"In close cooperation with our clinical advisors and partners in industry we fight costs, illness and deaths caused by stent and catheter related emergencies and infection. We fight the progression of bacterial resistances caused by the wide use of antibiotics, silver particles and other biocide substances. We improve patients' quality of life and at the same time help to lower healthcare related costs."

Patients with indwelling urinary devices are often treated with antibiotic medication. However, the use of antibiotics has not proven to suppress encrustation and their wide use harbours the risk of promoting bacterial resistances.

To use coated stents and catheters is another approach. But also antibiotic, silver and other biocide coatings lead to resistances. Furthermore these coatings accumulate cell material of dead bacteria on the surface, and that makes them ineffective after a short period of time. The same is true for drug eluting coatings, as their drug reservoir only lasts for one or two days. All these approaches could not proof to be effective in clinical use.  

UroNova's unique patented technology protects stents and catheters from biofilm formation and encrustation, resulting in fewer blockages of the urine drainage and injuries during removal. And this is accomplished without using antibiotics, silver particles or any other biocide substance. Proven, millionfold in clinical every-day practice.

No drug elution takes place, so no systemic side effects are caused. The coating's effectiveness is not limited in time, as it is long-term stable. Biocompatibility is unparalleled.

Infection, encrustation and blockage of indwelling catheters, ureteral stents and nephrostomy tubes are significant medical and health-economic problems. Because of these problems
  • about 50% of patients with permanent urinary drainage devices present as emergency cases during their course of disease
  • 13000 patients die
  • up to 1.3 Billion Euro additional costs are produced per year in Western Europe and a similar amount in North America.
