Pronounced: VEH-sih-co-ya-REET-uh-rul REE-flux
Vesicoureteral reflux (VUR) is the backward flow of urine. The urine flows from the bladder back into the kidney.
Urine normally flows from the kidneys. It passes through tubes called ureters. It then flows into the bladder. Each ureter connects to the bladder in a way that prevents urine from flowing back up the ureter. The connection is 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, causing damage or kidney failure.

The goal for treatment of VUR is to prevent any permanent kidney damage. Treatment options include the following:
This procedure is a minimally invasive surgery. It is done to correct the reflux. A gel is injected where the ureter inserts into the bladder. This can prevent urine from going back up the ureter. This procedure is done through a small tube called a cystoscope.
This surgery repositions the ureters in the bladder. It can be done in two ways. One way requires making an incision above the pubic bone and repositioning the ureters in the bladder. It can also be done laparoscopically by inserting cameras through small incisions in the abdomen and/or bladder to perform the surgery.
