This study aimed to evaluate the Persian Discectomy Successful Score (PDSS) in patients diagnosed with lumbar disc herniation undergoing discectomy. The PDSS first was developed based on the JOA score. It is a linear transformation of patients’ pre-operative JOA score that can predict the successful rate of surgery outcome in advance (PDSS= -1.036 × preoperative JOA + 23.635). Methods: A total of 103 patients with lumbar disc herniation submitted for discectomy operation were entered into the study during two years of study. A sensitivity analysis was carried out to examine the accuracy of the PDSS. For the analysis of the results, patients’ pre- and post-operative JOA score was used as gold standard to calculate the actual difference observed (JOA pre-operation minus JOA post-operation = DJOA) and to compare this measure (difference) with estimation derived from the PDSS. Results: The mean age of patients was 47.4 ± 9.7 (ranging from 17 to 79) years and were followed for at least three months. The difference between pre and postoperative JOA score (15.4 ± 3.7) was statistically significant (P Conclusions: It seems that the preoperative JOA is able to predict discectomy results in patients with lumbar disc herniation. To confirm the findings of this study, a longitudinal study is recommended.
