The Feasibility of Using Dornier Machine in Patients With Erectile Dysfunction, a Pilot Study.
A study testing extracorporeal shock wave therpy in people with Erectile Dysfunction (ED), run by Assiut University.
Trial summary
Extracorporeal Shockwave Therapy (ESWT) is a well-established modality for treating various urological and musculoskeletal conditions. Recently, its application has expanded to include vasculogenic erectile dysfunction (ED), primarily due to its ability to trigger neo-angiogenesis and significantly improve penile… Read more about this study

About this study
Official title: Assessment of the Feasibility and Clinical Efficacy of Low-Intensity Extracorporeal Shockwave Therapy (Li-ESWT) Using the Dornier System in Patients With Vasculogenic Erectile Dysfunction: A Pilot Study
Extracorporeal Shockwave Therapy (ESWT) is a well-established modality for treating various urological and musculoskeletal conditions. Recently, its application has expanded to include vasculogenic erectile dysfunction (ED), primarily due to its ability to trigger neo-angiogenesis and significantly improve penile blood flow.
Read the detailed description
Extracorporeal Shockwave Therapy (ESWT) is a well-established modality for treating various urological and musculoskeletal conditions. Recently, its application has expanded to include vasculogenic erectile dysfunction (ED), primarily due to its ability to trigger neo-angiogenesis and significantly improve penile blood flow. While the clinical efficacy of Low-Intensity Extracorporeal Shockwave Therapy (Li-ESWT) is increasingly recognized globally, it currently remains non-FDA approved for this specific indication. Furthermore, the accessibility of this treatment is often limited, as dedicated Li-ESWT machines are expensive and frequently unavailable in public healthcare settings.
This pilot study investigates the feasibility of adapting the Dornier Delta Lithotripter utilized for high-energy renal stone fragmentation for penile therapy. The central research question focuses on whether this high-energy platform can be safely and precisely calibrated to low-intensity levels to provide therapeutic benefits without inducing tissue damage and complications.
Our clinical rationale is inspired by shifting paradigms in other medical fields, such as prostate cancer radiotherapy, which emphasize delivering a concentrated therapeutic dose in fewer sessions. Since early pilot studies most notably by Vardi et al experimented with standardized five-point techniques over multiple weeks, we seek to optimize this by evaluating the impact of focused energy delivery and modified patient positioning.This research aims to provide a cost-effective, accessible alternative for ED treatment using existing hospital infrastructure.

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Abdelrahman M Abdelkader, Master of Urology & Andrology (+201068336396, abdelrahmanmohamed.aa@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
detection of complications from the use of ESWL machine (time frame: follow up will begin after the first session and then repeated weekly for 1 month). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07331961, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jan 2026.
