smooth and there is no obstruction in the urinary tract below the stone, drug treatment can be used. For example, uric acid stones can be treated with potassium sodium citrate or oral sodium bicarbonate, etc. Normally, you can drink more water to promote stone excretion. 2. If the stone is 0.6cm~2cm, extracorporeal shock wave lithotripsy can be used for treatment. The main method is to use high-energy shock wave to crush the stone under ultrasound localization, so as to make it cracked. Contraindications include distal obstruction of the stone, aortic aneurysm, and excessive obesity. 3. Usually, sand-like stones in both kidneys can be discharged through conservative treatment. Some patients are unable to discharge the stones, and the stones are deposited and grow, so percutaneous nephrolithotripsy is feasible when necessary, which is generally applicable to ≥2cm renal stones, complete or incomplete dehiscence stones, and failure of extracorporeal shock wave lithotripsy. Contraindications include excessive obesity, patients with severe coagulation disorders, and so on. If you have double kidney sand-like stones, you should consult a regular hospital for specific treatment in time and under the guidance of a doctor.
