 note = {Introduction: This study aimed to examine the efficacy of intra-institutional standardization of fluoroscopy use to reduce X-ray exposure and identify factors that predict reduced fluoroscopy time.
　Methods: We recruited 231 patients who underwent ureteroscopy at our institution between April 2017 and March 2019. The patients were divided into two groups‚ group A（ureteroscopy after standardization） and group B (ureteroscopy before standardization）. The clinical factors that reduced fluoroscopy time were identified using a multivariate regression model.
　Results: Fluoroscopy time was significantly shorter in group A （0.22 min） than in group B （1.11 min; p = 0.012）; however‚ no significant difference in surgical outcomes including stone free status and postoperative complications was found between the groups. The multivariate regression model identified ureteroscopy with standardizing the fluoroscopic use （odds ratio: 23.90‚ 10.59-50.98; p < 0.001） and ureteroscopy without postoperative ureter stent placement （odds ratio: 4.38‚ 1.98-9.68; p < 0.001） as independent contributors to reduced fluoroscopy time.
　Conclusion: The proposed standardization succeeded to minimized fluoroscopy time without compromising surgical outcomes.},
