Shear Wave Elastography New Ultrasound Approach for the Erectile Dysfunction

May 18, 2020 updated by: Elisabetta Costantini, University Of Perugia

a New Approach: the Use of Shear Wave Elastosonography of the Corpora Cavernosa for the Diagnosis of Erectile Dysfunction.

the study proposes the use of a new non-invasive ultrasound method for the diagnosis of erectile dysfunction. in particular, the shear Wave elastosonosgraphy of the corpora cavernosa will be used. this last method quantitatively measures the rigidity of the analyzed tissues.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

erectile function is a complex mechanism in which the elasticity of the tissues that make up the corpora cavernosa is fundamental. indeed, anatomopathological studies have shown that in patients with erectile dysfunction the elastic fibers are replaced by inextensible collagen. the aim of the study is the correlation between penile stiffness measured with this new non-invasive diagnostic method - elastosonography of the corpora cavernosa - and the correlation with validated questionnaires. the international Index of Erectile Function (IIEF5) short form and the erectile Hardness Score (EHS) will be used.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

andrological patients
shear wave elastosonography of the corpora cavernosa was performed to all patients who went to our clinic for andrological problems. in addition, the International Index of Erectile Function short form (IIEF5) questionnaire and the Erectile Hardness Score (EHS) questionnaire were administered.
Diagnostic test: shear Wave Elastosonography
both the left cavernous body and the right cavernous body are ideally divided longitudinally into three sections: proximal, middle and distal. subsequently for each section of the corpora cavernosa the stiffness of the tissue is calculated by means of a specific Region Of Interest (ROI). the result is expressed in Kilopascals and in a color scale. when registering the stiffness the patient is asked to hold their breath.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Shear Wave elastosonografy and Erectile tissues Stiffness.
Time Frame: 15 days
use of shear wave elastosonography for the diagnosis of erectile dysfunction by measuring the stiffness of the erectile tissue. the rigidity of the cavernous bodies is expressed in numerical values obtained in Kilopascals.
15 days
Shear Wave Elastosonography and IIEF5 questionnaire
Time Frame: 15 days
comparison between the score in the International index of Erectile Function short form questionnaire (minimum value is 5 and maximum value is 25) and the stiffness values obtained by elastosonography with numerical absolute values obtained in kilopascals
15 days
Shear Wave elastosonography and EHS questionnaire
Time Frame: 15 days
comparison between the score in the Erectile hardness Score questionnaire (minimum value is 0 an maximum value is 4) and the stiffness absolute values obtained by elastosonography with the numerical values obtained in kilopascals
15 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
cut-off value at elastosonography and erectile dysfunction
Time Frame: 15 days
The secondary objective aim of the our study is was to establish a cut-off value expressed in kilopascal to the elastosonographic Shear Wave Eelastosonography examination identifies the patient may develop erectile dysfunction due to cavernous tissue rigidity.

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
