Objectives: Lumbar spinal stenosis (LSS) is a severe degenerative disease that affects the human spine. The relationship between its symptoms and dural sac diameter is not apparent. In this study, we investigated the relationship between clinical signs of LSS and morphological parameters using magnetic resonance imaging (MRI) data. Methods: A total of 218 patients included in the study. All patients were divided into two groups(group A- the level of the dural sac diameter <70 mm2 and group B- the level of the dural sac diameter >70 mm2). Clinical signs as the estimated walking distance (EWD), visual analog scale (VAS) and Oswestry disability index (ODI). Results: MRI data, and types of surgery recorded for each patient. Decompressive laminectomy and fusion (DL+F) or unilateral laminotomy bilateral decompression (ULBD) preferred in 76 patients of this group. Conclusion: Magnetic resonance imaging (MRI) has an essential role in the diagnosis of LSS. Our study showed a positive correlation between dural sac diameter and EWS, VAS and ODI values on axial T2-weighted MR images of patients undergoing surgery. Keywords: Lumbar spinal stenosis, magnetic resonance
