Ureteral stone: It is recommended to prefer extracorporeal shock wave lithotripsy treatment, extracorporeal shock wave can break the stone in the body, but if long-term retention or lithotripsy treatment is ineffective, ureteroscopy should be used for lithotripsy, and the ureteral blockage can be recovered after the stone is removed. 2. Ureteral tumor: tumor growth, infiltration can block the lower part of the ureter, need to perform ureteral tumor resection. 3. Inflammatory ureteral stenosis: if the stenosis is caused by ureteritis, the primary disease should be treated in time, and ureteral resection of stenotic segment should be performed if necessary.
