Summary
Fluoroscopically guided percutaneous removal of malfunctioning ureteral stents is a highly successful procedure. Utilizing appropriate techniques and instruments ensures effective extraction of ureteral stents and fragments.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Interventional Radiology
Background:
- Dysfunctional ureteral stents can lead to patient discomfort and complications.
- Percutaneous removal offers an alternative to traditional methods for difficult stent cases.
Purpose of the Study:
- To detail the experience with fluoroscopically guided percutaneous removal of problematic ureteral stents.
- To discuss the techniques and instruments employed in this procedure.
Main Methods:
- A retrospective review of 20 patients undergoing percutaneous stent extraction over 6 years.
- Procedures involved rigid forceps, flexible forceps, or snares, with a 12-F sheath.
- Extractions were performed as one-stage or two-stage procedures.
Main Results:
- Successful removal in 17 out of 20 procedures (85%).
- Rigid forceps were the most common instrument for successful extraction.
- Reasons for failure included intervening mucosa or clotted blood; no major complications occurred.
Conclusions:
- Fluoroscopically guided percutaneous stent removal is a safe and effective technique.
- Success is contingent upon the appropriate selection of instruments and procedural technique.
