Summary
A rare ureterocolonic fistula developed in a patient with a nonfunctioning ureter after nephrectomy. Diverticular disease of the colon was the cause, highlighting the importance of clinical suspicion and imaging for diagnosis.
Area of Science:
- Urology
- Gastroenterology
- Surgical Pathology
Background:
- A 68-year-old patient with a history of nephrectomy presented with chronic abdominal pain.
- The patient had undergone a previous nephrectomy due to xanthogranulomatous pyelonephritis.
Observation:
- Radiological imaging revealed a pneumogram pattern in the ureteral stump and a pelvic mass.
- Surgical exploration was performed to investigate a suspected uretero-intestinal fistula.
Findings:
- The patient was diagnosed with a uretero-sigmoid fistula.
- The fistula was found to be secondary to acute sigmoid diverticulitis.
- Anatomopathological examination confirmed the diagnosis.
Implications:
- Uretero-intestinal fistulas can have subtle clinical presentations.
- Early diagnosis relies on a combination of clinical suspicion and appropriate radiological assessment.
- This case underscores the importance of considering diverticular disease as a cause of uretero-intestinal fistulas, especially in patients with prior abdominal surgery.
