| 【Abstract】 Objectives: To evaluate the outcomes of bladder function in patients with tethered cord syndrome (TCS) by homogeneous spinal-shortening axial decompression(HSAD). Methods: From April 2013 to July 2016, 16 patients(6 males, 10 females) with TCS, aged 11-64 years old(average, 29.9±16.7 years old), underwent HSAD. The ICI-Q-SF score was used to evaluate pre- and post-operative bladder function. The pre- and post-operative parameters, including safe bladder capacity, bladder compliance, detrusor leak point pressure and bladder residual urine volume, were measured according to urodynamic. Results: 16 patients were followed up for 15 to 54 months(average, 32.4±10.1months). The ICI-Q-SF score was decreased from preoperative 14.94±4.15 to 7.63±4.40 at final follow-up(P<0.01). The safe bladder capacity was increased from preoperative 155.31±75.33ml to 252.69±64.94ml at final follow-up(P＜0.05). The bladder compliance was improved from preoperative 8.56±5.78ml/cmH2O to 23.10±12.05ml/cmH2O at final follow-up(P＜0.05). The detrusor leak point pressure was decreased from preoperative 43.12±17.96cmH2O to 30.44±13.96cmH2O at final follow-up(P＜0.05). The bladder compliance was increased from preoperative 8.56±5.78ml/cmH2O to 23.10±12.05ml/cmH2O at final follow-up(P＜0.05) The bladder residual urine volume had no statistic difference(P>0.05). Conclusions: HSAD could obviously improve the urinary function and urodynamic indexes of patients with TCS. |
