随机方法(请说明由何人用什么方法产生随机序列):

由独立生物统计师使用pyhon生成随机分配序列,采用中心分层、可变区组长度的区组随机化,通过交互式网络应答系统(IWRS)实施分配隐藏。

Randomization Procedure (please state who generates the random number sequence and by what method):

The random allocation sequence will be generated by an independent biostatistician using python. Center-stratified block randomization with variable block lengths will be used, and allocation concealment will be implemented through an Interactive Web Response System (IWRS).

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

(1)设盲对象:a.受试者(患者):在整个研究期间,受试者将不知道自己所接受的是球囊冲洗(试验组)还是网篮冲洗(对照组)。在知情同意过程中,将告知其分组由计算机随机决定且对其保密。b.结局评估者与数据分析人员:(评估结石复发)的研究人员,以及在首次分析时的生物统计师,均对分组信息保持盲态。 (2)设盲对象:手术操作者(内镜医师)及手术室团队:由于两种操作技术器械与手法差异显著,无法对术者设盲。但将通过?《标准化操作流程》?规范操作,以最大限度减少由此带来的偏倚。

Blinding:

Subjects of blinding: a. Participants (patients): Throughout the study period, participants will not know whether they are receiving balloon irrigation (experimental group) or basket irrigation (control group). During the informed consent process, they will be informed that group assignment is determined by computer randomization and will be kept confidential from them. b. Outcome assessors and data analysts: Researchers assessing (stone recurrence) and biostatisticians conducting the initial analysis will remain blinded to group allocation. Non-blinded subjects: Operators (endoscopists) and operating room team: Due to significant differences in and techniques between the two procedures, blinding of operators is not feasible. However, operations will be standardized through the Standard Operating Procedure (SOP) to minimize potential bias arising from this limitation.
