Vesicoureteral reflux (VUR) is a medical condition where urine flows backward from the bladder into the ureters and sometimes up to the kidneys. This abnormal flow can lead to urinary tract infections (UTIs) and kidney damage if not treated. VUR is often diagnosed in children and can be caused by a malfunctioning valve at the junction of the bladder and ureters. Treatment options for VUR may include antibiotics to prevent infections, regular monitoring, or surgical procedures to correct the reflux. Early detection and management are crucial to prevent complications and ensure healthy urinary function.
