      management: a pooled analysis of 772 patients.

AB  - Flexible ureteroscopy is a common therapy for patients with renal calculi. In 
      recent years, the prevalence of single-use flexible ureteroscope (FURS) use has 
      been on the rise. Thus, several trials have been conducted to compare the 
      efficacy between single-use and reusable FURS. The aim of this meta-analysis was 
      to systematically assess the effectiveness and safety of single-use vs. reusable 
      FURS in treating renal stones. PubMed, Web of Science, Cochrane Library and 
      EMBASE were researched to identify relevant studies up to September 2019. Article 
      selection was performed through the search strategy based on Preferred Reporting 
      Items for Systematic Reviews and Meta-Analyses criteria. The Newcastle-Ottawa 
      Scale was applied to assess the methodological quality of non-randomized 
      controlled trials, and the methodological quality of randomized controlled trials 
      was evaluated using the Jadad scale. A total of five studies with 772 patients 
      were included in the meta-analysis, including two randomized controlled trials, 
      two single-centre prospective studies, and one prospective case-control trial. 
      The pooled results showed that single-use FURS was associated with a higher 
      stone-free rate (SFR) (OR: 1.50; 95% CI, 1.06-2.12; P=0.02) than reusable FURS. A 
      significant difference was noted in operative time, and single-use FURS was 
      associated with a longer operative duration (MD: 7.39 min; 95% CI, 1.75-13.03; 
      P=0.01). No significant difference was noted in perioperative complications (OR: 
      0.97; 95% CI, 0.56-1.70; P=0.92). Subgroup analysis showed no significant 
      difference in urinary tract infection (OR: 0.80; 95% CI, 0.44-1.46; P=0.46), 
      stent migration (OR: 0.56; 95% CI, 0.19-1.65; P=0.30) or acute kidney injury (OR: 
      0.76; 95% CI, 0.16-3.57; P=0.73). Single-use FURS is an effective and safe 
      alternative to reusable FURS for the management of renal stones.
