title: Can NPTR data predict the cause of organic impotence?
abstract: Conventional diagnostic evaluation, including color duplex doppler ultrasound of the penile vessels, pharmaco-cavernosometry, intracavernosal drug testing and neurologic tests, were used to classify 78 patients with complaints of erectile impotence into one of the following three groups: non-organogenic, arteriogenic, vascular and neurogenic impotence. Nocturnal penile tumescence and rigidity (NPTR) measurements were also performed. Differentiation between patients with organic and non-organic impotence proved possible. The "best night" and "best erection" alone could not outline a pathognomonic pattern for the different causes of organic impotence.
