DOPPLER ULTRASOUND: EVALUATION OF URETERIC JETS AS A NOVEL MEASURE IN DIAGNOSIS OF URETERIC OBSTRUCTION

Abstract

Color Doppler U/S of the ureteral jets is an available tool in • urinary colics because it yieldin real time more precise of functional information than radiograph and B mode U/S and also demonstrate the grade of urinary obstruction . The aim of this study is to evaluate patients with renal colic by ureteric jets in Doppler U/S. This study include 58 ureteric units, all patients in this study are admitted at emergency department of Benha University Hospitals with renal colic. All patients are evaluated by: • Urine analysis. • Serum creatinine. • Plain radiography. • Conventional US • Intravenous urography if indicated. Then patients with evidence of ureteric obstruction by these methods of investigation are involved in the study and evaluated by : • Color Doppler U/S (detection of ureteric jets and tabulated in the following parameters:• • • Frequency of jets (mean 4 jet/5 min). • Inter-jet interval (up to 150 sec).
