Hello, extracorporeal lithotripsy is a common method to treat ureteral calculi and a small amount of kidney calculi. After lithotripsy, stones may not be excreted at once. Moreover, sometimes urinary calculi are easy to be complicated with urinary tract infection. So after you break the stone, there may be some pain or discomfort there. Drink more water in recent days. If the symptoms get worse, you should go to the hospital for reexamination, B-ultrasound, urine routine, understand the stone discharge and whether there is infection in the urinary tract, and then treat the symptoms. I wish you a speedy recovery and good health.
