Percutaneous nephrostomy and antegrade ureteral stent insertion
Urology
|December 1, 1982
Summary
Percutaneous nephrostomy is a highly successful procedure for placing ureteral stents, even in cases of complete obstruction. This minimally invasive technique offers a high success rate with manageable complications for patients with urinary tract issues.
Area of Science:
- Urology
- Nephrology
- Interventional Radiology
Background:
- Percutaneous nephrostomy is a crucial intervention for managing urinary tract obstructions.
- Antegrade techniques are commonly employed for internal ureteral stent placement.
Purpose of the Study:
- To evaluate the success rate and complication profile of percutaneous nephrostomy for ureteral stent placement.
- To assess the efficacy of antegrade techniques in achieving successful stent insertion.
Main Methods:
- Sixty consecutive percutaneous nephrostomies were performed in 37 patients.
- Procedures included unilateral and bilateral interventions, with conversion to internal ureteral stents where feasible.
- Combined antegrade and retrograde techniques were utilized in complex cases.
Main Results:
- A 97% success rate was achieved in 60 attempted percutaneous nephrostomies.
- Successful negotiation and internal stent placement were accomplished in all cases of complete ureteral obstruction.
- One failure occurred due to a subcapsular hematoma, and one major complication involved renal artery injury.
Conclusions:
- Percutaneous nephrostomy is a highly effective method for ureteral stent placement, demonstrating a high success rate.
- The procedure is generally safe, with a low incidence of major complications, though potential risks exist.
- Minimally invasive antegrade techniques are valuable for treating complete ureteral obstructions.
