Round (RPS) Posterior Urethral Stent

Allium RPS stent is a temporary implant designed for transurethral placement in the male posterior urinary tract diagnosed with a stenotic bladder neck due to stenotic posterior urethra, Bladder Outlet Obstruction (BOO), urethro-vesical, or urethro-neovesical anastomotic stenosis.

Stent consists of super elastic spiral coated with copolymer. After insertion into the urinary tract with the help of a delivery system, stent is released to allow self-expansion. It is designed to stay in place up to 3 years.

Key Benefits

  • With its special design, it provides wide lumen opening and reduces tissue discomfort.
  • It eliminates the possibility of repetitive intervention, thanks to its long-term stay. Therefore, it provides comfort to the patient for a long time and reduces the cost.
  • Thanks to its unique polymeric coating, it prevents tissue in-growth; reduces stone formation, crusting and calcification.
  • Thanks to the high flexibility of the stent, it provides minimal irritation and maximum patient comfort.
  • Thanks to the radial force in the stent body, excellent stent fixation is achieved and it adapts to the patient’s anatomy.
  • Thanks to the radiopaque markings on the stent tips, it is easily placed and positioned correctly.
  • Special anchors placed in the stent body with a trans-sphincteric wire protect the sphincter’s function while reducing the possibility of stent migration.

Sphincter Friendly Section

It prevents the formation of incontinence by preventing the pressure on the sphincter with its dynamic sphincter section.

Unique Coating

Thanks to its fully covered,  non-porous polymeric coatin, it prevents tissue in-growth, reduces stone formation, crusting and calcification.

Easy Removal

The stent can be removed from the urethra with the help of foreign body forceps without traumatizing the urethra.

High Flexibility 

It provides minimal irritation and patient comfort thanks to its flexible body that is resistant to urethral pressure.

Easy Placement

Thanks to its advanced delivery system, it is easily placed visually, endoscopically and/or under fluoroscopy.

Long Term Indwelling
It is intended for a long indwelling period and it can eliminate the need of recurrent procedures.
