Vesicoureteral reflux (VUR) is the most common urologic diagnosis in neonates estimated at 1% of newborns, and 30-45% of the children who present with urinary tract infection (1). Optional treatments of children with VUR include conservative therapy with or without prophylactic antibiotics, and endoscopic, laparoscopic, or open surgery. In an endoscopic technique, the injecting needle is inserted through the working channel of the cystoscope. The procedure is relatively short and is performed as out-patient surgery. In 2000, Dextranomer/Hyaluronic acid (DefluxR) was approved by the FDA, and subsequently has become the treatment of choice in VUR grades 2-4. In 2004, the hydrodistention-implantation technique (HIT) was introduced by Kirsch. HIT involves the use of a pressurized stream of fluid directed into the ureter to aid visualization, and injection into the submucosa within the ureteric tunnel to improve coaptation of the ureter (3). One of the disadvantages attributed to Deflux is the loss of 20% of the injected material over time (a result of absorption of the hyaluronic acid), which may explain the lower success rate of the endoscopic treatment of VUR compared with open surgery. In 2005, Polyacrylate Polyalcohol (VantrisR), a non- absorbable chemical preparation was introduced for endoscopic treatment of VUR, aiming to improve on the results of Deflux by preventing volume loss. Preliminary results of a three year follow-up using Vantris have shown high a level of reflux resolution(4). The aim of the current study is to compare the rate of resolution of the VUR using Deflux versus Vantris in bilateral VUR
