| Abstract: | A new method of detecting vesicoureteric reflux (VUR) is presented, utilizing ultrasound as the imaging modality. During the filling phase of a gas cystogram and during micturition, gas bubbles can be seen in the renal pelvis in cases of reflux. In 107 pediatric patients, sonographic reflux studies were performed and compared with radiographic voiding cystourethrograms. The accuracy of the sonographic reflux study was 93.4%, the sensitivity of grade III– IV was 100%, and the specificity was 95.6%. Hence sonographic reflux studies with air have been incorporated into our routine. Since that time, the number of voiding cystourethrograms has decreased by over 80%.Correspondence to: G. Alzen |
