Insights
Urinary tract infections (UTI) in children can lead to kidney damage. This study analyzed imaging results for 100 children with UTI, finding that abnormal scans were common, highlighting the importance of appropriate imaging for management.
Area of Science:
- Pediatric Nephrology
- Diagnostic Imaging
- Infectious Diseases
Background:
- Urinary tract infections (UTI) in children can result in significant renal scarring, potentially leading to hypertension and renal impairment.
- Early and accurate diagnosis of UTI complications is crucial for effective management and prevention of long-term sequelae.
- The role of various imaging modalities in evaluating pediatric UTI and their correlation with patient demographics and infection characteristics requires further elucidation.
Purpose of the Study:
- To describe the utilization frequencies of different imaging studies employed in the investigation of pediatric UTI.
- To analyze the outcomes of imaging modalities in children diagnosed with UTI at King Fahad Hospital (KFH) from 2003 to 2008.
- To explore the relationship between imaging findings, patient age, sex, and the type of UTI.
Main Methods:
- A descriptive study was conducted on 100 children diagnosed with UTI via urinary cultures at KFH.
- Patients were categorized into three age groups: >1 month to 2 years, >2 to 5 years, and >5 to 12 years.
- Imaging modalities included renal ultrasonography (US), 99mTc-dimercaptosuccinic acid (DMSA) scan, and micturating cystourethrogram (MCUG), with DMSA and MCUG primarily performed for abnormal US findings or recurrent UTIs.
Main Results:
- 97% underwent US, 77% had DMSA scans, and 60% had MCUG. Females constituted 90% of the study population.
- E-coli was the predominant pathogen (84%). 60% experienced recurrent UTI, and 45% had pyelonephritis.
- Abnormal findings were noted in 48.4% of renal US, 61% of DMSA scans, and 26.6% of MCUGs.
Conclusions:
- UTI in children can lead to substantial morbidity if not managed promptly and effectively.
- Imaging studies play a vital role in identifying pediatric patients requiring advanced medical intervention for UTI.
- The judicious use of imaging studies, based on clinical indications, is essential for optimal patient care and resource allocation.
Abstract:
Urinary tract infections (UTI) can cause significant renal scarring, which can be complicated by hypertension and renal impairment. This study describes the outcome of different imaging modalities in children with UTI and its relation to age, sex and type of UTI. Our objective was to describe the frequencies of different imaging studies, which were used to investigate children with UTI at King Fahad Hospital (KFH) between the years 2003 and 2008. This is a descriptive study of all children presenting with UTI at KFH from 2003 to 2008. The study population, 100 children , were divided into 3 age groups; first group (> 1 month to 2 years); second group (> 2 to 5 years) , third group (> 5 to 12 years). All enrolled children were confirmed to have had UTI via urinary cultures. Ninety seven (97%) patients underwent renal ultrasonography (US), 77 (77%) had a 99mTc-dimercaptosuccinic acid (DMSA) scan within 2 months of presentation, and 60 (60%) patients underwent micturating cystourethrogram (MCUG), mainly those with an abnormal DMSA scan. A total of 100 patients screened, 10 (10%) were males and 90 (90%) were females, first age group constituted 10%, second age group was 25% , third age groups was 65%. E-coli was isolated in 84% of patients, 60% had recurrent UTI, 45% had pyelonephritis, 48.4% had abnormal renal US, 61% had an abnormal DMSA scan, and 26.6% had abnormal MCUG. UTI can cause significant morbidity in children if not managed properly. Imaging studies are useful in identifying children who require advanced medical intervention; however, such studies should be performed only when indicated.
