Which imaging modality is most commonly used to diagnose pyelonephritis?
Computed tomography (CT), when performed before, immediately after, and at delayed intervals from contrast material injection, is the preferred modality for evaluating acute bacterial pyelonephritis.
What are the differential diagnosis of pyelonephritis?
Pyelonephritis can be differentiated from other diseases that cause lower urinary tract irritation symptoms, such as: dysuria, urgency, and frequency, in addition to urethral discharge. The differential list includes: urethritis, cystitis, cervicitis, vulvovaginitis, epididimitis, prostatitis, and syphilis.
What is Xanthogranulomatous pyelonephritis?
Xanthogranulomatous pyelonephritis (XPN) is an unusual variant of chronic pyelonephritis. Most cases occur in the setting of obstruction due to infected renal stones [1-6].
How do you assess pyelonephritis?
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 is chronic pyelonephritis diagnosed?
The diagnosis of chronic pyelonephritis is made on the basis of imaging studies such as ultrasound or CT scanning. Treatment options include prophylactic antibiotics, endoscopic injection of dextranomer hyaluronic acid, and antireflux surgery.
How do you diagnose pyelonephritis?
Urinalysis and urine culture confirm the diagnosis of acute pyelonephritis. The consensus definition of pyelonephritis established by the Infectious Diseases Society of America (IDSA) is a urine culture showing at least 10,000 colony-forming units (CFU) per mm3 and symptoms compatible with the diagnosis.
What is uncomplicated pyelonephritis?
Abstract. Acute uncomplicated pyelonephritis is a bacterial infection of the renal parenchyma, common in women. The bacterium responsible is usually Escherichia coli. Empirical antibiotic therapy should be initiated promptly to prevent serious complications.
What is acute pyelonephritis diagnosis and treatment?
Acute pyelonephritis is a common bacterial infection of the renal pelvis and kidney most often seen in young adult women. History and physical examination are the most useful tools for diagnosis. Most patients have fever, although it may be absent early in the illness.
What causes Xanthogranulomatous pyelonephritis?
Xanthogranulomatous pyelonephritis is a chronic inflammatory condition that is caused by pyogenic infection of the kidney, usually secondary to staghorn calculi (70% of cases), most commonly by Proteus or E. coli.
What is the medical definition of xanthogranulomatous pyelonephritis?
Chronic xanthogranulomatous pyelonephritis (XGP) represents a rare type of granulomatous inflammation characterized by unilateral enlargement of a kidney, hydronephrosis and replacement of renal parenchyma by cysts containing serosanguinous fluid, with resultant loss of normal renal function.
Which is a rare form of pyelonephritis?
Dr Bruno Di Muzio ◈ and A.Prof Frank Gaillard ◉ ◈ et al. Xanthogranulomatous pyelonephritis (XGP) is a rare form of chronic pyelonephritis and represents a chronic granulomatous disease resulting in a non-functioning kidney. Radiographic features are usually specific.
When to have a partial nephrectomy for XGP?
Partial nephrectomy was recommended by urologic surgery consult once patient completes antibiotic treatment for suspected osteomyelitis. XGP is an uncommon chronic granulomatous renal infection resulting in loss of renal function.
What are the symptoms of XGP in women?
XGP can be focal or diffuse. 2 There is no predilection for either kidney, with women being more commonly affected than men. There is highly variable clinical presentation of XGP with acute symptoms of urinary tract infection (dysuria, hematuria, fever, chills and flank pain) or chronic, nonspecific symptoms (weight loss, malaise and anorexia).
