Abstract

Purpose: Vesicoureteral reflux is the most common urinary tract abnormality in children. Although voiding cystourethrography is the gold standard for diagnosing reflux, this approach is invasive. We evaluated color Doppler ultrasound measurement of ureteral jet angle as a noninvasive screening tool for detecting reflux. Materials and Methods: We retrospectively evaluated 125 children (250 renal units) who presented with urinary tract infections or hydronephrosis. All patients underwent color Doppler ultrasonography and voiding cystourethrography. Ureteral jet angle was measured as angle between the direction of the ureteral jet and interureteral ridge. Results: Reflux was diagnosed in 80 patients (117 renal units). Mean ± SD ureteral jet angle was significantly greater in refluxing units (67.9 ± 18.7 degrees) than in nonrefluxing units (47.8 ± 17.3 degrees, p
