What is hidden blood in the urine of a 10-year-old child

Urinary occult blood in 10-year-old children may be caused by intense exercise, urinary tract infections, glomerulonephritis, urinary system stones, or hereditary kidney disease. Specific examinations should be conducted to determine the cause.

1. Intense exercise:

High intensity exercise may lead to temporary urinary occult blood, and accelerated renal blood flow during exercise may cause red blood cells to pass through the glomerular filtration membrane. Usually, there are no other discomfort symptoms. After resting for 48 hours, rechecking the urine routine can often restore normal levels. It is recommended to avoid repeated intense exercise in the short term and observe changes in urine color. 2. Urinary tract infection: Cystitis or urethritis caused by bacterial infection is a common cause of urinary occult blood in children, often accompanied by symptoms of frequent urination and urgency. Escherichia coli is the most common pathogenic bacterium, and elevated white blood cells can be seen in urine routine. Diagnosis requires urine culture, and treatment should be based on drug sensitivity results to select sensitive antibiotics such as cefuroxime, amoxicillin, and clavulanate potassium.

3. Glomerulonephritis: Children with acute streptococcal infection and glomerulonephritis may present with hematuria and proteinuria, and often have a history of upper respiratory tract infection before onset. It may be related to the deposition of immune complexes that damage the glomerular basement membrane, typically manifested as eyelid edema in the morning. Anti chain O antibodies and complement C3 need to be tested, and renal biopsy may be performed if necessary.

4. Urinary calculi:

The incidence rate of urinary calculi in children is low but should not be ignored. When bladder stones or ureteral stones move, they may scratch the mucosa and cause hematuria. Ultrasound examination can detect a high echo mass accompanied by symptoms of lumbar and abdominal colic. Smaller stones can be expelled by drinking plenty of water, while larger stones require extracorporeal shock wave lithotripsy treatment.

5. Hereditary nephropathy:

Genetic diseases such as Alport syndrome can present as persistent microscopic hematuria, often accompanied by sensorineural hearing loss or eye abnormalities. There is often a similar medical history in the family, and genetic testing can provide a clear diagnosis. Regular monitoring of renal function is necessary, and renal replacement therapy may be necessary in the late stages.

found that children with occult blood in urine should maintain sufficient water intake, with a daily water intake of 1-1.5 liters to promote urination. Avoid a high salt and high protein diet that increases the burden on the kidneys and limit the intake of processed foods. Observe the frequency of urination and changes in urine color, and record the time of occurrence of abnormal symptoms. Re check urine routine within 2 weeks, if it continues to be positive, complete urinary system ultrasound, renal function and other examinations are required. Avoid using hemostatic drugs without authorization, and all treatments should be carried out under the guidance of a pediatrician. Pay attention to the cleanliness and hygiene of the perineum, and choose breathable cotton underwear to reduce local friction. School aged children should avoid holding urine for long periods of time and maintain regular urination habits during breaks.
