AbstractIntroduction: Studies comparing different single-use flexible ureteroscope (su-fURS) models are lacking. The objective was to compare three types of su-fURS: the Uscope 3022 (PUSEN), LithoVue (Boston Scientific), and EU-scope (Innovex). Methods: This was a retrospective study comparing the clinical outcomes from patients undergoing flexible ureteroscopy with one of the three su-fURS for upper urinary tract stone treatment between September 2019 and 2021. Analysis included total surgery and fluoroscopy time, post-procedure ureteral catheter, stone-free rate (SFR), and complications. Results: There were 104 cases with the Uscope 3022, 141 with LithoVue, and 80 with EU-scope. Groups were comparable in terms of stone size, location and density, and prior double-J stent presence. Multivariate analysis showed no difference in terms of SFR: 79% (Uscope 3022), 77.5% (LithoVue), and 81% (EU-scope); p = 0.38. Significant differences were found for total surgery and fluoroscopy time, as well as ureteral access sheath use (p < 0.001), favoring the EU-scope group. Discussion/Conclusion: The three devices evaluated are highly effective in treatment of kidney stones. Reasons for difference in total surgery and fluoroscopy time and access sheath use are not clear. However, this could be explained by technical aspects of these devices, such as external diameter, optical resolution, and field of view.
