What is the ultrasound appearance of pyelonephritis?
What is the ultrasound appearance of pyelonephritis?
In most patients with acute pyelonephritis, the kidney appears normal on US. On gray-scale sonography, there may be diffuse or focal enlargement of the kidney, sometimes with a mass-like appearance. The involved areas are usually hyperechoic (Figs. 3A, C) and may be wedge shaped or round.
How can you tell the difference between acute and chronic pyelonephritis?
Acute pyelonephritis is a sudden and severe kidney infection. It causes the kidneys to swell and may permanently damage them. Pyelonephritis can be life-threatening. When repeated or persistent attacks occur, the condition is called chronic pyelonephritis.
Can you see pyelonephritis on ultrasound?
Acute pyelonephritis and acute ureteral obstruction often present with similar clinical and urographic findings. Ultrasound, however, can easily detect the presence of obstruction as well as demonstrate characteristic findings suggestive of acute pyelonephritis, and thus allows differentiation.
What are the clinical features of pyelonephritis?
Pyelonephritis occurs as a complication of an ascending urinary tract infection which spreads from the bladder to the kidneys. Symptoms usually include fever, flank pain, nausea, vomiting, burning with urination, increased frequency, and urgency.
What is chronic pyelonephritis?
Chronic pyelonephritis is characterized by renal inflammation and scarring induced by recurrent or persistent renal infection, vesicoureteral reflux, or other causes of urinary tract obstruction.
What are urinalysis findings in pyelonephritis?
Clinical and Laboratory Findings in Patients with Acute Pyelonephritis
| Category | Findings |
|---|---|
| Laboratory tests | Urinalysis showing positive leukocyte esterase test, microscopic pyuria or hematuria, or white blood cell casts |
| Peripheral blood smear showing leukocytosis, with or without left shift |
What is the chronic pyelonephritis?
Can ultrasound detect chronic renal?
Ultrasonographic findings such as longitudinal length, echogenicity, parenchymal and cortical thickness can be affected by chronic kidney disease [19, 20]. The GFR and stage of the disease can be ascertained by the endogenous serum creatinine level [21].
Can ultrasound detect kidney infection?
Ultrasound can detect cysts, tumors, abscesses, obstructions, fluid collection, and infection within or around the kidneys. Calculi (stones) of the kidneys and ureters may be detected by ultrasound.
