“…91 However, no significant differences in the VUR detection rate between two different heights of 50 cm or 100 cm were reported. 95 VUR onset at <35% predicted bladder capacity was associated with a significantly increased risk of breakthrough febrile UTI. Bladder volume at onset of VUR should be recorded during VCUG, because it predicts the risk of pyelonephritis and resolution.…”

Pediatric voiding cystourethrography: An essential examination for urologists but a terrible experience for children

et al. 2018

Voiding cystourethrography is the most important fluoroscopic examination in pediatric urology for the investigation of lower urogenital tract diseases, such as vesicoureteral reflux or urethral stricture. However, this invasive procedure imposes a significant burden on children and their parents, and recently there has been a paradigm shift in the diagnosis and treatment of vesicoureteral reflux. In the 2011 revision, the American Academy of Pediatrics guidelines on urinary tract infection recommended abandoning routine voiding cystourethrography after the first febrile urinary tract infection. In 2014, the randomized intervention for children with vesicoureteral reflux study recommended discontinuation of routine continuous antibiotic prophylaxis for vesicoureteral reflux. The time is now ripe to radically reconsider indications for voiding cystourethrography and the procedure itself.

“…The contrast material can be introduced into the bladder by using the force of gravity or by using a pneumatic sphygmomanometer. In our center, we use a sphygmomanometer to apply a pressure of 70 mm Hg to the bag; this pressure is equivalent to a 100-cm column of water and represents a high-perfusion study (23)(24)(25) (Fig 1). This pressure does not need to be constant throughout the study; rather, it depends on the patient's abdominal pressure, which varies with the degree of relaxation.The bladder is progressively and homogeneously filled to capacity; however, if a small amount of urine remains in the initial filling phase, it can result in a contrast material-urine level that will disappear when the bladder is completely full (Fig 2), which is when the posterior vesical wall can be correctly depicted.…”

Contrast-enhanced Voiding Urosonography for Vesicoureteral Reflux Diagnosis in Children

et al. 2017

Contrast-enhanced voiding urosonography (ceVUS) is a dynamic imaging technique that makes it possible to study the structure of the urinary tract after the administration of intravesical contrast material. Initially, ceVUS was indicated mainly to study vesicoureteral reflux (VUR); however, since the ability of ceVUS to depict the structure of the urethra was demonstrated in both sexes, ceVUS is now indicated for examination of the entire urinary tract. The main benefit of ceVUS is that it does not use ionizing radiation. In recent years, fundamental changes have occurred in the understanding of VUR. The lessening effect of VUR and the low rate of occurrence of urethral pathologic conditions have given rise to changes in the indications for tests for these conditions. In addition to being able to help confirm a diagnosis of VUR, the ceVUS technique can be used to depict obstructive and nonobstructive urethral pathologic conditions, as well as normal variants, on high-quality images. Furthermore, ceVUS enables real-time assessment of voiding function. For these reasons, ceVUS should be not only an alternative to voiding cystourethrography, but also the technique of choice for the study of the entire urinary tract in pediatric patients. Online supplemental material is available for this article. RSNA, 2017.
