Ultrasonic ureteric jet study: A comparison with the voiding cystourethrogram for the detection of vesico-ureteric reflux in children

The ultrasonic ureteric jet study is a non-invasive method of measuring the distance between the midline of the bladder and the ureteric orifice (MOD). Statistical comparison with the results of single cycle voiding cystourethrograms (VCU) indicates that a normal MOD measurement on the ureteric jet study is a good predictor of the absence of vesico-ureteric reflux (VUR). For ureters of children less than 4 years of age, a MOD ≤8mm has a negative predictive value of 83% (95% confidence interval; 74-93%). For ureters of children aged 4-10 years, a MOD ≤9mm has a negative predictive value of 91% (95% confidence interval; 86-97%). The ureteric jet study has the potential to identify children who..
