Symptoms of urinary tract infection in children, parents should pay attention to these knowledge

Almost all people will suffer from urinary tract infections, including infants and young children. The symptoms of urinary tract infections in infants and young children are also relatively obvious, but some symptoms are the same as those of other diseases, so some parents will make wrong judgments. This also reminds everyone to make judgments based on a comprehensive analysis of various symptoms.

1. Neonatal period

The main symptoms are systemic symptoms, such as fever, refusal to feed, pallor, vomiting, diarrhea, abdominal distension, slow weight gain, sluggishness, convulsions, jaundice, etc., while urinary system symptoms are rare.

2. Infancy

The main symptoms are still systemic symptoms, such as fever, loss of appetite, vomiting, abdominal pain, recurrent diarrhea, etc. Urinary system symptoms become more obvious with age. Some children cry when urinating, have interrupted urine stream, frequent urination and enuresis.

3. Childhood

Most patients have typical bladder irritation symptoms such as frequent urination, urgency, and pain when urinating, and sometimes pain in the kidney area and lower abdomen. A few patients have transient hematuria, and most systemic symptoms are not prominent. Some children have fever and chills.

4. Chronic infection

The course of the disease is usually more than 6 months. It is less common in children, and the symptoms vary in severity, from no obvious symptoms to renal failure. Patients with a long course of illness may suffer from anemia, malnutrition, developmental delay, etc. When renal function is impaired, there are hypertension, polyuria, and renal tubular dysfunction.

Causes of Urinary Tract Infection in Children:

1. Ascending infection

Infants and young children often use diapers or wear open-crotch pants, and their urethral openings are often contaminated by feces and other unclean substances. In addition, their local defense capabilities are poor, which can easily cause ascending infection. Girls have shorter urethras and are more susceptible to infection. In addition, in infancy, the ureters running inside the bladder wall are not fully developed, are short or abnormal, and fail to close completely during urination, causing reflux. Bacteria ascend with the refluxed urine and cause infection.

2. Descending infection

Congenital malformations and urinary tract obstruction, such as hydronephrosis, ureteral stenosis, and polycystic kidney disease, can all lead to secondary infection due to poor drainage. Obstruction caused by stones, tumors, etc. can also cause bacterial backflow and lead to urinary tract infection.

3. Bloody infection

Urinary tract infection can be part of systemic sepsis in infants and young children and a concomitant symptom in children with chronic bacteremia.
