Overview

The UroLume^® Urethral Stent is used to relieve urinary obstructions secondary to recurrent bulbar urethral strictures (RBUS), benign prostatic hyperplasia (BPH) or detrusor external sphincter dyssynergia (DESD). In this section, we will cover its use as solution for treating RBUS.

Features
UroLume is a braided mesh cylinder made of high strength, impact grade, super alloy wire. It has the potential to expand to a diameter of 14 mm (42F) and is available in lengths of 1.5 cm, 2.0 cm, 2.5 cm and 3.0 cm.

The braided mesh is designed to expand radially, applying constant gentle pressure to hold open the sections of the urethra that obstruct the flow or urine. The open, diamond-shape cell design of the stent allows the stent to eventually become embedded in the urethra, thus minimizing the risk for encrustation and migration.

UroLume is provided preloaded in a sterile, disposable delivery instrument. The outer diameter of the tool is 22F along the shaft and 24F at the tapered tip. The delivery instrument provides:

Secure housing for the stent to allow for transurethral placement
Direct visualization of the stent and the urethra throughout the procedure
The ability for you to deploy the stent accurately within the urethra

Benefits
UroLume offers a number of benefits for your patients with recurrent bulbar urethral strictures (RBUS):

Minimally invasive procedure can be performed within 15 minutes under local anesthesia
11 years of clinical follow-up shows immediate and long-term flow improvement with significantly reduced re-treatment rates¹
Tissue ingrowth ensures anchorability of the stent and preventing most encrustation
