Clinical analysis of 468 children with urinary tract infection

  Objective  To analyze the clinical features, pathogens distribution and imaging examination conditions in children with urinary tract infection (UTI).

  Methods  A total of 468 UTI patients were selected, and were divided into infant group (1 month to 1 year old), toddler group (above 1 year to 3 years old) and children group (above 3 years old). Clinical data of the three groups were analyzed.

  Results  Urinary tract infection in children was more common in infants. In the infant group, the rate of children with fever as the first symptom was 52.15%, which was significantly higher than that in the infant group (17.27%) and the children group (5.23%) (P < 0.05). The rate of urinary tract irritation in children group was 63.37%, which was significantly higher than that in the infant group (8.60%) and the toddler group (41.82%) (P < 0.05). The rate of abnormal development of urinary tract in the infant group was 32.80%, which showed statistically significant difference compared with that in the toddler group (21.82%) and the children group (17.44%) (P < 0.05). In addition, 105(22.43%) were detected pathogens in 468 patients, including 71 cases with Gram-negative bacteria (67.62%), with Escherichia coli ranking first, and 31 with Gram-positive bacteria (29.52%), with Enterococcus faecium accounting for the most.

  Conclusion  Infant urinary tract infection is more common in boys, and the clinical symptoms are lack of specificity. Most of the clinical manifestations are fever, and local symptoms are not obvious, so routine urine detection should be paid attention. With the increase of age, the rate of urinary tract infection in girls is gradually increasing, and the rate of children with urinary tract irritationas the main clinical manifestation is also gradually increasing. Escherichia coli is still a common pathogen in children with UTI. The main pathogenic bacteria of urinary tract infection were Gram-negative bacilli, Escherichia coli accounted for the highest proportion, and the detection rate of Enterococcus faecium among Gram-positive bacteria is also relatively high.
