Unlike any other ureteral stent.
The Tria™ Ureteral Stent’s quality-driven manufacturing process, combined with the unique PercuShield™ design, produces consistent inner and outer surfaces, minimizing irregularities of the stent and reducing the likelihood of salt adhesion.1,2
How it works
Urine calcium and magnesium salt deposits are contributing factors to stent complications such as encrustation. The cause and rate of encrustation is multifactorial and can include factors such as body chemistry and medical condition of the patient, stent in-dwell time, and surface material or properties of the stent.3-6
Why choose Tria Ureteral Stent?
Significant durometer changes
Designed to be stiffer during placement to navigate patient anatomy while softening by over 40% at body temperature, which may promote greater patient tolerability.1,7,8
Optimal coverage
Unlike an applied coating, the PercuShield technology is embedded into the stent to provide protection throughout the entire indwell.1,2
No known contraindications
Potentially treat more patients.

- Study methodology: Testing was performed by an independent third-party using the in-vitro BEST™ method to evaluate salt adhesion of the ureteral stents. A total of 30 samples from each ureteral stent family were tested in both a sterile Artificial Urine Model and a Bacterial Infection Model (n=15 in each model) for 2 weeks. Proteus mirabilis was used as the microbial challenge in the Bacterial Infection Model due to its known urease production and involvement in struvite formation.
