  Purpose

Low intensity shock waves (LISW) have been proven in animal studies to induce local growth of new blood vessels. The investigators hypothesized that LISW therapy could improve the symptoms of patients with erectile dysfunction resulting from a problem of blood supply that do not respond to oral therapy (PDE-5 inhibitors).

Primary Outcome Measures:
  • IIEF-ED Domain [ Time Frame: 17 weeks ] [ Designated as safety issue: No ]
    A change of 5 points or more will indicate success


Secondary Outcome Measures:
  • rigidity score [ Time Frame: 17 weeks ] [ Designated as safety issue: No ]
    a scale of 3 and above indicates success


Estimated Enrollment: 60
Study Start Date: April 2010
Estimated Study Completion Date: January 2012
Estimated Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Sham Comparator: placebo
We use the same probe that induces the same sensation on the penis and the same noise yet no energy
Device: Extracorporeal Shockwave Therapy Generator (Vascuspec)
Gel is spread around the penis and on the Shock Wave applicator and Treatment (12 sessions in total) of 300 shocks per site, on 5 penile anatomical sites.
Other Names:
  • Low intensity shock wave Therapy
  • Extracorporeal Shockwave Therapy
Active Comparator: Shock wave therapy
12 treatment sessions twice a week during 9 weeks with an interim of 3 weeks no treatment
Device: Low intensity shock wave therapy
Gel is spread around the penis and on the Shock Wave applicator and Treatment (12 sessions in total) of 300 shocks per site, on 5 penile anatomical sites.
Other Name: Low Intensity Extra Corporal Shock Wave Therapy

Detailed Description:

In this study Low intensity shockwaves (1/10 the ones used in Lithotripsy) are delivered directly to the penile tissue using a specially designed shockwave device and probe. Shock wave therapy is applied twice a week for three weeks , then a 3- week interval with no therapy followed by another 3 week period of twice a week shock wave therapy. Before and after sexual function questionnaires and objective measures of erectile function will be performed.
