AB  - PURPOSE: This study aimed to investigate the effect of preoperative stenting 
      (POS) on the perioperative outcomes of flexible ureterorenoscopy (fURS). 
      MATERIALS AND METHODS: A systematic review and meta-analysis was conducted based 
      on the PRISMA statement. From the initially retrieved 609 reports, we excluded 
      the ineligible studies at 2 stages. We only included studies that contained fURS 
      patients with and without POS in the same report. Data of patients who underwent 
      semirigid ureteroscope only were excluded from the analysis. The Newcastle-Ottawa 
      Scale (NOS) system was applied for risk of bias assessment. RESULTS: A total of 
      20 studies including 5,852 patients were involved. 48.5% of the patients had 
      preoperative stent. Stone-free rate was significantly higher with prestenting; 
      odds ratio (OR) was 1.98 (95% CI: 1.51-2.58) (Z = 5.02; p = 0.00001). It also 
      displayed tendency toward lower complications; OR was 0.74 (95% CI: 0.52-1.05) (Z 
      = 1.67; p = 0.09). POS significantly increased the use of ureteral access sheath; 
      OR was 1.49 (95% CI: 1.05-2.13) (Z = 2.22; p = 0.03). Risk of bias assessment 
      showed 13 and 7 studies with low and moderate risk, respectively. CONCLUSIONS: 
      POS clearly improves the stone-free rates after fURS. It might reduce the 
      complications, especially ureteral injury. These findings might help solve the 
      current debate and can be useful for urologists during patient counselling for a 
      proper decision-making.
