目的研究脂肪脊髓脊膜膨出患儿手术前后的尿动力学及体感诱发电位的改善情况,评价手术效果。方法选取2011年7月-2012年11月我院102例脂肪脊髓脊膜膨出患儿,分析患儿手术前后尿动力学各指标好转情况及体感诱发电位各项指标的变化情况。结果行脂肪脊髓脊膜膨出手术后,经尿动力学检查,患儿膀胱容量与正常容量比值较术前有所增加(P<0.05);手术后患儿膀胱顺应性、膀胱逼尿肌压与术前相比差异有统计学意义(P<0.05)。通过体感诱发电位,患儿手术后体感诱发电位的波幅、潜伏期与术前相比差异有统计学意义(P<0.05),而其体感诱发电位波形也由术前的不稳定、缺如改善至稳定、规则。结论患儿尿动力学及体感诱发电位检测各项指标的改善,说明脂肪脊髓脊膜膨出手术的有效性,临床有重要价值。
Objective To study the improvement of urodynamics and somatosensory evoked potentials before and after operation in children with fatty myelomeningosis and evaluate the effect of surgery. Methods From July 2011 to November 2012, 102 children with myeloma of spinal cord from myeloma were enrolled in this study. Changes of each index of urodynamics and changes of somatosensory evoked potentials were analyzed before and after operation. Results After the operation of fatty myelomeningomyosis, the ratio of urinary bladder volume to normal volume in urinary bladder increased significantly compared with that before operation (P <0.05). After operation, bladder compliance, bladder detrusor pressure Compared with the preoperative difference was statistically significant (P <0.05). Through somatosensory evoked potential, the amplitude and latent period of somatosensory evoked potentials in children after operation were significantly different from those before operation (P <0.05), and the somatosensory evoked potential waveforms were also unstable and preoperatively Stable, rules. Conclusion The improvement of urodynamics and somatosensory evoked potentials in children shows that the effectiveness of fatty spinal meningocele surgery is clinically important.
