From patients undergoing Radical Prostatectomy for localized prostate cancer, up to 18-20% develop urethro-vesical anastomotic stenosis. Similar stenosis may develop after radical cysto-prostatectomy for bladder cancer. Bladder-neck stenosis can also develop after TURP or thermotherapy for BPH; posterior urethral stricture may develop after prostate brachytherapy. There are no adequate and satisfactory solutions for these strictures which are managed mainly by palliative dilations or recurring resections. A Reconstructive surgery of these strictures is extremely difficult and is considered an invasive procedure.
The Allium RPS – Round Posterior Stent is a minimally invasive reversible solution for a difficult problem.
The Allium Round Posterior Urethral Stent is a temporary stent implant comprised of a super-elastic structure, which fully covered and embedded in a co-polymer. By inserting the Stent into the posterior urethra of these patient and immediate opening of the occlusion is achieved. During the indwelling period the stent acts holds the lumen open, prevents ingrowth and provides a good passage of urine flow.
As with all the other Allium stents the following benefits are also applicable to the RPS stent implant:
- Long dwelling time of up to 3 years
- An Easy Fluoroscopic insertion and positioning
- Anatomical design
- Large lumen
- Excellent patient comfort
- Excellent voiding control at the presence of a functioning external sphincter
- No tissue in-growth
- Easily removable
- Delivery system – the RPS is mounted on a Rigid deployment system of 24Fr
- Stent sizes available: the RPS is 30mm or 40 mm long and has a caliber of 45 Fr
