Vesicoureteric reflux

Matthew D Timberlake, Craig A Peters
PURPOSE OF REVIEW: Although open ureteral reimplantation remains the gold standard for surgical correction of vesicoureteral reflux (VUR), robotic-assisted laparoscopic ureteral reimplantation (RALUR) holds promise and is becoming more widely utilized. The present article outlines primary operative techniques for RALUR, summarizes the current literature with respect to surgical outcomes and costs, and discusses early applications of RALUR to complex and reoperative cases. RECENT FINDINGS: Intravesical and extravesical techniques for RALUR have been described...

Acquired renal scarring occurs in a subset of patients following febrile urinary tract infections and is associated with hypertension, proteinuria, and chronic kidney disease. Limited knowledge of histopathology, immune cell recruitment and gene expression changes during pyelonephritis restricts the development of therapies to limit renal scarring. Here, we address this knowledge gap using immunocompetent mice with vesicoureteral reflux. Transurethral inoculation of uropathogenic Escherichia coli in C3H/HeOuJ mice leads to renal mucosal injury, tubulointerstitial nephritis, and cortical fibrosis...

AIM: This study evaluated the controversial relationship between the duration of fever before treatment initiation (FBT) for a febrile urinary tract infection (UTI), with renal scarring based on dimercaptosuccinic acid scintigraphy (DMSA) findings. METHODS: The inpatient records of 148 children under two years of age with a first episode of febrile UTI were analysed. Acute and repeat DMSA findings, clinical and laboratory parameters were evaluated. RESULTS: Acute DMSA showed that 76 of the 148 children with a febrile UTI had renal lesions: 20 were mild and 56 were moderate or severe...

BACKGROUND: The advent of online task-distribution has opened a new avenue to efficiently gather community perspectives needed for utility estimation. Methodological consensus for estimating pediatric utilities is lacking, with disagreement over whom to sample, what perspective (patient vs. parent), and whether instrument-induced anchoring bias is significant. We sought to determine what methodological factors potentially impact utility estimates for vesicoureteral reflux (VUR). DESIGN: Cross-sectional surveys using a time-trade-off (TTO) instrument were conducted via Amazon's Mechanical Turk online interface; respondents were randomized to answer questions from child, parent, or dyad perspectives on the utility of a VUR health state and one of three "warm-up" scenarios (paralysis, common cold, none) prior to a VUR scenario...

This study was performed to evaluate the role of postnatal ultrasonography (US) in predicting the final diagnosis and need of surgery of antenatal hydronephrosis patients. One hundred and twenty six renal units (RUs) of 76 patients with diagnosis of antenatal hydronephrosis (ANH) were studied. An early postnatal US no later than the first week of life was requested. Voiding cystourethrography (VCUG) and/or diuretic renogram (MAG3) was performed in children who had persistent or worsening hydronephrosis to make a certain diagnose of etiology...

Double-J ureteral stents disposal is associated with the appearance of side effects in up to 90% of the patients. The main causes of these symptoms are related to stent's design and the materials they are manufactured from. Vesicoureteral reflux and bladder trigone irritation are the etiopathogenic causes of ureteral stents associated morbidity. Due to this, and in order to improve patients' quality of life, stents that avoid reflux have been developed. Among anti-reflux designs, the first was a double-J stent the bladder tip of which is provided with a polymeric membrane that prevents retrograde flow of urine through its internal drainage channel...

The use of double J catheters is usual in urologist's daily practice. The indication can be divided in prophylactic or therapeutic. Prophylactically, they prevent complications derived from endourological procedures, such as ureteral lesion or obstructive uropathy secondary to residual lithiasis or edema. Therapeutically, they treat obstructive uropathy of many different pathologies, either in an emergency setting or scheduled, such as lithiasis, stenosis, extrinsic compression of any nature or urinary tract tumors among others...

Urinary tract infections (UTIs) represent a common bacterial cause of febrile illness in children. Of children presenting with a febrile UTI, 25-40% are found to have vesicoureteral reflux (VUR). Historically, the concern regarding VUR was that it could lead to recurrent pyelonephritis, renal scarring, hypertension, and chronic kidney disease. As a result, many children underwent invasive surgical procedures to correct VUR. We now know that many cases of VUR are low-grade and have a high rate of spontaneous resolution...

OBJECTIVE: To explore the potential value of an objective assessment, renal parenchyma-to-hydronephrosis area ratio (PHAR), as an early predictor of surgery. MATERIALS AND METHODS: Initial sagittal renal ultrasound images of patients prospectively entered into a prenatal hydronephrosis (PHN) database from January 2008-2016 with baseline SFU grades III and IV PHN, without vesicoureteral reflux, were evaluated using NIH-sponsored image-processing software. PHAR, APd, SFU grade and urinary tract dilation (UTD) risk categories were contrasted with nuclear scan data (differential renal function [DRF] and drainage time [t ½]), and analyzed for predictive value in determining the decision to proceed with surgery by drawing receiver operator characteristic curves...

OBJECTIVES: To describe renal ultrasound (RUS) and voiding cystourethrogram (VCUG) findings and determine predictors of abnormal imaging in young infants with bacteremic urinary tract infection (UTI). METHODS: We used retrospective data from a multicenter sample of infants younger than 3 months with bacteremic UTI, defined as the same pathogenic organism in blood and urine. Infants were excluded if they had any major comorbidities, known urologic abnormalities at time of presentation, required intensive unit care, or had no imaging performed...

Dextranomer/hyaluronic acid copolymer (Deflux) first received FDA approval in 2001 for endoscopic injection in children with grade II-IV vesicoureteral reflux (VUR). As experience has grown, Deflux has been used more liberally with encouraging results. We report three cases where Deflux was used in off-label fashion, resulting in delayed ureteral obstruction and loss of renal function (range 18-52 months post-operatively). We now place increased emphasis on the need for long-term follow-up after Deflux in both routine and complex cases, particularly in situations of off-label use...

PURPOSE: Autologous cells potentially provide an ideal injectable substance for management in vesicoureteral reflux (VUR). The aim of this study is to examine the effects of mature adipocyte-derived dedifferentiated fat (DFAT) cell transplantation on VUR in a rat bladder pressurization-induced VUR model. METHODS: To create VUR, Sprague-Dawley rats underwent urethral clamping and placement of cystostomy followed by intravesical pressurization. Rat DFAT cells (1 × 10(6) cells, DFAT group, n = 5) or saline (control group, n = 5) was then injected into the bilateral vesicoureteral junctions...

OBJECTIVES: To assess the need for implementing renal scintigraphy in the diagnosis of the multicystic dysplastic kidney (MCDK) and the safety of its conservative treatment. MATERIAL AND METHODS: A retrospective study of patients with unilateral MCDK was conducted at our centre from January 2005 to August 2015. We calculated the positive predictive value (PPV) of ultrasonography, taking renal scintigraphy and pathology as the gold standard. We calculated a survival curve according to the Kaplan-Meier method to assess the annual probability of spontaneous resolution of the multicystic kidney...

INTRODUCTION: Voiding cystourethrography (VCUG) is the modality of choice to diagnose vesicoureteral reflux (VUR). Although grading of VUR is essential for prognosis and clinical decision-making, the inter-observer reliability for grading has been shown to vary substantially. The Randomized Intervention for Children with VesicoUreteral Reflux (RIVUR) trial provides a large cohort of children with VUR to better understand the reliability of VCUG findings. OBJECTIVE: To determine the inter-observer consistency of the grade of VUR and other VCUG findings in a large cohort of children with VUR...

Bladder diverticula in children are mostly congenital, frequently associated with vesicoureteral reflux. Their positive diagnosis is based primarily on retrograde urethrocystography. One complication of this condition is acute urinary retention. We report the case of a 4-month-old infant who presented acute retention of urine secondary to bilateral congenital bladder diverticulum and review the literature on this subject.
