Abstract
Voiding cystourethrography (VCUG) is a fluoroscopic technique that allows the assessment of the urinary tract, including the urethra, bladder, and-if vesicoureteral reflux (VUR) is present-the ureters and the pelvicalyceal systems. The technique also allows for the assessment of bladder filling and emptying, providing information on anatomical and functional aspects. VCUG is, together with contrast-enhanced voiding urosonography (VUS), still the gold standard test to diagnose VUR and it is one of the most performed fluoroscopic examinations in pediatric radiology departments. VCUG is also considered a follow-up examination after urinary tract surgery, and one of the most sensitive techniques for studying anatomy of the lower genitourinary tract in suspected anatomical malformations. The international reflux study in 1985 published the first reflux-protocol and graded VUR into five classes; over the following years, other papers have been published on this topic. In 2008, the European Society of Paediatric Radiology (ESPR) Uroradiology Task Force published the first proposed VCUG Guidelines with internal scientific society agreement. The purpose of our work is to create a detailed overview of VCUG indications, procedural recommendations, and to provide a structured final report, with the aim of updating the 2008 VCUG paper proposed by the European Society of Paediatric Radiology (ESPR). We have also compared VCUG with contrast-enhanced VUS as an emergent alternative. As a result of this work, the ESPR Urogenital Task Force strongly recommends the use of contrast-enhanced VUS as a non-radiating imaging technique whenever indicated and possible.

Abstract
Although investigations over the past 2 decades have improved our understanding of the natural history of vesicoureteral reflux (VUR) and helped identify those at higher risk of both VUR itself as well as its potential severe sequelae, debate exists regarding key aspects of care, including when to perform diagnostic imaging and which patients benefit from continuous antibiotic prophylaxis. Artificial intelligence and machine learning have the potential to distill large volumes of granular data into practical tools that clinicians can use to guide diagnosis and management decisions. Surgical treatment, when indicated, remains highly effective and is associated with low morbidity.

Abstract
AIM To determine the prevalence of familial vesicoureteric reflux (VUR) by studying the outcomes of screening in a contemporary cohort of newborns with normal antenatal kidney scans. METHODS A review of screening outcomes in newborns with a first degree relative with VUR, normal antenatal scans and no prior urine infections between 2014-2019 at three maternity units in the North East of England was conducted. Imaging consisted of micturating cystourethrogram (MCUG) in all and renal tract ultrasound scan (RUS) routinely in two units and by clinician preference in one unit. RESULTS At a median age of 59 days, 265 infants underwent MCUG. High-grade VUR (Grades 3-5) was detected in 13 (4.9%) and low-grade VUR (Grades 1-2) in 24 (9.1%). In the 152 infants who had a RUS, abnormalities were detected in 21 (13.8%). An abnormal postnatal RUS has a low positive predictive value (14.3%) for high-grade VUR, but a normal RUS has a high negative predictive value (95.4%). CONCLUSION Compared to historical cohorts from two decades ago, the yield from familial VUR screening is low and unjustifiable in the setting of normal antenatal anomaly scans.

Abstract
Introduction Vesicoureteral Reflux (VUR) is characterized by a retrograde flow of urine from the bladder into the ureters and kidneys. It is one of the most common urinary tract anomalies and the major cause of urinary tract infection (UTI) in the first years of life. If not properly diagnosed and treated can lead to recurrent UTI, renal scar and, in severe cases, to end stage renal disease. Despite recent advances in scientific and technological knowledge, evaluation and treatment of VUR is still controversial and there is still considerable heterogeneity in evaluation methods and therapeutic approaches. The aim of the present consensus is to give a practical orientation on how to evaluate and treat VUR. Methods The board of Pediatric Urology of the Brazilian Society of Urology joined a group of experts and reviewed all important issues on Vesicoureteral Reflux evaluation and treatment and elaborated a draft of the document. On November 2017 the panel met to review, discuss and write a consensus document. Results and Discussion Vesicoureteral Reflux is a common and challenging problem in children. Children presenting with Vesicoureteral Reflux require careful evaluation and treatment to avoid future urinary tract infections and kidney scars. The panel addressed recommendations on up to date choice of diagnosis evaluation and therapies.

Abstract
CONTEXT Vesicoureteral reflux (VUR) remains the most interesting topic of pediatric urology due to the dynamic nature of recent controversial publications. Starting from the need for a diagnosis to the necessity and effectiveness of treatment in preventing scars, VUR remains in the mist. Although recent strong evidence helped as fog lights in this blurriness, more data are required for achieving crystal clearance. This article aims to summarize and discuss the current state of the evidence regarding VUR management. OBJECTIVE To provide a comprehensive synthesis of the main evidence in the literature on the current and contemporary management of VUR in children; to discuss conservative management with continuous antibiotic prophylaxis (CAP), especially its effectiveness and safety; and to review the current evidence regarding contemporary surgical techniques. EVIDENCE ACQUISITION We conducted a nonsystematic review of the literature using the recent guidelines and PubMed database regarding surveillance, CAP, endoscopic, open, laparoscopic, and robot-assisted ureteral surgical treatment. EVIDENCE SYNTHESIS Despite the striking results of previous studies revealing the ineffectiveness of CAP, more recent studies and their two fresh meta-analyses revealed a positive role for CAP in the contemporary management of VUR. One of the most interesting findings is the redundant rising of endoscopic correction and its final settlement to real indicated cases. Patient individualization in the contemporary management of VUR seems to be the keyword. The evidence in the literature showed a safe and effective use of laparoscopic and robot-assisted laparoscopic reimplantations. CONCLUSIONS The goal of VUR treatment is to prevent the occurrence of febrile urinary tract infections and formation of scars in the renal parenchyma. The approach should be risk adapted and individualized according to current knowledge. Individual risk is influenced by the presentation age, sex, history of pyelonephritis and renal damage, grade of reflux, bladder bowel dysfunction, and circumcision status. PATIENT SUMMARY Vesicoureteral reflux is a nonphysiological reflux of urine from the bladder through the ureters to the kidney. Treatment depends on the presentation of the vesicoureteral reflux (VUR). Therapeutic options range from watchful waiting to open surgery. This article aims to summarize and discuss the current state of the evidence regarding VUR management.

Abstract
Paediatric urological surgery is often required for managing congenital and acquired disorders of the genitourinary system. In this Series paper, we highlight advances in the surgical management of six paediatric urological disorders. The management of vesicoureteral reflux is evolving, with advocacy ranging from a less interventional assessment and antimicrobial prophylaxis to surgery including endoscopic injection of a bulking agent and minimally invasive ureteric reimplantation. Evidence supports early orchidopexy to improve fertility and reduce malignancy in boys with undescended testes. A variety of surgical techniques have been developed for hypospadias, with excellent outcomes for distal but not proximal hypospadias. Pelvi-ureteric junction obstruction is mostly detected prenatally; indications for surgery have been refined with evidence, and minimally invasive pyeloplasty is now standard. The outlook for patients with neurogenic bladder has been transformed by a combination of clean intermittent catheterisation, algorithms of diagnostic investigations, and innovative medical and surgical therapies. Posterior urethral valves are associated with considerable mortality; fetal diagnosis allows stratification of candidates for intervention, but ongoing bladder dysfunction in patients after valve ablation remains a cause of long-term morbidity.

Abstract
We performed a review of the recent literature concerning urinary tract infection (UTI) evaluation and management. In modeling options for management, one overriding conclusion became apparent: in most affected children, the presence of vesicoureteral reflux (VUR) is inconsequential since it has no bearing on optimal management or outcome. In fact, knowing that a child does not have reflux might bias the provider to withhold potentially helpful therapeutic modalities to decrease UTI morbidity, such as antibiotic prophylaxis. In this review, we will propose that evaluation for VUR is not necessary or helpful except in the small subset of children whose UTIs have proven refractory to management of their other risk factors.
