The relationship between dysfunctional voiding and congenital vesicoureteral reflux

Area of Science:

• Pediatric Urology
• Nephrology
• Developmental Biology

Background:

• Congenital vesicoureteral reflux (VUR) in children may be associated with voiding dysfunction.
• Aberrant lower urinary tract function and structural deficiencies of the ureterovesical junction are implicated in VUR etiology.
• Voiding dysfunction can be congenital or acquired during toilet training.

Purpose of the Study:

• To explore the etiological role of voiding dysfunction in congenital vesicoureteral reflux.
• To highlight the association between lower urinary tract dysfunction and VUR in infants and children.
• To emphasize the clinical significance of recognizing and managing voiding dysfunction in VUR patients.

Main Methods:

• Review of existing evidence linking voiding dysfunction and VUR.
• Analysis of the developmental and acquired aspects of lower urinary tract dysfunction.
• Discussion of clinical outcomes associated with undiagnosed/untreated voiding dysfunction.

Main Results:

• Voiding dysfunction is increasingly recognized as a factor in congenital VUR.
• Both structural and functional abnormalities of the lower urinary tract contribute to VUR.
• Undiagnosed voiding dysfunction correlates with higher rates of breakthrough infections, renal scarring, and surgical failure.

Conclusions:

• Voiding dysfunction plays a significant etiological role in congenital VUR.
• Recognition and management of lower urinary tract dysfunction are vital for improving outcomes in children with VUR.
• Further research is needed to clarify the roles of urodynamics and anticholinergic therapy.
