OBJECTIVE: To explore the clinical value of phosphodiesterase type-5 inhibitors (PDE-5i) combined with RigiScan-based audiovisual sexual stimulation (AVSS) test in comparison with that of nocturnal penile tumescence (NPT) test in evaluation of erectile function.
METHODS: A total of 166 ED patients, aged 21－63 (mean 31) years, with a disease course of 3 months to 10 years (mean 14 months), underwent NPT test or PDE-5i + RigiScan-based AVSS test from 2017 to 2018. We compared the results of the diagnostic strategies. Normal NPT patterns were presumed to indicate psychogenic and abnormal ones to indicate organic ED.
RESULTS: Compared with the results of NPT test, no statistically significant difference was observed in the accuracy rate between Viagra + AVSS test and Cialis + AVSS test (P > 0.05). PDE-5i + RigiScan-based AVSS test achieved a sensitivity of 78.9% and a specificity of 90.7% in the diagnosis of psychogenic ED and an overall accuracy rate of 81.9%. According to the results of PDE-5i + RigiScan-based AVSS test, the patients fell into a normal and an abnormal erection group, with significant differences between the two groups in age, disease course, IIEF-5 score and maintenance time of penile tip rigidity ≥60% (P < 0.05). ROC curve analysis indicated that PDE-5i + RigiScan-based AVSS test accurately manifested the erectile function of the patients.
CONCLUSIONS: Compared with NPT test, PDE -5i combined with RigiScan-based AVSS test is simple, inexpensive, practical and with a high sensitivity and specificity, and therefore can be used as the first-choice strategy for etiological diagnosis of ED.
