Exclusion Criteria:
- Current treatment with corticosteroids, nonsteroidal antiinflammatory drugs, or immunosuppressive drugs.
- Connective-tissue disease.
- Obstructive uropathy.
- Congestive heart failure (New York Heart Association class III or IV).
- Subject has significant renovascular abnormalities (a history of prior renal artery intervention, including balloon angioplasty or stenting; double renal artery on one side, distortion, and extension ), measured by abdominal ultrasound or renal angiograms.
- Subject has a history of myocardial infarction, unstable angina, cerebrovascular accident or alimentary tract hemorrhage in the previous 3 months.

Aktiver Komparator: RSD+Medicine
The investigators will recruit 50 randomised CKD patients who meet the inclusion criteria.
First undergo renal artery angiography procedure to confirm anatomy.
If renal artery meet the inclusion criteria, give the renal sympathetic denervation.
At the same time, we will use optimal medication to protect renal function.
Then we will conduct a clinic follow-up and a telephone follow-up e(Total 36 months).
|
Contrast renal angiography(iodixanol) was performed to localize and assess the renal arteries for accessibility and appropriateness for RSD.
Once the anatomy was deemed acceptable, the internally irrigated radiofrequency ablation catheter(Celsius Thermocool,Biosense Webster, Diamond Bar, California) was introduced into each renal artery.
then was maneuvered within the renal artery to allow energy delivery in a circumferential, longitudinally staggered manner to minimize the chance of renal artery stenosis.
About six to nine ablations at 10 W for 1 min each were performed in both renal arteries.
During ablation, the catheter system monitored tip temperature and impedance, altering radiofrequency energy delivery in response to a predetermined algorithm.

Placebo-Komparator: Medicine
The investigators aslo will recruit 50 randomised CKD patients who meet the inclusion criteria.
There are no significant differences in age, gender, race, past medical history,personal history and so on between the two groups.
In this group we will use optimal medication just like the RSD+Medicine group.
Third we will conduct a clinic and a telephone follow-up(Total 36 months).
|
Angiotensin converting enzyme inhibitors, angiotensin receptor antagonist, calcium antagonists, diuretic, beta adrenoceptor blocking agent, statins, platelet aggregation inhibitor, anticoagulants and so on.

Urinary protein excretion and renal function
Zeitfenster: 36 months
|
To evaluation of urinary protein excretion and renal function over time, by the reciprocal of the serum and urinary creatinine level, creatinine clearance and the glomerular filtration rate.
|
36 months
|
|
Blood pressure
Zeitfenster: 36 months
|
To study the effect of renal sympathetic denervation on blood pressure in patients with hypertension, which can be measured by ambulatory blood pressure and home blood pressure monitoring.
|
36 months
|
|
Blood sugar
Zeitfenster: 36 months
|
In order to study whether RSD can reduce the blood sugar level and insulin resistance of diabetic patients.
It will be measured by fasting blood glucose, glycated hemoglobin, fasting insulin .
|
36 months
|
|
Cardiac function and structure
Zeitfenster: 36 months
|
The effect of renal sympathetic denervation(RSD) on cardiac function and structure can be measured by echocardiographic(include the degree of cardiac pachynesis, left ventricular ejection fraction,left ventricular end diastolic diameter, ventricular septal thickness and so on).
|
36 months
|
|
Arrhythmia
Zeitfenster: 36 months
|
If a new arrhythmia is discovered during the follow-up, it will be recorded.
Patients may have symptoms of flustered, palpitations, dizziness, amaurosis, syncope and so on, which can be diagnosed by ECG and Holter.
|
36 months
|
|
Pulse wave velocity
Zeitfenster: 36 months
|
So as to study whether RSD can improve the patients' blood vessel elasticity, a pulse wave velocity (PWV)will be carried on.
|
36 months
|
|
Life quality
Zeitfenster: 36 months
|
Life quality on 36-item short-form(SF-36),HRQoL and PRODISQ Health Survey Questionnaire will be carried out during the follow-up to study the patients' life quality.
|
36 months
|
|
Rehospitalization rate
Zeitfenster: 36 months
|
