title: [Diagnosis of erectile dysfunction].
abstract: Erectile dysfunction is a disorder with multifactorial causes. The pathophysiological origin can be severe general disease. Consequently each patient has to undergo a general diagnostic procedure so that severe disease is not missed. The diagnostic work-up of erectile dysfunction follows a three-step scheme of increasing invasiveness. The non-invasive step is the most important. These investigations comprise taking an extensive general history including a detailed sexual history, psychological diagnosis, physical examination, and laboratory tests. The semi-invasive procedures include the intracavernous injection test, colour-coded duplex sonography and optional neurophysiological examinations. The invasive investigations include dynamic infusion pharmacological cavernosography and cavernosometry, and penile angiography. The extensiveness of the diagnostic procedures should be adapted to the complexity of the history and the therapeutic expectations. However, if there is any suspicion of a severe disease remaining undiagnosed, the diagnostic procedures should be adequately comprehensive.
