What we are working on

European Network of multidisciplinary research to Improve the Urinary Stents (ENIUS) is a network supported by COST. The indwelling of the urinary stents represents a very frequently used method within the urological practice, in order to ensure the drainage of the urine. Regardless of its composition, polymeric or metallic, it is associated with a high morbidity.

Success in this Action will contribute to improved healthy-quality of patients, reduction in health care costs, and increase the competitiveness of the European medical device industry. Our prime objective is to create a multidisciplinary group to identify the inherent problems in urinary stents and propose improvements for future urinary stents.
