We correlated multichannel pressure-flow urodynamics and the American Urological Association (AUA) symptom index in the evaluation of benign prostatic hyperplasia.
We evaluated 121 consecutive, symptomatic patients older than 55 years with the AUA symptom score and multichannel pressure-flow urodynamic studies. Testing was performed during a single session and the data obtained from 103 patients were plotted on the Schäfer nomogram for assessment of outflow obstruction. Linear regression statistical analysis was used to determine correlations.
There was no significant correlation between uroflowmetry and Schäfer curves (r = 0.173 to 0.326), uroflowmetry and AUA symptom scores (r = 0.134 to 0.153) and, most importantly, AUA symptom scores and Schäfer curves (r = 0.025 to 0.137).
We conclude that these modalities measure independent variables, and should not be linked in the evaluation and treatment decision of the patient with prostatism.
我们在良性前列腺增生的评估中，对多通道压力-流率尿动力学检查结果与美国泌尿外科学会（AUA）症状指数进行了相关性分析。
我们对121例年龄超过55岁、有症状的患者进行了AUA症状评分及多通道压力-流率尿动力学检查。检查在一次就诊期间完成，从103例患者获取的数据被绘制在施费尔列线图上，以评估流出道梗阻情况。采用线性回归统计分析来确定相关性。
尿流率与施费尔曲线之间（r = 0.173至0.326）、尿流率与AUA症状评分之间（r = 0.134至0.153），以及最重要的是，AUA症状评分与施费尔曲线之间（r = 0.025至0.137）均无显著相关性。
我们得出结论，这些方法测量的是独立变量，在前列腺增生患者的评估和治疗决策中不应将它们联系起来。
