Joanna Tzovara MD, PRESENTER: Nothing to Disclose

Abstract: HTML Purpose: To increase the ability of contrast enhanced voiding urosonography (VUS) in depicting vesicoureteral reflux (VUR) by performing two cycles. Methods and Materials: One hundred twelve consecutive children (mean age 2.9 years) with 224 kidney ureter units (KUU) underwent two cycles of contrast enhanced VUS followed immediately by standard fluoroscopic voiding cystourethrography (VCUG). Results: VUR was detected in 57 KUU from 44 (39%) children at first cycle of VUS. From the remaining 68 non refluxing children 8 (12%) demonstrated VUR at the second cycle (p=0.045). Most cases of missed reflux at first cycle was grade II (75%). However, in 2 KUU (17%) missed reflux was grade III. Comparing both cycles of VUS with VCUG concordant findings regarding the presence and the grade of reflux were found in 82% of KUU. Conclusion: The second cycle of contrast enhanced VUS disclosed significantly more cases of VUR and increased the ability of the method to disclose reflux.
