Insights
Voiding cystography is crucial for diagnosing vesicoureteral reflux (VUR) in children with febrile urinary tract infections or urinary tract malformations. However, its use should be limited in children with lower urinary tract dysfunction.
Area of Science:
- Pediatric Urology
- Diagnostic Imaging
Background:
- Vesicoureteral reflux (VUR) is a common condition in children.
- Voiding cystography (VCUG) is a key diagnostic tool for VUR.
- Understanding the diagnostic yield of VCUG based on clinical indications is important for optimizing its use.
Purpose of the Study:
- To analyze the prognosis of VUR based on different indications for VCUG.
- To evaluate the prevalence and degree of VUR in children undergoing VCUG for specific reasons.
Main Methods:
- Retrospective analysis of 4302 children over a 12-year period.
- Children were categorized by VCUG indication: febrile UTI, ultrasonography-detected urinary tract malformations, or lower urinary tract dysfunction.
- Prevalence and degree of VUR were compared across these groups.
Main Results:
- VUR was diagnosed in 21.32% of children overall.
- Reflux prevalence was similar in children with febrile UTI (23.63%) and urinary tract malformations (23.34%).
- Children with lower urinary tract dysfunction showed significantly lower VUR prevalence (14.65%) and degree (p < 0.01).
Conclusions:
- VCUG is highly valuable for detecting VUR in children with febrile UTIs or urinary tract malformations.
- The diagnostic utility of VCUG is lower in children with lower urinary tract dysfunction, suggesting limited indications for this group.
Abstract:
In this study, we report the experience of our center with the prognosis of vesicoureteral reflux, depending on the indications for voiding cystography, during a 12-year period. Retrospective analysis included 4302 children who were analyzed according to the indication for voiding cystography: (1) a febrile urinary tract infection, (2) urinary tract malformations on ultrasonography and (3) lower urinary tract dysfunction. Vesicoureteral reflux was found in 917 patients (21.32%; 24.1% of girls and 17.9% of boys). In group (1), reflux was found in 437/1849 cases (23.63%), group (2) in 324/1388 cases (23.34%) and group (3) in 156/1065 cases (14.65%). A significantly lower prevalence of reflux and its lower degree was found in children from group (3) when compared to other groups (p < 0.01). VURs were confirmed in over 20% of children with urinary tract malformations on ultrasonography or after a febrile urinary tract infection, suggesting the need for voiding cystography in these children. Indications for this examination in children with lower urinary tract dysfunction should be limited.
