Purpose: To compare the sensitivity of voiding US (VUS) with echo enhancement with that of VUS with air and voiding cystourethrography (VCUG) for diagnosis of vesicoureteral reflux (VUR).
Methods and Materials: 98 children referred for investigation of VUR VUS with echo enhancement, followed by VUS with air as well as VCUG at one examinational sequence. After transurethral catheterization of the bladder with an infant feeding tube the bladder was filled either with echo enhancement (Levovist), air or x-ray contrast medium (Imeron). The sequence of methods was changed from patient to patient.
Results: In 61 of a total of 195 examined kidney-ureter units a VUR was identified. 22 VUR were diagnosed with all three methods alike. VUS with echo enhancement as well as with air showed five VUR, VUS with echo enhancement and VCUG four VUR and VUS with air and VCUG two VUR. Exclusively by VUS with echo enhancement five, by VUS with air six and by VCUG seventeen VUR were detected. Altogether by VUS with echo enhancement 36 VUR, by VUS with air 35 VUR and by VCUG 45 VUR were identified.
Conclusion: All three methods were sensitive in detection of VUR. Due to the examination of more micturations the number of recognized VUR increased. At primary examination a combination of VCUG and VUS should be used. In VUS air is to be preferred as contrast.
