Male Genitalia Surgery
Failing to achieve and/or sustain an erection is the primary sign of ED. But diagnosing the specific cause and prescribing appropriate treatment usually require a variety of tests, beginning with a complete history and physical examination.
Your doctor may order additional laboratory tests to assess any conditions that may be interfering with normal erectile function, particularly arterial flow to the penis. A blood test, for instance, is normally used to reveal blood lipids and triglycerides, both of which indicate atherosclerosis if elevated. A urinalysis identifies protein and glucose levels that can suggest diabetes.
While these analyses focus on your chemical status, erectile function tests are the principal tools your doctor will use to tell how the blood vessels, nerves, muscles and other tissues of your penis and pelvic region are working. Normal Nocturnal Penile Tumescence ( NPT ), or healthy involuntary erections during sleep, suggests that nerve function and blood supply are intact.
An imaging technique called duplex ultrasound may also be used. It monitors blood flow, vein leaks, scarring of erectile tissue and some signs of atherosclerosis. During the test, an erection may be produced by injecting the stimulator prostaglandin into the penis and then measuring vessel expansion and penile blood pressures and flow, both of which are compared to the limp penis. In either case, duplex ultrasound can illustrate a specific blood vessel disease that may rule out a need for vascular surgery.
How erectile dysfunction (ED) is surgically treated?
The past several decades have ushered in a new treatment era for ED. Because of the advent of many advances, today urologists are helping millions of impotent men perform better and longer.
Penile prostheses : Surgically implanted devices to ensure rigid erection have become highly reliable therapeutic solutions. See ED: Penile Prostheses
Vacuum erection devices : Vacuum erection devices have proven to be safe alternatives in producing rigidity of the penis by drawing blood into the organ with a pump and holding it with an “occluding band”.
Penile injection therapy : Penile injection therapy is a relatively quick and effective way to send vasoactive drugs directly into the corpora cavernosa where they expand the vessels, relax the tissue and increase blood flow for an erection.
Oral Therapy : Furthermore, the pills: sildenafil, tadalafil and vardenafil have become the treatments of choice for millions of men who have experienced the drugs’ ability to boost levels of Cyclic Guanosine Monophosphate ( cGMP ), a chemical factor in metabolism responsible for relaxing blood vessels.
Penile arterial revascularization : This procedure is designed to keep blood flowing by rerouting it around a blocked or injured vessel. Indicated only for young men ( under 45 ) with no known risk factors for atherosclerosis, this procedure is aimed at correcting any vessel injury at the base of the penis caused by adverse events such as blunt trauma or pelvic fracture. When such an event leaves a penile vessel too injured or blocked to transfer blood, the surgeon may microscopically connect a nearby artery to get around the site, clearing the pathway so enough blood can be supplied to the penis to enable an erection.
Venous ligation surgery : This procedure focuses on binding leaky penile vessels that are causing penile rigidity to diminish during erection. Because venous occlusion, necessary for sufficient firmness, depends on arterial blood flow and relaxation of the spongy tissue in the penis, this approach is designed to intentionally block off problematic veins so that there is enough blood trapped in the penis to create an appropriate erection. Since long-term success rates are less than 50 percent, this technique is rarely a choice for correcting ED.
In fact, you are not a candidate for either penile vascular surgery if you have insulin-dependent diabetes or widespread atherosclerosis. You are also not suited if you still use tobacco or experience consistently high blood serum cholesterol levels. Neither of these surgeries will work if you have injured nerves or diseased and/or generalized damaged blood vessels. Also, if you are a candidate, be aware that vascular surgeries are still considered experimental by some urologists and may also not be covered by your insurance.
What can be expected after surgical treatment for erectile dysfunction (ED)?
Most of the best known treatments for ED have excellent track records for being both effective and safe. But in making your choice, make sure to discuss the potential complications of each option with your doctor.
For instance, the good news about a penile prosthesis is that it does not usually affect urination, sex drive, orgasm or ejaculation. But on rare occasions, these semi-rigid, silicone-covered rods or hydraulic devices can cause pain or reduced sensation. While injections can initiate erections within 15 minutes to several hours, be aware that they also can produce prolonged or painful ones, not to mention a scarring of penile connective tissue ( fibrosis ).
At the same time, a vacuum erection device should take only one to three minutes to give an erection, usually with no serious side effects if used properly. However, the use of the erection device to maintain the erection is limited to 30 minutes.
Sildenafil, tadalafil and vardenafil have nearly 80 percent success rates, primarily because they are a solution that works within one hour. But on occasion they can cause headaches, flushing, indigestion or muscle aches. Also, if you have heart disease or low blood pressure, the Food and Drug Administration (FDA) cautions a thorough examination before getting a prescription. You cannot take these drugs if you are taking nitroglycerine or any similar drug.
