How is emphysematous pyelonephritis diagnosed?
Emphysematous pyelonephritis is a radiological diagnosis made by CT scan, abdominal radiograph, or renal ultrasound. CT scan is considered the definitive modality because of its ability to fully characterize the extent and position of gas within the kidney and collecting system and identify any tissue destruction.

How is emphysematous pyelonephritis treated?
Nephrectomy is the treatment of choice in most patients with emphysematous pyelonephritis (EPN). However, patients with EPN are extremely ill and need resuscitative measures in the intensive care unit. Surgical intervention should be performed only after stabilization of the cardiorespiratory status.
What is the initial therapy for emphysematous pyelonephritis?
Third-generation cephalosporins are recommended as initial treatment of EPN. In patients with histories of prior hospitalization and antibiotic use and in those needing emergency hemodialysis or developing DIC, carbapenem is the empiric antibiotic of choice.
What does emphysematous pyelonephritis mean?
EMPHYSEMATOUS pyelonephritis (EPN) has been defined as a necrotizing infection of the renal parenchyma and its surrounding areas that results in the presence of gas in the renal parenchyma, collecting system, or perinephric tissue.
What causes emphysematous pyelonephritis?
The main bacteria causing emphysematous pyelonephritis are the classical germs of urinary tract infection. The most common is Escherichia coli. Other bacteria include Klebsiella pneumoniae, Proteus mirabilis and Pseudomonas aeruginosa [4-7].
How is emphysematous cystitis treated?
Endovenous antibiotics, such as flouroquinolones, penicillin with beta-lactamase inhibitors and third generation cefalosporines, are some of the appropriate treatments. Antifungal agents may be used in cases of a fungal infection. The agent in our case was E. coli, which was sensitive to piperacillin-tazobactam.
How is pyelonephritis diagnosed by imaging?
Computed tomography (CT) of the abdomen and pelvis with contrast is considered the study of choice in complicated acute pyelonephritis. CT can detect focal parenchymal abnormalities, emphysematous changes, and anatomic anomalies, and can also define the extent of disease.
How is pyelonephritis diagnosed?
Diagnosis and Tests Two common laboratory tests are performed to diagnose kidney infections (pyelonephritis). A urine sample is examined under a microscope to determine if white and/or red blood cells are present. The urine is also sent to the lab to see if bacteria grow in a urine culture.
How does diabetes cause emphysematous pyelonephritis?
Emphysematous pyelonephritis (EPN) is the necrotizing infection of renal parenchyma with the presence of gas in the renal parenchyma, collecting system or perinephric tissue. EPN is an uncommon life-threatening condition, precipitated mainly by poorly controlled blood sugars and urinary tract obstruction.
What is Emphysematous?
Emphysema is a lung condition that causes shortness of breath. In people with emphysema, the air sacs in the lungs (alveoli) are damaged. Over time, the inner walls of the air sacs weaken and rupture — creating larger air spaces instead of many small ones.
How do you test for emphysematous cystitis?
CT scan is the gold standard in diagnosing a case of emphysematous cystitis but X-ray findings should not be overlooked. Prompt diagnosis with early bladder drainage and broad-spectrum antibiotics is mandatory to avoid morbidity and mortality.
Can emphysematous cystitis be cured?
Antibiotics are proven to cure Emphysematous cystitis over time and reduce the amount of gas inside the bladder wall. Prognosis is poor if antibiotics are not used to treat the patient. Additional treatment consists of urinary drainage and good control of blood glucose.
What type of CT is used for pyelonephritis?
What does pyelonephritis look like on CT scan?
Imaging findings in emphysematous pyelonephritis (EPN) include parenchymal enlargement and destruction (irregular shape of kidney with focal necrotic areas) and fluid collections with air-fluid levels.
What is the prognosis of emphysematous pyelonephritis (EPN)?
Emphysematous pyelonephritis (EPN) is a rare, life-threatening necrotizing renal parenchymal infection. Traditional management of EPN with nephrectomy had a mortality of 40-50%. The purpose of this case series was to assess the management, biochemical factors, and outcome of EPN patients. Methods:
What is the history of emphysematous pyelonephritis?
INTRODUCTION Emphysematous pyelonephritis (EPN) is an acute severe necrotizing infection resulting in the presence of gas in the renal parenchyma, collecting system or perinephric tissue.1The first reported case was in 1898 by Kelly and McCullum1but the prevalence in Western countries remains low at 1-2 cases annually.
Diagnosis: Emphysematous pyelonephritis: class 2 or type 1. Escherichia coli was isolated from urine obtained by endoscopic drainage. Management: Endoscopic drainage of pus and simple nephrectomy.
How is acute pyelonephritis (EPN) graded on CT?
Seven cases presented with acute pyelonephritis, seven cases with urosepsis, and the remaining eight patients with multi-organ dysfunction. CT grading of EPN was class IV in three, class III in four, class II in 14, and class I in one. All were initially managed medically with parenteral antibiotics.
