研究目的:

本项目旨在探讨输尿管软镜在治疗≤2cm的肾结石术后不留置双J管与常规留置双J管这两种处置措施在结石清除率、并发症等可行性和安全性指标上的差异,以为今后输尿管软镜治疗流程的优化提供更多参考依据,为输尿管软镜术后无管化的应用提供高质量的医学证据。  

Objectives of Study:

This project aims to explore the difference in stone-free rate (SFR) and other feasibility and safety indicators between two treatment measures (tubeless and conventional indwelling D-J tube) after Flexible ureteroscopic lithotripsy for renal stones ≤2 cm. To provide more reference for the optimization of the treatment process of flexible ureteroscopy in the future, and provide high-quality medical evidence for the application of tubeless after flexible ureteroscopy.

随机方法(请说明由何人用什么方法产生随机序列):

采用分层区组随机化,在每家医院进行区组随机化。通过SAS 9.4统计软件采用区组随机化方法生产随机编码,按1:1随机分为试验组(无管化组)和对照组(常规置管组)。各医院按受试者入组顺序,根据计算机产生的随机编号予受试者进行相应处理。

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

Stratified block randomization was performed at each hospital.SAS 9.4 statistical software was used to produce random codes using the block randomization method and randomly divided into experimental group (tubeless group) and control group (conventional tube group) according to 1:1. Each hospital will process the subjects
