Antegrade ureteric stent
Updates to Article Attributes
Antegrade ureteric stents are performed under fluroscopicfluoroscopic guidance, typically by an interventional radiologist or urologist. It is performed via percutaneous access access from the kidney. It is usually performed using the access from a prior percutaneous nephrostomy, a so called-called 2 step-step procedure, although may be performed de-novo.
The vast majority of ureteric stents placed are polyurethane in composition and require to be changedchanging if left for longer than 3 months. Metallic stents, composed of coiled spirals, have been available in recent years for those with malignant ureteric obstruction. These may be left for 12 months or more since they are corrosion resistant. Metallic stents demonstrate a reduction in the rate of tumour regrowth compared with conventional stents.1
Most practitioners leave a 'covering nephrostomy' in place for 24-48 hours after stent insertion. ThisThis may be clamped to ensure good output from the stent (via the bladder), before the nephrostomy is removed and access is lost.
