The study results showed that comparing with extracorporeal lithotripsy, ureteroscopy with a laser lithotripsy is a more effective and quicker treatment method when seeking to reach a stone free rate in the upper part of the ureter. When performing ureteroscopy with a laser lithotripsy the size of the stone does not influence the treatment results. The localization of the stone at the level of the 3rd lumbar vertebrae is related to its high possibility of migrating to the kidney, so, seeking to completely remove the stone after one operation, it is necessary to prepare a more complex surgical equipment in advance.
