What causes hematuria in children?

Urination is a very important physiological behavior of the human body. It can excrete excess water and useless metabolic products from the body. Some children will experience some adverse conditions when urinating, and hematuria is a relatively common condition. In the face of this situation, it is necessary to understand the cause and then take effective measures to treat it. Here we will introduce what is going on with hematuria in children.

There are many possibilities for children's hematuria, and relevant examinations are needed.

Guidance:

1. First check the relevant information. Some children are caused by infection, some are caused by other diseases, and there is no obvious relationship between them and bedwetting.

2. If all the examinations are good except for blood in the urine, then you should consider the possibility of simple hematuria. There is no specific treatment method. The main thing is to take some kidney-protecting medicines. Some children will get better in a few months or half a year, while some will remain like this forever. Regular kidney function checks will be sufficient.

3. If you want to get a complete and thorough understanding, you need to do a renal puncture, but this is not necessary at the moment. After all, it is an invasive minor operation. If there is no way after half a year or even a year, you can consider a renal puncture if you want to understand the situation.

4. You don’t need to pay special attention to your daily life, as long as you don’t overwork yourself, and there is nothing to avoid in terms of food.

Once a child has hematuria, parents will become very anxious. In fact, there are many reasons for hematuria in children, which represent different physical health conditions of the children. Parents can observe carefully and not panic. First of all, red urine does not necessarily mean hematuria. The normal color of children's urine is light yellow. If the urine is red, you should be alert to the occurrence of hematuria, but not all red urine means hematuria. If too much urate is excreted in the urine, the urine will appear pink. The urate in the urine of newborns can make the diaper red. When children consume large amounts of food dyes (such as aniline), antipyrine, or honey, their urine may appear red. Certain drugs such as rhubarb, phenolphthalein, rifampicin, tetracycline, and purine drugs may also cause the urine to appear red. The above red urine is not hematuria. Secondly, you don’t need to worry about temporary hematuria, such as hematuria after exercise. Some children find hematuria after strenuous activities such as running or playing ball, but there is no obvious discomfort in the body and no other associated symptoms. This is hematuria after exercise, and the cause is kidney damage caused by strenuous exercise. There is no special treatment for exercise-induced hematuria. You can take some hemostatic drugs and let the child rest until the hematuria disappears. In the future, when exercising, you should start with a small amount and gradually increase the amount to improve the child's body and kidneys' tolerance to exercise.

Third, the causes of hematuria in children vary with age. For example, neonatal hematuria can be seen in spontaneous hemorrhage of the newborn, severe hypoxia and asphyxia. In addition to congenital urinary tract malformations, polycystic kidney disease, and hydronephrosis, hematuria in infancy is also commonly seen in urinary tract infections. Hematuria in preschool and school age is most commonly caused by acute glomerulonephritis, followed by chronic glomerulonephritis, Henoch-Schonlein purpura nephritis, urinary tract infection, etc. Fourth, look at the causes of hematuria in children from the characteristics of hematuria 1. The color of hematuria. Bright red is mostly lower urinary tract bleeding, and dark red is mostly upper urinary tract bleeding. 2. The shape of the blood clot. If the urine contains large flat blood clots, it indicates that the hematuria comes from the bladder, thin and long blood clots come from the ureter, and triangular blood clots come from the kidneys. Urethral bleeding, blood dripping from the urethral opening, indicates urethral injury. Judging from the urination situation, a thin line of urine indicates urinary tract obstruction, and urination accompanied by symptoms such as frequent urination, pain, and urgency indicates urinary tract infection or bladder stones. Fifth, what are the specific causes of hematuria in children: 1. Glomerular hematuria in children: ① Nephrotic syndrome: hematuria is accompanied by edema, large amounts of proteinuria, and blood tests show high cholesterol and hypoproteinemia. ② Glomerulonephritis: Children with this disease often have a recent history of skin pustules, boils, pharyngitis, tonsillitis, etc., accompanied by hematuria
