Pain after lithotripsy may be caused by poor lithotripsy effect, local injury, infection and other factors. 1. Poor lithotripsy effect: After lithotripsy, the effect of lithotripsy is not ideal, and there are still large diameter stones, which may cause damage to the urinary tract tissues when they are discharged, and then there will still be painful symptoms. 2. Localized damage: After lithotripsy, the process of discharging the stone may cause localized damage, and the pain will still exist, but the pain symptoms are mild, and the pain symptoms may gradually improve after the stone is completely discharged. 3. Infection: Infection caused by the lack of proper care after lithotripsy will lead to local pain, which may be accompanied by weakness, fever, hematuria and other abnormal manifestations. To summarize, if there is still pain after stone crushing, it is recommended to go to the doctor for review, to clarify the specific causes and to carry out timely treatment.
