Insights
Applying NICE guidelines for pediatric urinary tract infection (UTI) imaging may miss significant vesicoureteral reflux (VUR) cases in children under 3. This study suggests these guidelines are not suitable for current clinical practice.
Area of Science:
- Pediatric Nephrology
- Urology
- Diagnostic Imaging
Background:
- Urinary tract infections (UTIs) in young children require careful diagnostic evaluation.
- National Institute of Health and Clinical Excellence (NICE) guidelines offer recommendations for imaging studies in children with UTI.
- The impact of applying these NICE guidelines in clinical practice requires assessment.
Purpose of the Study:
- To evaluate the consequences of implementing NICE guidelines for imaging in children under 3 with UTI.
- To determine potential alterations in diagnosis and treatment due to NICE guideline application.
- To assess the diagnostic yield and clinical utility of current imaging protocols versus NICE recommendations.
Main Methods:
- Retrospective cohort study of 672 pediatric patients diagnosed with UTI.
- Evaluation of indications and outcomes for renal ultrasonography, voiding cystourethrography (VCUG), and dimercaptosuccinic acid scintigraphy.
- Analysis of UTI recurrence, antimicrobial prophylaxis (AMP), and surgical interventions.
Main Results:
- Application of NICE guidelines would have missed 47% of patients with vesicoureteral reflux (VUR).
- Specifically, 31% of dilating VUR cases and 43% of patients undergoing antireflux procedures would have been undetected.
- Conversely, 74% of voiding cystourethrography (VCUG) procedures in patients without VUR could have been avoided.
Conclusions:
- The current NICE guidelines for imaging studies in children under 3 with UTI are not recommended for clinical practice.
- The guidelines may lead to underdiagnosis of significant conditions like VUR.
- A revised approach to imaging guidelines is necessary to ensure appropriate diagnosis and management of pediatric UTIs.
Introduction:
We assessed the possible consequences of applying the National Institute of Health and Clinical Excellence (NICE) guidelines for imaging studies of children younger than 3 years with urinary tract infection (UTI) to clinical practice, in terms of altered diagnoses and treatment.
Material And Methods:
In a retrospective cohort of 672 patients with UTI, we evaluated indications for and results of renal and bladder ultrasonography, voiding cystourethrography (VCUG), dimercaptosuccinic acid scintigraphy, UTI recurrence, antimicrobial prophylaxis (AMP), antireflux procedures, and other urological procedures.
Results:
There were a total 125 patients with vesicoureteral reflux (VUR), of whom 59 patients (47%) would have been missed, had the NICE guidelines being applied. These included 20 of the 64 patients (31%) with dilating VUR and 13 of the 30 patients (43%) who underwent antireflux procedures. A VCUG would have been avoided in 184 patients (74%) with no VUR in VCUG.
Conclusion:
Based on the results in this cohort of 672 patients, we cannot recommend the use of the NICE guidelines for imaging studies in children younger than 3 years with UTI.
