Pediatric Urology - Vesicouretreal reflux

​​​​​​​​​​Vesicouretreal reflux (VUR) occurs when there is a backward flow of urine through the ureters (tubes) from the bladder into the kidneys. 

When this happens, bacteria that is present in the urine reaches the kidneys and may cause an infection or chronic kidney disease. 

Marshfield Clinic has pediatric specialists who are expertly trained in the diagnosis and treatment of issues associated with VUR.


A Marshfield Clinic physician will assess your child's condition and recommend a treatment plan. The most common courses are:

Watchful waiting
In many cases, VUR will actually go away on its own. As your child gets older, the ureters may start to grow normally and the condition will correct itself. Antibiotics are given to prevent infection while the bladder matures.

Deflux injection
Nearly seven out of ten children can have positive results with an endoscopic (instrument with a tiny guided camera) injection in or around the spot where the ureter enters the bladder. The procedure requires no incision and is often successful in repairing the valve and keeping urine from refluxing.

In some cases a surgeon will recommend a procedure to create new ureter valves to prevent the backflow of urine into the kidneys.​
