BACKGROUND: Patients with acute lobar nephronia (ALN) require a longer duration of antimicrobial treatment than those with acute pyelonephritis (APN), and ALN is associated with renal scarring. The aim of this study was to provide an understanding of ALN by comparing the clinical features of pediatric patients with ALN and APN. METHODS: We enrolled all of the patients with ALN (confirmed by computed tomography) admitted to our hospital from 1999 to 2012 in the ALN group...

BACKGROUND/PURPOSE: This aim of this study was to assess the clinical manifestations, the microorganisms involved and their antibiotic resistance in children hospitalized due to acute lobar nephronia (ALN) and non-ALN community-acquired urinary tract infections (UTIs). METHODS: We retrospectively reviewed the records of 265 previously healthy children hospitalized due to a first-episode of community-acquired febrile UTI between July 2004 and June 2007. Based on the results of renal ultrasonography and computed tomography, they were divided into ALN and non-ALN groups...

BACKGROUND: Despite recent advances in molecular epidemiology and pathogenecity analyses of extraintestinal Escherichia coli infections, detailed analyses identifying virulence factors of E. coli isolates from pediatric urosepsis patients have not been reported. This study was conducted to explore and differentiate bacterial virulence factors associated with urosepsis and 2 other severe parenchymal infections, acute pyelonephritis (APN) and acute lobar nephronia (ALN), in pediatric patients...

BACKGROUND: Acute lobar nephronia (ALN) is a severe nonliquefactive inflammatory renal bacterial infection, and requires a longer duration of treatment. The aim of this prospective study was to investigate renal scarring after ALN and to examine the risk factors for renal scarring in children with ALN compared with those with acute pyelonephritis (APN). METHODS: Patients with computed tomography-diagnosed ALN were enrolled and randomly allocated, with serial entry, to either a 2- or 3-week antibiotic treatment regimen...

BACKGROUND: : Acute lobar nephronia (ALN) is a complicated acute renal infection that is part of the progression of the inflammatory process of acute pyelonephritis that can progress to renal abscess if left untreated. We examined the place of ALN in the spectrum of upper urinary tract infections. METHODS: : The medical records of all patients diagnosed with ALN by computed tomography (CT) were reviewed retrospectively in terms of their demographic characteristics, clinical presentations, and laboratory findings...

OBJECTIVES: To assess the consequences of renal ultrasonography (RUS) in the treatment of children younger than 5 years of age with a first febrile urinary tract infection. METHODS: We retrospectively reviewed the results of imaging studies, including RUS, computed tomography, and voiding cystourethrography in children with a first febrile urinary tract infection during a 2-year period. Children with known urologic anomalies, other underlying diseases, or simultaneous combined illnesses were excluded...

Acute focal bacterial nephritis (AFBN), formerly known as lobar nephronia, is a rare form of interstitial bacterial nephritis. Most often described in adults with diabetes, there is only limited knowledge of AFBN in children. Ultrasound shows circular hypoechogenic, hypoperfused parenchyma lesions, which may be misdiagnosed as a renal abscess or tumor. From 1984 to 2005, AFBN was diagnosed in 30 children at the University Hospital Münster and the General Hospital Celle, Germany. Data of 25 cases (14 girls, 11 boys) were available for retrospective evaluation...

BACKGROUND: Correct identification of acute lobar nephronia (ALN) is necessary to prevent progression to renal abscess. The goal of this retrospective study was to determine whether the sonographic finding of severe nephromegaly (i.e. renal length greater than mean + 3 sd) is a preselection criterion for computed tomographic (CT) scanning in diagnosing pediatric ALN among children with an acute upper urinary tract infection. DESIGN/METHODS: We evaluated a new imaging work-up scheme to detect pediatric ALN...

Focal bacterial nephritis or lobar nephronia represents an acute localized non-liquefactive infection of the kidney caused by bacterial infection. This is an uncommon form of pyelonephritis that can affect both adults and children. Imaging techniques, particularly CT scan, are necessary for diagnosis and to distinguish it from other conditions (abscess or renal masses) that require a different treatment. The authors describe a case of acute lobar nephronia in a 24-year-old man.

OBJECTIVE: A case of lobar nephronia in a child is presented. METHODS: Herein we describe a case of acute lobar nephronia in a 10-year-old boy. The clinical, diagnostic and therapeutic aspects are discussed. RESULTS/CONCLUSIONS: Acute lobar nephronia or acute focal bacterial nephritis is an uncommon form of pyelonephritis that can affect both adults and children, although few cases have been reported in children. Imaging techniques are necessary for diagnosis and to distinguish it from other conditions, such as abscess or renal masses that require a different treatment...

OBJECTIVE: To review the presentation, methods of diagnosis, and incidence of concomitant urological abnormalities in children with acute focal bacterial nephritis (AFBN, also known as lobar nephronia, a severe nonliquefactive infection involving one or more renal lobules). PATIENTS AND METHODS: Sixteen children (age range 6 months to 9 years) diagnosed with AFBN over a 5-year period were retrospectively reviewed. Their age, gender, presenting symptoms, presence of urinary tract abnormalities, radiological imaging and treatment were assessed...

We report 13 patients with 16 episodes of acute lobar nephronia diagnosed in a prospective study that was conducted among 210 hospitalized children with urinary tract infection. In 30 episodes of urinary tract infection, a hypoechogenic or hyperechogenic lesion was found. Twenty patients underwent computed tomography, and in 16 of them acute lobar nephronia was diagnosed. Evolution to renal abscess occurred in 25%. Prolonged intravenous antibiotic treatment was sufficient in all cases.

The clinical records and computerized tomography (CT) scans of 14 patients who presented with pyelonephritis to the Children's Hospital of Buffalo between 1976-1985 have been reviewed. The CT findings were as follows: multifocal pyelonephritis (6), lobar nephronia (6), focal pyelonephritis (2). All patients were treated with intravenous antibiotics, and none was surgically drained. Significant underlying diseases were present in 8 patients: diabetes (6), von Gierke disease (1), hepatorenal syndrome (1). The diabetic children tended to have focal disease...

We present three cases of acute lobar nephronia or acute focal bacterial nephritis on paediatric patients. Both radiological and echographic pictures are described, emphasizing those aspects which, together with a clinical symptomatology, allow a differential diagnose with abscess and neoplasias renally settled. We think that, among those patients suffering from pyelonephritis, an early practice of renal echography followed by further controls, allow an early detection of lobar nephronia cases and assessing a response to the treatment...
