Abstract
Background: Scoliosis is one of the most common spinal deformities with subsequent decrease in pulmonary function. The effects of surgical correction on the pulmonary function of patients with adolescent idiopathic scoliosis are controversial. The purpose of the present study was to compare the postoperative pulmonary function changes in different surgical approaches chosen for its correction.
Methods: Sixty-five patients with adolescent idiopathic scoliosis who had undergone corrective spinal surgery in Shafa Yahyaian Hospital since 1997 to 2007 and had documented preoperative pulmonary function test report, included in our study. The patients had documented preoperative pulmonary function tests and were divided into three groups based on their surgical approach. The first group was comprised of 25 patients who had undergone posterior spinal fusion (PSF), the second group included 29 patients who had anterior and posterior spinal fusion (ASF+PSF), and the third group consisted of 10 patients who had posterior spinal fusion and thoracoplasty (PSF+ thoracoplasty). The preoperative and the final follow-up values of absolute and percent predicted forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were compared and their relations with the undertaken surgical approach were evaluated.
Results: There were no significant correlations between the surgical approaches and changes in the pulmonary function tests (P>0.05). FVC and FEV1 values were similar to preoperative values in all groups after a minimum follow-up of two years.
Conclusion: There were no significant differences between different surgical approaches for adolescent idiopathic scoliosis regarding the pulmonary function test results after at least two years of follow-up.

Abstract
Background: Congenital scoliosis (CSC) and Idiopathic scoliosis (ISC) are complex spinal disorders that may involve neurological components affecting bladder function. Surgery remains the primary treatment for significant deformity, and in selected cases, correction of an associated tethered cord is also required. Given the potential interaction between spinal pathology and lower urinary tract function, this study examined changes in urodynamic findings before and after treatment in patients with CSC and ISC.
Methods: This retrospective cross-sectional study included patients with scoliosis who were presented to the Neurosurgery Clinic at Sina Hospital between September 2016 and September 2018. Preoperative and postoperative urodynamic study (UDS) results were reviewed, and statistical analyses were performed using SPSS version 24.
Results: Thirty-one patients were analyzed, consisting of 10 males (32.2%) and 21 females (67.7%), with a mean age of 14.18 years (median: 13 years). Among the 12 patients with CSC, 10 (83.3%) showed abnormal UDS prior to surgery. In contrast, 13 of 19 patients with ISC (68.4%) demonstrated normal baseline UDS. Following treatment, normalization occurred in 10 CSC patients (83.3%) and in 14 ISC patients (73.7%) (P=0.008). Before surgery, 15 of the 23 patients without a tethered cord (65.2%) had normal UDS, whereas all 8 patients with a tethered cord exhibited abnormal findings. Of the 12 patients with abnormal preoperative UDS, 3 (25%) showed no postoperative change, while 12 patients demonstrated normalization and 4 continued to show abnormal results (McNemar test, P=0.039). Improvement was also observed in 7 of the 8 patients (87.5%) with a tethered cord (P=0.57).
Conclusion: Scoliosis surgery, particularly when combined with tethered cord release, was associated with meaningful improvement in urodynamic function. Urodynamic abnormalities were more common among CSC patients before intervention, and the presence of a tethered cord contributed to greater urinary dysfunction across both scoliosis types. These findings highlight the importance of thorough preoperative urodynamic assessment to guide management and anticipate postoperative outcomes.
