The Abrams-Griffiths and linear passive urethral relationship (PURR) nomograms are commonly used to diagnose bladder outlet obstruction. To the best of our knowledge there are no clinical studies comparing these 2 evaluations to determine if they similarly predict the findings of bladder outlet obstruction.
From October 1994 through December 1996 multichannel urodynamic studies were performed in 72 men with lower urinary tract symptoms. The data from each urodynamic study were plotted on the Abrams-Griffiths and PURR nomograms.
Using the Abrams-Griffiths nomogram 23 patients (46%) were unobstructed, 15 (21%) were equivocal for obstruction and 24 patients (33%) were obstructed. When the linear PURR nomogram was applied to the pressure-flow data in each group all unobstructed cases were categorized into grade 0 or 1 (no obstruction), equivocal into grade 2 (mild obstruction) and obstructed into grades 3 through 6 (moderate to severe obstruction).
The Abrams-Griffiths and linear PURR nomograms are helpful and comparable clinical tools to assess lower urinary tract symptoms in men. The linear PURR nomogram not only detects the presence of bladder outlet obstruction but grades its severity, which may be helpful to monitor treatment.
艾布拉姆斯 - 格里菲思（Abrams-Griffiths）和线性被动尿道关系（PURR）列线图常用于诊断膀胱出口梗阻。据我们所知，尚无临床研究比较这两种评估方法，以确定它们是否能同样预测膀胱出口梗阻的结果。
1994年10月至1996年12月，对72名有下尿路症状的男性进行了多通道尿动力学研究。将每项尿动力学研究的数据绘制在艾布拉姆斯 - 格里菲思和PURR列线图上。
使用艾布拉姆斯 - 格里菲思列线图，23例患者（46%）无梗阻，15例（21%）梗阻情况不明确，24例患者（33%）有梗阻。当将线性PURR列线图应用于每组的压力 - 流量数据时，所有无梗阻病例被分类为0级或1级（无梗阻），不明确的分类为2级（轻度梗阻），有梗阻的分类为3至6级（中度至重度梗阻）。
艾布拉姆斯 - 格里菲思和线性PURR列线图是评估男性下尿路症状的有用且可比的临床工具。线性PURR列线图不仅能检测膀胱出口梗阻的存在，还能对其严重程度进行分级，这可能有助于监测治疗。
