ABSTRACT
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 21ï¼63 (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.Palabras clave
