Summary
A Malecot nephrostomy catheter obstruction in a post-cystectomy patient was resolved by removing granulation tissue. This case highlights a rare complication of nephrostomy tube blockage.
Area of Science:
- Urology
- Nephrology
- Surgical Complications
Background:
- Radical cystectomy and bilateral nephrostomy are complex procedures.
- Nephrostomy tubes are essential for urinary drainage post-surgery.
- Catheter obstruction can lead to significant patient morbidity.
Observation:
- A patient presented with left nephrostomy catheter blockage 19 days post-operation.
- Imaging revealed catheter deformity suggesting an internal obstruction.
- Initial repositioning attempts were unsuccessful.
Findings:
- Surgical exploration identified granulation tissue bridging the Malecot flanges.
- The granulation tissue was surgically excised.
- The nephrostomy catheter was successfully exchanged after tissue removal.
Implications:
- Granulation tissue formation is a potential complication of Malecot nephrostomy tubes.
- Prompt diagnosis and surgical intervention are crucial for managing such obstructions.
- Understanding this complication can improve post-operative care for patients with nephrostomy tubes.
