Definition Erectile dysfunction (ED) is the inability of a man to maintain a firm erection long enough to have sex. Although erectile dysfunction is more common in older men, this common problem can occur at any age. Having trouble maintaining an erection from time to time isn't necessarily a cause for concern. But if the problem is ongoing, it can cause stress and relationship problems and affect self-esteem. Formerly called impotence, erectile dysfunction was once a taboo subject. It was considered a psychological issue or a natural consequence of growing older. These attitudes have changed in recent years. It's now known that erectile dysfunction is more often caused by physical problems than by psychological ones, and that many men have normal erections into their 80s. Although it can be embarrassing to talk with your doctor about sexual issues, seeking help for erectile dysfunction can be worth the effort. Erectile dysfunction treatments ranging from medications to surgery can help restore sexual function for most men. Sometimes erectile dysfunction is caused by an underlying condition such as heart disease. It's important to take erectile trouble seriously because it can be a sign of a more serious health problem.
Penile erection is a complex phenomenon, which includes coordinated interaction of the nervous, arterial, venous and sinusoidal systems. A defect in any of these systems
may result in erectile dysfunction. Erectile Dysfunction is defined as the consistent inability to generate or maintain an erection of sufficient rigidity for sexual intercourse. Around 10% of men aged 40-70 years have complete, 17.1% have mild and 25.2% have moderate
amount of erectile dysfunction.
50-70% of all Erectile Dysfunction cases are vascular in origin, either arterial insufficiency or venous incompetence.
SonoSource has perfected the ultrasound testing procedures and protocols necessary for thorough evaluation of arterial and venous blood supply to the areas most commonly associated with erectile dysfunction. This specialized exam is highly accurate and is performed in the utmost professional manner in a comfortable, private setting that is well tolerated by the patient. SonoSource has collaborated with Cardiologist and Urologist who are available for consultation and referral for those patients who require additional follow up or intervention.
Ultrasound/ Doppler evaluation in erectile dysfunction (ED) has a significant role in determining the cause of ED. The advantages of penile Doppler and pharmacologic duplex ultrasonography include objective, minimally invasive evaluation of penile hemodynamics at a relatively low cost. Arteriogenic ED may be secondary to peripheral vascular disease and diabetes, or may be seen in association with coronary artery disease. Various parameters, such as diameter of the cavernosal artery, peak systolic flow velocity, degree of arterial dilatation and acceleration time, have been suggested for the diagnosis of arteriogenic ED, but peak systolic flow velocity is the most accurate indicator of arterial disease.
