Flexible ureterorenoscopes (FURSs) are considered important additions to urology armamentarium. One of the technical drawbacks is the poor optic image provided by fiberoptic endoscope as well as the fragility of this conventional fiberoptic endoscope. This study aim is to evaluate practical performances and functional durability of the new Olympus digital flexible ureteroscope (ODF-URS) (URF-V) in a single center clinical setting.
A number of 60 diagnostic and therapeutic procedures were performed over a period of 6 months in a single center (Tenon University Hospital), using a single ODF-URS (URF-V). This device provided a 275° maximal down-deflection (MDD) and 180° maximal up-deflection (MUD).
ODF-URS (URF-V) was used for a total time of 90 h and 30 min, with average time duration of 90.5 min per procedure. After 60 procedures, MDD decreased from 275° to 217°, while the MUD decreased from 180° to 161°. During six procedures (10%), URF-V failed to access inferior calyx due to a narrow lower calyx infundibulum.
New ODF-URS (URF-V) is a reliable and durable device, with a good success rate and improved functional parameters. It is a superior device compared to predecessor generations of conventional fiberoptic endoscopes for the light source and the image quality; however, randomized comparative studies are necessary to evaluate performances and durability of this device.
可弯曲输尿管肾镜（FURSs）被认为是泌尿外科器械库的重要补充。其技术缺点之一是纤维内镜提供的光学图像质量差，以及这种传统纤维内镜的易碎性。本研究旨在评估新型奥林巴斯数字可弯曲输尿管镜（ODF - URS）（URF - V）在单中心临床环境中的实际性能和功能耐久性。
在单中心（特农大学医院），使用一台ODF - URS（URF - V）在6个月的时间内进行了60例诊断和治疗手术。该设备的最大向下弯曲度（MDD）为275°，最大向上弯曲度（MUD）为180°。
ODF - URS（URF - V）的总使用时间为90小时30分钟，每次手术的平均时长为90.5分钟。60例手术后，MDD从275°降至217°，而MUD从180°降至161°。在6例手术（10%）中，由于下肾盏漏斗部狭窄，URF - V未能进入下肾盏。
新型ODF - URS（URF - V）是一种可靠且耐用的设备，成功率高且功能参数有所改善。与前代传统纤维内镜相比，它在光源和图像质量方面是一种更优越的设备；然而，需要进行随机对照研究来评估该设备的性能和耐久性。
