We analyzed the within-household evolution of two household-associated Escherichia coli strains from pandemic clonal group ST131-H30, using isolates recovered from five individuals within two families, each of which had a distinct strain. Family 1's strain was represented by a urine isolate from the index patient (older sister) with recurrent cystitis, and a blood isolate from her younger sister with fatal urosepsis. Family 2's strain was represented by a urine isolate from the index patient (father) with pyelonephritis and renal abscesses, blood and kidney drainage isolates from the daughter with emphysematous pyelonephritis, and urine and fecal isolates from the mother with cystitis...

Emphysematous pyelonephritis is an acute infection of the renal parenchyma and perinephric tissues caused by gas-forming microorganisms, resulting in the radiographic presence of gas in the kidney, collecting system, and surrounding spaces. Here we present a case of severe emphysematous pyelonephritis in the setting of Klebsiella urosepsis. Surgical exploration of the flank revealed infectious disintegration of the renal parenchyma into a large phlegmon. The post-operative course was complicated by renal artery pseudoaneurysm and cutaneous fistualization of a perinephric fluid collection...

Emphysematous pyelonephritis (EPN) is a rare life-threatening complication of a properly functioning renal allograft leading to potential graft loss and hemodialysis. Currently, no clear management guidelines exist in these clinically challenging immunosuppressed renal transplant recipients. We report a case of a 62-year-old woman who presented with class 4 EPN and was managed with intravenous antibiotics and nephrectomy at our medical center.

BACKGROUND: The objective of this study was to examine the usefulness of blood cultures and radiologic imaging studies for developing therapeutic strategies in community-acquired acute pyelonephritis (CA-APN) patients. MATERIALS AND METHODS: We prospectively collected the clinical data of CA-APN patients who visited 11 hospitals from March 2010 to February 2011. RESULTS: Positive urine and blood cultures were obtained in 69.3% (568/820) and 42...

The authors report an interesting coincidental unearthing by 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) of a potentially serious medical condition of emphysematous pyelonephritis in a case of nasopharyngeal carcinoma. The management by conservative ureteric stenting and antibiotics was done with gratifying clinical outcome.

Oligella urethralis (O. urethralis) is an organism that rarely causes infections in humans. We report the case of a 90-year-old bedridden woman with progressive dementia who was placed in a long-term-care facility. She was admitted to our hospital due to fever and unconsciousness with pyuria. The abdominal computed tomography showed left pneumatosis and urinary stone. Fluoroquinolones-resistant O. urethralis, which was identified by the Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) and the 16S rRNA gene sequencing, was isolated form the blood and urine cultures at admission...

Emphysematous pyelonephritis is a rare infection characterized by necrosis and gas accumulation in the renal parenchyma, adjacent tissues, and/or urinary collecting system. This entity is rarely reported in transplanted kidneys. Computed tomography imaging is necessary for diagnosis and risk classification. The authors described the case of a 58-year-old man who underwent a kidney transplant and presented sepsis from a urinary tract infection. An abdominal tomography showed some characteristics of emphysematous pyelonephritis associated with an abscess...

INTRODUCTION: Emphysematous pyelonephritis (EPN) is a rare and severe, necrotizing infection of the kidney. Diagnosis should be precocious based on computed tomography (CT). Its management remains controversial and its treatment is currently increasingly conservative. The aim of this paper is to discuss the conservative treatment of this disease through our experience in 21 patients. MATERIAL AND METHODS: A retrospective analysis including 21 patients managed conservatively for an emphysematous pyelonephritis in our department from January 2010 to April 2015...

BACKGROUND: Emphysematous pyelonephritis is a severe infection of the kidney associated with formation of gas in the renal parenchyma and/or collecting system. The purpose of this study was to evaluate outcomes of patients with emphysematous pyelonephritis in a contemporary cohort and to evaluate the impact of urolithiasis on disease severity. METHODS: A search of all imaging reports at University of California San Francisco (UCSF) for the term "emphysematous pyelonephritis" was undertaken from 2003-2014...

A 40-year-old woman withuntreated type II diabetes mellitus was discovered withcardiopulmonary arrest in her room. On admission, she had ventricular fibrillation. After cardiopulmonary resuscitation, her own pulse restarted. The plasma glucose was 722 mg/dl and venous PH was 6.704. Abdominal computed tomography revealed gas within the parenchyma of the left kidney. We diagnosed her with emphysematous pyelonephritis and conducted emergency nephrectomy. Urinary and blood cultures were positive for Escherichia coli...

Emphysematous pyelonephritis is a severe necrotizing infection of the kidneys characterized by gas formation within the parenchyma, the collecting system or the perinephric tissue. To our knowledge, there have only been 4 cases of this condition reported in children. We report 2 additional cases in children managed at Chris Hani Baragwanath Academic Hospital, Johannesburg, South Africa.

BACKGROUND: Staghorn calculi are well-established risk factors for recurrent urinary tract infections (UTIs) and subsequent renal deterioration. Less commonly, long-term urothelial irritation from a calculus may also pose a risk of malignant transformation. CASE PRESENTATION: A 77-year-old male with multiple medical comorbidities presented with a chronic right renal pelvic staghorn calculus and findings concerning for emphysematous pyelonephritis. He was subsequently taken to the operating room for a planned laparoscopic right nephrectomy...

BACKGROUND: Emphysematous pyelonephritis (EPN) is a severe infection of the urinary tract, caused by gas accumulation within the collecting system, the renal parenchyma, and/or the perirenal tissue. The cause of this infection is not known at all; however, it has been suggested that it is produced by the glucose fermentation provoked by enterobacteriaceae or anaerobic organisms. Our objective was to evaluate the predictors of morbidity and mortality in patients diagnosed with EPN. METHODS: It was carried out a historical cohort study of patients diagnosed with EPN in our hospital from March 2005 to December 2014...

CONTEXT: Emphysematous pyelonephritis (EPN) is an acute necrotizing inflammation of renal parenchyma and peri-nephric tissue characterized by gas formation. In this study, we evaluated the outcome of EPN cases by medical management with or without renal decompression. MATERIALS AND METHODS: We have observed prospectively 15 cases of EPN admitted in our institute in respect to age, sex, mode of presentation, presence of comorbidity, laboratory profile, urine-analysis, and outcome after medical management and drainage procedures...

BACKGROUND: Emphysematous pyelonephritis (EPN) is a necrotizing infection which results in gas within the renal parenchyma, collecting system, or perinephric tissue. A majority of cases occur in patients with diabetes mellitus (DM). In EPN, early aggressive medical treatment may avoid nephrectomy. AIMS: The aim of this study was to analyze the characteristics of patients with EPN with respect to patient demographics, clinical presentation, diagnostic investigations, microbiological findings, treatment modality and outcome, and the influence of prognostic factors on the outcome...
