Occult blood in children's urine?

If a child has occult blood in his urine and has no other uncomfortable symptoms, generally speaking, it is impossible to confirm the severity of the disease. At this time, if kidney disease can be ruled out, pay close attention to the baby. If the baby has no uncomfortable symptoms, do not do anything for now. Let the baby drink more water and pay attention to frequent urination. Urinalysis needs to be repeated.

Normally there are no red blood cells in the urine of a person, or there are a small number of red blood cells after exercise. But if the number of red blood cells in the urine exceeds the normal amount, it is what we call hematuria. Method for determining hematuria: Take 10 ml of clean fresh midstream urine and centrifuge it at 1500 rpm for 5 minutes, then take the urine sediment for microscopic examination. If there are ≥ 3 red blood cells per high-power microscopic field in centrifuged urine, or more than 1 red blood cell count in non-centrifuged urine or 1 hour urine, or more than 500,000 red blood cell count in 12-hour urine sediment, all indicating an abnormal increase in red blood cells in the urine, it is called hematuria. In mild cases, only an increase in red blood cells is found under a microscope, which is called microscopic hematuria; in severe cases, the appearance is like meat washing water or contains blood clots, which is called gross hematuria. Usually, when there is 1 mL of blood per liter of urine, it can be seen with the naked eye, and the urine appears red or like meat washing water.

There are many causes of occult blood in urine, about 98% of which are caused by urinary system diseases themselves, and only 2% are caused by systemic or adjacent organ lesions. We check the red blood cells in the urine. When they are of different sizes, have various morphological changes, and have hemoglobin loss, that is, when deformed red blood cells are predominant (polymorphic), it is glomerular hematuria. If the morphology of the urine red blood cells is basically normal and uniform (homogeneous type), it is non-glomerular hematuria. Examination of the morphology of red blood cells in urine can help us preliminarily determine the site of hematuria.

Parents should pay attention to occult blood in children's urine. Because occult blood in urine is often one of the first symptoms of many diseases, if it is not taken seriously, it may easily lead to misdiagnosis or delayed treatment, and drug abuse should be avoided. Some diseases, such as certain nephritis and IgA nephropathy, may progress or worsen, and long-term follow-up observation should be emphasized. In addition to paying attention to occult blood in the urine, attention should also be paid to whether there is urine protein and its degree, and whether there is high blood pressure, because these two symptoms are sometimes more significant to the prognosis of the disease than occult blood in the urine.

Of course, parents also need to avoid excessive tension and fear. Sometimes urine microscopy is negative, but occult blood is positive (+~++), and the diagnosis of urine occult blood mainly depends on microscopy. Some parents worry that long-term occult blood in urine will lead to anemia, but in fact occult blood in urine itself does not cause a lot of blood loss; some parents worry that occult blood in urine will lead to renal failure, but in fact only a very small number of diseases with occult blood in urine as the main symptom will progress to renal failure.

In short, if a child has occult blood in the urine, parents must pay attention to it and go to the hospital for consultation and examination as soon as possible to determine the cause of hematuria. Avoid blindly abusing Chinese and Western medicines, and be careful of their toxic side effects on the kidneys.
