Vesicoureteral reflux (VUR) is a condition in which urine flows backwards from the bladder to one or both ureters and sometimes to the kidneys.[1] While no symptoms may occur, it may result in urinary tract infections (UTI).[1] Complications may include kidney problems and it may be associated with bedwetting.[1]
Risk factors include a family history.[1] The underlying mechanism often involves the valve between the ureter and bladder not closing properly.[1] Other causes may include bladder outlet obstruction or a neurogenic bladder.[1] Diagnosis may involved an ultrasound or voiding cystourethrogram.[1]
As the condition may resolve as a child grows, close follow-up and rapid treatment of UTIs maybe recommended.[1][2] Long-term antibiotics may also be used to prevent infection.[2] Surgery or injections of bulking agents may be used in severe disease or for certain causes.[1][2]
VUR is estimated to affect about 1% of people.[2] It is more common in children who have a UTI and fever, affecting about a third of this group.[1] Young children are most commonly affected.[1] Girls are more commonly affected than boys.[1] The condition has been described since the 1st century.[3] Successful surgical repair was first carried out in 1952.[4]
