Vesicoureteral reflux (VUR) is the backward flow of urine. The urine flows from the bladder back into the kidneys.
Urine normally flows out 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. This connection 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 back-up can also put extra pressure on the kidney. This can cause kidney damage.
This is a potentially serious condition. It requires care from a doctor. Early treatment and prevention of infections can lead to better outcomes. If you suspect your child has this condition, call the doctor right away.
