A 60-year-old man with atherosclerotic disease experienced acute renal failure due to a retroperitoneal mass causing ureteral obstruction. Treatment involved ureteral stenting, surgery, and immunosuppressive therapy for retroperitoneal fibrosis.
Area of Science:
- Nephrology
- Cardiology
- Urology
Background:
- A 60-year-old male with established atherosclerotic disease presented with symptoms of acute renal failure.
- Imaging revealed a significant retroperitoneal mass causing bilateral ureteral obstruction.
Observation:
- The patient underwent a comprehensive diagnostic workup including physical examination, laboratory analyses, and advanced imaging such as CT and MRI.
- A renal ultrasound and mass biopsy were crucial in identifying the underlying cause.
Findings:
- The diagnosis was retroperitoneal fibrosis, a rare condition characterized by inflammation and fibrosis in the retroperitoneum.
- Management strategies included ureteral stenting, laparoscopic ureterolysis to relieve obstruction, and immunosuppressive therapy.
Implications:
- This case highlights the importance of considering retroperitoneal fibrosis in patients with unexplained renal failure and obstructive uropathy.
- Successful management involves a multidisciplinary approach combining interventional procedures and pharmacotherapy to prevent further renal damage.

Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
