The objective of the study is to evaluate the reduction in flow and scope deflection of four leading 200-μm marketed laser fibres (Boston Scientific Flexiva™ 200, Boston Scientific Flexiva™ Trac Tip 200, Lumenis SlimLine™ EZ200 and Optical Integrity ScopeSafe™) via a flexible ureterorenoscope. A laboratory-based bench test was performed using a Flex X2™ flexible ureterorenoscope. Mean upward/downward deflection angles and flow rates (ml/min) for each fibre were calculated and compared to a control. The Optical Integrity ScopeSafe™ fibre has the least loss of deflection, losing only 8 % upward and 6 % downward deflection. Deflection loss was significantly less with this fibre compared to all other fibres (p < 0.0001). Mean flow rates were significantly greater with the Optical Integrity ScopeSafe™ laser fibre at 23 ml/min (p < 0.0001). Despite all fibres marketed as 200 μm, the deflection and flow properties show marked variations. The Optical Integrity ScopeSafe™ 200-μm laser fibre offers the best overall performance with significantly improved flow rates and the least loss of scope deflection.
本研究的目的是通过柔性输尿管肾镜评估四种市售的200μm领先激光光纤（波士顿科学公司的Flexiva™ 200、波士顿科学公司的Flexiva™ Trac Tip 200、科医人公司的SlimLine™ EZ200和Optical Integrity公司的ScopeSafe™）的流量减少和镜体偏转情况。使用Flex X2™ 柔性输尿管肾镜进行了一项基于实验室的台架试验。计算了每种光纤的平均向上/向下偏转角和流速（毫升/分钟），并与对照进行比较。Optical Integrity公司的ScopeSafe™ 光纤的偏转损失最小，向上偏转仅损失8%，向下偏转损失6%。与所有其他光纤相比，该光纤的偏转损失显著更小（p < 0.0001）。Optical Integrity公司的ScopeSafe™ 激光光纤的平均流速显著更高，为23毫升/分钟（p < 0.0001）。尽管所有光纤均标称200μm，但偏转和流量特性显示出显著差异。Optical Integrity公司的200μm激光光纤具有最佳的整体性能，流速显著提高，镜体偏转损失最小。
