    OBJECTIVE: A retrospective multicenter comparative study was carried out to evaluate whether pregnancy leads to the loss of deformity correction (LOC) in female patients surgically treated for idiopathic scoliosis. METHODS: A total of 128 female patients who underwent segmental spinal instrumentation and fusion for adolescent idiopathic scoliosis (AIS) between 1999 and 2014 were reviewed. Of these patients, 62 became pregnant (surgery-pregnancy group [SPG]), whereas 66 did not (surgery-nonpregnancy [SNP] group). Radiographic parameters were analyzed before surgery, after surgery, before pregnancy, up to 1 year after delivery, and at final follow-up (FFU). Health-related quality of life was analyzed using the Scoliosis Research Society outcome questionnaire (SRS-22r). RESULTS: The mean age at the time of surgery was 16 years in both groups. The mean preoperative major curves were 65 degrees (standard deviation [SD], 12 degrees) versus 67 degrees (SD, 11 degrees), 18 degrees (SD, 9 degrees) versus 17 degrees (SD, 9 degrees) immediately after surgery, and 20 degrees (SD, 8 degrees) versus 20 degrees (SD, 8 degrees) at FFU in the SPG and SNP groups, respectively (P > 0.10 for all comparisons). The mean loss of correction was 3.5 degrees (SD, 3 degrees) in the SPG and 4.5 (SD, 3 degrees) for SNP groups, respectively (P = 0.379). The mean preoperative thoracic kyphosis (T5-T12) was 26.5 degrees (SD, 11.9 degrees) for SPG and 24.7 degrees (SD, 14.5 degrees) for SNP, after surgery 19.2 degrees (SD, 9.5 degrees) for SPG, 18.8 (SD, 8.9 degrees) for SNP and at FFU, 20.3 degrees (SD, 9 degrees) for SPG and 21.3 degrees (SD, 8.5 degrees) for SNP. CONCLUSIONS: Women who have undergone pedicle screw instrumentation and fusion who have had >= 1 pregnancies do not have curve progression or deterioration in the longer-term outcomes compared with patients who have not become pregnant.

    Purpose To determine predictors for postoperative urinary retention in adolescents undergoing posterior spinal fusion for idiopathic scoliosis. Postoperative urinary retention affects almost every third adolescent after spinal fusion for idiopathic scoliosis. There are limited data regarding the risk factors of postoperative urinary retention in this patient group. Methods A retrospective study with prospectively collected urinary retention data from paediatric spine register with 159 consecutive patients (114 females, mean age 15.6 years, range 10-21 years) undergoing pedicle screw instrumentation for adolescent idiopathic scoliosis at a university hospital between May 2010 and April 2020. Postoperative urinary retention was defined as an inability to void after catheter removal and documented residual over 300 mL as confirmed using an ultrasound or by catheterization. Results Postoperative urinary retention was diagnosed in 33% (53 of 159) of the patients during hospital stay. Opioid amount on the day of catheter removal (OR 6.74 [95% CI: 2.47, 18.36], p < 0.001), male gender (OR 2.26 [95% CI: 1.01, 5.05], p = 0.048), and increasing weight (OR 1.04 [95% CI: 1.01, 1.07], p = 0.014) were associated with postoperative urinary retention. Mean opioid consumption on the day of catheter removal was 0.81 mg/kg (95% CI: 0.66, 0.96) in the retention group vs 0.57 mg/kg (95% CI: 0.51, 0.64) in the non-retention group, p < 0.001. Conclusions Higher total opioid consumption, opioid amount on the day of catheter removal, higher weight, and male gender increases the risk of postoperative urinary retention in adolescents with idiopathic scoliosis undergoing posterior spinal fusion.
