[The frequency of urinary tract infections in hospitalized infants]
Insights
Urinary tract infections (UTIs) affected 12% of hospitalized infants between 1979-1983. Early diagnosis is crucial due to high rates of kidney infection (cytopyelonephritis) and vesicoureteric reflux in infants.
Area of Science:
- Pediatrics
- Infectious Diseases
- Nephrology
Context:
- Retrospective analysis of hospitalized infants from 1979-1983.
- Focus on the incidence and characteristics of urinary tract infections (UTIs).
Purpose:
- To determine the frequency of UTIs in hospitalized infants.
- To highlight the significance of early UTI diagnosis in infancy.
Summary:
- The study found a 12% average frequency of bacterial UTIs in hospitalized infants over a five-year period.
- Cytopyelonephritis (kidney infection) was diagnosed in 70.7% of cases.
- Vesicoureteric reflux was present in 36.5% of children with UTIs.
- Girls were more prevalent among infants with UTIs, including neonates.
- UTI symptoms in infants are often non-specific.
Impact:
- Emphasizes the need for early and accurate diagnosis of UTIs in infants, especially those with fever.
- Highlights the high prevalence of cytopyelonephritis and vesicoureteric reflux, underscoring the importance of timely intervention.
Abstract:
The authors present the frequency of urinary tract infections in hospitalised infants. A retrospective study of infants hospitalized during a five year period, from 1979-1983 was made. The average frequency for the mentioned period was 12%, all of which were bacterial infections. In 70.7% of patients we diagnosed cytopyelonephritis. Girls prevailed among the patients with urinary tract infections, even in the neonatal period. Vesicoureteric reflux was confirmed in 36.5% children. The results of this study show that the symptoms of urinary tract infections in infancy are not specific. As the frequency of cytopyelonephritis and vesicoureteric reflux was high it emphasizes the significance of early diagnosis. In every febrile child, diagnosis of urinary tract infections should be suspected.
