Insights
Vesicoureteric reflux (VUR) is often seen in girls post-urinary tract infection. However, neonates with prenatal sonogram abnormalities show a male predominance, with 80% being boys.
Area of Science:
- Pediatric Urology
- Neonatal Medicine
- Renal Medicine
Background:
- Vesicoureteric reflux (VUR) is a common condition in children.
- Traditionally recognized in girls following urinary tract infections (UTIs).
- Emerging data highlights VUR detection in neonates via prenatal sonography.
Purpose of the Study:
- To analyze the demographic and etiological differences in VUR presentation.
- To investigate the sex distribution of VUR in neonates detected prenatally.
- To differentiate congenital versus acquired VUR in pediatric populations.
Main Methods:
- Retrospective analysis of pediatric VUR cases.
- Comparison of VUR incidence based on age at diagnosis and sex.
- Correlation of prenatal sonogram findings with VUR diagnosis.
Main Results:
- VUR is frequently diagnosed in girls after UTIs.
- Neonatal VUR, identified through prenatal ultrasounds, exhibits a strong male predominance (80% boys).
- Congenital VUR is more prevalent in boys, while acquired VUR is more common in girls with voiding dysfunction.
Conclusions:
- Vesicoureteric reflux presentation varies significantly by age and sex.
- Prenatal sonographic detection of VUR in neonates indicates a male predilection.
- Understanding these differences is crucial for accurate diagnosis and management of pediatric VUR.
Abstract:
Vesicoureteric reflux is most commonly recognized in girls after urinary tract infection. Increasing recognition of vesicoureteric reflux in neonates, detected after an abnormal prenatal sonogram, shows a marked male predominance: 80% boys. Vesicoureteric reflux in children may be both a congenital abnormality, more common in boys, and an acquired abnormality, more common in girls with voiding dysfunction.
