Conclusion
At present, FURSL has been widely used in the treatment of upper urinary tract calculi. With high efficiency and low incidence of complications, this technology has become a reliable method for the treatment of small and medium stones in upper urinary tract. However, there are some limitations in the treatment of large stones and lower calyceal stones. Lower calyceal stones are an independent risk factor for the efficacy of FURSL. The shortcomings of this study are single center retrospective study, no control group, lack of long-term follow-up data. It still need the large sample and multi-center study to further verify the efficacy of FURSL in the treatment of upper urinary tract calculi.
