研究目的:

1.主要目的: 验证“基于人工智能的尿流检测系统(AI-UFD)”在自然排尿环境下测得的最大尿流率(Qmax)、平均尿流率(Qavg)、排尿总量(Uvol)及排尿时间(Utime)等关键尿流动力学指标,与医院标准尿流仪(金标准)检测结果的一致性,并计算 ROC 曲线下面积(AUC)、敏感度、特异度等诊断性能指标,为 AI-UFD 的临床推广提供循证依据; 2.次要目的: (1) 探讨 AI-UFD 提取的尿流参数与患者国际前列腺症状评分(IPSS)、前列腺体积及残余尿量等临床指标的相关性; (2)评估 AI-UFD 系统在门诊及家庭场景中连续监测尿流的可行性与患者依从性; (3)基于 AI-UFD 参数构建多变量模型,实现 LUTS/BPH 患者梗阻风险或疗效预后的辅助预测。  

Objectives of Study:

1. Main Objective: To validate the consistency of key urodynamic indicators such as maximum urinary flow rate (Qmax), average urinary flow rate (Qavg), total urinary volume (Uvol), and voiding time (Utime), measured by the AI-based uroflow detection system (AI-UFD) in a natural urination environment, with the results obtained from the hospital's standard uroflowmeter (gold standard), and to calculate diagnostic performance indicators such as the area under the ROC curve (AUC), sensitivity, and specificity, providing an evidence-based basis for the clinical promotion of AI-UFD; 2. Secondary Objectives: (1) To explore the correlation between the urinary flow parameters extracted by AI-UFD and clinical indicators such as the International Prostate Symptom Score (IPSS), prostate volume, and post-void residual urine volume; (2) To evaluate the feasibility and patient compliance of continuous urinary flow monitoring using the AI-UFD system in outpatient and home settings; (3) To construct a multivariable model based on AI-UFD parameters to aid in predicting the obstruction risk or treatment outcome for patients with LUTS/BPH.

例数:

Sample size:

50

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Male patients ≥18 years with lower urinary tract symptoms (e.g. slow stream, hesitancy), suspected benign prostatic hyperplasia or bladder outlet obstruction, able to void spontaneously. Include spectrum from normal to severe flow impairment.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

患者合并轻度神经源性膀胱或轻度膀胱过度活动症(排尿动力学可相似,但与梗阻机制不同)

例数:

Sample size:

0

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

Patients with mild neurogenic bladder or overactive bladder
