title: Absence of vesico-ureteral reflux in children with ureteral jets.
abstract: The jet phenomenon is a normal finding in excretory urography. The presence of such a jet is a good sign that vesico-ureteral reflux is not present. Of 19 ureters with a jet sign, only one had minimal transient ureteral reflux, while in 39 ureters without a jet sign 15 had reflux.
