The Jonas prosthesis--technical considerations and results.

We analyzed 100 patients who underwent implantation of the Jonas penile prosthesis because of impotence, complications, and patient and partner satisfaction. Data were gathered by direct patient contact and mailed questionnaires, and at followup ranging from 4 to 18 months. Complications occurred in 7 patients. Of the 100 patients 90 were satisfied with the results and would choose the same operation again, although 20 claimed to have some difficulty with concealment of the penis. A total of 56 patients underwent implantation of the prosthesis under local anesthesia, which has resulted in diminished patient risk as well as reduced cost and duration of hospitalization.
