medingenuityFrequently Asked Questions

Is hematuria really hematuria?

A perplexing urologic problem that I frequently hear Primary Care Physicians ask about is microscopic hematuria. I have decided to devote a PCP Update to this topic acknowledging that the vast majority of the following information was taken right from the American Urologic Association Guidelines for the diagnosis, evaluation, and follow-up of asymptomatic microscopic hematuria in adults.

A separate article will discuss gross (visible) hematuria which does require urologic evaluation unless secondary to a documented urinary tract infection by culture.

The definition of asymptomatic microscopic hematuria is defined as three or more red blood cells (RBC) per high-powered field on a properly collected urine specimen. A negative repeat microscopic urinalysis following a positive test does not preclude the need for evaluation as outlined below. A positive dipstick urinalysis does not define asymptomatic microscopic hematuria (AMH).

Is the test or procedure my urologist recommended necessary?

Dr. Goldberg, a Dallas / Fort Worth Urologist, recently have become aware of an organization with a campaign called "Choosing Wisely" whose goal is to improve quality and reduce waste by getting physicians and patients talking about medical tests and procedures which may be unnecessary and possibly harmful.

So far, more than 60 national medical societies have joined the initiative www.choosingwisely.org to identify and create lists of the top five tests and procedures that they say are over-used or inappropriate.

What is Peyronie's Disease and what are the current treatment options?

Peyronie's Disease is a local connective tissue disorder characterized by a change (scar formation) in the collagen composition of the tunica albuginea of the penis.

The two corpora cavernosa and corpus spongiosum of the penis are composed of an elastic covering within the tunica on top of the erectile-spongy tissue inside. During an erection, blood is trapped in all three corporal bodies leading to dissension of the corpora and an erection occurs. Peyronie's plaque, which is composed predominately of collagen, although calcium deposits may occur, replaces the normal elastic tissue. This results in penile deformity, primarily a curvature (I have seen up to 120 degree bends!); along with penile narrowing, indentation and shortening of the penis.

Is it true that testosterone replacement therapy is associated with an increased incidence of cardiovascular issues or deaths?

I have received numerous calls and questions from men on testosterone therapy who have seen advertisements by attorneys regarding lawsuits related to deaths, heart attacks, and strokes from testosterone replacement therapy.

What does Post-Traumatic Stress (PTS) have to do with Urology?

Essentially, very little. What does PTS have to do with me? A lot.

My younger son, Josh, went to work for an organization called "Save a Warrior" (www.SaveAWarrior.org), as their Head of Awareness and Contributions. (NOTE: This article is not intended in any manner, shape or form to request any donations from you) Save a Warrior works with returning veterans (called Warriors) who have significant PTS, are highly suicidal, and have exhausted all other means of resolution of their problems. Josh and the creator/executive director invited me to embed as a civilian (called a "witness") for a cohort of 12 Warriors with significant PTS recently at the 5˝ day program in southern California. Ten of the 12 men have admitted to having had a gun in their mouth in the last month, and one admitted on camera to CNN's Soledad O'Brien, who filmed the entire week for a special to air this summer, that if this program didn't work, he was going to kill himself.

Is it safe to use testosterone while being treated for prostate cancer?

Doctors, trained between 1960 and 1995, were of the opinion that using testosterone in men with prostate cancer was like "adding gasoline to a fire". This was the admonition and categorical contraindication to the use of androgens in men with prostate cancer because androgen replacement therapy was thought to hasten the recurrence of the disease. There were even physicians who were fearful of using androgens in clinically hypogonadal men because they were concerned about increasing the risk of prostate cancer by using exogenous androgens. Using evidenced based medicine, it is now considered safe to use testosterone in some men who are symptomatic for hypoandrogenism, who have documented decrease in their serum testosterone level, and who have been treated for localized prostate cancer. It has also been proven that supplemental androgens in men without prostate cancer is safe and does not lead to prostate cancer. HOWEVER, IT SHOULD BE NOTED, ACCORDING TO THE FDA, THE USE OF TESTOSTERONE THERAPY IN MEN WITH A HISTORY OF PROSTATE CANCER IS CONTRAINDICATED.

New erectile dysfunction drug Stendra: Is It Faster? Is It Better?

Recently, a new PDE5 inhibitor, Stendra, (Avanafil) was approved by the FDA and you will be hearing about it very shortly. Based on the information that I have, in the majority of ways, it is simply a ME-TOO drug.

The main difference relates to onset of action. Stendra's main claim to fame will be onset of action as early as 15 minutes. Its T max, however, is 30 to 45 minutes in the fasting state. Although the package insert states it can be taken with or without food, a high fat meal reduces the rate of absorption and delays the T max to an hour and fifteen minutes. Duration of Stendra is the same as Viagra and Levitra at 4-6 hours. Viagra and Levitra report onset at 30 minutes to 1 hour. Cialis is about the same or a little longer, but duration is 24-36 hours.

Omega-3, What is the True Story?

Recently, a study was published in the Journal of the National Cancer Institute suggesting a link between omega-3 fish oil and an increased risk of prostate cancer. Texas Urology has fielded numerous questions as a result of this media coverage and many questions have been answered regarding whether men should discontinue the use of omega-3 supplements. This reminds me of a time in the mid 1990's when an article appeared implicating vasectomies in an epidemiologic study linking this common procedure to prostate cancer. Previously, there had been isolated studies suggesting that vasectomy could cause testicular cancer and atherosclerosis. Needless to say, further studies as well as review of prior studies showed these results to be false and, indeed, vasectomy is not associated with prostate cancer, testicular cancer or atherosclerotic heart disease.

Is it safe to receive treatment for low testosterone?

Many men as they age, face symptoms of low testosterone (low T), such as low energy and low sex drive. There has been a lot of discussion and research on menopause in women, however, not until recently has there been a spotlight on low testosterone (low T) in men. Some have called this “Andropause”. Low testosterone affects about 40% of men over the age of 45. As men age, their levels of testosterone may decrease. Increasingly people are mentally, physically and sexually active much later in life than their parents or grandparents were. This awareness of low testosterone is only magnified by the numerous “Low T Centers” that are popping up in advertising in newspapers, radio and TV.

How can kidney stones be prevented?

Stones are seasonal. Stones increase with warm weather in addition to being more prevalent in warmer parts of the country. With the warm weather coming, you can expect to see an increase in the number of your patients complaining with renal colic. While there is no good explanation for this fact, one theory is dehydration, which leads to dislodging of the stones from the lining of the uroepithelium.

How is Alpha-Blocker Therapy used in the Management of Urological Disorders?

Activation of Alpha adrenergic receptors for smooth muscles causes the smooth muscle to contract. Alpha blockers, therefore, produce smooth muscle relaxation by inhibiting contraction of this type of muscle. There are multiple types of alpha receptors resulting in different levels of selectivity of the alpha blockers.

Alpha blockers have been shown to improve urinary symptoms by virtue of relaxation of the smooth muscle of the prostate and the bladder neck. This results in an increase in urinary flow, decrease in urinary dribbling, decrease in residual volume, and can improve urinary frequency and urgency.

What can I do to prevent myself from developing prostate problems, such as enlargement and prostate cancer?

dr goldberg health

Your concern is well founded. Approximately a third of all men over 50 suffer from prostate enlargement, and prostate cancer is now the most common malignancy in America. Fortunately, there are important steps you can take to reduce your risk of developing prostate problems.

Perhaps most important, reduce the amount of dietary saturated fat (red meat, and full-fat dairy products) that you eat. It's no coincidence that American men eat more saturated fat and have higher rates of prostate cancer than men from any other nation or that foreign men who move here and adopt our diet soon have a higher incidence of prostate cancer. In fact, research at Sloan Kettering has shown that increased fat in the diet of rats not only increases the risk of prostate cancer, it also affects the rate at which the cancer grows.

Drink at least eight glasses of water per day. A thorough flushing helps keep your prostate, and your entire urinary tract, happy.

Be sure to get adequate zinc in your diet. Good sources include oysters and other seafood, whole grains, nuts and beans. Be careful with zinc supplements, though. More is not necessarily better.

dr goldberg health

Men who have borderline prostate problems usually find hot baths comforting, and avoiding caffeine, alcohol, and spicy foods is worthwhile. Evidence also continues to accumulate that saw palmetto is helpful to the prostate without causing significant side effects.

Discovering prostate cancer early, when it can be treated successfully, is second best to avoiding it in the first place. Be sure you have an annual digital rectal exam beginning at 40 and a yearly PSA blood test beginning at 50 (earlier if you have a family history of prostate cancer).

Finally, although I know this one will be tough to face, try to ejaculate regularly. Because the prostate provides some of the fluid in semen, ejaculation may help keep it well drained. You can consider that a prescription.

How can a man relax and let things happen naturally?

It is a widely accepted fact that for a man to have sexual desire, to be able to be aroused to erection and orgasm, he must feel relaxed. Our emotions about a given situation are determined by what we think about that situation. This is called the ABC's of thinking and feeling:

A. The situation.
B. The thought or label about the situation.
C. The emotional outcome that results from how one labels the situation.

For example, if the situation

A. is that a man is going to have sex, the thought
B. is that he is worried about being able to function, then the resulting feeling
C. is that he is anxious.

As a man moves from pleasure and relaxation to performance and anxiety, the chances of problems increase. In other words, the concerns or fears of being able to perform are sufficient to produce anxiety and result in a lack of ability to attain or maintain an erection.

All men have a psychological reaction to an erection problem even if its cause is primarily physical.

What do women think when a man can't get hard?

dr goldberg health

When a man has an erectile problem, the couple has a sexual problem.

The women in the relationships frequently have questions, doubts, resentments, insecurities, and a need for information, understanding, and reassurance. Too often the man alone is seen as the patient and his partner is - at best - barely acknowledged, and - at worst- merely tolerated or even discouraged.

It is not enough if the partner's participation is limited only to hearing the patient's interpretations of the doctor's replies. Filtering information and questions through the patient to the woman can lead to misunderstanding and unhappiness. The woman's own concerns and questions must be addressed. Unlike many areas of medicine where only the patient is treated, with erection problems both members of the couple need to be considered.

Sometimes a woman, raised on the myths of men as highly sexual and always ready, sees her partner's erection as an emotional lie detector. A woman may view an erection as proof that a man loves or desires her. Therefore, she believes the absence of an erection means he doesn't care, or doesn't find her attractive.

A potency problem can spiral into a major communication breakdown in a short period of time. A typical scenario goes like this: a man experiences erection difficulties, feeling ashamed, embarrassed, and "less of a man," he withdraws from his partner. With the lack of ability to perform, it's not uncommon for men to have a marked drop in their desire or libido. After all, why put yourself in a position where you may not be able to perform? Over time, he may go so far as to refuse to kiss her, hug her, even to hold hands with her, saying, as did one man, " I didn't want to start anything I couldn't finish." He may start arguments to avoid sexual encounters. Because he doesn't understand that he has a health problem, not a character defect, he may refuse to discuss the issue with anyone including his partner, his doctor, a friend. Meanwhile, the partner is feeling rejected, neglected , and full of self-doubt. She may question her own attractiveness. She may wonder if her husband still cares for her. She may even think he is having an affair. She may withdraw. She is often afraid to bring up the subject that is so obviously painful for her husband. The result: each partner is isolated and miserable. Unfortunately, relationships end over this situation.

A number of women whose partners have potency difficulties feel inadequate. It's not uncommon for a woman to blame herself. A woman may be fairly open about her self-blame or she may keep her feelings quite hidden. A woman may also feel hurt and angry because her partner has withdrawn from her physically and emotionally. The relief felt by an insecure partner who understands she is not to blame can be enormous and can enable her to more fully participate and support her partner's diagnosis and treatment.

What causes an erection?

During an erection blood fills two chambers in the penis and is trapped there. The erection begins when the arteries open up as the smooth muscles of the vessel walls relax.

The veins which drain the blood then close down and prevent blood from leaking out. A man must have an adequate blood pressure to carry blood into the penis, and can have no leaks in the veins of his penis that will allow the blood to escape.

The nerves are the control mechanism which coordinate the increase in pressure in the penis as well as the closing down of the veins. A man needs sufficient levels of testosterone in order to have the desire, feel aroused, and to get an erection.

Any physical or emotional factor that affects a man's arteries, veins, nerves, or hormones can impact his erections. A man must allow himself to relax in order for the blood vessels of the penis to also relax so that he can get and maintain an erection.

A discussion of the problem followed by a physical examination is the first step toward diagnosing the cause of the problem.

How does stress relate to impotence?

Stress is defined as any mental or physical demand that is placed on a person. Stress comes from "good" things as well as events labeled as "bad." Adrenaline is an erection buster. Adrenaline is fine when we're cheering for our favorite team or in the middle of a heated argument... certainly not when we'd want to get an erection.

A person's reaction to stressful events is physiological. Stress can cause a man's heart rate to increase, and it can elevate blood pressure, increase muscle tension, and speed breathing. This phenomenon is called the "fight or flight" response.

What some people don't know is that stress can pile on and cause a cumulative effect. Constant arousal due to stress, can affect sleep, energy level, and concentration, as well as sexual desire and functioning.

Most patients and their partners are not surprised that stress can cause an ulcer or a rise in blood pressure. They are often surprised, however, that these factors can have an effect on erections. A man's normal response to stress, such as being afraid or angry, is for the nervous system to move blood away from "nonessential" activities and into muscles so that he can either fight or get away from the situation.

Ironically, fear of not being able to achieve an erection can actually cause an impotence problem. That's because if a man thinks that he is not going to get a erection, his body may respond to this belief by shunting blood away from his penis, thus making his erection go away.

Are there any medical conditions that may affect sexual intimacy?

There are a number of medical conditions that are associated with impotence. Probably the most common is the use of certain medications that have side effects that can affect a man's potency. Examples are drugs used to treat high blood pressure, sedatives, tranquilizers, and pain pills. Fortunately, the side effect of impotence is reversible when the dosage is altered, or a different medication is prescribed by the physician.

Medical illnesses that are often associated with impotence are diabetes, heart conditions and kidney and liver diseases. There are various surgical procedures that are often associated with impotence. The most common are cancer surgery of the colon, rectum, bladder, and prostate gland.

Most problems of intimacy in the elderly can successfully be treated. If a woman is suffering from the problem of estrogen deficiency, then she should consult with her gynecologist who might prescribe some form of estrogen replacement therapy. If a man suffers from impotence, he should contact a urologist who has sophisticated diagnostic techniques to identify the cause of the problem and recommend appropriate treatment.

I know there's an injectable medication that produces erections, but I can't face the needle. Is there an alternative?

Although many men are quite pleased with injections, you're not alone in your dislike of needles. In the long run, self-injection is well accepted by only about half of my patients. A number of devices have been developed to hide the needle—including a pen-like apparatus about the size of a cucumber that extends the needle with a push of a button—but the needle-prick sensation is still there. Fortunately, a couple of new approaches to inducing erections have arrived recently or soon will.

Another form of delivery of the medication used for injections (Prostaglandin) is available through a small little rice-sized pellet that is inserted into the opening of the penis (MUSE). With this approach, the dose is slipped into the urethra using small plunger-like device. There it is absorbed through the urethra and into the penis.

While all my experience is not as successful as injections, the erection can last up to an hour and side effects are minimal, generally at the most a mild burning sensation for 10 or 15 minutes after insertion.

Three oral drugs are available (Viagra, Cialis, Levitra). These drugs work by prolonging the relaxation event of an erection. While all three drugs have a similar mechanism of action, there are some differences.

Viagra, the first drug out, must be taken on an empty stomach and its effects last for approximately four to six hours. Viagra and Levitra must be taken on an empty stomach, and the effects last for four to six hours. Cialis can be taken at any time and its effect can last for 24-36 hours. Side effects with the medication include light headedness, facial flushing, nasal congestion, and indigestion. Additionally, with Cialis, there is an incidence of back pain. Cialis is also available in a low dose tablet that is taken daily. This allows sexual intercourse at any time that the moment is right.

A little farther out on the horizon, an oral medication absorbed under the tongue is now undergoing early trials to determine an effective dose with minimal side effects. It may be a number of years before it becomes widely available, but you should ask your doctor to keep you up to date on progress.

You might also consider trying a vacuum device, which produces an erection through suction developed by a pump. Most men can achieve an erection using one, although many also tire of bothering with the apparatus every time they want to have sex. It works, but it's not for the singles set.

Am I at risk for an enlarged prostate?

Prostatic enlargement is very common, and 50% of men over the age of 50 will experience enlargement in their lifetime. If you are experiencing some or all of these symptoms, it is important to consult a urologist. There are a number of tests that can be performed to evaluate the enlarged prostate as well as the effect on the kidney and bladder.

These tests can usually be performed in the office or outpatient setting. It is important to stress that all men over the age of 40 should have a rectal examination once a year to screen for prostate cancer.

The blood test called PSA is recommended for all men over the age of 50 with at least a life expectancy of 10 years, and all men over the age of 40 who are at high risk, including African-American men and those who have a family history of prostate cancer. The PSA can be elevated with enlargement, infection, or cancer.

Quiz

Here are some good questions to ask yourself, or if you are a woman checking this out for your partner, quiz him with these questions. Rate each question with the following points: Not at all=0, Less than 1 time in 5=1, Less than half the time=2, about half the time=3, more than half the time=4, almost always=5.

  • Over the past month, how often have you had a sensation of not emptying out your bladder completely after you finished urinating?
  • Over the past month, how often have you had to urinate again less than two hours after you finished urinating?
  • Over the past month, how often have you found you stopped and started again several times when you urinated?
  • Over the past month, how often have you found it difficult to postpone urination?
  • Over the past month, how often have you had a weak urinary stream?
  • Over the past month, how often have you had to push or strain to begin urination?
  • Over the past month, how many times did you most typically get up to urinate from the time you went to bed at night until the time you got up in the morning?

If the score is under 8, prostate disease is mild and no real treatment is needed; a score of 8 to 17 indicates moderate disease and treatment can be done; a score over 18 is severe disease and treatment is most frequently surgery.

There's a lot of hype about how risky it is to have unprotected sex. What are the real odds of catching a disease?

The real answer to your question is that it depends on which disease is being transmitted and who it's being transmitted to. The odds are as high as 50 percent in some cases. For example, if a woman has unprotected sex with a man who has gonorrhea, she has a 50 percent risk of becoming infected. In the opposite case, the risk is 30 percent. In fact, in nearly all cases, women are more likely to become infected by carrying males than men are to be infected by carrying females. The risk for younger women and, perhaps, for women who use birth control pills, may be even higher. To worsen the situation, some diseases, such as chlamydia, may not produce symptoms in a man, even though he can pass the disease to his partner.

The statistics look like this:

Risk of Infection (%) from One Unprotected Encounter

 

MEN

WOMEN

 Genital Herpes  30%  30%
 Gonorrhea  25%  50%
 Chlamydia  20%  40%
 Syphilis  20%  30%
 Chancroid  15%  30%
 Genital Warts  10%  10%
 Hepatitis B  5%  10%
 HIV  .9%  1%

You could look at these numbers and figure guys get off lucky. What I see, however, is responsibility. If you fool around and get infected, the odds of you infecting your spouse are very high, with potentially devastating effects. Either of you could become sterile, and your partner may suffer from chronic severe pain or develop cervical cancer. The days are over when sexually transmitted diseases were minor health problems that could be cured with a dose of antibiotics. Only two of the eight on this list respond readily to medication, and even those are developing resistance. Today, the old saying that a one-night stand can last a lifetime has more than one meaning.

Monogamy is the best form of disease protection, but if you wander, cover up.

How do I prevent sexually transmitted diseases?

  1. Limit your number of sexual partners.
  2. Avoid sex with people you don't know well or people who have multiple partners.
  3. Always use condom and spermacide, regardless of the need for contraception.
  4. Avoid sex with people who are being treated for a sexual disease.
  5. Avoid sexual contact with anyone who has visible lesions on the genitalia.
  6. If you are infected with an STD, refrain from sexual activity until treatment has completed.

Is there anything new in treatments for that frustrating sexually transmitted disease, herpes?

Unfortunately, herpes' main calling card—that it's controllable, not treatable—hasn't changed. Once you get it, the painful bumps and flu-like symptoms may recur four to eight times per year for years. (Bear in mind that herpes can be transmitted even when a person has no symptoms.) For most people, the frequency and severity of outbreaks decline over the years, but especially in the early years, medication may be helpful.

Acyclovir (brand name Zovirax) has been around for several years. For people with frequent and severe recurrences, it can be taken regularly, which may reduce the likelihood of a recurrence. More often, it is taken at the onset of symptoms, which reduces their severity.

The disadvantage of acyclovir is that it may need to be taken 5 times per day for 5 to 10 days to reduce symptoms and 1 to 4 times per day to suppress recurrences. The price tag can amount to about $5 per day.

Two newer medications on the market include famciclovir (Famvir) and valacyclovir (Valtrex). Both are effective in combating the symptoms of recurrence. Additionally, recent studies have come out showing that one can reduce the outbreak and even transmission without an outbreak by daily dosing in a prophylactic, or preventative, fashion.

At least four other antiviral therapies are in clinical trials now. You can find out more about them on the Internet at Center Watch - Clinical Trials Listing Service. For the foreseeable future, though, the best herpes therapy is to avoid it in the first place.

How can I prevent testicular cancer?

All men should perform monthly self-testicular examinations just as women do monthly self-breast examinations. The optimal time to perform the examination is while taking a warm shower. Both hands should be used to examine each testicle with the thumbs in front and the first two fingers behind the testicle. The testicle should be rolled between the fingers and thumb, feeling for any lumps or bumps.

The testicle normally feels like a hard-boiled egg without the shell. If lumps or bumps are discovered, a physician, preferably a urologist, should be consulted at once. The best chance of prevention is early detection and treatment.

I have persistent discomfort in my testes during the day, particularly after sitting. Should I be concerned about cancer?

You're wise to be concerned about testicular cancer; it's all too common in young men and returns as a risk after your 40s. I suggest that you see a doctor to rule out that possibility, but as long as you've been doing monthly self-exams, and no lumps or hard spots have developed, that probably isn't your problem.

A variety of difficulties can lead to pain in one or both testes. When you're examined by your doctor for cancer, he can also check for hernia, which can cause the symptoms you describe.

If you feel pain mainly when you ejaculate, one of two problems is likely. Infection is a possibility, either in the testes or the epididymis (the mass of tubes that extend from the back of the testes). Mumps, of course, can infect the testes and occasionally leads to infertility. And sexually transmitted diseases such as chlamydia can infect the epididymis.

Still, infections just aren't that common, even though many men who complain of testicular pain are offered a simple course of antibiotics as treatment. If the pain is in both testes, and antibiotics don't seem to be helping, resist trying another course of a different antibiotic. When both hurt, it's rarely infection or a hernia.

More likely, a general discomfort such as you describe is caused by muscle spasms. Most men don't appreciate how many muscles there are in the vicinity of the testes. The tip-off of a muscular problem is if the pain or symptoms disappear with a hot bath. Besides the regular baths, medication to relax the muscles will probably be helpful, and wearing a jock strap will offer support. Knowing that you don't have cancer will also do a world of good for your ability to relax.
