Introduction:

Urinary tract infection is considered, in the developed world, the most common serious bacterial disease during infancy and early childhood. It is the most frequent reason for pediatric consultation in relation to the urinary system.

Objective:

To characterize the clinical and microbiological aspects of patients with urinary tract infection admitted to the Pediatric service.

Methods:

Descriptive, cross-sectional study of 85 admitted patients with a diagnosis of urinary tract infection, from September 2017 to September 2019. The variables used were: age, sex, risk factors, clinical manifestations and isolated germ. Data were obtained from medical records. Percentage summaries were performed for qualitative variables and mean and standard deviation for quantitative variables.

Results:

Urinary infection predominated in patients under a year (58.8%) of the female sex (83.5%). The risk factors identified were the use of disposable buttocks (40%) and not exclusive breastfeeding (36.5%). Fever was the predominant sign (56.5%) and Escherichia coli the most isolated germ in urine cultures (76.4%).

Conclusions:

Urinary tract infection occurs more frequently in children under one year of age, female. The incorrect use of disposable calves and early weaning predominate as risk factors. The most frequent germ was Escherichia coli.
