Insights
Pediatric urinary tract infections (UTIs) linked to urological malformations present with atypical microbes and higher recurrence rates. Early diagnosis with imaging and urine culture is crucial for effective management of childhood UTIs.
Area of Science:
- Pediatric Urology
- Infectious Diseases
- Medical Microbiology
Background:
- Urinary tract infections (UTIs) are common in children and are closely associated with urological malformations.
- The impact of urological malformations on the clinical presentation of pediatric UTIs requires further elucidation.
Purpose of the Study:
- To characterize the clinical features and microbial etiology of UTIs in children.
- To investigate the influence of urological malformations on UTI presentation and outcomes in pediatric patients.
Main Methods:
- Retrospective review of 741 pediatric UTI cases from 2015-2020.
- Propensity score matching (PSM) to compare patients with and without urological malformations.
Main Results:
- Escherichia coli was the predominant pathogen (40.5%).
- Urological malformations were present in 16.5% of patients.
- Patients with malformations had a higher proportion of atypical UTI microorganisms (P=0.048), longer IV antibiotic treatment, increased costs, and higher recurrence rates (23.8% vs. 10.7%, P<0.001).
Conclusions:
- Children with urological malformations are more prone to developing UTIs caused by atypical microorganisms.
- Recommended diagnostic approaches include imaging and urine culture for pediatric UTIs, especially in cases with suspected malformations.
Background:
Urinary tract infection (UTI) is a common occurrence in children. UTI and urological malformations are intimately linked. However, whether urinary tract malformations affect the clinical features of pediatric UTI remains unclear. The purpose of this study was to characterize the clinical features and microbial etiology of UTI in children.
Methods:
We retrospectively reviewed the records of 741 patients with UTI treated at the Chongqing Medical University Affiliated Children's Hospital between 2015 and 2020. Patients with and without urological malformations were compared using propensity score matching (PSM).
Results:
Escherichia coli was the most common causative microorganism of UTI, accounting for 40.5% of infections. One hundred twenty-two patients (16.5%) had urological malformations. PSM identified 122 matched pairs of patients with or without urological malformations. The proportion of patients with UTI caused by atypical microorganisms was significantly higher in patients with urological malformations (P = 0.048). Children with urological malformations showed longer duration of intravenous antibiotic treatment (P = 0.010), higher cost of treatment (P < 0.001), and higher prevalence of recurrence (23.8 vs. 10.7%, P < 0.001), compared with the normal group.
Conclusion:
Children with urological malformations are more likely to develop UTI with atypical microorganisms. Appropriate imaging examination and urine culture are strongly recommended for the diagnosis and management of pediatric UTI.
