After stone fragmentation if the procedure is relatively successful, the pain will be relieved in about 1-2 days. If lithotripsy is unsuccessful and the stone does not pass down, it may cause the pain to recur or even last longer. When the stones are relatively small, extracorporeal lithotripsy can be chosen as a treatment for the stones. Extracorporeal lithotripsy is a spacer type of treatment, the effect of lithotripsy will be worse compared to surgery, so too large stones are not suitable for extracorporeal lithotripsy. Generally less than 2cm kidney stones, or less than 1.2cm ureteral stones, you can try extracorporeal shock wave lithotripsy, which has the potential to break up the stones.
