研究目的:

本研究旨在通过前瞻性、多中心随机对照试验的设计,客观评估超脉冲铥光纤激光器(sTFL)和钬:YAG激光器(Ho:YAG)在输尿管软镜(FURS)碎石术中的临床疗效和安全性差异。通过比较两组患者术后3个月的结石清除率(SFR)、手术时间、并发症发生率以及术者视觉体验等指标,我们将全面分析TFL和Ho:YAG在碎石效率、安全性和操作便利性方面的优劣势,为泌尿外科医生在临床实践中选择最佳激光设备提供循证依据,优化FURS手术方案,最终提升患者预后和满意度。  

Objectives of Study:

This study aims to objectively evaluate the clinical efficacy and safety differences between the super pulse thulium fiber laser (sTFL) and holmium:YAG laser (Ho:YAG) in flexible ureteroscopy (FURS) lithotripsy through a prospective, multicenter, randomized controlled trial design. By comparing the stone-free rate (SFR) at 3 months postoperatively, operation time, complication rate, and surgeon's visual experience between the two groups, we will comprehensively analyze the advantages and disadvantages of TFL and Ho:YAG in terms of lithotripsy efficiency, safety, and operational convenience. This study will provide evidence-based guidance for urologists in selecting the optimal laser equipment in clinical practice, optimizing FURS surgical protocols, and ultimately improving patient outcomes and satisfaction.

盲法:

本次研究采用第三方独立评估的方法,即每一病例都由固定两位对检查结果评价的分析者处于盲态,受试者及治疗者处于非盲态。 具体来说,即是在术后3个月时,由两名独立的放射科医师分别对患者进行非对比增强CT扫描,并对扫描结果进行盲法评估。这两名医师将被严格隔离,不了解患者的分组信息和临床资料,以确保评估过程的盲态。 每位医师将独立判读CT图像,根据残留结石的位置、大小和数量,评定患者的SFR状态。SFR的定义为:残留结石最大直径<2mm或无残留结石。 两名医师的评估结果将进行比对:如果两名医师的SFR判定一致,则以该结果作为最终评估结果;如果两名医师的SFR判定不一致,则由第三名独立的放射科医师对CT图像进行盲法判读,其评估结果将作为最终裁决。

Blinding:

The method of independent third-party evaluation was adopted in this study, that is, each case was blind by two fixed analysts who evaluated the examination results, and the subjects and the treaters were not blind. Specifically, at 3 months after surgery, two independent radiologists performed an uncontrasted enhanced CT scan on the patient, and the scan results were evaluated blind. The two physicians will be strictly isolated from patients' group information and clinical data to ensure a blind evaluation process. Each physician will interpret the CT images independently to assess the patient's SFR status based on the location, size, and number of residual stones. SFR is defined as the maximum diameter of residual stones <2mm or no residual stones. The evaluation results of the two physicians will be compared: if the SFR determination of the two physicians is consistent, the result will be used as the final evaluation result; If the SFR determinations of the two physicians do not agree, the CT images will be blind interpreted by a third independent radiologist whose evaluation will be final.
