Outcome:

Renal function recovery

Type:

Secondary indicator

测量时间点:

测量方法:

术前、术后 1 周及术后 4–6 周检测 Scr、BUN,比较与基线变化

Measure time point of outcome:

Measure method:

Serum creatinine (Scr) and blood urea nitrogen (BUN) will be measured preoperatively, at 1 week postoperatively, and at 4–6 weeks postoperatively, and compared with baseline values.

指标中文名:

支架管留置时间

指标类型:

次要指标

Outcome:

Ureteral stent indwelling time

Type:

Secondary indicator

测量时间点:

测量方法:

由临床医师根据患者术后恢复情况、结石残留情况等综合判断,记录从支架管置入到取出的时间间隔

Measure time point of outcome:

Measure method:

Clinicians comprehensively judge according to the patient's postoperative recovery and stone residue, and record the time interval from stent placement to removal.

指标中文名:

支架管症状评分

指标类型:

主要指标

Outcome:

Ureteral stent symptom score

Type:

Primary indicator

测量时间点:

测量方法:

采用相关量表(如 ureteral stent symptom questionnaire),从尿频、尿急、尿痛、腰痛、血尿等方面对患者进行评分,由患者根据自身症状填写量表

Measure time point of outcome:

Measure method:

A relevant scale (such as ureteral stent symptom questionnaire) is used to score patients in terms of frequent urination, urgent urination, dysuria, low back pain, hematuria, etc., and patients fill in the scale according to their own symptoms.

Measure time point of outcome:

Measure method:

Same as the measurement method of "postoperative stone clearance rate", that is, judge the stone residue by imaging examination and calculate the stone - free rate (stone - free rate = number of patients without stone residue / total number of patients × 100%).

随机方法(请说明由何人用什么方法产生随机序列):

由研究团队中的统计专业人员,使用随机数字表法产生随机序列,将符合纳入标准的患者随机分配至治疗组(术后置入三棱形输尿管支架管)和对照组(置入常规输尿管支架管)。

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

Statistical professionals in the research team generate the random sequence using the random number table method, and randomly assign patients who meet the inclusion criteria to the treatment group (triangular prism - shaped ureteral stent placed after surgery) and the control group (conventional ureteral stent placed).

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:

采用单盲法,即患者对所放置的支架管类型(三棱形支架管或普通圆形支架管)不知情,而术者、研究者及随访人员知晓分组情况。

Blinding:

A single - blind method was adopted. That is, patients were unaware of the type of ureteral stent placed (triangular prism - shaped stent or ordinary circular stent), while surgeons, researchers, and follow - up personnel were aware of the grouping.

本研究的数据采集包括纸质版病例报告表(CRF)和电子数据采集与管理系统(EDC)两部分。研究者首先通过纸质CRF记录受试者基线特征、围术期评估及随访信息,随后由双人核对后录入至ResMan数据管理平台进行电子化存储与管理。所有数据均采用唯一编码进行匿名化处理,仅授权研究团队成员可访问。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection in this study includes both a paper-based Case Report Form (CRF) and an electronic data capture and management system (EDC). Participant baseline characteristics, perioperative assessments, and follow-up data are first recorded in the CRF and then double-checked and entered into the ResMan data management platform for secure electronic storage and management. All data are anonymized with unique participant codes, and access is restricted to authorized study personnel only.
