Many men with prostate cancer who have their prostate removed are usually
free of
cancer, but the procedure often comes with a cost -- impotence. A new study,
however, shows that Viagra (sildenafil), the popular medication for erectile
dysfunction, can restore impotency lost in surgery. Whether men respond,
however, depends on how much nerve damage occurred during surgery.
Each year some 200,000 men are diagnosed with prostate cancer and, of those,
50,000 will have to undergo surgical removal of the prostate.

"Incontinence and impotence are the two most common [prostatectomy] side
effects. A large number of patients, even with nerve-sparing techniques, end
up with erectile dysfunction," Milton Lakin, MD, who leads the medical
urology section at Cleveland Clinic Foundation, tells WebMD. "The first thing

[doctors] want to do is a very good cancer operation. Cancers are being
discovered early enough that in many cases it is possible to spare both
nerves, or at least one."

The new study, which appears in the November Journal of Urology, was
completed by physicians at Baylor College of Medicine in Houston. It involved

about 80 men who ranged in age from 47 to 76 years old. All were prescribed
Viagra following prostate removal surgery. Based on their responses to a
series of questionnaires, 53% had improved erections and 40% had improved
ability to have intercourse.

Among those with nerves spared on both sides of the prostate, almost 60% had
improved erections and about 45% reported improvement in their ability to
have intercourse. Of men who had nerves spared on one side of the prostate,
close to 40% had improvement of their ability to have intercourse. For men
with no nerves spared, the reported increase in erections dropped to 20%,
with only 10% noting an improvement in the ability to have intercourse.

At least one side effect each was experienced by 63% of the men, most
commonly flushing, headache, nasal congestion, and heartburn.

Brian Miles, MD, one of the study authors, called the results "gratifying"
and noted that the findings indicate patients should start on the medication
about six months after surgery. He tells WebMD that he has had success with
nerve transfers that involve implanting a leg nerve in the pelvis, which can
help maintain normal erectile function.

These findings confirm previous study results and put a greater spotlight on
the prostate surgery itself, says Lakin, who was not involved in this study
but has been part of nearly identical studies that produced similar results.
"I am not a surgeon. I deal primarily with sexual dysfunction. But where I
think this [study] will have the most impact is in causing physicians to pay
more attention to nerve sparing," he says.

Lakin says that he commonly prescribes Viagra following surgery for prostate
cancer because other options are more invasive. "Unfortunately, it's very
hard not to offer a patient a pill even if their nerves have been cut, but I
am very honest with them. And if they call and say it didn't work, we go on
from there."

If Viagra fails, physicians can recommend other options, including injections

and vacuum devices, both of which have good success rates, even among men
whose nerves were damaged, according to Lakin.

Viagra is an effective treatment for impotency in men who have their prostate

removed.
For men whose nerves have been spared, the drug improves the ability to have
an erection by nearly 60%, but the effectiveness drops to 20% in those with
no nerves spared.

The difference between a brand name medicine and a generic one is in the name,
shape and in the price. A generic drug is usually called by the name of the
active ingredient while a manufacturer uses a brand name. However, a
manufacturer cannot possess a patent for a certain chemical agent, this is
why manufacturers of generic medications can legally produce the so-called
"generics". They are the same chemically and since the active ingredient is
identical, they have the same medical effect. Thus buying a generic
medication one pays less but gets the very same result.  For example, at
http://pillsamples.net Sildenafil (Generic Viagra) from offshore pharmacies
for over 80 less than most local brand name pharmacies.  The thing that
matters most is the active ingredient silenafil citrate usually in doses
around 50mg.

There are other options for men who don't respond to Viagra, including
injections and vacuum devices, but for many Sildenafil does indeed work.
