Retroperitoneal fibrosis with normal intravenous urogram
Postgraduate Medical Journal
|February 1, 1985
Summary
Retroperitoneal fibrosis can rapidly cause renal failure within months. Early symptoms like back pain may not show abnormalities on intravenous urogram (IVU) scans.
Area of Science:
- Nephrology
- Urology
- Radiology
Background:
- Retroperitoneal fibrosis is a rare condition characterized by inflammation and fibrosis in the retroperitoneum.
- It can lead to ureteric obstruction and subsequent renal impairment.
- Early diagnosis is crucial for effective management.
Observation:
- A 58-year-old male presented with low back pain and malaise.
- Initial intravenous urogram (IVU) showed normal renal function.
- Within three months, repeat IVU revealed renal failure due to bilateral ureteric obstruction.
Findings:
- Primary retroperitoneal fibrosis was confirmed intraoperatively.
- The case highlights the potential for rapid progression of retroperitoneal fibrosis.
- Normal IVU findings in early stages can delay diagnosis.
Implications:
- Emphasizes the need for vigilant monitoring in patients with suspected retroperitoneal fibrosis.
- Suggests considering advanced imaging or alternative diagnostic methods if initial IVU is normal.
- Underscores the importance of recognizing the varied clinical presentations of retroperitoneal fibrosis.
