[Type V phosphodiesterase inhibitor erection-provoking test with audio-visual sexual stimulation for the diagnosis of erectile dysfunction].
OBJECTIVE
To evaluate the type V phosphodiesterase (PDE-5) inhibitor erection-provoking test with audio-visual sexual stimulation in the diagnosis of erectile dysfunction.


METHODS
A total of 853 out-patients diagnosed with erectile dysfunction were divided into an injury and a non-injury group. After scored on IIEF-5 questionnaires, all the patients received oral administration of PDE-5 inhibitors and, 30 minutes later, audio-visual sexual stimulation. The data on penile erection were recorded with Rigiscan Plus.


RESULTS
The patients with mild, moderate and severe ED accounted for 18.8, 31.9 and 49.3% in the injury group, and 50.6, 39.8 and 9.6% in the non-injury group, with statistic differences between the two groups in the mild and severe parts (P < 0.05). The rates of conspicuous effectiveness, effectiveness, ineffectiveness and total effectiveness of the combined method were 13.0, 14.5, 72.5 and 27.5% in the injury group, but 55.7, 20.7, 23.6 and 76.4% in the non-injury group, with significant differences (P < 0.05).


CONCLUSIONS
The PDE-5 inhibitor erection-provoking test with audio-visual sexual stimulation is a simple, practical, safe and effective method for the differentiation of organic from psychological erectile dysfunction.
