Purpose: This study was to evaluate effect and efficiency of S1 selective nerve root block using ultrasonography-guided compared with fluoroscopy-guided for lumbar disc herniation or spinal stenosis patients. Materials and Methods: Between February 2012 and December 2013, 38 patients who were with lower leg radiating pain for more than 1months and underwent S1 selective spinal nerve root block in our institution, were reviewed. They divided into two groups: Group A included 18 patients with ultrasonography-guided and Group B included 20 patients with fluoroscopy-guided. Treatment effectiveness was assessed using a visual analogue scale (VAS) and the Korea Modified Oswestry Disability Index (K-MODI). They were evaluated its preoperatively, postoperatively and 1 month later. We were recorded whole procedure time. Results: VAS was improved from 7.4 to 4.7 at 1 month in group A and from 7.39 to 4.36 at 1month in group B. K-MODI was improved from 72.8 to 43.3 at 1month in group A and from 73.8 to 44.1 at 1month in group B. Whole procedure time were $477.53{\pm}115.02s$, $492.47{\pm}144.38s$ in group A, group B, respectively. But there was no significant difference in VAS and K-MODI between two groups. Conclusion: Ultrasonography-guided sacral nerve root block is effective and accurate method in sacral radiating pain.
