Is ureteral stone partial big operation

Ureteral stones are too large, first need to do B ultrasound or CT examination. To understand the size of the stone, if the diameter of the ureteral stone exceeds 0.5cm, this has exceeded the diameter of the ureter, it is easy to get stuck in the ureteral stricture site, after conservative treatment, the possibility of excretion is not high. If conservative treatment fails, then surgery needs to be considered. If ureteral calculi are in the upper segment, laser extracorporeal lithotripsy can be used to make the stones smaller and discharged from the body. If the stones are in the middle and lower segments of the ureter, ureteroscopic lithotripsy can be used to remove stones from the body.
