Summary
Diagnosing acute pyelonephritis relies on clinical and bacterial data, but imaging is crucial for identifying urinary tract obstructions. Ultrasonography with radiography or urography is preferred, while CT scans aid in complex cases.
Area of Science:
- Nephrology
- Radiology
- Infectious Diseases
Background:
- Acute pyelonephritis diagnosis traditionally relies on clinical and bacteriological data.
- Imaging plays a vital role in identifying potential urinary tract obstructions contributing to pyelonephritis.
Purpose of the Study:
- To evaluate the role of various imaging modalities in the diagnosis and management of acute pyelonephritis.
- To highlight the diagnostic and prognostic value of imaging in specific patient groups.
Main Methods:
- Review of diagnostic approaches for acute pyelonephritis.
- Emphasis on ultrasonography, plain abdominal radiography, intravenous urography, and computerized tomography (CT).
Main Results:
- Ultrasonography combined with plain abdominal radiography or intravenous urography is the primary imaging choice.
- Computerized tomography offers invaluable diagnostic and prognostic information in atypical cases, high-risk patients, or those resistant to treatment.
Conclusions:
- While clinical and bacteriological data are primary, imaging is essential for excluding obstructive causes of acute pyelonephritis.
- Advanced imaging like CT is critical for complex and treatment-resistant cases, aiding both diagnosis and prognosis.
