Genotypic Analysis of E. coli Strains Isolated from Patients with Cystitis and Pyelonephritis
2012
BACKGROUND: Urinary tract infection is the most common health problem affecting millions of people each year, mainly caused by a large genetically heterogeneous group of Escherichia coli called uropathogenic E. coli This study investigates the genotypic analysis of E. coli strains isolated from patients with cystitis and pyelonephritis. METHODS: During 2008-2009, 90 E. coli strains were analyzed, consisting of 48 isolates causing pyelonephritis in children and 42 isolates causing cystitis. Having identified the strains by standard methods, they were subtyped by pulsed field gel electrophoresis (PFGE) and their corresponding patterns were compared using dendrogram. RESULTS: Sixty five PFGE p…
Urinary tract infections in children: EAU/ESPU guidelines.
2015
Context: In 30% of children with urinary tract anomalies, urinary tract infection (UTI) can be the first sign. Failure to identify patients at risk can result in damage to the upper urinary tract.Objective: To provide recommendations for the diagnosis, treatment, and imaging of children presenting with UTI.Evidence acquisition: The recommendations were developed after a review of the literature and a search of PubMed and Embase. A consensus decision was adopted when evidence was low.Evidence synthesis: UTIs are classified according to site, episode, symptoms, and complicating factors. For acute treatment, site and severity are the most important. Urine sampling by suprapubic aspiration or c…
Acute human pyelonephritis: Leukocytic infiltration of tubules and localization of bacteria
1988
The fine structural details of how leukocytes appear in the lumen of tubules and the localization of bacteria in the tubulo-interstitial space were studied by light and electronmicroscopy in renal cortical biopsy specimens from three patients with acute pyelonephritis. The cells of interstitial infiltrates infiltrated and sometimes disrupted the cortical collecting tubules preferentially, while inflammatory infiltration of the proximal and distal convoluted tubules occurred more rarely. Since the emigration of tubular wall-localized individual leukocytes into the lumen was not observed even in long series of thin sections, focal inflammatory disruption of the uriniferous ducts was considere…
UN ERRORE DIAGNOSTICO IN CHIRURGIA PEDIATRICA: La pielonefrite grantogranulomatosa ed il Tumore di Wilms
1993
The Authors report a case of Xanthogranulomatous Pyelonephritis characterized by a torpid course and clinical presentation of renal mass.
Ureterosciatic Hernia A Rare Cause of Pyonephrosis
1989
A female patient presented as an emergency case with pyonephrosis and septicemia as a result of ureterosciatic hernia. Septicemia was treated successfully by immediate percutaneous nephrostomy tubing. After complete disappearance of symptoms, the hernia was closed operatively. Topographic anatomy of ureterosciatic hernia is presented.
CT imaging of acute and chronic pyelonephritis: a practical guide for emergency radiologists
2020
Contrast-enhanced CT is not routinely indicated in uncomplicated urinary infections, but it may be necessary in patients with specific risk factors (i.e., diabetes, immunocompromised patients, history of stones, or prior renal surgery) or in patients not responding to antibiotics and in detecting complications of pyelonephritis. CT is the gold standard for imaging assessment of pyelonephritis severity. Imaging appearance of acute pyelonephritis, including focal (i.e., wedge-shaped zones of decreased attenuation or hypodense mass) and diffuse (i.e., global enlargement, poor parenchymal enhancement, lack of excretion of contrast, fat stranding) forms, needs to be differentiated from renal inf…
