Therapy for vesicoureteral reflux: antibiotic prophylaxis, urotherapy, open surgery, endoscopic injection, or...

Vesicoureteral reflux (VUR) refers to the retrograde flow of urine from the bladder into the ureter and renal pelvis. It generally results from congenital maldevelopment of the ureterovesical junction, although VUR may develop in individuals with abnormally high detrusor pressure. VUR increases a child's susceptibility to pyelonephritis and renal scarring. Treatment goals include the prevention of pyelonephritis, reflux nephropathy, and other complications of reflux. Treatment alternatives include antibiotic prophylaxis, urotherapy (correction of voiding dysfunction), and surgical correction (open, injection therapy, or laparoscopic). Recent studies have challenged the presumed benefit of prophylaxis in children with VUR, while long-term retrospective studies have documented a high rate of hypertension in adults with reflux nephropathy. In addition, the risk of persistent VUR in adulthood is unresolved. These reports have stimulated a reevaluation of the role of various treatment options in children with VUR.
