ceVUS is a radiation-free and sensitive examination to detect vesicoureteral reflux and image the urethra in children using ultrasound (US) and intravesical administration of an ultrasound contrast agent (UCA). Due to the growing interest to perform ceVUS in children, a urinary bladder phantom was developed to teach the technical aspects of the ceVUS examination. Here we describe the preparation and utility of this reusable phantom as a tool to simulate the UCA administration, distribution and the effect of different US parameters on the UCA appearance in the bladder.

Contrast enhanced voiding urosonography (CEVUS) uses intravesically administered microbubble contrast to detect vesicoureteral reflux (VUR) and urethral anomalies with ultrasound. Multiple studies have suggested CEVUS can replace voiding cystourethrogram (VCUG) as a radiation free alternative. Analysis of ureterovesical junction (UVJ) and ureters on VCUG documenting UVJ position, ureteral duplication, periureteral diverticula and ureteroceles is important as anatomic variations may affect management and surgical approach. Our purpose was to assess UVJ region visualization in children with VUR detected on CEVUS. Read More

Fluoroscopic voiding cystourethrography (VCUG) and radionuclide cystography (RNC) are conventional techniques used for the diagnosis of vesicoureteral reflux (VUR) in children. Contrast-enhanced voiding urosonography (ceVUS) is a radiation-free alternative to the traditional VCUG. ceVUS has gained acceptance in Europe, but has not yet been widely adopted in the USA.

The purpose of this educational review is to describe our initial experience with ceVUS using the second generation US contrast agent Optison™, with a focus on optimization of examination technique, utility in the depiction of a variety of pathological entities, and a discussion of potential pitfalls.
