• Blood in the urine can sometimes be visible only with a microscope.

• Evaluating blood in urine requires consideration of the entire urinary tract.

• Tests used for the diagnosis of blood in urine may include a CT scan, cystoscopy, ultrasound, IVP, MRI, urine culture, and urine cytology.

• Management of blood in the urine depends upon the underlying cause.

Hematuria, or blood in the urine, can be either gross (visible) or microscopic (blood cells only visible through a microscope). Gross hematuria can vary widely in appearance, from light pink to deep red with clots. Although the amount of blood in the urine may be different, the types of conditions that can cause the problem are the same and require the same kind of workup or evaluation.

People with gross hematuria will visit their doctor with this as a primary complaint. People who have microscopic hematuria, on the other hand, will be unaware of a problem, and their condition will most commonly be detected as part of a periodic checkup by a primary-care physician.

What Causes Hematuria

The causes of gross and microscopic hematuria are similar and may result from bleeding anywhere along the urinary tract. One cannot readily distinguish between blood originating in the kidneys, ureters (the tubes that transport urine from the kidneys to the bladder), bladder, or urethra. Any degree of blood in the urine should be thoroughly evaluated by a physician, even if it resolves spontaneously.

Infection of the urine, (often called a urinary tract infection or UTI) stemming from the kidneys or bladder, is a common cause of microscopic hematuria. Urine is naturally sterile and should not contain bacteria. Kidney and bladder stones can cause irritation and abrasion of the urinary tract, leading to microscopic or gross hematuria. Trauma affecting any of the components of the urinary tract or the prostate can lead to bloody urine.

Hematuria can also be associated with renal (kidney) disease and hematologic disorders involving the body’s clotting system. Medications that increase the risk of bleeding, such as aspirin, warfarin (Coumadin), or clopidogrel (Plavix), may also lead to bloody urine. Lastly, cancer anywhere along the urinary tract can present with hematuria.

Hematuria Diagnosis

The evaluation for blood in urine consists of taking a history, performing a physical examination, evaluating the urine with a chemical test strip and under a microscope, and obtaining a urine culture to identify any bacteria present. Lower urinary tract symptoms, such as urgency (feeling a strong need to urinate) and frequency (needing to urinate frequently), and burning or pain when urinating, the presence of fever or chills, are suggestive of infection. Recent trauma, even if believed by the patient to have been inconsequential, should be considered a potential cause. Abdominal or flank pain, especially if radiating to the inguinal or the genital area, may suggest ureteral or kidney stones. All recent medications, including vitamins or herbal supplements, should be reviewed with the health-care professional. However, it is essential to note that even if the patient has been taking a medication associated with bleeding, a full workup (as listed below) should still be undertaken.

The physical exam will focus on possible sources of hematuria. Bruising over the back or abdomen may indicate trauma. A digital rectal exam should be performed, especially in males, as findings consistent with prostatitis (for example, tenderness on palpation of the prostate) or an enlarged prostate suggestive of benign prostatic hyperplasia (BPH), may be useful in making a diagnosis. The finding of a nodule or an area of induration (hardening) of the prostate may be indicative of cancer. A repeat urinalysis, as well as a urine culture, should be obtained. Blood tests are also necessary, as they will help assess renal function and identify any clotting abnormalities.

In addition to the basic history and physical exam, there are three additional components for any workup of hematuria: imaging, urine cytology, and cystoscopy.

The CT scan is an imaging evaluation of the urinary tract. Before the procedure, the patient drinks an oral contrast agent, and a dye is injected intravenously. The patient then goes through the CT scan machine, and images are taken of the abdomen and pelvis. Another test that can be performed, the intravenous pyelogram (IVP), is also a type of X-ray evaluation of the urinary tract. In this procedure, a dye is injected into the veins, and the urinary tract filters this. A series of X-rays are then taken over 30 minutes to look for abnormalities.

The CT scan is more commonly performed than the IVP to evaluate the urinary tract and should be considered the test of choice. Both of these studies are especially useful for evaluating the kidneys and ureters, but not the bladder, prostate, or urethra. Therefore, a second examination called a cystoscopy is necessary. This is a simple 10-minute procedure using a thin, flexible cystoscope (or fiberoptic camera) inserted via the urethra into the bladder to visualize any lesions or sources of bleeding directly. This is usually done with local anesthetic jelly injected into the urethra.

Finally, urine cytology involves giving a urine sample to be analyzed by a pathologist for cancerous or abnormal-appearing cells. Looking for a professional urologist Brooklyn? Doral Health and Wellness — Men’s Health Center is the most reputed company that leading the pride.

Hematuria Treatments

Treatments for hematuria vary widely and depend on the reason for the bleeding. It is important to note that quite often no cause is found for the hematuria. However, this should not be a source of significant concern since an appropriate workup effectively rules out the most severe hematuria causes (for example, cancer).

In cases where a workup is negative, and the cause of the hematuria remains unknown, observation with repeat urinalyses is a reasonable option. A blood test to check kidney function and a blood-pressure check should be done as well. Caucasian men over 50 should discuss with their doctor an annual prostate-specific antigen (PSA) blood test, which is used to screen for prostate cancer. Prostate screening in African Americans traditionally begins at age 45, and in all races, a history of prostate cancer in close family members may indicate an earlier start of the screening.

Further discussion of the treatment for hematuria would depend upon the workup’s results and the exact cause for the hematuria. The urologist who performs this examination is responsible for recommending any further treatment or workup necessary.
