[Induratio penis plastica].

The symptoms of Peyronie's disease consist of fibrotic plaque formation, penile deviation and painful erection. The etiology is still unknown. During its progress the disease can cause erectile failure. The plaques mainly involve the dorsal tunica of the penis. The diagnosis is made by palpation of the penis. The ultrasound examination evaluates the plaque localization and possible calcifications. Autophotography of penile deviation and duplex sonography of the cavernous arteries used to measure arterial blood flow complete the diagnostic efforts. Spontaneous remissions occur as well as chronic courses. Oral medication is the first step in therapy. In cases with severe penile deviation leading to disability to perform intercourse, persisting pain or erectile failure operative management is indicated. Plaque surgery, modified corporal plication or implantation of a penile prosthesis must be evaluated individually.
