Mathias, MD09/09/2019058cba73-f76f-4dcf-b6c5-734c445d0c86https://kidshealth.org/ws/RadyChildrens/en/parents/hematuria.html/<h3>What Is Hematuria?</h3> <p>When blood gets into urine (pee), it's called hematuria (hee-ma-TUR-ee-uh). It's pretty common and usually not serious. There are two types of hematuria:</p> <ul class="kh_longline_list"> <li><strong>Microscopic hematuria</strong> is when blood in the urine can be seen only with a microscope. Often, this goes away without causing any problems. In fact, people might never know they have it unless they get a <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/labtest7.html/">urine test</a>.</li> <li><strong>Gross hematuria</strong> is when you can see the blood in the pee even without a microscope. This is because there is enough blood in the pee to turn it red or tea-colored.</li> </ul> <h3>How Does Blood Get Into the Urine?</h3> <p>Blood leaks into the <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/kidneys-urinary.html/">urinary tract</a>. This can happen anywhere in the urinary tract such as:</p> <ul> <li>in the kidneys, which remove waste and water from the blood to make pee</li> <li>in the ureters, which are tubes that carry pee from the kidneys to the bladder</li> <li>in the bladder, which stores pee</li> <li>in the urethra, where pee leaves the body</li> </ul> <h3>What Causes Hematuria?</h3> <p>Kids can get hematuria for many reasons. Common causes include:</p> <ul> <li>bladder or kidney infections</li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/kidney-stones.html/">kidney stones</a></li> <li>high levels of calcium and other minerals in the urine</li> <li>a problem with the urinary tract</li> <li>injury to the kidneys or urinary tract</li> <li>taking some types of medicines, like some over-the-counter pain medicines</li> <li>strenuous exercise (many athletes, especially distance runners, get hematuria from time to time)</li> </ul> <p>In rare cases, hematuria can be a sign of kidney cancer or bladder cancer, a blood disease, or a blood clot. If something like that is going on, hematuria usually will be one of many symptoms.</p> <p><img class="center_this" title="The urinary system is shown" src="https://kidshealth.org/EN/images/illustrations/P-uniaryTractA-415x233-enIL.png" alt="The urinary system is shown" /></p> <p>Sometimes what looks like hematuria might be something else. Things like food dye, some foods (like beets or blackberries), a girl's monthly <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/talk-about-menstruation.html/">period</a> (menstruation), and some prescription medicines can make pee look red.</p> <h3>What Are the Signs &amp; Symptoms of Hematuria?</h3> <p>Microscopic hematuria has no visible signs. Doctors will only know someone has it if a urine test finds it.</p> <p>Gross hematuria is seen because it changes the color of urine, which can happen with only a little bit of blood. Often, red or tea-colored urine is the only symptom.</p> <p>In some cases, hematuria can be one of many symptoms of another condition. For example, if a bladder infection is causing the hematuria, other symptoms might include <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/fever.html/">fever</a>, pain while peeing, and lower belly pain.</p> <h3>How Is Hematuria Diagnosed?</h3> <p>The doctor will do an exam and ask about symptoms, recent activities, and the family medical history. Your child will give a urine sample (pee in a cup) for testing.</p> <p>Sometimes, more tests are done, such as a:</p> <ul> <li>blood test</li> <li>urine culture</li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/renal-ultrasound.html/">kidney ultrasound</a></li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/mri.html/">MRI</a></li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/cat-scan-abdomen.html/">CT scan</a></li> </ul> <p>Kids with hematuria that doesn't go away, who have <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/test-protein.html/">protein in the urine</a>, and/or <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/hypertension.html/">high blood pressure</a> should see a nephrologist (a doctor who specializes in kidney care).</p> <h3>How Is Hematuria Treated?</h3> <p>Most of the time, hematuria doesn't need any treatment. If it only happens once, it's nothing to worry about.</p> <p>If another condition is causing the hematuria, doctors will treat that condition. For instance, hematuria from a <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/urinary.html/">urinary tract infection (UTI)</a> is treated with antibiotics.</p> <p>If your child was treated for hematuria, the doctor probably will do follow-up tests to make sure there's no more blood in the urine.</p>Sangre en la orina (hematuria)La presencia de sangre en la orina, también conocida como hematuria, es bastante común y, en la mayoría de los casos, no es grave.https://kidshealth.org/ws/RadyChildrens/es/parents/hematuria-esp.html/bff6c08b-d2f0-4b65-a0b2-7dd495b8e55a

Kidney DiseaseSometimes, the kidneys can't do their job properly. In teens, kidney disease is usually due to infections, structural issues, glomerulonephritis, or nephrotic syndrome. https://kidshealth.org/ws/RadyChildrens/en/teens/kidney.html/4f21e885-14a9-4b12-a514-66998f93043c
