Vet Radiol Ultrasound 2020 May 27. Epub 2020 May 27.

School of Veterinary Medicine, Aristotle University of Thessaloniki, Stavrou Voutira, Thessaloniki, Greece.

Contrast-enhanced voiding urosonography (CE-VUS) has been generally considered as a promising tool to diagnose vesicoureteral reflux and abnormalities in lower urinary tract in human patients, especially in children. The purpose of this prospective study is to evaluate the quality of images of the urinary bladder and urethra obtained by CE-VUS using a second-generation ultrasound contrast agent (SonoVue®) in healthy dogs and to investigate the safety profile of SonoVue® after intravesical administration. Eighty-four CE-VUS examinations with SonoVue® were successfully performed in both unsedated (39/84) and sedated (45/84) dogs. Read More

Introduction: Vesicoureteral reflux (VUR) is a common pediatric urologic condition associated with urinary tract infection and pyelonephritis. It can be diagnosed via fluoroscopic voiding cystourethrogram (VCUG) and, more recently, contrast-enhanced voiding ultrasonography (ceVUS), which does not expose the patient to ionizing radiation. Voiding urosonography contrast agents used for the diagnosis of VUR have been widely available in Europe but were approved by the Food and Drug Administration for use in the United States only in 2016.

The use of rotational fluoroscopy and 3-D reconstruction in the diagnosis and surgical planning for complex cloacal malformations.

J Pediatr Surg 2019 Aug 4;54(8):1590-1594. Epub 2019 Apr 4.

Center for Colorectal and Pelvic Reconstruction (CCPR), Nationwide Children's Hospital, Children's Drive Columbus, OH 43205, USA.

Introduction: Cloacal malformations, a confluence of the urinary tract, vagina and rectum into a single common channel, has a broad and complex anatomic spectrum requiring an imaging tool for visualization, measurement, and surgical planning for the reconstruction of these structures. We evaluated the role of 3-D fluoroscopy for this purpose, as it offers a combination of spatial correlation with precise anatomic measurements.

Methods: We examined our imaging protocol for patients with a cloacal malformation and report our experience with rotational fluoroscopy and 3-D reconstruction in 16 consecutive patients referred for cloacal reconstruction. Read More

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 May 22;15(3):267.e1-267.e5. 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

Targeted Workup after Initial Febrile Urinary Tract Infection: Using a Novel Machine Learning Model to Identify Children Most Likely to Benefit from Voiding Cystourethrogram.

Authors:

J Urol 2019 07 7;202(1):144-152. Epub 2019 Jun 7.

Department of Urology, Boston Children's Hospital , Boston , Massachusetts.

Purpose: Significant debate persists regarding the appropriate workup in children with an initial urinary tract infection. Greatly preferable to all or none approaches in the current guideline would be a model to identify children at highest risk for a recurrent urinary tract infection plus vesicoureteral reflux to allow for targeted voiding cystourethrogram while children at low risk could be observed. We sought to develop a model to predict the probability of recurrent urinary tract infection associated vesicoureteral reflux in children after an initial urinary tract infection. Read More
