Introduction A flexible cystoscope is an indispensable tool for urologists, facilitating a variety of procedures in both the operating room and at bedside. Single-use cystoscopes offer benefits including accessibility and decreased burden for reprocessing. The aims of this study were to compare time efficiency and performance of single-use and reusable cystoscopes. Methods Ten new AmbuⓇ aScopeTM 4 Cysto single-use and two Olympus CYF-5 reusable cystoscopes were compared in simulated bedside cystoscopy and benchtop testing. Ten urologists performed simulated cystoscopy using both cystoscopes in a randomized order. Times for supply-gathering, setup, cystoscopy, cleanup, and cumulative time were recorded, followed by a Likert feedback survey. For benchtop assessment, physical, optical, and functional specifications were assessed and compared between cystoscopes. Results The single-use cystoscope demonstrated shorter supply-gathering, setup, cleanup, and cumulative times (824 vs 1231s; p<0.05) but a comparable cystoscopy time to the reusable cystoscope (202 vs 212s; p=0.322). The single-use cystoscope had a higher image resolution but a narrower field of view. Upward deflection was greater for the single-use cystoscope (214.50° vs 199.45°; p<0.001) but required greater force (2.5x). Working channel diameter and irrigation rate were greater in the reusable cystoscope. While the single-use cystoscope lacked tumor enhancing optical features, it had higher Likert scale scores for Time Efficiency and Overall Satisfaction. Conclusion The single-use cystoscope demonstrates comparable benchtop performance and superior time efficiency compared to reusable cystoscopes. However, the reusable cystoscope has superior optical versatility and flow rate. Knowledge of these differences allow for optimal cystoscope selection based on procedure indication.

一次性膀胱镜与可重复使用膀胱镜的时间效率和性能：随机台式和模拟临床评估。

简介 柔性膀胱镜是泌尿科医生不可或缺的工具，有助于在手术室和床边进行各种手术。一次性膀胱镜的优点包括方便使用和减少后处理的负担。本研究的目的是比较一次性和可重复使用膀胱镜的时间效率和性能。方法 在模拟床旁膀胱镜检查和台式测试中对十台新型 AmbuⓇ aScopeTM 4 Cysto 一次性膀胱镜和两台 Olympus CYF-5 可重复使用膀胱镜进行比较。十名泌尿科医生以随机顺序使用两台膀胱镜进行模拟膀胱镜检查。记录用品收集、设置、膀胱镜检查、清理和累积时间的时间，然后进行李克特反馈调查。对于台式评估，对膀胱镜之间的物理、光学和功能规格进行了评估和比较。结果 一次性膀胱镜的耗材收集、安装、清理和累积时间较短（824 秒 vs 1231 秒；p<0.05），但膀胱镜检查时间与可重复使用膀胱镜相当（202 秒 vs 212 秒；p=0.322）。一次性膀胱镜具有较高的图像分辨率，但视野较窄。一次性膀胱镜的向上偏转更大（214.50° vs 199.45°；p<0.001），但需要更大的力（2.5x）。可重复使用膀胱镜的工作通道直径和冲洗速率更大。虽然一次性膀胱镜缺乏肿瘤增强光学功能，但它在时间效率和总体满意度方面具有较高的李克特量表得分。结论 与可重复使用的膀胱镜相比，一次性膀胱镜表现出可比的台式性能和优越的时间效率。然而，可重复使用的膀胱镜具有优越的光学多功能性和流速。了解这些差异可以根据手术适应症选择最佳的膀胱镜。
