Abstract
The relationship between vesicoureteral reflux and bladder dysfunction is inseparable and has long been emphasized. However, the primary concern of all physicians treating patients with vesicoureteral reflux is the prevention of renal scarring and eventual deterioration of renal function. Bladder dysfunction, urinary tract infection and vesicoureteral reflux are the three important factors which are closely related to each other and contribute to the formation of renal scar. Especially, there is ongoing discussion regarding the role of bladder dysfunction in the prognosis of both medically and surgically treated vesicoureteral reflux. The effect of bladder dysfunction on VUR is mostly via inadequate sphincter relaxation during infancy which is closer to immature bladder dyscoordination rather than true dysfunction. But after toilet training, functional obstruction caused by voluntary sphincter constriction during voiding is responsible through elevation in bladder pressure, thus distorting the architecture of bladder and ureterovesical junction. Reports suggest that voiding phase abnormalities in lower urinary tract dysfunction contributes to lower spontaneous resolution rate of VUR. However, filling phase abnormalities such as involuntary detrusor contraction can also cause VUR even in the absence of dysfunctional voiding. With regards to the effect of bladder dysfunction on treatment, meta-analysis reveals that the cure rate of VUR following endoscopic treatment is less in children with bladder bowel dysfunction but there is no difference for open surgery.
