One technical drawback of SU scopes is decreased brightness and clarity of the visual field, which may impair case completion. The Karl Storz FLEX-XC1 is a novel single-use flexible ureteroscope that uses the same video graphics platform as its reusable digital counterpart. We aimed to evaluate the technical performance of the XC1 in initial clinical use. METHODS: We reviewed a series of consecutive ureteroscopy procedures performed by 2 endourologists. We used the XC1 for indications in which we typically use a single-use device: stone burden >15 mm overall or >10 mm in the lower pole; expected case duration >60 min; bilateral procedure; distorted anatomy. For each case, we assessed pre-case tip deflection, intraoperative mechanical failure, and clinical outcomes. Surgeons rated visual clarity, image quality, and mechanical handling on a 1 to 5 Likert scale. RESULTS: A total of 21 procedures were attempted using XC1, and 20 (95%) were completed successfully. Pre-case incomplete deflection was noted in 7 (33%) cases: pre-case upward deflection was <270° in 4 (19%) cases (range 200-250°), and downward deflection was <270° in 5 (24%) cases (range 180-250°). Pre-case incomplete deflection did not preclude completion of any case. Three intraoperative malfunctions occurred: rotational twisting of the deflectable distal tip (2 cases, 10%) and inability to pass a 365-micron laser fiber fully through the working channel (1 case, 5%), requiring conversion to another device. Visual clarity, image quality, and mechanical handling were rated as 4 (very good) or 5 (excellent) in 100%, 100%, and 76% of cases. Figure 1 shows representative image quality between the reusable digital Storz FLEX-XC, SU Storz FLEX-XC1, and SU Dornier AXIS. No device-specific or general 30-day complications were observed. CONCLUSIONS: In this pilot trial of the FLEX-XC1, visual clarity and image quality were subjectively similar to reusable digital devices and rated highly by operators. We observed incomplete deflection in 33% of cases and mechanical failure in 1 case. XC1 may be advantageous in prolonged cases where maintaining visual clarity is paramount.
