The CVAC System
A new standard in kidney stone treatment
It is estimated that one in ten people will have a kidney stone at some point in their lives, and many find themselves in the emergency room when the stones become painful. Since you’re reading this, chances are, you’re part of that group.
Why stone removal matters
The goal isn’t simply breaking up kidney stones—it’s removing them. Even tiny stone fragments left behind after treatment can become the starting point for future kidney stones or lead to additional complications, including:
- Stone regrowth
- Repeat procedures
- Urinary blockage
- Infection
- Kidney injury
Learn more about the types of kidney stones along with signs, systems, causes and prevention.
Why Choose the CVAC System?
Unlike traditional laser lithotripsy that often leaves fragments behind to pass naturally, the CVAC System actively removes stone fragments during and after laser treatment.
Benefits include:
- No surgical incisions
- More complete stone removal
- Lower chance of needing additional procedures
- Reduced likelihood of passing painful stone fragments at home
- Outpatient procedure for most patients
- Greater peace of mind knowing less stone is left behind
How the CVAC System works
STEP 1:
Access the kidney
A tiny camera is guided through the natural urinary tract to locate your kidney stone.
STEP 2:
Break up the stone
A precision laser breaks the stone into small fragments.
STEP 3:
Vacuum out the fragments
The CVAC System continuously removes stone fragments and dust during and after laser treatment, helping achieve a cleaner kidney before the procedure is complete.
Benefits include:
Before treatment
Your physician will evaluate your kidney stones, review imaging, discuss your treatment options, and provide instructions to prepare for your procedure.
During the procedure
You’ll receive anesthesia or sedation while your physician treats the stone using laser technology and the CVAC System to remove stone fragments.
Recovery
Most patients return home the same day. If a temporary ureteral stent is placed, it will typically be removed during a follow-up visit. Imaging may also be performed to confirm stone clearance.
