Stenostent® Ureteral Stents

Stenostent® is the comfortable way to treat stenosis. The 12 Fr reinforced stent is constructed of silicone which has demonstrated greater patient comfort compared to stents constructed of alternative materials1 and is approved for indwell up to 12 months. The coils of Stenostent taper to 8 Fr leaving minimal material within the bladder.

Stenostent is inserted over a guidewire like a traditional double-loop stent and is packaged with a steerable pusher for precise placement.
