[Vacuum therapy for erectile dysfunction that fails to respond to PDE-5i: report of 70 cases].

OBJECTIVE: To assess the efficacy and safety of the Osbon ErecAid Vacuum Therapy System in the treatment of erectile dysfunction (ED) that fails to respond to PDE-5i. METHODS: This study included 70 cases of ED not responding to the medication of PDE-5i. The patients were aged 25 -66 (38.9 +/- 9.1) years. Under our direction, the patients used the Osbon ErecAid Vacuum Therapy System for a month to increase blood oxygenation to the corpora cavernosa, and then employed the vacuum constriction device (VCD) to maintain penile erection for sexual intercourse. We compared their IIEF-5 scores and their and their partners' sexual satisfaction before and 3 months after treatment, and evaluated the safety and effect of the vacuum therapy. RESULTS: The mean IIEF-5 scores of the patients were significantly increased from 10.2 +/- 4.0 before treatment to 13.3 +/- 4.7 at 3 months after the vacuum therapy (P < 0.05). The rate of therapeutic effectiveness was 77.1% (54/70), and the rates of sexual satisfaction of the patients and their partners were 64.3% (45/70) and 65.7% (46/70), CONCLUSION: Vacuum therapy for ED that does not respond to PDE-5i can significantly improve the patients' erectile function as well as their and their partners'sexual satisfaction, and therefore deserves clinical application.
