Radiological findings in newborn infants with urinary infection
Insights
Urinary tract infections (UTIs) are uncommon in newborns, affecting 0.5% of infants. However, a high rate of radiological abnormalities (55%) in infected infants suggests the need for imaging in diagnosed cases.
Area of Science:
- Neonatal Medicine
- Pediatric Urology
- Infectious Diseases
Background:
- Urinary tract infections (UTIs) are a significant concern in neonates.
- Early diagnosis and management are crucial for preventing long-term complications.
Purpose of the Study:
- To determine the incidence of UTIs in live-born infants.
- To investigate the association between UTIs and radiological abnormalities in this population.
- To inform clinical guidelines regarding diagnostic imaging for neonatal UTIs.
Main Methods:
- A prospective study involving selective suprapubic urine aspiration (SUPA) in 12,942 consecutive live-born infants.
- Urine samples were analyzed for infection.
- Infants with confirmed UTIs underwent radiological investigations.
Main Results:
- A UTI was diagnosed in 64 infants (0.5% incidence).
- Males constituted a majority (84%) of infected infants.
- Radiological abnormalities were identified in 35 (55%) of infants with UTIs.
Conclusions:
- Newborn infants with confirmed UTIs exhibit a high prevalence of associated radiological abnormalities.
- Radiological investigations should be considered in the management of neonates diagnosed with urinary tract infections.
- Prompt diagnosis and imaging may alter clinical management and improve outcomes.
Abstract:
Selective suprapubic urine aspiration was performed in 905 of 12 942 consecutive live-born infants and showed the presence of infection in 64 (0-5%). A majority (84%) of the infected infants were males. Radiological abnormalities were detected in 35 (55%). Because of this high incidence of abnormalities, which when diagnosed might alter management, it is suggested that radiological investigations be performed in newborn infants with proven urinary infection.
