Summary
Percutaneous antegrade ureteric stenting is effective for relieving ureteric obstruction in patients with malignant disease when retrograde stenting is not feasible. This minimally invasive procedure offers a successful alternative for managing advanced renal failure caused by ureteric blockage.
Area of Science:
- Urology
- Nephrology
- Interventional Radiology
Background:
- Progressive ureteric obstruction can lead to fatal renal failure (uraemia).
- Retrograde ureteric stenting is often challenging or impossible in patients with malignant disease.
- Urgent management is critical for patients with solitary kidneys or bilateral obstruction.
Purpose of the Study:
- To evaluate the efficacy and success rate of percutaneous antegrade ureteric stent placement.
- To assess the feasibility of this technique in patients with malignant disease where retrograde stenting failed or was contraindicated.
- To provide a minimally invasive treatment option for severe ureteric obstruction.
Main Methods:
- Retrospective analysis of 37 percutaneous antegrade ureteric stent placements.
- Procedures performed on 25 selected patients with a history of malignant disease.
- Focus on cases where retrograde stenting was impossible or difficult.
Main Results:
- A high success rate of 34 out of 37 attempts (91.9%) was achieved.
- The procedure was successfully performed in 25 selected patients.
- Demonstrated feasibility in complex cases of malignant ureteric obstruction.
Conclusions:
- Percutaneous antegrade ureteric stenting is a safe and effective alternative.
- It offers a viable solution for managing ureteric obstruction in oncological patients.
- This technique can prevent renal failure and improve patient outcomes.
