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...

OBJECTIVES: Double J stent placement at kidney transplant may reduce stenosis or leakage complication rates. However, placement may also increase risk for early urinary tract infection (ie, < 3 mo after transplant). In children, the usefulness of double J stent placement is not well defined. MATERIALS AND METHODS: We analyzed retrospective data from children who received transplants at the Gazi University Transplantation Center and Pediatric Nephrology (Ankara, Turkey) for outcomes related to double J stents...

AIM: Clean catch urine (CCU) collection is commonly used in pre-continent children. CCU can be time-consuming and specimens may be contaminated. Our aim was to determine the time taken for CCU attempts and to describe the success of this method in diagnosing or excluding urinary tract infection. METHODS: Prospective observational study of CCU in pre-continent children aged 2-48 months in the emergency department. Time taken until urine collection, 'successful' (voided and caught), 'missed' (voided not caught) or the procedure 'stopped', were recorded and urine culture results analysed...

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...

INTRODUCTION: Complete primary repair of bladder exstrophy (CPRE) is widely used for classic bladder exstrophy (CBE) closure. Long-term renal function with or without dilation in these patients is poorly characterized and may be impacted by bladder storage parameters or recurrent urinary tract infections (UTIs). OBJECTIVE: We sought to assess our long-term experience with CPRE and investigate factors that may influence upper-tract deterioration. STUDY DESIGN: A retrospective review of patients at our institution with CBE undergoing CPRE from 1990 to 2015 was performed...

INTRODUCTION: Urinary tract infections (UTI) caused by Escherichia coli (E. coli) are common in patients with idiopathic hypercalciuria. As both UTI and hypercalciuria (prelithiasis) have a genetic basis, we wanted to know whether the family history of urolithiasis is more common in children with UTIs caused by E. coli. Secondarily, we wondered if the renal scars are more common in children with prelithiasis. MATERIAL AND METHODS: Ambispective study with collected data from 104 patients (40 male, 64 female) followed after having been diagnosed of UTI by E...

BACKGROUND: Reported rates of post-procedural urinary tract infection (ppUTI) after voiding cystourethrogram (VCUG) are highly variable (0-42%). OBJECTIVE: This study aimed to determine the risk of ppUTI after cystogram, and evaluate predictors of ppUTI. STUDY DESIGN: A retrospective cohort study of children undergoing VCUG or radionuclide cystogram (henceforth 'cystogram') was conducted. Children with neurogenic bladder who underwent cystogram in the operating room and without follow-up at the study institution were excluded...

INTRODUCTION: Urinary tract infections (UTI) are common infectious disorders, and obesity is an increasing public health problem worldwide. Several studies have suggested that childhood obesity may be associated with the development of UTI. However, the potential effects of obesity on the clinical outcomes of UTI in children remain unknown. MATERIALS AND METHODS: Hospital discharge records for patients aged 18 years or younger with a diagnosis of UTI were extracted from the 2012 Kids' Inpatient Database...

OBJECTIVES: Studies on the influence of mannose-binding lectin (MBL) deficiency on infection susceptibility in preterm infants have yielded controversial results. We investigated the association of genotype-based MBL levels with outcome in very-low-birth weight infants (VLBWI). METHODS: We genotyped 3 genetic variants of MBL2 (rs1800450, rs1800451, rs5030737) in 6878 VLBWI. MBL plasma levels were categorized as normal (wild type, A/A), low (heterozygotes, A/O) or undetectable (homozygotes, O/O)...

CONTEXT: Acute pyelonephritis may result in renal scarring. Recent prospective studies have shown a small benefit of antibiotic prophylaxis in preventing symptomatic and febrile urinary tract infections (UTIs), while being underpowered to detect any influence in prevention of renal damage. OBJECTIVES: Review of the literature and a meta-analysis to evaluate the effect of antibiotic prophylaxis on UTI-related renal scarring. DATA SOURCES: Medline, Embase, and Cochrane Controlled Trials Register electronic databases were searched for studies published in any language and bibliographies of identified prospective randomized controlled trials (RCTs) performed and published between 1946 and August 2016...

BACKGROUND: Clinically confirmed incidents of acute pyelonephritis (APN) following recurrent infections of urinary tract (UTI) form basic risk factors for renal scarring in children. Vesico-uretheral reflux (VUR) of higher grade is additional risk factor for this scarring. Opinions on diagnostic value of summed sequential images of renal uptake phase (SUM) of dynamic renal scintigraphy in detection of renal scars are diverse. However, several publications point to higher diagnostic efficacy of clearance parametric images (PAR) generated from this study...

Streptococcus pneumoniae infections in children are most often lung infections or meningitis. Urinary tract infections are much rarer. We present the case of a urinary tract infection with Streptococcus pneumoniae. The clinical picture was classical. The urine culture showed the presence of Streptococcus pneumoniae in urine (10(4) UFC/mL; with 2 × 10(4) leucocytes/mL). The literature mentions a few cases of such infections. In some studies, the prevalence of Streptococcus pneumoniae in urine of children is less than 1%...

Although carbapenem is the recommended for urinary tract infection (UTI) caused by extended-spectrum beta-lactamase (ESBL)-producing organisms, non-carbapenems have been reported to be effective for adult patients with UTI caused by ESBL-producing organisms. The purpose of this study was to evaluate the efficacy of non-carbapenems for pediatric patients with UTI due to ESBL-producing Escherichia coli (E. coli) based on the microbiologic and clinical outcomes. Fifteen children, who were treated for first febrile UTI caused by ESBL-producing E...

BACKGROUND: Vesicoureteric reflux (VUR) is an important association of paediatric urinary tract infection (UTI) found in 30-50% of all children presenting with first UTI. Contrast-enhanced voiding ultrasonography (ceVUS) has become an important radiation-free method for VUR detection in children. Its sensitivity in detecting VUR has greatly improved due to the development of the contrast-specific ultrasound techniques and the introduction of the second-generation ultrasound contrast agent, superseding the diagnostic accuracy of standard radiological procedures...

Recurrent urinary tract infections (UTIs) occur frequently in children and women. Intracellular bacterial communities (IBCs) and biofilm formation by Escherichia coli are risk factors for recurrence. The aim of this study was to evaluate the effect of different antibiotics on biofilms by E. coli strains isolated from children with UTI and to correlate virulence factors and IBCs with biofilm formation. A total of 116 E. coli strains were tested for biofilm formation using the crystal violet microplate technique...
