Clinical Studies

The Journal of Urology Vol. 156.2007-2011, Dec. 1996 reports in a Special Communication from the AUA clinical guideline panel. They recommend vacuum therapy as their first choice of treatments for Erectile Dysfunction.
 
The British Journal of Urology (1998), 82, 673-681 states that as many as 32% of the men in one of their studies, eventually achieved normal erections without the use of the pump. They also report that many studies on the general population report the return of spontaneous erections in as many as 25% of the patients. One study in particular, with daily use of the vacuum as a therapy situation, stated that 60% showed improvement in normal erections.
 

The Journal of Urology Vol. 166, 1779-1781 Nov., 2001, reports the adverse side effects of Sildenafil were the main reasons for preferring a vacuum therapy system. The conclusion, that even in an era of effective oral medication. vacuum therapy remains a preferred treatment.

 

The British Journal of Urology (1995), 76, 757-760 reports, several studies have demonstrated that vacuum therapy systems can produce erections in 89-100% of men with erection problems.

 

The Journal of Urology Vol. 144 July, reports in a study that men who regularly use vacuum therapy systems report significant improvements in quality and frequency of intercourse, frequency of orgasm and sexual satisfaction, as well as decreased psychiatric symptoms, increased self-esteem and a trend toward improved martial satisfaction. They also report that studies have demonstrated that vacuum therapy systems have produced erections in as many as 100% of the men with erection problems of various causes.

They also state the quality of system induced erections, was significantly improved. There was significant improvement in the spontaneous capacity for erection after use of a system. A previous study indicated 40% of the men reported they had begun to achieve better erections with frequent use of a system. Partners reported greater satisfaction.

 

The Journal of Urology Vol.141, Feb., reports no serious ill effect from use of the system, and has reported that it is particularly effective in the management of partial Impotence. They go on to state a reversible noninvasive form of treatment appears to be ideal. They further state that after 8.6 months 25% of the subjects in their study were able to occasionally have intercourse without using the system.

 

Urology, Oct. 1991 Vol. XXXVIII, Number 4, reports that The Department of Urology Tulane University and Veterans Affairs Center States the U.S. Food And Drug Administration lists the vacuum therapy system as safe, non-surgical therapy for erectile dysfunction. They go on to say that vacuum therapy systems are the least invasive and most successful method available. They also state the use of a vacuum therapy system is safe and effective, with no reports of complications.

The Journal of Urology Vol. 144, Nov., reports a recent study performed on 127 patients, a high rate of satisfaction with vacuum therapy systems. They further report after various treatment options for impotence were discussed their patients elected to use vacuum therapy systems.

 

Urology Mar. 1993, Vol. 41, #3, reports that the erectile dysfunction Clinic study wrote that vacuum therapy systems will help regardless of the cause. They also state they recommend vacuum therapy for all patients with documented venous leakage.

 

The British Journal of Urology (1995) 76.757-760. Reports in a study performed at the Ankara School of Medicine, that 88% had satisfactory results and had an improvement in the capability for normal erections with the vacuum therapy system.

 

Journal of Urology Vol. 155, 534-535 Feb. 1996,. Reports use of a non-medical type of vacuum therapy system resulted in a case of vacuum induced vasculogenic impotence and Peyronie’s disease.

They further report that medical grade vacuum therapy systems provide a safe, effective inexpensive and noninvasive therapeutic option for impotent men. Medical systems differ from the nonmedical devices in that the medical systems use pressure release valves.

 

The Journal of Urology Vol. 140, Nov. Reports 30-35 per cent of the patients may have only partial response to injection therapy. in a study of 22 men after injection, only partial tumescence was attained vacuum therapy was applied to all 22 men and 21 responded in seconds with rigid erections. In summary they demonstrated that vacuum therapy systems may augment a partial response to injection therapy.

 

“Treating Impotence” by Perry W. Nadig, M.D., states that many reports have been published about vacuum therapy systems effectiveness and safety, he also states that no serious injury due to the use of vacuum therapy has ever been reported. He states best of all, the vacuum therapy system is the safest and least expensive method of treatment available.

“Vacuum Erection Devices” by Perry W. Nadig, M.D. Jan. 1990 states that vacuum therapy systems create penile rigidity sufficient for vaginal penetration in over 98% of the men who try it, and that few men fail without apparent cause.

Dr. Nadig further states even men who have had a penile implant removed can use the vacuum therapy system successfully. If a malfunctioning penile implant is still in place the vacuum therapy system can be used to obtain rigidity or increase the girth of the penis.

He goes on to state the it has been suggested the the VTS can augment the effect of of injection therapy for men in whom these injections alone failed. He reports that no serious complications reported due to the use of VTS have appeared.

In a study by Kursh and his associates, Dr. Nadig reports that a prospective evaluation of the the use of Vacuum therapy by 40 impotent men the Vacuum therapy produced a “satisfactory erection” in all but one. With no serious complications observed.

Dr. Nadig concluded, to date vacuum therapy systems appear safe and generally effective, enabling a large percentage of impotent men to enjoy sexual intercourse. The vacuum therapy system fulfills the need of these men and should be offered, along with other appropriate treatments to every impotent man.

 

Contemporary Urology Dec. 1994 Vol. 6 No.12, Dr. Irwin Goldstein, M.D., states medical grade vacuum therapy systems are reliable, safe, and predictable therapy, and that safety is important to communicate to patients.

 

International Journal of Impotence Research, Vol. 4, Supp. 2, Sept. 1992. Reports that In a study performed by the Institute of Urology, Milano, Italy.

The Pos-T-Vac vacuum therapy system was used once a day without a constrictive band applied to the penis root, in order to generate a passive action on the erectile tissue, thus”stretching” the smooth muscle fibers. Patients who underwent vacuum therapy daily showed, at the end of the treatment (6 months), a significant improvement in spontaneous erectile ability.

 

The Journal of Urology Vol. 149, 290-294, Feb. 1993 Long Term Results, presented by Michael S. Cookson and Dr. Perry W. Nadig.

Quality of erection was evaluated for hardness, length and circumference, and with satisfaction greater that 90% in both groups treated.

They report the impact of impotence on health care dollars can be expected to grow as the number of elderly patients at higher risk for erectile dysfunction continues to increase. They further state vacuum therapy systems have gained widespread acceptance in the management of impotence. High rates of success and patients satisfaction with the vacuum therapy system combined with its relatively low cost and safety have helped to establish its clinical efficacy. Of the tests results listed most patients either reported no change or an increased ability to achieve climax or orgasm. They go on to say it appears that satisfaction and successful use of the vacuum therapy system can be expected from patients with a history of pharmacological injection therapy, including those who failed this form of treatment. Vacuum therapy systems have proved successful in patients who failed prior penile prostheses. The report states that Turner et al reported with vacuum therapy use comes an increase in partner arousal, ability to achieve orgasm during intercourse and overall greater partner satisfaction.

The study continues to say that Vacuum therapy systems appear to be a viable option in the treatment of impotence regardless of risk factors. Vacuum therapy systems appear to be an effective and durable nonoperative treatment for erectile dysfunction, and its use should be continue to increase along with its growing population.

The editorial states this study confirms the long-term efficacy of this therapy suggests that the vacuum therapy system should be offered as a treatment alternative in most men with erectile dysfunction. It became evident that many patients offered the vacuum therapy system were satisfied. From meager beginnings, the vacuum therapy system has emerged as respected and useful component of impotence therapy.
