Abstract Renal Artery Sympathetic Denervation (RDN) can lower blood pressure. Different ablation catheters (single electrode, multi‐electrode) have different scopes of ablation (renal artery main stem and branches). Few studies have compared the advantages and disadvantages of different ablation catheters and different procedures in terms of antihypertensive efficacy. To compare the efficacy and safety of 3D reconstruction radiofrequency ablation (3DRA) and basket multi‐electrode radiofrequency ablation (BMRA) in Renal Artery Sympathetic Denervation. Fifty‐three patients with Refractory hypertension (RHT) were divided into BMRA, (n = 28) and 3DRA(n = 25). BMRA group used a stereobasket multi‐electrode ablation catheter with a controlled ablation temperature of 60°C and an ablation time of 120 s per site. 3DRA group used a NavStar pressure‐monitored perfusion monopolar ablation catheter with a controlled ablation temperature of 40°C, an ablation time of 40 s per site, and an ablation energy of 12 W. Baseline and RDN parameters and complications were compared in both groups. Home and 24 h ambulatory blood pressure, type of anti‐hypertensive medication taken, and serum creatinine were followed up at 1, 3, 6, 12, and 24 months after the RDN. There were no differences in baseline characteristics between the two groups. (23.14 ± 2.00)months of follow‐up in the BMRA group resulted in a total of (25.86 ± 8.61) loci ablation. (19.28 ± 7.40)months of follow‐up in the 3DRA group resulted in a total of (21.04 ± 6.47)loci ablation. Home SBP was significantly lower in both groups at 1 month after RDN treatment compared to baseline(H‐SBP/mmHg: BMRA 149.9 ± 10.59 vs. baseline 168.36 ± 12.76; 3DRA 152.6 ± 14.91 vs. 164.89 ± 12.96, both p
