What is bladder ureteral reflux?

Vesicoureteral reflux (VUR) is a condition in which urine flows from the bladder to the ureter and renal pelvis during urination. VUR

VUR occurs in women, children, and those with a history of repeated urinary tract infections. It can cause symptoms such as frequent micturition, urinary pain, urgency, and fever
