what does vu reflux mean
en espaÃ±olReflujo vesicoureteral (VUR) We've all heard of acid reflux â when stomach acids move up into the esophagus and cause a burning sensation â but there can be other types of reflux in the body. When urine (pee) refluxes from the bladder to the kidneys, it's called vesicoureteral reflux (VUR). Vesicoureteral (ves-ih-koe-yoo-REE-ter-ul) reflux happens when urine abnormally flows backward from the bladder into the ureters, thin tubes that connect the kidneys to the bladder.
