Snap-Gauge band vs multidisciplinary evaluation in impotence assessment

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.
