Vesicoureteral reflux is a condition where the pressure in the urinary outflow tract increases and urine gets pushed back up into the ureters or kidneys. There are two types of vesicoureteral reflux: primary and secondary.
Primary vesicoureteral reflux is the most common type and happens when a child is born with a defect at the ureterovesical junction, which acts as a valve preventing urine from pushing back from the bladder into the ureter. Secondary vesicoureteral reflux is caused by an acquired condition or disease that causes a blockage in the urinary tract.
The disease often leads to urinary tract infections that can cause renal inflammation and scarring. Treatment options depend on the severity of the condition and may include antibiotics to prevent infections and surgery to correct the reflux.
