The use of an external vacuum device to augment a penile prosthesis

Although penile prostheses are highly effective in the treatment of erectile dysfunction, a small percentage of patients are dissatisfied. Serendipitously, a patient in this group found that using an external vacuum device to augment his prosthetic erection provided a dramatic objective improvement in his erection and increased his overall satisfaction with intercourse. Patients who had tried the combination of external vacuum device and penile prosthesis simultaneously were identified from our penile prosthesis population as well as the Osbon Medical Systems database. Telephone interviews were conducted to determine efficacy, satisfaction, and side effects from the combination. Twelve patients completed the telephone survey. Four patients had semirigid and eight had inflatable penile prostheses. After using the vacuum device to augment the erection, all reported increased rigidity and patient/partner satisfaction, and 11 of 12 described improved length and girth. Minimal complications were noted. Concomitant use of an external vacuum device and penile prosthesis was safe in this select population. The combination may be indicated in patients with penile prostheses who are dissatisfied with size and/or rigidity, and in those who refuse or who are poor candidates for prosthesis revision.
