  • When it is deemed impossible to perform denervation on both renal arteries according to the discretion of the investigator
• Those with a medical history or a history of surgery/procedure that is unsuitable for renal denervation therapy
  • Renal denervation therapy
  • Renal artery stenting within 3 months prior to surgery
  • Polycystic kidney disease (PKD)
  • Atrophic kidney
  • Kidney transplant
  • Dialysis due to end-stage renal disease
  • Any surgery performed on the both kidney
  • FMD(Fibromuscular dysplasia)
• Those who receive SGLT2 inhibitors or GLP-1 agonists within 90 days before Screening 1, or those who are expected to require treatment during the clinical trial period(but if on continuous medication without changes more than 90days can be enrolled)
• Those who have secondary hypertension or are receiving sympathomimetic drugs that affect hypertension
• Those with a history of the following cardiovascular diseases or accompanying diseases
  • Myocardial infarction occurring within 3 months prior to Screening 1

• Those who have taken non-steroidal anti-inflammatory drugs (NSAIDs) twice or more per week for pain control within 1 month prior to Screening 2
• Those receiving antiretroviral drug therapy due to HIV infection (except when there is a documented history of hypertension prior to initiation of antiretroviral drug therapy)
• Those with the following confirmed drug administration history in relation to narcotic drugs:
  • A history of abuse of narcotic drugs
  • Those who use methadone
  • Those who have used narcotic drugs twice or more within 1 month prior to Screening 1
• Those with drug or alcohol dependence that has not been cured at the time of Screening 1, and who lack the ability or are unable to understand and follow the instructions required in this clinical trial
• Those who are scheduled to undergo a surgery/procedure that is expected to affect the efficacy and safety of this clinical trial according to the discretion of the investigator
• Those who have received other investigational products or investigational medical devices within 4 weeks prior to Screening 1 (however, such patients may be enrolled if such products of devises do not affect the efficacy and safety assessment of this clinical trial according to the discretion of the investigator)

Other illness

• Those with a confirmed comorbidity or a history of surgery/procedure that is unsuitable for posterior retroperitoneal approach required for renal denervation therapy
  • Surgical history using the retroperitoneal approach
  • Fibrosis of the retroperitoneal region
  • Inflammation of the retroperitoneal region
  • Extreme obesity (body mass index (BMI) \> 40 kg/m2)
  • Risk of elevated intracranial pressure
• Those who are likely to experience safety problems due to blood pressure drop according to the discretion of the investigator (e.g., heart valve stenosis, peripheral vascular disease, aortic aneurysm, and high-risk groups for bleeding (thrombocytopenia, hemophilia, severe anemia, etc.)
• Those who have difficulty in measuring blood pressure accurately according to the discretion of the investigator (e.g., if the circumference of the upper arm is larger than the cuff size of the blood pressure monitor, those with arrhythmia, etc.)
• Those with primary pulmonary hypertension
• Those with confirmed bleeding diathesis, coagulation disorder, or refusal to receive transfusions
• Those with a history of contraindications to the use of contrast agents, anaphylactic reactions, or uncontrolled allergic reactions

Lab values

• eGFR\* \< 45 mL/min/1.73 m2
  • eGFR calculation formula (MDRD equation) 175 × (sCr)-1.154 × (age)-0.203 × (0.742 if female)
• Those with type 1 diabetes or uncontrolled type 2 diabetes\*
  • Uncontrolled type 2 diabetes: HbA1c ≥ 8.0%
  • HbA1c will be tested in Screening 2 if the confirmed HbA1c result is from the test conducted 3 months before Screening 2 or if additional tests are deemed necessary according to the investigator discretion due to a history of inadequately controlled blood glucose level.

Other

• Subjects cannot be enrolled in the clinical trial if they meet any of the following criteria
• Those with at least a 20-mmHg decrease in office SBP or at least a 10-mmHg decrease in office DBP accompanied by symptoms, measured within 3 minutes of standing up during Screening 2(but if orthostatic hypotension is clearly due to Benign Prostatic Hyperplasia, subject can be enrolled)
• Those who are chronically on oxygen-assisted or mechanical ventilation (e.g., CPAP, BiPAP) (however, usage due to sleep apnea is exempted)
• Night shift workers
• Women who are pregnant, lactating, or plan to become pregnant during the period of the clinical trial
• Other subjects who are deemed ineligible to participate in this clinical trial according to the investigator's discretion

• Subjects are deemed eligible for this clinical trial only if they meet all of the following criteria:
• Male and female patients aged between 19 and 79 years old
• Resistant hypertensive patients on stable regimen of at least 3 antihypertensive medications\* for at least 4weeks prior Screening1 and those who are willing to continue existing antihypertensive medications during run- in period and till 3 months after surgery from Screening 1
