To describe a novel operative technique resulting in extended durability and improved ease of use of current flexible ureteroscopes (FURS). A surgical method employing a modified technique of using an Olympus digital flexible URF-V ureteroscope was developed.
We retrospectively studied 546 patients who underwent retrograde intrarenal surgery (RIRS) using this modified approach performed by a single surgeon at our hospital, and investigated the outcome and durability of the ureteroscope.
Through the study period, the URF-V ureteroscope required repair five times in total. During factory maintenance, distal working channel damage was noted twice, and outer bending rubber damage was noted once. The most recent two repairs were required due to laser penetration. Despite the damage and repairs, the deflection system was almost entirely intact after high-frequency use. The durability of FURS determines the efficacy of RIRS for renal stones.
In this report, we described our modified upside-down technique for manipulation of FURS under unequal dual deflection in order to preserve the deflection apparatus, which yielded a greatly prolonged durability. Additionally, the use of mimic drive turning decreased the time needed to train urologists.
描述一种新的手术技术，可延长现有软性输尿管镜（FURS）的耐用性并提高其易用性。采用改良的奥林巴斯数字式软性 URF-V 输尿管镜使用技术的手术方法得到了发展。
我们回顾性研究了 546 例在我院由同一位外科医生采用这种改良方法进行逆行性肾内手术（RIRS）的患者，研究了输尿管镜的结果和耐用性。
在研究期间，URF-V 输尿管镜总共需要维修 5 次。在工厂维护期间，注意到远端工作通道损坏两次，外弯曲橡胶损坏一次。最近的两次维修是由于激光穿透所致。尽管有损坏和维修，但高频使用后，偏转系统几乎完全完好无损。FURS 的耐用性决定了 RIRS 治疗肾结石的效果。
在本报告中，我们描述了我们改良的颠倒技术，用于在不等双偏转下操纵 FURS，以保护偏转装置，从而大大延长了耐用性。此外，模拟驱动转向的使用减少了泌尿科医生的培训时间。
