Frequently Asked Questions
Q: Will my kidneys work the same as they did before the procedure?
A: Clinical trials using the Symplicity renal denervation system have demonstrated normal renal function with no kidney-related complications from the procedure. Successful kidney transplants have also shown that these renal nerves are not necessary for normal kidney function. In fact, deactivating them may cause a reduction in blood pressure and protect the heart, kidneys and blood vessels from further damage caused by hypertension.
Q: Will the procedure hurt?
A: Although you will be awake for the entire procedure, you will feel minimal pain. The access site will be numbed using local anesthesia, and pain medications will be administered intravenously as needed. When the catheters are inserted, most patients feel only a slight pressure or a sensation of mild tugging, but because there are no nerve endings inside the arteries, patients being catheterised cannot feel the catheters moving through them.
Q: How will the doctor know that the catheter is correctly placed?
A: Using a technique called fluoroscopy, a contrast dye is injected through the catheter and flows into the renal arteries. Your doctor can view the dye on the X-ray machine, which is hooked up to a monitor, and can trace the movement of the devices through your arteries.
Q: Will anything be implanted into my body?
A: This procedure requires no implants.
Q: How long does the procedure last?
A: The entire procedure will take about 40–60 minutes.

Q: When can I resume my regular activities?
A: Your doctor will advise you. Many patients can return to work and follow their normal routines very shortly after the procedure.
Q: Can I stop my antihypertensive medicine after the procedure?
A: Your doctor will advise you about the possibility of lowering any of your medications or stopping them altogether. Be sure to discuss your medications with your doctor before stopping or changing your dosage on your own.
