Unilateral open extravesical ureteral reimplanation with contralateral dextronomer/hyaluronic acid injection performed as an outpatient therapy.

J Pediatr Urol 2018 Dec 25;14(6):566.e1-566.e5. Epub 2018 Jul 25.

University of Utah/Primary Children's Hospital, 100 N Capecchi Dr #2200, Salt Lake City, UT, USA.

Introduction: Historically, patients with unilateral high-grade vesicoureteral reflux (VUR) and contralateral low-grade or resolved VUR have been treated with bilateral intravesical ureteral reimplantation, which requires postoperative admission. If the high-grade VUR side is treated alone, then the contralateral side is at risk of developing recurrent or worsening VUR. Bilateral subureteric injection of dextronomer/hyaluronic acid (DHA) is another option that can be performed as an outpatient therapy, but a single injection is less effective for high-grade VUR.

Anatomic findings associated with epispadias in boys: Implications for surgical management and urinary continence.

J Pediatr Urol 2018 Feb 26;14(1):42-46. Epub 2017 Oct 26.

Department of Urology, Boston Children's Hospital, Boston, MA, USA.

Introduction: Pre-operative physical examination of male epispadias allows for classification of epispadias level as glanular (GE), penile (PE) or penopubic (PPE), and for delineation of anatomic anomalies. The incidence of associated extragenital abnormalities, such as vesicoureteral reflux (VUR), bladder neck (BN) abnormality and abnormal pubic diastasis (PD), and their impact on urinary continence has not yet been systematically studied.

Objective: The goal of this study was to evaluate whether the more proximal level of epispadias correlated with associated extragenital anatomic anomalies seen on initial imaging or endoscopic evaluation, and whether these pre-operative findings contributed to subsequent surgical management and impacted on achieving urinary continence.

Contrast-enhanced Voiding Urosonography for Vesicoureteral Reflux Diagnosis in Children.

Radiographics 2017 Oct;37(6):1854-1869

From the Department of Radiology, UDIAT Centre Diagnòstic, Parc Taulí Hospital Universitari, Institut d'Investigació Parc Taulí I3PT, Universitat Autònoma de Barcelona, Parc Taulí 1, Sabadell 08208, Spain.

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. Read More
