Emphysematous pyelonephritis is a gas-producing, necrotizing infection involving the renal parenchyma and surrounding tissue that is associated with high mortality and morbidity. Common causative organisms include Escherichia coli and Klebsiella pneumoniae. While most patients are being managed conservatively these days, nephrectomy may be needed in severe cases.

Emphysematous pyelonephritis (EPN) is a severe necrotizing infection of the renal parenchyma. The clinical course of EPN can be severe and life-threatening if not recognized and treated promptly. Most of the information has been from case reports, a few large series have also been reported. Using an evidence-based approach, this review describes the pathogenesis, classification, complications, ...

Emphysematous pyelonephritis (EPN) is an acute necrotizing and suppurative infection of the kidney parenchyma. It is defined by the presence of gas within the kidney parenchyma and surrounding tissues. This rare condition is usually seen in diabetic or immunocompromised adults. In this paper, we report four cases of emphysematous pyelonephritis (including two diabetic patients) managed by broad...

Emphysematous pyelonephritis (EP) is a life threatening condition of acute necrotising renal parenchymal infection that encompasses a much wider spectrum of complicated urinary tract infections such as renal abscesses, emphysematous pyelitis, pyelonephritis, acute renal papillary necrosis, and sepsis. We report an unusual case of adenocarcinoma bladder in a middle aged nondiabetic patient, pres...

Emphysematous pyelitis (EP) is a subclass of a life-threatening necrotizing infection of the urinary system called emphysematous pyelonephritis (EPN). We report a case of an 81-year-old man with emphysematous pyelitis, which occurred after urinary tract instrumentation and resolved with conservative medical management. This case highlights the potential complications of urinary tract manipulati...

Although high mortality rates have been reported for emphysematous pyelonephritis (EP), information on emphysematous cystitis (EC), which is less common, is sparse. Here, we report one new case of severe EC and 136 cases of EC that occurred between 2007 and 2016, and review information about the characteristics, diagnosis, treatment and mortality of these patients, and the pathogens found in th...

Bacterial infection is the most common cause of pyelonephritis. Acute complicated pyelonephritis is an acute emergency and needs immediate treatment with intravenous antibiotics. Infection in acute pyelonephritis is usually due to ascending infection, or due to hematogenous infection. Chronic pyelonephritis is characterized by the presence of recurrent infections, usually due to structural and ...
