Detailed Description
An increasing number of men are suffering from the effects of Erectile Dysfunction (ED) each year. The development of oral therapies (phosphodiesterase 5 inhibitors) has been successful for many with the disease. However, these drugs may be contraindicated in patients with cardiovascular risk factors (which are often predecessors to developing ED) and are often ineffective in patients with other comorbid conditions, such as diabetes mellitus. The main objective of this study is to determine the safety and efficacy of low-intensity extracorporeal shock wave therapy using the Dornier Aries in the treatment of erectile dysfunction of vasculogenic origin.
This protocol allows for treatment of 23 men with 21-75 years of age with vasculogenic erectile dysfunction of at least 6 months' duration with low intensity extracorporeal shock wave therapy utilizing the Dornier Aries device.
This protocol includes the application of 5000 shockwaves per session in 5 treatment areas with 1000 SW each at energy level 4-5 (energy flux density (0.051-0.062 mJ/mm²), while moving the applicator along the penile shaft within the treatment areas. The maximum energy applied during this treatment would be 23.35J.
Conversely, the treatment protocol described within is designed to actually restore penile function as a disease-modifying therapy, and is not expected to require a maintenance regimen or continued treatments, as previous studies have demonstrated retained benefits at six months after the end of treatments.
Dornier MedTech hired an independent party to monitor data and perform internal audits to ensure the precision, quality, and integrity of the data collected. The investigator(s) agrees to permit access to study records, source data, and source documents for this purpose.

The treatment protocol includes 1 treatment per week for 6 weeks and an application of 5000 shockwaves per session in 5 treatment areas with 1000 SW each at energy level 4-5 (energy flux density (0.051-0.062 mJ/mm²), while moving the applicator along the penile shaft within the treatment areas. The maximum energy applied during this treatment would be 23.35J.

Outcome Measures
Primary Outcome Measures
- Changes in the mean of the International Index of Erectile Function ED Domain ("IIEF-ED") scores, in the absence of severe adverse events. [1 month and 3 months]
Changes in the mean of the International Index of Erectile Function ED Domain ("IIEF-ED") scores, in the absence of severe adverse events. Higher scores indicate improved functionality according to the minimal clinically important difference (MCID) in erectile function from Rosen et al. 2011.
Secondary Outcome Measures
- Changes in penile base and tip rigidity [3 months]
Changes in penile base and tip rigidity as measured by penile plethysmography (Rigiscan) of the penis will be evaluated and reported.
- Changes in penile cavernosal artery peak systolic velocity (PSV) in [cm/s] by Penile doppler ultrasonography [3 months]
Changes in penile cavernosal artery peak systolic velocity in [cm/s] as determined by color measurement of Penile doppler ultrasonography
- Changes in penile corporal fibrosis [1 month, 3 months]
changes in penile corporal fibrosis as determined by gray scale assessment as measured by duplex ultrasound of the penis during pharmacologic erection will be evaluated and reported
- Changing in Erection Hardness score (EHS) [1 month, 3 months]
EHS increase in patients with EHS < 2.
- Changes in mean scores of the entire IIEF [1 month, 3 months]
Changes in mean scores of the entire IIEF will be evaluated and reported.
- Changes in mean scores of the SEP [1 month, 3 months]
Changes in mean scores of Sexual Encounter Profile (SEP); [Unit on a Scale], will be evaluated and reported.
- Changes in mean scores of the GAQ [1 month, 3 months]
Changes in mean scores of Global Assessment Questionnaire (GAQ); [Unit on a Scale], common, will be evaluated and reported.
