The URAMIX Easy-Jet Irrigator (UEJI) is an easy to use irrigation system for endoscopic automatic stone irrigation, which takes advantage of current equipment and provides both gravity and pump assisted irrigation, controlled by a foot pedal and precluding the requirement of an assistant. The device is compact, attaches to an IV pole and uses regular irrigation tubing. Irrigation fluid can flow freely through gravity or can be amplified by the pump for pulsatile flow to remove stone fragments, improve visualization and dislodge impacted stones.
