The one-film urogram in urinary tract infection in children
Abstract:
The sensitivity and specificity of the 5 min postinjection radiograph during urography were studied in 131 children. The 5 min film was overall accurate in 83.2%, with a 56% sensitivity and 91.3% specificity in patients with urinary tract infection (n = 62). In cases in which the 5 min film was not diagnostic, it nevertheless raised enough suspicions to dictate additional films. It is suggested that in urinary tract infection, errors will not be made if the single 5 min postinjection film is reviewed and additional films are obtained only if parts of the urinary tract are incompletely visualized or appear questionable. Further study is necessary to explore the merits of a similar approach for pediatric urography unrelated to urinary tract infection.
Insights
The 5-minute radiograph during urography is accurate for diagnosing urinary tract infections in children. Reviewing this single film and obtaining additional images only when necessary can prevent diagnostic errors.
Area of Science:
- Pediatric Radiology
- Diagnostic Imaging
Background:
- Urography is a common imaging technique in pediatric diagnostics.
- Early radiographic assessments aim to improve diagnostic efficiency.
Purpose of the Study:
- To evaluate the diagnostic accuracy of a single 5-minute postinjection radiograph in pediatric urography.
- To determine the sensitivity and specificity of this early film in identifying urinary tract infections (UTIs).
Main Methods:
- Retrospective analysis of 131 pediatric urography cases.
- Assessment of the accuracy of the 5-minute postinjection radiograph, particularly in children with confirmed UTIs.
Main Results:
- The 5-minute radiograph demonstrated overall accuracy of 83.2% in the studied cohort.
- In children with UTIs (n=62), sensitivity was 56% and specificity was 91.3% for the 5-minute film.
- Non-diagnostic 5-minute films often prompted further imaging, aiding diagnosis.
Conclusions:
- A single 5-minute postinjection radiograph in pediatric urography can be a reliable tool for UTI diagnosis when interpreted with caution.
- Implementing a strategy of reviewing the 5-minute film and obtaining additional images only when visualization is incomplete or questionable may prevent errors.
- Further research is needed to assess this approach for non-UTI pediatric urography.
