Dr. Cornell is a board-certified urologist practicing in downtown Houston, Texas.
He completed his residency training at Baylor College of Medicine in the Scott Department
of Urology and his general surgical training in the Michael E. DeBakey Department
of General Surgery.
Prosthetic Urology Specialist
Dr. Cornell is respected as one of the nation's foremost prosthetic
urologists. He specializes in placing both the three-piece inflatable penile implant
and artificial urinary sphincter (AUS) through a single scrotal incision in a single
Adenocarcinoma of the prostate is the clinical
term for cancerous tumor of the prostate. Prostate cancer confined to the gland
is usually curable. According to the American Cancer Society (ACS),
Vasectomy represents the
most definitive form of male contraception. This 10-15 minute procedure is usually
completed in the office under local anesthesia without the need for a scalpel incision.
This "no-scalpel" technique permits access to each vas deferens-the tube
carrying sperm from the epididymis/testis to the urethra-through

Over 30 million people in the United States suffer from urinary incontinence or
overactive bladder (OAB). This condition is far more prevalent in women than men.
In the general population, age 15 to 64 years, 10-30% of women, versus 1.5% of men
are affected. Those with OAB often experience
BPH - Benign Prostatic Hyperplasia
BPH is not simply a case of too many prostate cells.
Prostate growth involves hormones, occurs in different types of tissue (e.g. muscular,
glandular), and affects each man differently. Because of these differences, treatment
will vary in each case.
Post-prostatectomy urinary incontinence (PPI) is the involuntary leakage of urine
following radical prostatectomy to treat prostate cancer. PPI represents a specific
form of stress urinary incontinence where increased abdominal pressure from a cough,
sneeze, or simple physical straining results in the leakage of urine
Kidney stones are one of the most common
disorders of the urinary tract. It is estimated that 10 percent of all people in
the United States will have a kidney stone at some point in time. Men tend to be
affected more frequently than women

"Inflatable Penile Prosthesis - very successful"
– Tim - Orange, Texas
"It works very well with no side effects and doesn’t impede on any of my activities.
It is much easier and less stressful to go on with intimate life after prostate
surgery with this implant. I am very pleased with this implant and feel it was the
best option as opposed to other choices for ED out there. I feel very confident
that if I were to experience any problem with it Dr. Cornell would be able to solve
it. I would definitely recommend this implant and Dr. Cornell to any friend or family."
"Dr. Cornell put me at ease immediately, which made me very comfortable discussing
my erectile dysfunction and PE problems with him. I did not feel hurried and was
very satisfied with the multiple options presented."
– Bill - Humble, Texas
"I have complete confidence in Dr. Cornell and the recommended treatment. I will
gladly recommend Dr. Cornell to my friends and family."
"I recently had surgery to solve a years old erectile dysfunction problem I have
endured. Dr. Cornell listened to all the facts, ran some tests,and offered multiple
solutions. I chose the surgery option for a penile prosthesis. Yesterday, I had
my one month follow-up visit. I am extremely pleased with the results and wish that
I had done it years earlier. Dr. Cornell is extremely knowledgeable, highly trained,and
I believe to be an expert in his field. I HIGHLY RECOMMEND HIM."
– M. C. - Houston, Texas
"I am an internal medicine physician practicing in rural Maine. One of my patients
recently came to me complaining of erectile dysfunction and urinary issues related
to prostate cancer. This patient wanted to go the best urologist in this field regardless
of geographic location. Although there would be many miles to travel, there was
only one urologist I trusted to deal with these issues, Dr Robert Cornell."
– Dr. Stephen J. Goss
"Dr Cornell is the best in the country and his expertise is unparalleled. But perhaps
equally important, he puts the patient first. He is compassionate, empathetic and
caring. My patient felt immediately at ease and appreciated the personalized one
on one attention given by Dr. Cornell. Such attention, unfortunately, is becoming
more and more infrequent in today's medical climate. The people in Texas are very
fortunate to have such a resource."
"I will continue to recommend my patients make the trip to Houston to get the very
best specialized urologic services available today."

in his field."
"I had successful IPP surgery in 2011. While it does take a little time to get use
to the implant, I am glad I had the surgery. I no longer have to take pills that
sometimes did not work. The device works every time I choose to use it."
– Marion H. - Deer Park, Texas
"If you are having trouble with ED, I strongly urge you to check into the IPP solution.
Dr Cornell did a great job. I recommend him to all my friends who have ED problems."
"I was very happy with the service that Dr Cornell provided. I felt that he did
not rush me into prosthetic surgery without trying other methods first. Additionally,
he discovered my cancer and made sure that was taken care of first. The surgery
was very successful and I can now live a fulfilling life..."

Bladder and an enlarged Prostate. I was impressed with the level of help given to
– Al B. - Houston, Texas
"I highly recommend Dr. Cornell, MD, PA and his staff..."
"Back in January I had a procedure done that I really needed to have done. I talked
it over with Dr. Robert Cornell and an appointment was scheduled right away."
– L. Nieto - Houston, Texas
"I feel like a new person thanks to the expertise and knowledge of Dr. Cornell.
I definitely recommend him to anyone who has a neurological need."
"I have been listening to Dr. Cornell on the radio for several years. I am glad
that he took the time to do [the radio shows]. When I developed prostate problems,
incontinence and erectile dysfunction I knewDR. Cornell could help. When I visited
Dr. Cornell, he promised me that he could take care of my problems. He did just
that. I can now do something that I have not been able to do in 3 years, I can again
urinate like normal people do. My days of leakage are over; my days of impotency
are over. There should be a 'Dr. Cornell Day!' Thank you!"
– A. Johnson - Houston, Texas
"There was a time when I was depressed after my prostate surgery in March 2010.
I didn't feel like a complete man. On November 18, 2013 Dr. Cornell changed that
for me with an implant and a urinary sphincter. To his credit I have become me again."
– Richard H. - Houston, Texas
"Dr. Cornell....I just wanted to say thanks in a 'BIG' way for your kindness and
excellent care you and your staff gave me before and during my surgery. Because
of your knowledge everything went well! Continue the good work."
– Luther N. - Houston, Texas

Adenocarcinoma of the prostate is the clinical term for cancerous tumor of the prostate.
Prostate cancer confined to the gland is usually curable. According to the American
Cancer Society (ACS), prostate cancer is the most common type of cancer in men in
the United States. The ACS estimates that about 192,280 new cases will be diagnosed
in 2009 and about 27,360 men die of the disease. Prostate cancer is the second leading
cause of cancer death in men, exceeded only by lung cancer. Prostate cancer occurs
in 1 out of 6 men, with reports of diagnosed cases rising rapidly in recent years
and mortality rates declining, likely due to increased screening.
Cornell in the operating room. Treatment for prostate cancer
depends on the stage of the disease at diagnosis and the patient's age and overall
health. Elderly patients with early stage cancer or co-existing illness may be treated
conservatively. The different treatment options I provide include:
The prostate biopsy procedure is the main method used to diagnose prostate cancer.
In obtaining a biopsy, your physician performs a surgical procedure using a very
thin needle to remove small pieces of prostate tissue from your prostate gland.
The tissue collected by the needle is then sent to our diagnostic laboratory for
microscopic examination - to evaluate your prostate health - with a particular focus
on identifying the potential presence of cancer cells. The pathologist performs
the microscopic evaluation. If cancer cells are discovered, the pathologist can
assist us in determining the stage and extent of the disease process. Ultimately,
our goal is to form a unique plan for your future treatment needs.
Until recently, detecting cancer in your histological specimen (prostate biopsy)
was limited to what could physically be seen when looking at the specimen under
a microscope. Because a biopsy is only a 1%-2% representation of the overall volume
of the prostate gland, and because cancer can present as a small lesion anywhere
in the prostate, a common fear is that the biopsy needle may miss a cancerous lesion
- leaving behind a hidden (occult) tumor that could possibly evolve into a worsening
problem. There is new technology - a test called ConfirmMDx - that addresses this
fear. Results of the initial biopsy usually take about a week, and the ConfirmMDx
test usually return in an additional 1 to 2 weeks, mainly because the test is only
utilized if cancer is not seen under the microscope.
The new test offers valuable information because it extends our detection abilities
so we can locate cancer beyond the point of the histological specimen - by millimeters
or centimeters from each core (biopsy zone in the prostate) - giving us the ability
to project our detection capabilities across almost the entire organ. It does this
by detecting a field effect of epigenetic signatures that are unique to prostate
cancer (hypermethylation in CaP - specific genes RASSF1, APC, and/or GSTP1). If
these signatures are not detected, it gives us the added assurance that your prostate
is free of cancer (at least a 90% negative predictive value with this assay). Conversely,
if a field effect is detected, these signals will give us valuable information to
use in a focused re-biopsy: potentially giving us a timely advantage and greatly
improving our chances to find, characterize, and develop a specific plan to deal
with prostate cancer if, again, it exists.
Two types of radiation therapy are used to treat prostate cancer: brachytherapy
and external radiation therapy (XRT).
This treatment involves implanting tiny radioactive capsules (called "seeds")
into the cancerous prostate. The seeds emit radiation that kills cancerous tumor
cells. Men with small tumors confined to the prostate (stage T1 or T2) and those
with only moderate prostate enlargement are candidates for brachytherapy. The procedure
is performed on an out-patient basis and takes 45-60 minutes. Brachytherapy patients
usually resume routine activity within a day or so. For those who additionally have
obstructive voiding symptoms, transurethral resection of the prostate (TURP) surrounding
the urethra may be performed before brachytherapy is initiated.
Radiation Treatment (XRT)
XRT is recommended as an alternative to surgery for cure of disease confined to
the prostate. XRT is usually given on an outpatient basis for 6-8 weeks. High energy
x-rays are projected into the prostate tissue from a machine outside the body. The
radiation destroys cancer cells and shrinks the tumor.
Hormonal therapy for prostate cancer involves the use of medication to block production
of testosterone, which prostate cancer cells use to grow. Drugs used for hormonal
Vantas®, Eulexin®, and Viadur®.
Radical retropubic prostatectomy is the "gold standard" treatment for localized
prostate cancer. Radical prostatectomy is the surgical removal of the prostate and
surrounding tissues, including the seminal vesicles and pelvic lymph nodes.
Good candidates for prostate cancer surgery have one or more of the following characteristics:
- Generally good health
- Tumor confined to the prostate gland (Stage T1 or T2)
- Age under 70 years
- Life expectancy greater than 10 years
Radical retropubic prostatectomy involves an incision in the lower abdomen. This
gives the surgeon access to the prostate, seminal vesicles, and the pelvic lymph
nodes. Based on findings intraoperatively and the tumor volume anticipated from
the number of positive biopsy cores done before surgery, every attempt is made to
save the cavernosal nerves to the penis (nerves providing erection/potency). This
maneuver adds little time or complexity to the case and can be offered by most recently
trained urologists today, including myself.
DaVinci Robot-Assisted Laparoscopic Prostatectomy
Robot-assisted prostatectomy is a minimally invasive, robotic-assisted surgical
procedure that removes the cancerous prostate gland.
Typically, patients remain in the hospital for 2 days after surgery and are catheterized
for 7 days postoperatively.
The 10 year survival rate after radical prostatectomy ranges from 75% to 97% for
patients with well and moderately differentiated cancer and 60% to 86% for patients
with poorly differentiated cancer.
When cancer is confined to the prostate, the disease is usually curable with erectile
function and urinary control being salvaged in the vast majority of patients.
