- predominantly febrile temperature (38 ° C and above);
- pain in the lumbar region, abdomen;
- symptoms of intoxication (pallor, lethargy, decreased appetite, headache, vomiting);
- leukocyturia;
- bacteriuria;
- proteinuria (insignificant or moderate, as a rule, not exceeding 1 g / day);
- violation of the process of urine concentration, especially in the acute period;
- neutrophilic leukocytosis with a leftward shift;

Symptoms of urinary tract infections depending on age
The urinary system of newborns and infants (the first 2 years of life) is most vulnerable to infection. This is due to anatomical and physiological features (intracine location of pelvis, convoluted and hypotonic ureters, immaturity of their neuromuscular apparatus) and physiological insufficiency of local immunity. It is known that the synthesis of IgG in children is fully formed to 2-3 years, and IgA - to 5-7 years of life.
In the clinical picture of urinary tract infection in newborns and young children, nonspecific symptoms of intoxication predominate: fever, pallor or marbling of the skin, lethargy, decreased appetite, vomiting and regurgitation, insufficient weight gain or loss, diarrhea.
The only symptom of a urinary tract infection in young children (especially the newborn and the first year of life) may be fever (fever).
Equivalent dysuria in children of the first year of life may be anxiety or crying before, during and after urination, redness of the face, "groaning", tension of the suprapubic region, urination in small portions, weakness and intermittence of the urine stream.
In older children, along with intoxication, local symptoms are revealed: abdominal and lumbar pain, soreness in the rib and vertebral corner with effleurage and palpation, tenderness over the bosom and dysuria.
