Background
Erectile dysfunction (ED) is defined as the inability to attain or maintain a penile erection of sufficient quality to allow satisfactorysexual performance. The prevalence of this condition increases with age with a 39% prevalence at the age of 40 years and a 67% prevalence at the age of 70years.It has been estimated that the worldwide prevalence of erectile dysfunction will be 322 million cases by the year 2025. Sexual function is a complex process involving both biologic and psychological...
Findings and procedure details
Diagnostic Imaging in Erectile Dysfunction: Color Doppler Ultrasound (CDUS). Stimulated Doppler Ultrasound is a reliable,
noninvasive diagnostic method that is used in the evaluation of men presenting with erectile dysfunction (ED).
This imaging and functional test provides objective quantification of erectile hemodynamics and can elucidate conditions such as corporal veno-occlusive dysfunction (venous leak),
arterial insufficiency,
penile arterio-venous shunts,
cavernosal fibrosis,
and...
Conclusion
Erectile dysfunction is defined as the inability to attain or maintain a penile erection of sufficient quality to allow satisfactorysexual performance.The prevalence of this condition increases with age. There are many causes of erectile dysfunctionincluding organic,
psychogenic,
and combined causes.
It is essential to identificate organic causes,
because they are potentially treatables. Erectile dysfunction is now being recognized as one of the earliest manifestations of endothelial...
