How the CVAC System compares with URS for treating kidney stones

In this video, Thomas Chi, MD, MBA, discusses advantages to the CVAC System. Chi is a professor of urology, associate chair for Clinical Affairs, and the Kutzmann Endowed Professor in Clinical Urology at the University of California, San Francisco.

Could you provide more information on the long-term clinical outcomes, such as recurrence rates, complications, and patient satisfaction associated with the CVAC System?

For this particular first study, we didn't look at long-term outcomes, but in a second project that's being completed now, and in a couple of studies that have been performed using the CVAC device, people have looked at longer term outcomes. More recently, some unpublished data have demonstrated that at 1 year, one of the things that we saw that was a significant difference between patients who had the first-generation CVAC device and traditional ureteroscopy with basketing was that patients who underwent procedures that cleared stones using the CVAC suction device actually had fewer ER and unanticipated clinic and hospital visits compared with traditional ureteroscopy, and that held up at a year. So it does seem like while we may clear more stones with the CVAC, one of the big benefits with the CVAC device is that it keeps people out of the hospital more often than compared with traditional ureteroscopy.
