  Hematuria (Blood in the Urine) What is hematuria? Hematuria is the presence of red blood cells (RBCs) in the urine. In microscopic hematuria, the urine appears normal to the naked eye, but examination with a microscope shows a high number of RBCs. Gross hematuria can be seen with the naked eye — the urine is red or the color of cola. [ Top ]  What causes hematuria? Several conditions can cause hematuria, most of them not serious. For example, exercise may cause hematuria that goes away in 24 hours. Many people have hematuria without any other related problems. Often no specific cause can be found. But because hematuria may be the result of a tumor or other serious problem, a doctor should be consulted. [ Top ]  How is hematuria diagnosed? To find the cause of hematuria, or to rule out certain causes, the doctor may order a series of tests, including urinalysis, blood tests, kidney imaging studies, and cystoscopic examination.    Urinalysis is the examination of urine for various cells and chemicals. In addition to finding RBCs, the doctor may find white blood cells that signal a urinary tract infection or casts, which are groups of cells molded together in the shape of the kidneys' tiny filtering tubes, that signal kidney disease. Excessive protein in the urine also signals kidney disease.    Blood tests may reveal kidney disease if the blood contains high levels of wastes that the kidneys are supposed to remove.    Kidney imaging studies include ultrasound, computerized tomography (CT) scan, or intravenous pyelogram (IVP). An IVP is an x ray of the urinary tract. Imaging studies may reveal a tumor, a kidney or bladder stone, an enlarged prostate, or other blockage to the normal flow of urine.     A cystoscope can be used to take pictures of the inside of the bladder. It has a tiny camera at the end of a thin tube, which is inserted through the urethra. A cystoscope may provide a better view of a tumor or bladder stone than can be seen in an IVP. [ Top ]   How is hematuria treated? Treatment for hematuria depends on the cause. If no serious condition is causing the hematuria, no treatment is necessary. [ Top ]  ,,,,,,,,,,,,,,,,,,,,,,,, What is blood in urine (hematuria)? Hematuria, or blood in the urine, can be either gross (visible) or microscopic (as defined by more than three to five red blood cells per high power field when viewed under magnification). Gross hematuria can vary widely in appearance, from light pink to deep red with clots. Despite the quantity of blood in the urine being different, the types of conditions that can cause the problem are the same, and the workup or evaluation that is needed is identical. People with gross hematuria usually present to their doctor with this as a primary complaint. Microscopic hematuria, on the other hand, is most commonly detected as part of a periodic checkup by a primary-care physician. What are the causes of blood in urine? 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 srcinating 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 fully evaluated by a physician, even if it resolves spontaneously. Infection of the urine, stemming either from the kidneys or bladder, is a common cause of microscopic hematuria. 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 (or kidney) disease, as well as 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.   Font Size  A    A    A   Share This Previous  1  2 3     4  Next   Blood In Urine Index  Glossary  Blood In Urine (cont.)
