Urinary tract infections in children.

M R Weir, R M Lampe

    American Family Physician
    |January 1, 1984
    PubMed
    Summary

    Absolute colony counts are insufficient for diagnosing pediatric urinary tract infections (UTIs). Empiric treatment is viable with positive nitrite tests or occasional organisms, and radiologic evaluation is recommended for enuretic patients with UTIs.

    Area of Science:

    • Pediatric Nephrology
    • Infectious Diseases
    • Clinical Microbiology

    Background:

    • Urinary tract infections (UTIs) are common in children.
    • Accurate diagnosis of pediatric UTIs is crucial for appropriate treatment and preventing complications.
    • Current diagnostic criteria, including absolute colony counts, may require refinement.

    Purpose of the Study:

    • To evaluate the diagnostic and therapeutic utility of absolute colony counts in pediatric UTIs.
    • To assess the effectiveness of empirical treatment strategies based on urinalysis findings.
    • To determine the role of localizing studies and radiologic evaluation in managing pediatric UTIs.

    Main Methods:

    • A five-year retrospective review of pediatric patients diagnosed with UTIs.
    • Analysis of urine culture results, including absolute colony counts.
    • Correlation of urinalysis findings (nitrite positivity, organism presence) with UTI diagnosis.
    • Review of diagnostic and therapeutic outcomes of localizing studies.
    • Assessment of radiologic evaluation in patients with enuresis and UTIs.

    Main Results:

    • Absolute colony counts alone were not satisfactory for diagnosing UTIs.
    • Empirical treatment prior to culture results was effective when urine was nitrite-positive or showed occasional organisms.
    • Localizing studies provided no significant diagnostic or therapeutic benefit.
    • Radiologic evaluation identified anatomic abnormalities in patients with enuresis and infection.

    Conclusions:

    • Relying solely on absolute colony counts for pediatric UTI diagnosis is inadequate.
    • Urinalysis parameters like nitrite positivity and organism presence can guide empirical treatment.
    • Localizing studies are not beneficial in this patient cohort.
    • Anatomic evaluation is warranted for children with enuresis and UTIs to rule out underlying abnormalities.
