Shear Wave Elastography New Ultrasound Approach for the Erectile Dysfunction

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.

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.
