Experience with the Jonas penile prosthesis in the treatment of impotence.

The penile prosthesis has become established as a mode of therapy for organic and chronic psychogenic impotence. The Jonas type of penile prosthesis has been implanted into 10 patients and has achieved both functional success and excellent acceptance by the partner. Mechanical and pathological complications have a very low incidence. This penile prosthesis should be made available to carefully selected impotent patients who are deemed psychologically suitable candidates and in whom medical treatment has failed or is not indicated. It represents an important advance in the treatment of the male with erectile impotence.
