Objective Boys with posterior urethral valves (PUV) present an increased risk of febrile urinary tract infection (fUTI). Identifying specific risk factors could allow for tailoring UTI prevention. The aim of this study was to use the data from the CIRCUP randomized controlled trial data to identify patient characteristics associated with a higher r...

Convolutional neural networks (CNNs) have proven to be efficient tools for image segmentation when a large number of segmented images are available. However, when the number of segmented images is not so large, the CNN segmentations are less accurate. It is the case for nephroblastoma (kidney cancer) in particular. When a new patient arrives, the e...

Objective Despite recent progress in caring for patients born with esophageal atresia (EA), undernutrition and stunting remain common. Our study objective was to assess nutritional status in the first year after birth with EA and to identify factors associated with growth failure. Study design We conducted a population-based study of all infants b...

Le néphroblastome (ou tumeur de Wilms) est la tumeur rénale maligne la plus fréquemment rencontrée chez l’enfant. Les progrès réalisés dans les dernières décennies concernant sa prise en charge diagnostique et thérapeutique ont permis d’améliorer son pronostic avec à l’heure actuelle une survie à 5 ans dépassant 90% tous stades confondus. Cependant...

Background Ovarian mature teratoma (OMT) is a common ovarian tumor found in the pediatric population. In 10%–20% of cases, OMT occurs as multiple synchronous or metachronous lesions on ipsi- or contralateral ovaries. Ovarian-sparing surgery (OSS) is recommended to preserve fertility, but total oophorectomy (TO) is still performed. Design This stud...

Background Boys with posterior urethral valves (PUVs) have an increased risk of febrile urinary tract infections (fUTIs). Circumcision is believed to reduce the risk of fUTIs in boys, although there are no randomized trials demonstrating this. Objective To determine the effect of circumcision on the risk of fUTIs in boys with PUVs. Design, settin...

Background and objectives: Respiratory diseases are common in children with esophageal atresia (EA), leading to increased morbidity and mortality in the first year. The primary study objective was to identify the factors associated with readmissions for respiratory causes in the first year in EA children. Methods: A population-based study. We in...

Objective To identify the risk factors for early mortality and morbidity in a population with distal esophageal atresia (EA)-tracheoesophageal fistula. Study Design Cohort study from a national register. Main outcomes and measures included early mortality, hospital length of stay, need for nutritional support at 1 year of age as a proxy measure of...

Aim: To compare the results of B-Mode ultrasound and contrast-enhanced ultrasonography for the diagnosis of ovarian torsion in children. Methods: We conducted a retrospective clinical study. Patients under 18 years old referred in emergency with a suspected diagnosis of ovarian torsion and who had undergone both B-Mode ultrasound and contrast-enha...

Male congenital urethral fistula is an extremely rare condition. It is characterized by an abnormal opening of the ventral aspect of the penis. We report the case of a 1-month-old boy with congenital urethral fistula. We will describe the surgical technique, postoperative results, and literature review. 1. Introduction Male congenital urethral fis...

Introduction Wilms’ tumor (WT) is the most common type of malignant kidney tumor in children. Three-dimensional reconstructions can be performed pre-operatively to help surgeons in the planning phase. Objectives The main objective of this study was to determine the variability of WT segmentation and 3D reconstruction. The secondary objectives were...

This report is aimed at opening a new reflexion about exploration of fetal lungs malformations with 2‐D ultrasound shear wave elastography (2D‐SWE) in two fetuses. These preliminary results are drawn from the ELASTOMAP study, which was designed to explore feasibility of 2D‐SWE on fetal lungs. Fetus A presented Congenital Pulmonary Airway Malformati...

Aim of the Study: We described the initial experience of four referral centers in the treatment of primary obstructive megaureter (POM) in children, by high-pressure balloon dilatation (HPBD) of the ureterovesical junction with double JJ stenting.
