After extracorporeal lithotripsy, kidney stones and ureteral stones are currently allowed to be drained by the patients themselves, and the doctors will instruct the patients to drink more water and exercise more, and nothing else. There is a new treatment method called posture-assisted lithotripsy. The normal person is standing, head high and feet low, the upper renal calyces stones are easier to discharge under the action of gravity and urine flow, but the lower renal calyces stones need to put a slope to discharge, so it is more difficult.
