Knowledge of vesicoureteral reflux obtained by screening voiding cystourethrogram in children with multicystic dysplastic kidney does not change patient management or prevent febrile urinary tract infection.

J Pediatr Urol 2019 Mar 22. Epub 2019 Mar 22.

Nationwide Children's Hospital, 700 Children's Drive, Columbus, OH 43205, USA.

Introduction: While children with multicystic dysplastic kidneys (MCDK) are predisposed to contralateral kidney (CK) vesicoureteral reflux (VUR), it is unknown if this results in an increased risk of urinary tract infection (UTI). The authors hypothesized that knowledge of VUR via voiding cystourethrogram (VCUG) would enable altered practices to prevent UTI and thus reduce the number of febrile urinary tract infections (fUTIs).

Methods: The authors performed a retrospective chart review of all patients at their institution of multiple providers caring for patients with a diagnosis of MCDK from 1/1/07 to 7/14/17. Read More

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.

Ultrasound follow-up of an unusual giant urinoma in a newborn.

J Ultrasound 2018 Mar 16;21(1):65-68. Epub 2016 Dec 16.

Neonatal Intensive Care Unit, Azienda Istituti Ospitalieri di Cremona, Viale Priori, 1-26100, Cremona, Italy.

Urinoma, defined as an encapsulation of urine caused by urine extravasation into the perirenal space either through rupture of a calyceal fornix or a tear in the renal parenchyma, is an uncommon finding in prenatal diagnosis and the neonatal period. Urinoma can be associated with any urinary tract obstruction, or, as reported in several published cases, related to vesicoureteral reflux, kidney dysplasia, or complication arising during amniocentesis. We report on a newborn with a perinatal urinoma, with initial slight corpusculated fluid associated with nonobstructive and nonrefluxing megaureter, and no signs of kidney dysplasia. Read More
