Chris Dewald: Hematuria/CAT scan

This is part two on a continued series when faced with blood in the urine. I was then prescribed to take a more intensive exam under a CT instrument, also known as CAT or computerized axial tomography. According to radiologyinfo.org, CT scanning—sometimes called CAT scanning—is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

CT scanning combines special X-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body. These cross-sectional images of the area being studied can then be examined on a computer monitor, printed or transferred to a CD.

CT scans of internal organs, bones, soft tissue and blood vessels provide greater clarity and reveal more details than regular x-ray exams. Using specialized equipment and expertise to create and interpret CT scans of the body, radiologists can more easily diagnose problems such as cancers, cardiovascular disease, infectious disease, appendicitis, trauma and muscleoskeletal disorders.

CT imaging is one of the best and fastest tools for studying the chest, abdomen and pelvis because it provides detailed, cross-sectional views of all types of tissue often the preferred method for diagnosing many different cancers, including lung, liver and pancreatic cancer, since the image allows a physician to confirm the presence of a tumor and measure its size, precise location and the extent of the tumor’s involvement with other nearby tissue.

The examination plays a significant role in the detection, diagnosis and treatment of vascular diseases that can lead to stroke, kidney failure or even death. CT is commonly used to assess for pulmonary embolism (a blood clot in the lung vessels) as well as for abdominal aortic aneurysms (AAA). It is invaluable in diagnosing and treating spinal problems and injuries to the hands, feet and other skeletal structures because it can clearly show even very small bones as well as surrounding tissues such as muscle and blood vessels.
 

How should I prepare?

You should wear comfortable, loose-fitting clothing to your exam. You may be given a gown to wear during the procedure.

Metal objects, including jewelry, eyeglasses, dentures and hairpins, may affect the CT images and should be left at home or removed prior to your exam. You may also be asked to remove hearing aids and removable dental work.

You may be asked not to eat or drink anything for several hours beforehand, especially if a contrast material will be used in your exam. You should inform your physician of any medications you are taking and if you have any allergies. If you have a known allergy to contrast material, or “dye,” your doctor may prescribe medications to reduce the risk of an allergic reaction.

Also inform your doctor of any recent illnesses or other medical conditions, and if you have a history of heart disease, asthma, diabetes, kidney disease or thyroid problems. Any of these conditions may increase the risk of an unusual adverse effect.

Women should always inform their physician and the CT technologist if there is any possibility that they are pregnant.
 

What does the equipment look like?

The CT scanner is typically a large, box like machine with a hole, or short tunnel, in the center. You will lie on a narrow examination table that slides into and out of this tunnel. Rotating around you, the x-ray tube and electronic X-ray detectors are located opposite each other in a ring, called a gantry. The computer workstation that processes the imaging information is located in a separate room, where the technologist operates the scanner and monitors your examination.
 

What will I experience during and after the procedure?

CT exams are generally painless, fast and easy. With helical CT, the amount of time that the patient needs to lie still is reduced.

Though the scanning itself causes no pain, there may be some discomfort from having to remain still for several minutes. If you have a hard time staying still, are claustrophobic or have chronic pain, you may find a CT exam to be stressful. The technologist or nurse, under the direction of a physician, may offer you a mild sedative to help you tolerate the CT scanning procedure.

If an intravenous contrast material is used, you will feel a slight pin prick when the needle is inserted into your vein. You may have a warm, flushed sensation during the injection of the contrast materials and a metallic taste in your mouth that lasts for a few minutes. Some patients may experience a sensation like they have to urinate but this subsides quickly.

If the contrast material is swallowed, you may find the taste mildly unpleasant; however, most patients can easily tolerate it. You can expect to experience a sense of abdominal fullness and an increasing need to expel the liquid if your contrast material is given by enema. In this case, be patient, as the mild discomfort will not last long.

When you enter the CT scanner, special lights may be used to ensure that you are properly positioned. With modern CT scanners, you will hear only slight buzzing, clicking and whirring sounds as the CT scanner revolves around you during the imaging process.

You will be alone in the exam room during the CT scan. However, the technologist will be able to see, hear and speak with you at all times.

With pediatric patients, a parent may be allowed in the room but will be required to wear a lead apron to minimize radiation exposure.

After a CT exam, you can return to your normal activities. If you received contrast material, you may be given special instructions

I had my appointment at my the area hospital know as Augusta Health Center in Fishersville, Virginia. I had an expert staff attend to my needs from reception to the CT Staff. When I was brought back to the prep room, I was administered an intervenous line for the specialized dye. This was painless as it was done with precision and care.

Please read how to dress. If weather permits, wear a pair of pull on shorts or a bathing pair of trunks for problems as I have. This eliminates the need to put on those wacky gowns where your leaves your fanny perpendicular exposed. The test did not last more than 15 minutes. If you have ever been in for an MRI, this is a piece of cake. The CT scan looks like a cake donut that your body can enter. No closed in feeling was experienced as you can see daylight within reach.

I did receive the news that I do not have cancer, but do have kidney stones in each kidney that are too large to leave their respective growth areas. It seems to have aggravated the surrounding tissues and being on a medication to thin my blood, causes me to bleed internally.

The next step will be a trip to the urologist for the final determination of disposal. Join me again on that venture. Thanks.

Chris DeWald: Hematuria

Welcome to my world and join me on another adventure and educational trip. Hello, readers, and those in the need to know. I have been feeling poor lately with various symptoms that first led to my brain stem stroke. My most recent MRI revealed that my basilar and vertebral artery are void of flow. So I am a walking typing zombie right now. OK, I know, what’s new.

My GP has been doing and excellent job managing my vascular disease, but it was time for me to go to the Veterans Clinic in Harrisonburg for my yearly inspection. Part of this examination was a urinalysis administered by this clinic. The results showed that although it was a clear sample, I had microscopic red blood cells in my urine. What had the government doc dismayed were no signs of infection or anything in my blood count that would be a cause.

Now that we have a background, hematuria is blood in the urine. I have no pain in any manner. I have had kidney stones in the past, and I can tell you right now, there is no stone caught anywhere.

According to the Mayo Clinic (http://www.mayoclinic.com/health/blood-in-urine/DS01013), seeing blood in your urine can cause more than a little anxiety. Yet, blood in urine isn’t always a matter for concern. Strenuous exercise can cause blood in urine, for instance. So can a number of common drugs, including aspirin. But urinary bleeding can also indicate a serious disorder.

Anxiety indeed. Urine RBC/HMF cells do have a normal range of 0-5 HPF. Mine was at 29. I was concerned and called my GP for an immediate verification. The next day it was discovered I did not have the number 29, but it was now doubled. Great graham crackers!

Next stop, Augusta Health Center for the urologist. Again it was verified I had an unusually high amount of red blood cells in my urine.

Now for some pre information. There are two types of blood in urine. Blood that you can see is called gross hematuria. Urinary blood that’s visible only under a microscope is known as microscopic hematuria and is found when your doctor tests your urine. Either way, it’s important to determine the reason for the bleeding.

Treatment depends on the underlying cause. Blood in urine caused by exercise usually goes away on its own within one or two days, but other problems often require medical care.

The visible sign of hematuria is pink, red or cola-colored urine — the result of the presence of red blood cells. It takes very little blood to produce red urine, and the bleeding usually isn’t painful. If you’re also passing blood clots in your urine, that can be painful. A lot of times, though, bloody urine occurs without other signs or symptoms.

In many cases, you can have blood in your urine that’s visible only under a microscope (microscopic hematuria).

When to see a doctor
Although many cases of hematuria aren’t serious, it’s important to see your doctor any time you notice blood in your urine. Keep in mind that some medications, such as the laxative Ex-lax, and certain foods, including beets, rhubarb and berries, can cause your urine to turn red. A change in urine color caused by drugs, food or exercise usually goes away within a few days. However, you can’t automatically attribute red or bloody urine to medications or exercise, so it’s best to see your doctor anytime you see blood in your urine.

In hematuria, your kidneys — or other parts of your urinary tract — allow blood cells to leak into urine. A number of problems can cause this leakage, including:

§ Urinary tract infections. Urinary tract infections are particularly common in women, though men also get them. They may occur when bacteria enter your body through the urethra and begin to multiply in your bladder. The infections sometimes, though not always, develop after sexual activity. Symptoms can include a persistent urge to urinate, pain and burning with urination, and extremely strong-smelling urine. For some people, especially older adults, the only sign of illness may be microscopic blood.

§ Kidney infections. Kidney infections (pyelonephritis) can occur when bacteria enter your kidneys from your bloodstream or move up from your ureters to your kidney(s). Signs and symptoms are often similar to bladder infections, though kidney infections are more likely to cause fever and flank pain.

§ A bladder or kidney stone. The minerals in concentrated urine sometimes precipitate out, forming crystals on the walls of your kidneys or bladder. Over time, the crystals can become small, hard stones. The stones are generally painless, and you probably won’t know you have them unless they cause a blockage or are being passed. Then, there’s usually no mistaking the symptoms — kidney stones, especially, can cause excruciating pain. Bladder or kidney stones can also cause both gross and microscopic bleeding.

§ Enlarged prostate. The prostate gland — located just below the bladder and surrounding the top part of the urethra — often begins growing as men approach middle age. When the gland enlarges, it compresses the urethra, partially blocking urine flow. Signs and symptoms of an enlarged prostate (benign prostatic hyperplasia, or BPH) include difficulty urinating, an urgent or persistent need to urinate, and either gross or microscopic bleeding. Infection of the prostate (prostatitis) can cause the same signs and symptoms.

§ Kidney disease. Microscopic urinary bleeding is a common symptom of glomerulonephritis, which causes inflammation of the kidneys’ filtering system. Glomerulonephritis may be part of a systemic disease, such as diabetes, or it can occur on its own. It can be triggered by viral or strep infections, blood vessel diseases (vasculitis), and immune problems such as IgA nephropathy, which affects the small capillaries that filter blood in the kidneys (glomeruli).

§ Cancer. Visible urinary bleeding may be a sign of advanced kidney, bladder or prostate cancer. Unfortunately, you may not have signs or symptoms in the early stages, when these cancers are more treatable.

§ Inherited disorders. Sickle cell anemia — a chronic shortage of red blood cells — can be the cause of blood in urine, both gross and microscopic hematuria. So can Alport syndrome, which affects the filtering membranes in the glomeruli of the kidneys.

§ Kidney injury. A blow or other injury to your kidneys from an accident or contact sports can cause blood in your urine that you can see.

§ Medications. Common drugs that can cause visible urinary blood include aspirin, penicillin, the blood thinner heparin and the anti-cancer drug cyclophosphamide (Cytoxan).

§ Strenuous exercise. It’s not quite clear why exercise causes gross hematuria. It may be trauma to the bladder, dehydration or the breakdown of red blood cells that occurs with sustained aerobic exercise. Runners are most often affected, although almost any athlete can develop visible urinary bleeding after an intense workout.

That’s enough to take right now, huh? What my point is, follow me through the entire process of discovery. Right now, my symptoms have been weight loss for no reason, tired and lethargic and wacky insulin numbers. I have no pain, nor do I have an out of range blood parameter. I want you to learn from my mistakes or misgivings. It does not hurt when you go to your physician to ask for urine test. It is performed right there in minutes. Having this knowledge, you are armed to do battle and persevere.

Now my next sheet of urology orders is for a CT abdomen/pelvis with and without IV contrast. IVcontrast? That means a needle. No solid foods four hours prior to 3:34 pm. I am likely to starve. I am then slotted for a cystoscope.

Men and boys, hooo boy.

Next article, I shall describe what a CT does, shows and what is seen in me for you readers to know. Including the cystoscope, that I do believe was engineered during the Spanish Inquisition. Until then, ciao.
