This study compares the findings of multidisciplinary evaluation to the two-night use of the Snap-Gauge band in 100 impotent men. An organic etiology was diagnosed in 52 percent of those evaluated. The Snap-Gauge band proved accurate as a screening device for organic disease. If no elements were broken over the two-night period, this finding correlated with multisystemic diagnosis of organic etiology in 86 percent of cases. Among the 52 patients in whom an organic etiology was diagnosed, 32 broke no elements for a 62 percent sensitivity. When more than one element was broken, the predictive value as to etiology of the erectile dysfunction diminished.
本研究将多学科评估结果与100名阳痿男性连续两晚使用Snap-Gauge环的结果进行了比较。在接受评估的患者中，52%被诊断为器质性病因。Snap-Gauge环被证明是一种准确的器质性疾病筛查工具。如果在两晚期间没有元件损坏，这一结果与86%的病例中多系统诊断的器质性病因相关。在52名被诊断为器质性病因的患者中，32名没有元件损坏，敏感性为62%。当有一个以上元件损坏时，对勃起功能障碍病因的预测价值就会降低。
