药物成份或治疗方案详述:

本研究是一项前瞻性、盲法、随机对照试验。本次审判分为两个阶段。第一阶段是概念验证试验,这是一项单中心、前瞻性、盲法、随机对照临床研究。符合筛选标准的受试者按1:1的比例随机分为干预组和对照组。所有受试者在治疗后第2、4、8、12和4周接受安全性和有效性评估。第20名研究对象完成4周随访后,以干预组在随访点相比对照组动静脉内瘘成熟率较高的预设目标进行分析,结果显示:评估了该研究的安全性。第二阶段为关键试验,是一项多中心、前瞻性、盲法、随机对照临床研究。研究对象的纳入标准、主要和次要终点以及安全终点保持不变,并评估总体人群的安全性和有效性。 

Description for medicine or protocol of treatment in detail:

This study is a prospective, blinded, randomized controlled trial. This trial is divided into two stages. The first stage is a concept validation trial, which is a single center, prospective, blinded, randomized controlled clinical study. Subjects who meet the screening criteria are randomly divided into an intervention group and a control group in a 1:1 ratio. All subjects underwent safety and efficacy evaluations at the 2nd,4th,8th,12th, and 4th week after treatment. After completing a 4-week follow-up of the 20th study subject, an analysis was conducted with the preset goal of achieving a higher maturation rate of arteriovenous fistula in the intervention group compared to the control group at the follow-up point, and the safety of the study was evaluated. The second stage is a key trial, which is a multicenter, prospective, blinded, randomized controlled clinical study. The inclusion criteria, primary and secondary endpoints, and safety endpoints of the study subjects remain unchanged, and the safety and efficacy of the overall population are evaluated.

随机方法(请说明由何人用什么方法产生随机序列):

第一阶段使用计算机生成的随机序列在外部进行,将受试者随机分为LIPUS动静脉内瘘干预组和模拟LIPUS对照组,每组各10例。 第二阶段基于网络的随机化系统。筛选合格的受试者,入选时按顺序编号进行。体外低强度脉冲超声操作者根据受试者编号,按分组情况进行操作。

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

Step1: Using a computer-generated random sequence externally to randomly assign the subjects into the LIPUS intervention group for arteriovenous fistula and the simulated LIPUS control group, with 10 cases in each group. Step2: Basing web randomized system, qualified subjects are selected and assigned sequential numbers upon enrollment. Operators of extracorporeal low-intensity pulsed ultrasound perform procedures based on the subject's assigned number and grouping.
