Surface Acoustic Wave Treatment in Urology

There are several applications for surface acoustic wave treatment in urology. Various publications have indicated that it is an effective treatment for the prevention of microbial biofilm formation, for enhancing neutrophil killing of bacteria, and for lowering susceptibility to UTIs from the use of long-term indwelling catheters.

How Does the Technology Work?

Acoustic energy waves are produced from electrically activated piezo elements. These waves are distributed throughout the medical device’s entire length (catheters, implants, endotracheal devices, etc.). These waves inhibit potential bacteria from binding to the device’s surface. This, in turn, keeps the surface more sterile and reduces biofilm buildup.

Prevention of CAUTI (Catheter-Associated Urinary Tract Infections)

It is estimated 40 percent of HAIs (hospital-acquired infections) are urinary tract infections. Of that 40 percent, 75 percent are associated with the use of urinary catheters. Furthermore, 30 to 40 percent of those UTIs will develop into gram negative septicemia, which could in turn into septic shock. The longer the catheter remains in the patient, the higher the incidence rate of acquiring microbial biofilm formation. Surface acoustic wave urology treatment has been shown to be highly effective in preventing adhesion of microbes on the catheter’s surface, thus greatly reducing the possibility of infection.

Surface Acoustic Waves Enhance Neutrophil Killing of Bacteria

The leading cause of infections from the use of indwelling catheters and prosthetic devices is the formation of biofilms caused by the Staphylococcus epidermidis bacteria. These bacteria cause biofilms to form among several devices, including artificial joints, pacemakers, contact lenses, heart valve replacements, and other surgical implants. Typical eradication of bacteria from infection is fought off by white blood cells, such as neutrophils and macrophages. Unfortunately, these white blood cells have shown to be ineffective at breaking through the biofilm, most likely due to an exopolysaccharide “slime” matrix formed by the bacteria. With the use of SAW (surface acoustic waves) technology, this treatment promotes the entry of neutrophils into the biofilm structure, significantly increasing the bacterial killing.
