상세 설명

Chronic kidney disease(CKD) is a global and growing public health problem, and its frequency increases with age. The major complications of CKD involve losing renal function and cardiovascular disease, which result in significant morbidity, mortality, and cost. The main measures for treatment of CKD are optimizing drug therapy and renal replacement therapy. Optimizing drug therapy, including vascular angiotensin-converting enzyme inhibitors, calcium antagonists, diuretic, beta adrenoceptor blocking agent, statins, platelet aggregation inhibitor, anticoagulants and so on. However, the situation for treatment of CKD is not satisfying. Sympathetic overactivity plays a key role in the development and progression of CKD. Sympathetic nerve activity was increased in patients with all stages of CKD, which was associated with cardiovascular events and all-cause mortality. At the same time, hypertension and proteinuria become the most important risk factor for progression of CKD. Recently, many clinical researches have verified that Catheter-based renal sympathetic denervation can safely be used to substantially reduce muscle and whole-body sympathetic-nerve activity (MSNA) and whole-body norepinephrine spillover. Simultaneously, a marked reduction in blood pressure, sleep apnea severity and urine micro albumin level is apparent, with a improvement glucose tolerance. Sympathetic activation, high norepinephrine level, hypertension, glucose tolerance abnormity, proteinuria and obstructive sleep apnea are all recognized as independent risk factors for the development and progression of CKD. So, we design this randomized parallel control clinical study to demonstrate whether RSD can slow the progression of CKD and reduce the rate of all-cause mortality effectively and securely.

활성 비교기: 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).
절차: RSD
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.
