What are the symptoms of urinary tract infection in children?

Since children have poorer physical constitutions and relatively weaker immune systems, they do not have much resistance to some diseases, especially urinary tract infections, which have more symptoms and a longer course of illness. The following are some symptoms of urinary tract infections in children.

Symptoms of urinary tract infection in children

1. Acute urinary tract infection. It refers to patients with a disease course of less than 6 months. Symptoms vary depending on age and where the infection affects the affected area. Older children are similar to adults. The younger the child, the more obvious the systemic symptoms are, and local urination irritation symptoms are often mild or easily ignored.

1. In the neonatal period, it is mostly caused by bloodstream infection. The symptoms vary in severity, with systemic symptoms being the main ones, such as fever, poor feeding, pallor, vomiting, diarrhea, abdominal distension and other non-specific manifestations. Most children may experience growth stagnation and slow weight gain. Some children may have convulsions, lethargy, and sometimes jaundice. However, the symptoms of local urination are generally not obvious, so we must be vigilant about this disease. For unexplained fever, routine urine examination and urine and blood culture should be performed as soon as possible to confirm the diagnosis.

2. In infancy and childhood, systemic symptoms are still the main ones, such as fever, mild cough, and repeated diarrhea. Urinary symptoms such as frequent urination, urgency, and pain become more obvious with age. If your child cries during urination, urinates frequently, or has persistent diaper rash, you should consider this disease. Jaundice may occasionally occur.

3. In childhood, lower urinary tract infection usually presents only with urinary tract irritation symptoms such as frequent urination, urgency, and pain when urinating. Sometimes there may be terminal hematuria and enuresis, but systemic symptoms are usually not obvious. However, systemic symptoms of upper urinary tract infection are often more obvious, manifested as fever, chills, general malaise, and may be accompanied by low back pain and percussion pain in the kidney area. It may also be accompanied by urinary irritation symptoms. Some patients may have hematuria, but proteinuria and edema are usually not obvious. It generally does not affect renal function. If the treatment is not thorough or the disease recurs repeatedly or there are other factors such as urinary tract obstruction and deformity, it may become chronic.

2. Chronic urinary tract infection. Refers to patients with a disease course of more than 6 months and a protracted illness. Symptoms range from no obvious symptoms to renal failure (with impaired concentrating function appearing first). Repeated attacks may manifest as intermittent fever, back pain, fatigue, weight loss, progressive anemia, etc. Local lower urinary tract irritation symptoms may be absent or intermittent. Pyuria and cyturinia may or may not be obvious. The children often have concurrent urinary reflux or congenital urinary tract structural abnormalities. Renal scarring can be seen by B-ultrasound examination or intravenous pyelography. Early correction can reduce kidney damage.
