Treatment of erectile dysfunction with external vacuum devices

In a retrospective study, the medical and psychological outcome of the use of external vacuum devices in the treatment of erectile dysfunction in 190 patients was evaluated, using a questionnaire and a clinical examination. 110/190 patients (57.8%) answered the questionnaire. 22/110 patients (20%) rejected the device primarily and 34/110 (30.9%) after a period of up to 16 weeks (primary rejection rate 50.9%). A secondary drop-out rate of 8/110 (7.3%) was observed after an intermediate time of 10.5 months. 46/110 (41.8%) patients were long-term users (median 27.6 months, range 7-70 months). Long-term users were mainly patients who did not respond to intracavernosal pharmacotherapy. In the group of long-term users, 98% of patients and 85% of their partners were satisfied with the vacuum therapy. Complications were minor (hematoma 9.8%; skin injury 2.2%), 69.8% of long-term users never had problems with the device. 74% of users reported regular orgasm. Vacuum therapy is a safe and effective non-invasive treatment of erectile dysfunction with a limited primary acceptance and low drop-out rates in long-term follow-ups.
