Less Encrustation in Urinary Stents

The ARTORG Urogenital Engineering group and other members of the ENIUS consortium - the ‘European network of multidisciplinary research to improve urinary stents’ - from Germany, the Netherlands, Finland, the UK, France, Spain and Portugal have reviewed research into improving urinary stents, identifying future research lines to address encrustation in urinary implants. These include coating strategies, encrustation sensing systems, biodegradable metals, bacteriophages, non-pathogenic bacteria, peristalsis enhancers, electrical charges, ultrasound and more.

In modern urological practice, ureteral stents and catheters have become indispensable tools to treat a wide range of upper urinary tract conditions, such as kidney stones, tumors, strictures and infections. Over the past decades, many improvements have been made on designs and constitutive materials to improve stent efficacy. But they remain associated with several adverse effects that limit their value as tools for long-term urinary drainage: The most common are infections, encrustation, migration, and patient discomfort.

The ARTORG Urogenital Engineering group is specialized in developing innovative engineering approaches to diagnose and treat diseases of the urinary tract. With a strong focus in fluid mechanical modeling, it has developed a new testing platform for ureteral stents. Group head Francesco Clavica is part of the ENIUS initiative as expert in fluid mechanics, microfluidics and electrophysiology.
