A Single-Center Prospective Comparative Study of Two Single-Use Flexible Ureteroscopes: LithoVue (Boston Scientific, USA) and Uscope PU3022a (Zhuhai Pusen, China).

Abstract：

: Introduction and Objective: Single-use flexible ureteroscopes have the benefit of decreasing infection transmission, avoiding sterilization need, and no maintenance cost. Primary objective was to compare in vivo performance and surgical outcomes with two single-use ureteroscopes: LithoVue (Boston Scientific, USA) and Uscope PU3022a (Zhuhai Pusen, China) with secondary objective being to compare in vivo vision by independent endourologist blinded to ureteroscope manufacturer. Materials and Methods: Fifty patients undergoing retrograde intrarenal surgery with <2 cm renal stones were prospectively allocated: Group 1 (25 patients) for LithoVue and group 2 (25 patients) for Uscope. Pre-, intra-, and postoperative parameters were evaluated. Vision of both ureteroscopes with and without accessory was evaluated by an independent endourologist, blinded to the make of the ureteroscope. Stone clearance was assessed with kidney, ureter, and bladder radiograph (KUB) and ultrasonography KUB at 1 month. Student's t-test for quantitative and chi-square for categorical data was used. Results: Pre- and intraoperative parameters such as need for ureteral dilatation (p > 0.05), ureteral access-sheath size (p = 0.78), accessibility to pelvicaliceal system (p > 0.05), and maneuverability (p > 0.05) were comparable in both groups. Lower-pole access was possible in all cases of LithoVue and slightly difficult in three cases of Uscope (p > 0.5). Intraoperative vision was hazy in four cases of LithoVue and eight cases of Uscope (p = 0.32) during lasing along with three cases of Uscope with accessory (p = 0.24). Blinded endourologist reported more cases of hazy vision with or without accessory or lasing in Uscope arm (p > 0.05). One device had malfunction in LithoVue arm. Complete stone clearance was achieved in all cases at 1 month. Conclusions: We conclude that performance of these two single-use ureteroscopes, LithoVue and Uscope, is comparable in clinical settings with similar clinical outcomes and complications.
