ABSTRACT=Objective: This article explores the differences in the effectiveness and safety of the treatment of upper urinary calculi between single-use flexible ureteroscope (su-fURS) and reusable flexible ureteroscope (ru-fURS).
Methods: We systematically searched PubMed, Embase, Cochrane Library, Scopus database and CNKI databases within a period from the date of database establishment to November 2020. Stata 16 was used for calculation and statistical analyses.
Results: A total of 1020 patients were included in 7 studies. Statistical differences were only found 
in the Clavien–Dindo grade II postoperative complication (OR 0.47; 95% CI 0.23 to 0.98; P = 0.04).
No significant statistical differences were observed in operative time (OT), estimated blood loss (EBL),
length of hospital stay (LOS) and stone-free rate (SFR).
Conclusions: Our meta-analysis results demonstrate that su-fURS, compared with ru-fURS, has similar effectiveness and better security for treating upper urinary calculi.
