title: [Value of the visual stimulation test (VST) as initial paraclinical test in the study of erectile impotence. Classification of psychogenic impotence using computerized rigidimetry. The value of thymoxamine].
abstract: Fifty impotent men between 21 and 65 years old, were all evaluated by nocturnal penile rigidity monitoring (NPRM) with Rigiscan on 2 to 3 successive nights. The results showed 37 normal graphs (74%), and 13 abnormal (26%). As these results confirmed the importance of psychogenic impotence, it was interesting to compare the results of nocturnal erections to those produced by the realtime screening test: the Visual Stimulation Test (VST). This test was done after intracavernous injection of Papaverine and Thymoxamine, alone or combined. The VST seems to be a good screening test. According to the response to VST, psychogenic patients were classified in three groups. This new classification had prognostic and therapeutic implications. The use of Thymoxamine alone at 5 mg or in combination with Papaverine (one mg of each), seems to give better results than Papaverine alone, with minimal pain.
