The role of radiology in urinary tract infection in children
Insights
Routine uroradiography in children diagnosed with urinary tract infections reveals significant abnormalities, especially in those under three years old. Pseudomonas infections are strongly linked to these radiologically detectable abnormalities.
Area of Science:
- Pediatric Radiology
- Infectious Diseases
- Urology
Background:
- Urinary tract infections (UTIs) are common in children, necessitating accurate diagnostic approaches.
- Radiological assessment plays a crucial role in identifying structural abnormalities associated with UTIs.
- Early detection of anomalies can prevent long-term renal complications.
Purpose of the Study:
- To determine the incidence of radiological abnormalities in children referred for UTI diagnosis.
- To evaluate the effectiveness of different uroradiographic techniques based on age.
- To investigate the association between specific pathogens and radiological findings.
Main Methods:
- Retrospective analysis of 758 children undergoing uroradiography for suspected UTI.
- Categorization of patients by age (under 3 years vs. over 3 years).
- Correlation of radiological findings with identified infecting organisms.
Main Results:
- Overall incidence of radiological abnormality was 30%, rising to 40% in children under 3 years.
- Excretory urography was effective for screening children over 3 years.
- Voiding cysto-urethrography was critical for children under 3 years.
- Pseudomonas infections were associated with a significantly higher incidence (70%) of abnormalities compared to other organisms (30%).
Conclusions:
- Routine uroradiographic investigation is recommended for all children diagnosed with UTI.
- Age-specific imaging protocols are essential for optimal detection of urinary tract abnormalities.
- Pseudomonas UTI warrants heightened suspicion for underlying structural anomalies.
Abstract:
Of 758 children examined by uroradiography at the Transvaal Memorial Hospital for Children, 232 (30%) had been referred for the diagnosis of urinary tract infection. The incidence of radiological anomaly or abnormality in these children was an overall 30%; in the first 3 years of life this figure rose to 40%. Radiological investigation of these children should be undertaken routinely. Excretory urography alone is a satisfactory screening procedure in children over the age of 3 years; under this age, formal voiding cysto-urethrography is of immense importance. The incidence of 70% of underlying radiologically detectable abnormalities associated with Pseudomonas infection was statistically significantly higher than the 30% found in association with all other infecting organisms.
