Abstract: Objective　To investigate the prevalence, clinical characteristics, auxiliary examination, treatment, and efficacy of urinary tract infection in children. Method　The prevalence, clinical characteristics, auxiliary examination, treatment, and efficacy of pediatric urinary tract infection in Binzhou Medical University Hospital from January to December 2021 were retrospectively analyzed. Results　A total of 38 children were included, including 18 males and 20 females; the average age was 3.7 years old; the disease could occur all year round. Clinical characteristics: most of the children had urinary tract irritation, fever, and hematuria, and a few had nausea and vomiting, abdominal pain, and diarrhea. There were 4 cases (10.5%) complicated with respiratory tract infection. Auxiliary examination: 27 cases (71.1%) had elevated white blood cell count in blood routine, and 18 cases (47.4%) had elevated inflammatory indicators of procalcitonin and C-reactive protein. Routine urine examination showed that 34 cases (89.5%) had white blood cell count >5/HPF at high magnification, 24 cases (63.2%) had red blood cell count >3/HPF, and 25 cases (65.8%) had protein +. The positive rate of urine culture was 68.4% (26/38). The positive rate of double kidney, ureter, and bladder color Doppler ultrasound was 42.1% (16/38). Treatment and efficacy: most of the children had a good prognosis after symptomatic supportive treatment such as anti-infection and alkaline urine. Conclusions　Most pediatric urinary tract infections have age characteristics, and most of the symptoms are atypical. Escherichia coli infection accounts for the vast majority, which needs to be combined with urine sediment analysis, urine bacteriological examination, and imaging diagnosis. After formal anti-infection treatment, the vast majority of children can be cured.
