Introduction:

The symptomatology of urinary tract infection is variable in pediatric ages, therefore, there are typical and atypical clinical pictures due to multiple factors studied and defined but that offer difficulty for diagnostic confirmation.

Objective:

Identify the usefulness of the diagnostic parameters of urinary tract infection.

Methods:

Observational, analytical, case-control study in infants admitted with suspected urinary tract infection at "Octavio de la Concepción y de la Pedraja" University Pediatric Hospital and admitted to the pediatric clinic service. The total sample were infants with suspected urinary tract infection and the sample was 191 patients who met the inclusion criteria. The variables used were age, sex, signs and symptoms, clinical factors, clinical forms, microbiological parameters, clinical parameters according to the presence of Rochester criteria and evaluation scales for bacterial infection and laboratory parameters.

Results:

The most important clinical variables associated with a urinary tract infection were: age less than three months, fever and non-enjoyment of breastfeeding; while laboratory variables were: anemia, leukocytosis, neutrophilia and elevated erythrosedimentation.

Conclusions:

A set of clinical parameters and laboratory studies useful in the medical care of children with urinary tract infection are identified. The form of febrile presentation is the specific characteristic of the disease and hematological and urinary sediment investigations are sources of diagnostic support.
