There is no authoritative data to show whether the localization of lower and middle ureteral stones with extracorporeal shock wave lithotripsy is accurate or not, but some studies have shown that if the diameter of the stone is small, the localization of the stone by extracorporeal shock wave lithotripsy is not allowed, and if the diameter of the stone is large, the localization of the stone by extracorporeal shock wave lithotripsy is more accurate. If the stone diameter is small, the extracorporeal shock wave lithotripsy machine cannot locate the stone accurately. If the diameter of the stones in the lower and middle part of the ureter is large, the extracorporeal shock wave lithotripsy machine can locate the stones more accurately. Extracorporeal Shock Wave Lithotripsy is not recommended when the diameter of the stones in the lower and middle ureter is too small to be localized accurately. If the diameter of the stone in the lower and middle ureter is relatively large, it can be treated by extracorporeal shock wave lithotripsy. In addition, patients should drink a lot of water and can exercise properly every day.
