AB  - INTRODUCTION: To analyze the primary stone free rate (pSFR) of flexible 
      ureterorenoscopy (fURS) in the treatment of renal stones and to identify clinical 
      predictors for the primary freedom from renal stones. MATERIALS AND METHODS: Two 
      hundred and seventy five patients, who underwent fURS for kidney stones were 
      analyzed. RESULTS: Index stone size was 6 mm. The stone was located in the lower 
      calyx in 48%. Ureteral access sheath was used in 97%. Operation time was 35 min 
      and primary stone clearance was 83%. pSFR increased from 74% in 2012 to 83% in 
      2013 and 90% in 2014 (p = 0.001). Preoperative stenting, index stone size, 
      cumulative stone size, lithotripsy, ureteral access sheath and operation time 
      were significantly correlated with the pSFR by univariate analysis. Multivariate 
      regression analysis showed index stone size, cumulative stone size, ureteral 
      access sheath and operation time as independent parameters for pSFR. CONCLUSIONS: 
      fURS for kidney stones is safe with a high pSFR. Clinical parameters for pSFR are 
      stone size, use of ureteral access sheath and operation time. In future, the 
      effective use of fURS for the removal of kidney stones needs to be checked by 
      prospective randomized trials.
