Overview
Ultrasonography is an effective non-invasive technique in the diagnosis of pyelonephritis. It is sometimes used as a replacement of cortical scintigraphy in the diagnosis of acute pyelonephritis in children.[1][2][3]
Ultrasound
The diagnosis of pyelonephritis using ultrasound may feature the following:[4]
- In case of recurrent urinary tract infections, it can help to rule out presence of anatomical defects like polycystic kidney disease.
- Emphysematous pyelonephritis: Ultrasound will present an enlarged kidney containing air filled regions within the renal parenchyma, with shadowing shown posterior to the defect; It might not be as helpful in detecting the depth of involvement and stones can also show posterior shadowing.
- Xanthogranulomatous pyelonephritis: Ultrasound shows the inflammatory mass, with central shadowing depicting renal calculi.
