干预措施:

采用智能可控温控压输尿管软镜,连接医用灌注吸引平台,实时监测并自动调节肾盂内压力(目标0~9 mmHg)和灌流温度(36~43℃),联合铥光纤激光碎石,术中持续负压吸引。

干预措施代码:

Intervention:

Using an intelligent temperature- and pressure-controlled flexible ureteroscope connected to a medical irrigation and suction platform, which monitors in real time and automatically regulates intrarenal pelvic pressure (target 0–9 mmHg) and irrigation temperature (36–43°C), combined with thulium fiber laser lithotripsy, with continuous negative-pressure suction during the procedure.

干预措施:

采用普通输尿管软镜,由助手人工注水维持术野,无智能控压控温功能,同样使用铥光纤激光碎石,必要时间断注水并间歇撤镜协助排石。

干预措施代码:

Intervention:

Using a conventional flexible ureteroscope, with the assistant manually injecting water to maintain the surgical field, without intelligent pressure- and temperature-control functions. Thulium fiber laser lithotripsy is also used, with intermittent water injection and intermittent scope withdrawal to assist stone evacuation when necessary.

随机方法(请说明由何人用什么方法产生随机序列):

采用区组随机化,使用 SAS 9.4 软件生成随机数字序列,通过手机应用程序(APP)完成随机分组。实验组与对照组按 1:1 比例分配。本研究为开放标签(open-label)设计,研究者与受试者均知晓分组情况,但采用随机分配隐藏:当研究人员确认受试者符合入组条件后,将基本信息输入随机系统,系统记录后即通知研究人员该受试者的组别分配。

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

Using block randomization, a random number sequence was generated using SAS 9.4 software, and randomization was completed through a mobile application (APP). The experimental group and the control group were allocated in a 1:1 ratio. This study is an open-label design, in which both investigators and participants are aware of the group assignments. However, allocation concealment was implemented: after the investigator confirms that the subject meets the inclusion criteria, the basic information is entered into the randomization system. Once the system records the information, it notifies the investigator of the subject's group assignment.
