Ureteral changes in polyarteritis nodosa as seen during excretory urography
The Journal of Urology
|December 1, 1976
Summary
Excretory urography can diagnose polyarteritis nodosa by revealing characteristic ureteral wall imprints or a "string of pearls" appearance. These findings are pathognomonic for this vasculitic disorder.
Area of Science:
- Nephrology
- Radiology
- Vascular Medicine
Background:
- Polyarteritis nodosa (PAN) is a systemic vasculitis affecting medium-sized arteries.
- Accurate and timely diagnosis of PAN is crucial for effective management and improved patient outcomes.
Observation:
- The excretory urogram, a conventional diagnostic imaging technique, may offer key insights into the diagnosis of PAN.
- Specific radiographic findings on the ureter can be highly indicative of the disease.
Findings:
- Pathognomonic signs of PAN on excretory urography include imprints on the ureteral wall.
- A nodular appearance of the ureter, resembling a string of pearls, is another characteristic finding suggestive of PAN.
Implications:
- These urographic findings can aid in the early and accurate diagnosis of polyarteritis nodosa.
- The presented cases highlight the diagnostic utility of excretory urography in identifying specific ureteral manifestations of PAN.
- Understanding these imaging patterns is essential for differential diagnosis in patients with suspected vasculitis.
