The sight of blood in the urine is enough to make anyone panic. Having blood in the urine may or may not be cause for concern but if you notice this, it does need to be checked out with your physician to rule out any serious conditions.
Medically, blood in the urine is known as hematuria. There are two forms of hematuria:
· Gross Hematuria – This is when you can see blood in the urine. The urine may look pink, red, or cola-colored due to the presence of red blood cells (RBCs). Most of the time, other than the change in appearance in urine, most people do not have other symptoms.
· Microscopic Hematuria – This is when you cannot see blood in the urine but it can be seen when the urine is examined with a microscope. Most people with microscopic hematuria have no symptoms.
Causes of blood in the urine
When a person has hematuria, the kidneys or other parts of the urinary tract allow blood cells to leak into the urine. Anyone, including children, can be at risk for blood in the urine. There can be many reasons for this and it does not automatically mean a serious condition. Some common causes of hematuria include:
· Vigorous or strenuous exercise
· Sexual activity
· Bacterial or viral infection
· Family history of kidney disease
More serious problems that could be causing blood in your urine might be:
· Irritation or swelling in the kidney, prostate in men, or another part of the urinary tract
· Blood clots
· Enlarged prostate
Hematuria is diagnosed with a urine sample called a urinalysis. The urine sample is collected in a special container at a doctor’s office and usually tested in a lab for analysis. The lab technician places a strip of chemically treated paper called a dipstick in the urine. If RBCs are present, patches on the dipstick change color. When RBCs are noted, then the urine is further examined under a microscope to make the diagnosis of hematuria.
Depending on the circumstances, the doctor may order further testing such as a urinalysis, blood test, biopsy, cystoscopy, or a kidney imaging test.
Hematuria is treated by treating its underlying cause. If the reason for hematuria is not serious, no treatment may be necessary. If it is caused by a urinary tract infection, it will be treated with antibiotics. A urinalysis should be repeated within 6 weeks after antibiotic treatment ends to be sure the infection is gone.
