The RDN procedure refers to Renal Denervation (RDN) — a minimally invasive treatment for high blood pressure (hypertension), especially in patients whose blood pressure remains high despite medications.
What is the RDN (Renal Denervation) Procedure?
Renal Denervation is a catheter-based, non-surgical procedure that targets the renal nerves — nerves located around the arteries that supply blood to the kidneys.
These nerves play a key role in controlling blood pressure. In some patients, they become overactive, causing the body to release more stress hormones and raise blood pressure.
The doctor inserts a thin catheter (tube) through a small puncture in the groin or wrist.
The catheter is guided into the renal arteries (arteries that go to the kidneys).
Using radiofrequency energy, ultrasound, or other methods, the device ablates (disrupts) the overactive renal nerves.
The catheter is removed — no surgical cuts or stitches are required.
Lowers blood pressure
Helps reduce systolic and diastolic blood pressure, even in patients who don’t respond well to medications.
✅ Reduces dependence on medications
Some patients may need fewer antihypertensive drugs after RDN.
✅ Improves long-term cardiovascular health
Lower blood pressure means reduced risk of heart attack, stroke, and kidney disease.
✅ Safe and minimally invasive
No major surgery, short recovery time, and usually same-day discharge.
✅ Continuous effect ( Durable results)
Works 24/7 ( always on effect) by reducing nerve overactivity, unlike medications that depend on daily doses.
👨⚕️ Who Can Benefit?
Patients with resistant hypertension (blood pressure not controlled even after 3+ medications).
Those who are intolerant ( have side effects) to BP medicines or forget doses frequently.
Patients at high cardiovascular risk where better BP control is essential
