Objective:
The aim of this prospective study was to examine the ability of the Snap-Gauge band to differentiate organic from psychogenic erectile dysfunction (ED).
Patients And Methods:
Nocturnal penile tumescence testing was performed on 12 patients using a Snap-Gauge band and RigiScan Plus. A total of 29 nightly examinations were evaluated. The results obtained with the two methods were compared.
Results:
The average tumescence, average rigidity, tumescence activity units and rigidity activity units in the positive group (the group of cases in which one, two or three films of the Snap-Gauge band were broken) were each significantly greater than that in the negative group (the group of cases in which no film was broken). The Snap-Gauge band correctly diagnosed 90% of the patients with a sensitivity of 100% and specificity of 75% with respect to results obtained using the RigiScan Plus.
Conclusions:
The Snap-Gauge band is inexpensive compared to the RigiScan Plus and is relatively reliable. We conclude that the Snap-Gauge band can play a role in ED assessment and can function as a screening device in evaluation of ED.
