INTRODUCTION: Dimercaptosuccinic acid (DMSA) scintigraphy is the gold standard in the evaluation of renal parenchymal defects and is widely used in the pediatric population. As more recent ultrasound equipment was purchased at our tertiary pediatric centre, our objective was to evaluate if renal ultrasound (US) results are equivalent or sufficient when compared to DMSA scintigraphy in the assessment of renal anomalies. METHODS: The charts of all 463 patients who underwent DMSA scintigraphy between January 2009 and May 2014 at our pediatric tertiary centre were reviewed...

BACKGROUND: Intermittent catheterisation is a commonly recommended procedure for people with incomplete bladder emptying. There are now several designs of intermittent catheter (e.g. different lengths, 'ready to use' presentation) with different materials (e.g. PVC-free) and coatings (e.g. hydrophilic). The most frequent complication of intermittent catheterisation is urinary tract infection (UTI), but satisfaction, preference and ease of use are also important to users. It is unclear which catheter designs, techniques or strategies affect the incidence of UTI, which are preferable to users and which are most cost effective...

BACKGROUND: Urine biomarkers are commonly used in the evaluation of acute kidney injury, and are gaining attention as tools for studying urinary tract infections (UTIs). We analyzed neutrophil gelatinase-associated lipocalin (NGAL) and seven other urine biomarkers to evaluate their usefulness in the diagnosis of UTI in infants. METHODS: Eight urine biomarkers were analyzed in 108 infants with UTI. Controls were 64 febrile children without UTI and 13 healthy children...

INTRODUCTION: Patients with anorectal malformations (ARMs) have a high incidence of genitourinary anomalies. Those with a recto-bladder neck fistula may represent a high-risk group, but their long-term urologic outcomes are poorly described. OBJECTIVE: To evaluate the clinical and urodynamic outcomes in a large cohort of patients with an ARM subtype of recto-bladder neck fistula. MATERIALS AND METHODS: A retrospective cohort study was performed of patients who had been treated for a recto-bladder neck fistula at the present institution since 2007...

BACKGROUND: Acute pyelonephritis is associated with renal scarring in up to 30% of patients. Renal scarring may cause significant long-term morbidity. The pathogenesis of acute pyelonephritis remains unclear, although it involves interaction among uroepithelium, the immune system cells, and the locally produced cytokines. That some UTI-prone children develop acute pyelonephritis, and eventually renal parenchymal scarring, suggests a genetic role. Interleukin-6, interleukin-8, chemokine receptor-1 (CXCR1), and tumor necrosis factor-alpha (TNFα), the key regulators of the host immune responses, are proteins whose secretion is controlled by genes...

INTRODUCTION: Children with neurogenic bladder (NGB) often require a lifetime of clean intermittent catheterization (CIC), typically using uncoated catheters (UCs). Hydrophilic catheters (HCs) have lower friction than UCs with reported less damage to the urethra. The purpose of this study is to compare outcomes between these catheters. METHODS: An investigator-initiated, prospective, randomized clinical trial was conducted to compare HCs versus UCs. Children aged 2-17 years with NGB on CIC were enrolled for 1 year...

INTRODUCTION: There is no consensus regarding use of periprocedural antibiotics or routine urine cultures during urodynamics study (UDS) in children. At our hospital, we historically have obtained urine cultures during UDS. However, even with positive cultures, few patients require treatment. Most are successfully managed with increased hydration and frequent bladder emptying. PURPOSE: To evaluate clinical characteristics, antibiotic treatment, and outcomes in patients undergoing UDS to identify (1) risk factors for urinary tract infection (UTI) after UDS, and (2) patients who may benefit from routine urine culture...

BACKGROUND: Posterior urethral valve (PUV) is life-threatening congenital anomaly of the urinary tract that results in vesicoureteric reflux, recurrent UTI, voiding dysfunction and renal insufficiency if not treat timely. Endoscopic ablation of posterior urethral valves using cold knife or laser is the current gold standard therapy. Many urologists go for repeat cystoscopy to see residual valve or stricture while others repeat VCUG to measure the posterior to anterior urethral ratio for residual obstruction...

BACKGROUND: Acute focal bacterial nephritis (AFBN) is a severe form of upper urinary tract infection (UTI) with neurological manifestations and focal renal mass lesions on computed tomography (CT). Prolonged antibiotic therapy may improve the renal outcome, but the early differential diagnosis of AFBN from acute pyelonephritis (APN) is challenging. We searched for effective biomarkers of AFBN based on the pathophysiology of upper UTIs. METHODS: Of 52 upper UTI cases treated at Yamaguchi University between 2009 and 2016, 38 pediatric patients with AFBN (n=17) or APN (n=21) who underwent ultrasonography and/or CT were enrolled...

BACKGROUND: Our objective was to analyze the evolution of kidney damage over time in small children with urinary tract infection (UTI) and factors associated with progression of renal damage. METHODS: From a cohort of 1003 children <2 years of age with first-time UTI, a retrospective analysis of 103 children was done. Children were selected because of renal damage at index (99m)Tc-dimercaptosuccinic acid (DMSA) scintigraphy at least 3 months after UTI, and a late DMSA scan was performed after at least 2 years...

INTRODUCTION: The risk of post-procedural urinary tract infection (ppUTI) after retrograde urethrogram (RUG) has not been well quantified. Prophylactic antibiotics may reduce the risk, but must be weighed against the risks of antibiotic resistance. Prior research has shown that this risk is variable after voiding cystourethrogram (0-42% reported ppUTI rate) and appears to be low after urodynamics (0-4.8%) but this risk has not been well documented for patients undergoing RUG. OBJECTIVE: We aimed to (1) describe the rate of ppUTI after RUG, and (2) examine factors associated with use of antibiotics at the time of RUG...

PURPOSE: Vesico-ureteral reflux (VUR) represents one of the most significant risk factors for acute pyelonephritis in children. Surgery is an important part of its management. Laparoscopic ureteric reimplantation using the Lich-Gregoir technique is an option for VUR. The aim of this study is to assess short- and medium-term outcomes of this approach. MATERIALS AND METHODS: This is a retrospective study including all children with VUR treated by laparoscopic extravesical ureteral reimplantation with the Lich-Gregoir technique in University Hospital of Saint-Etienne from August 2007 to May 2016...

Urinary tract infections (UTI) are the most common infectious diseases in children. Urosepsis in childhood, though rare, is the most complicated possible variant. In newborns and infants, unspecific symptoms are a significant barrier to a fast and reliable diagnosis, which is crucial to successful treatment. In addition to urine and laboratory tests as well as non-invasive examinations (ultrasound), there may be an indication for invasive examinations of the kidneys (DMSA scans) in cases of a severe infection...

REVIEW
Jathin Bandari, Steven G Docimo
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...

REVIEW
Ahmed Abdelhalim, Antoine E Khoury
Vesicoureteral reflux (VUR) has been linked to recurrent urinary tract infections (UTIs), renal scarring, hypertension, renal insufficiency and end-stage kidney disease. Different imaging strategies have been proposed to approach children presenting with UTI to sort out patients with significant VUR while minimizing patient morbidity, radiation exposure and financial burden. None of these imaging strategies is universally accepted. The"top-down approach" (TDA) aims at restricting the number of voiding cystourethrograms (VCUGs) and its associated morbidity while identifying patients with clinically-significant reflux...

BACKGROUND: Renal and bladder ultrasound (RBUS) is recommended in evaluation of children after an initial, febrile urinary tract infection. Although it is not uncommon to observe debris within the bladder lumen on sonography, the significance of this finding is uncertain. Debris may be interpreted as an indication of ongoing infection, but there have been no studies to date investigating the association of bladder debris with a positive culture. OBJECTIVE: The aim of this study was to evaluate the association of bladder debris noted at the time of RBUS with positive urine culture results obtained from a catheterized specimen, among patients undergoing RBUS and voiding cystourethrogram (VCUG) on the same day...
