[Bradis anti-reflux ureterocysto-anastomosis in children with recurrent obstructive megaureter].

Urologiia 2022 May(2):5-10

Rostov State Medical University of the Russian Federation Ministry of Public Health, Rostov-on-Don, Russia.

Introduction: Congenital ureterovesical junction (UVJ) obstructions quite rarely serve as an indication for ureteral reimplantation, and recurrent obstructions resulting from surgical treatment are even less frequent. Cases of acquired UVJ obstruction following endoscopy and ureteral reimplantation done for vesicoureteral reflux correction are fairly rare. The lack of known publications analyzing treatment of recurrent obstructive megaureter predetermines topicality of our research. Read More

Prenatal hydronephrosis: Bridging pre- and postnatal management.

Prenat Diagn 2022 Feb 14. Epub 2022 Feb 14.

Division of Urology, Hospital for Sick Children and University of Toronto, Toronto, Ontario, Canada.

Urinary tract dilation (UTD), including hydronephrosis (HN) is the most common prenatally detected anomaly and affects up to 1%-2% of pregnancies. Postnatally, it resolves without surgical intervention in approximately 75%-80% of children, however this may take several years to occur, necessitating repeated clinic visits and additional invasive testing for many. For the remainder, a surgical intervention will be offered to relieve obstruction or to correct vesicoureteral reflux. Read More

Pediatric Nephrology Unit, Dana-Dwek Children's Hospital, Tel Aviv Sourasky Medical Center.

Introduction: Distended fetal bladder, also known as fetal megacystis, usually points to lower urinary tract obstruction (LUTO) which is most commonly caused by posterior urethral valves (PUV) in the male fetus. We present a short case-series of fetal megacystis without oligohydramnion where primary vesicoureteral reflux (VUR) was the leading aetiology. These cases also displayed a high rate of kidney dysplasia with early-onset renal dysfunction. Read More

Evaluating the accuracy of simplified VCUG in comparison with traditional VCUG for diagnosis of urinary-reflux in children: Radiation dose reduction.

J Med Imaging Radiat Sci 2022 03 18;53(1):102-106. Epub 2021 Nov 18.

Medical Imaging Research Center, Shiraz University of Medical Sciences, Shiraz, Iran; Nuclear Medicine and Molecular Imaging Research Center, Namazi Teaching Hospital, Shiraz University of Medical Sciences, Shiraz, Iran. Electronic address:

Introduction: Voiding cystourethrogram (VCUG) is an imaging technique for diagnosing urinary-reflux. VCUG requires X-ray exposure, increasing the risk of malignancies induced by ionizing radiation, especially in children. Considering the importance of early diagnosis of urinary-reflux using VCUG to prevent kidney complications and the significance of reducing the radiation dose during this imaging, this study intends to reduce the imaging views of VCUG and evaluate the urinary-reflux, using a reduced number of images.

Contrast-enhanced ultrasound: a comprehensive review of safety in children.

Pediatr Radiol 2021 Nov 30;51(12):2161-2180. Epub 2021 Oct 30.

Department of Radiology, Children's Hospital of Philadelphia, 3401 Civic Center Blvd., Philadelphia, PA, 19104, USA.

Contrast-enhanced ultrasound (CEUS) has been increasingly used in pediatric radiology practice worldwide. For nearly two decades, CEUS applications have been performed with the off-label use of gas-containing second-generation ultrasound contrast agents (UCAs). Since 2016, the United States Food and Drug Administration (FDA) has approved the UCA Lumason for three pediatric indications: the evaluation of focal liver lesions and echocardiography via intravenous administration and the assessment of vesicoureteral reflux via intravesical application (contrast-enhanced voiding urosonography, ceVUS).

Magnetic Agarose Microspheres/Hyaluronic Acid Hydrogel as a Trackable Bulking Agent for Vesicoureteral Reflux Treatment.

Front Bioeng Biotechnol 2021 7;9:746609. Epub 2021 Oct 7.

State Key Laboratory of Molecular Engineering of Polymers, Department of Macromolecular Science, and Laboratory of Advanced Materials, Fudan University, Shanghai, China.

Vesicoureteral reflux (VUR) is one of the most common congenital anomalies in the kidney and the urinary tract. Endoscopic subureteral injection of a bulking agent has become popular in VUR treatment due to its high success rates, few complications, and a straightforward procedure. In this study, a novel magnetic bulking agent was prepared by embedding FeO magnetic nanoparticles in cross-linked agarose microspheres with diameters of 80-250 μm and dispersing the magnetic microspheres in a hyaluronic acid hydrogel.

Kidney and urinary tract findings among patients with Kabuki (make-up) syndrome.

Pediatr Nephrol 2021 12 27;36(12):4009-4012. Epub 2021 Sep 27.

Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel.

Background: Kabuki syndrome (KS) is a genetic disorder caused mainly by de novo pathogenic variants in KMT2D or KDM6A, characterized by recognizable facial features, intellectual disability, and multi-systemic involvement, including short stature, microcephaly, hearing loss, cardiac defects, and additional congenital anomalies. While congenital anomalies of the kidneys and urinary tract (CAKUT) are known manifestations of this disorder, studies focused solely on kidney involvement are scarce, and its prevalence is most likely underestimated. This study aimed to describe the prevalence and nature of CAKUT and other renal manifestations, in a cohort of KS patients followed at a single tertiary center. Read More
