Metallic ureteral stents
Patients with malignant ureteric obstruction and poor life expectancy usually require placement of ureteral stents to relieve the urinary obstruction and as a palliative measure to reduce pain and avoid major operation.
Metallic ureteric stents have recently been developed to try and offer better relief of obstruction than polymeric (polyurethane) stents due to:
- better maintaining ureteral patency in malignancy when conventional polyurethane stents are usually occluded.
- increased intervals between changes.
- less liable to infection, sepsis and bleeding as in nephrostomy tubes.
- less irritation of the lower urinary tract then JJ catheter.
Example of the metallic stent: Memokath stent which has expanded top to anchor it within the ureter.
