Vesicoureteral reflux (VUR) is the backward flow of urine. The urine flows from the bladder back into the kidney.
Urine normally flows from the kidneys. It passes through tubes called ureters. It then flows into the bladder. Each ureter connects to the bladder in a way that prevents urine from flowing back up the ureter. It is similar to a one-way valve. When this does not work properly, or if the ureters do not extend far enough into the bladder, urine may flow back up to the kidney. If the urine contains bacteria, the kidney may become infected. The backup can also put extra pressure on the kidney. This can cause kidney damage.
This is a potentially serious condition that requires care from your doctor. The sooner VUR is treated, the better the outcome. If you suspect you or your child has this condition, contact your doctor immediately.

In rare cases, high blood pressure may be an indication of kidney damage.
The goal for treatment of VUR is to prevent any permanent kidney damage. Treatment options include the following:
Most cases of VUR in children clear up on their own. The problems may clear as the ureters develop. Observation may include:
Regular urine cultures
Antibiotics—children at risk of infections or who have had many infections are often placed on low dose, daily antibiotics
Annual check-ups on kidney functions
Children are advised to stay well hydrated. They should also frequently empty their bladders.
Endoscopic injection into the ureter
This procedure is a minimally invasive surgery. It is done to correct the reflux. A chemical is injected where the ureter inserts into the bladder. This will prevent urine from going back up the ureter. This procedure is done through a small tube called a

VUR can not be prevented. However, further complications can be avoided:
Seek prompt treatment for bladder or kidney infections.
This is particularly true if you have a neurogenic bladder.
