Single use and reusable variants of holmium:YAG laser fibers are available to treat calculi during ureteroscopic procedures. In this prospective, multicenter study we evaluated a series of reusable holmium:YAG laser optical fibers. We hypothesized that reusable fibers provide a cost advantage over single use variants.
We prospectively recorded fiber data, including type, size, number of uses, laser pulse energy and frequency, and total energy delivered. All fibers were new and purchased off the shelf by staff at each institution. We performed a cost analysis comparing reusable fibers to single use variants.
During 541 procedures a total of 37 holmium:YAG optical laser fibers were used, including 21 Laser Peripherals 270 (Laser Peripherals, Golden Valley, Minnesota), 7 Laser Peripherals 365, 4 Lumenis SlimLine™ 200 and 3 Lumenis SlimLine 365 fibers. After stratifying by core size 365 μm core fibers had significantly more uses than 270 μm core fibers (average 23.5 vs 11.3, p < 0.02). By fiber type the mean ± SE number of uses was 12.8 ± 2.44, 3 ± 0.4, 21.3 ± 7.12 and 28.7 ± 6.69 for the Laser Peripheral 270, Lumenis SlimLine 200, Laser Peripherals 365 and Lumenis SlimLine 365, respectively. The total cost savings for reusable fibers vs single use variants was $64,125.
Reusable holmium:YAG optical laser fibers are a more cost-effective option than single use variants. Fibers with a 365 μm core provide more uses than smaller 270 μm variants.
钬:YAG 激光光纤有一次性使用和可重复使用两种变体,可用于输尿管镜手术中治疗结石。在这项前瞻性、多中心研究中,我们评估了一系列可重复使用的钬:YAG 激光光纤。我们假设可重复使用的光纤比一次性使用的变体具有成本优势。
我们前瞻性地记录了光纤数据,包括类型、尺寸、使用次数、激光脉冲能量和频率以及输送的总能量。所有光纤都是全新的,由每个机构的工作人员从货架上购买。我们进行了成本分析,比较了可重复使用的光纤和一次性使用的变体。
在 541 例手术中,共使用了 37 根钬:YAG 光学激光光纤,包括 21 根 Laser Peripherals 270(Laser Peripherals,Golden Valley,Minnesota)、7 根 Laser Peripherals 365、4 根 Lumenis SlimLine™ 200 和 3 根 Lumenis SlimLine 365 光纤。按芯径分层后,365μm 芯光纤的使用次数明显多于 270μm 芯光纤(平均 23.5 比 11.3,p < 0.02)。按光纤类型,Laser Peripheral 270、Lumenis SlimLine 200、Laser Peripherals 365 和 Lumenis SlimLine 365 的平均使用次数分别为 12.8 ± 2.44、3 ± 0.4、21.3 ± 7.12 和 28.7 ± 6.69。与一次性使用的变体相比,可重复使用的光纤可节省 64,125 美元的总成本。
可重复使用的钬:YAG 光学激光光纤比一次性使用的变体更具成本效益。365μm 芯光纤比较小的 270μm 变体提供更多的使用次数。
