After lithotripsy, the abdomen keeps falling and swelling, considering that it may be caused by the stone moving downward. The effect of ureteral stone lithotripsy mainly depends on the size and hardness of the stone, especially the hardness of the stone. The higher the calcium content of the stone, the greater its hardness, the hardness of the uric acid stone is on the small side, the hardness of the stone, the small size of the stone, the lithotripsy effect is relatively good. The purpose of extracorporeal lithotripsy is to break up the stone. A stone that is broken up well will become smaller in size or break up into several pieces, which makes it easier for the stone to move downward. For example, if the stone is in the upper or middle part of the ureter, the ureteral stone will move downward after lithotripsy, especially to the end of the ureter and the lower part of the ureter, it will be easy to have abdominal swelling and even pain. At this time, you can take anti-inflammatory drugs, lithotripsy drugs and drugs to dilate the ureter, drink plenty of water, and then follow the doctor’s instructions to go to the hospital in time for review.
