We aimed to evaluate the durability and cost effectiveness of the latest digital flexible ureterescope by comparing it with the conventional fiberoptic one.
Data of patients who underwent retrograde intrarenal surgery between January 2013 and December 2014 were collected. Fiberoptic Flex-X2 or digital Cobra vision flexible ureteroscopes were used for the procedures. The comparison of both ureteroscopes was performed in terms of patient and stone characteristics, operative outcomes, durability, and cost effectiveness.
A total of 105 patients were evaluated for the study. The patient and stone characteristics and operative outcomes were similar between the groups. Overall, 54 and 51 procedures were performed using Flex-X2 and Cobra vision, respectively, before they were sent for renovation. The purchase prices were USD 29,500 for Flex-X2 and USD 58,000 for Cobra vision. Costs of per case were determined as USD 549.29 for Flex-X2 and as USD 1,137.25 for Cobra vision. Per minute working time costs were USD 772.04 and 1,471.33 for Flex-X2 and Cobra vision respectively.
The digital Cobra vision has high costs without any difference in durability as compared to Flex-X2. Moreover, it has no benefit over Flex-X2 in terms of surgical outcomes.
我们旨在通过将最新的数字柔性输尿管镜与传统纤维光学输尿管镜进行比较，评估其耐用性和成本效益。
收集2013年1月至2014年12月期间接受逆行肾内手术患者的数据。手术中使用纤维光学Flex-X2或数字Cobra vision柔性输尿管镜。对两种输尿管镜在患者和结石特征、手术结果、耐用性和成本效益方面进行比较。
共有105例患者纳入本研究评估。两组患者和结石特征以及手术结果相似。总体而言，Flex-X2和Cobra vision分别在进行54例和51例手术后送去翻新。Flex-X2的购买价格为29,500美元，Cobra vision为58,000美元。Flex-X2每例成本确定为549.29美元，Cobra vision为1,137.25美元。Flex-X2和Cobra vision每分钟工作时间成本分别为772.04美元和1,471.33美元。
与Flex-X2相比，数字Cobra vision成本高昂且耐用性无差异。此外，在手术结果方面，它相对于Flex-X2并无优势。
