Vesicoureteral reflux (VUR) happens when urine flows from your bladder back into the kidney.
Urine normally flows from the kidneys, passes through tubes called ureters, then flows into the bladder. Each ureter connects to the bladder in a way that prevents urine from flowing back up the ureter, 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 and cause kidney damage.
