文摘Previous studies have shown that, anode block electrical stimulation of the sacral nerve root can produce physiological urination and reconstruct urinary bladder function in rabbits.

文摘目的:探讨骶神经磁刺激对脊髓损伤后逼尿肌无力型膀胱的影响。方法:采取随机分组的方法将36例脊髓损伤合并逼尿肌无力型膀胱患者分为试验组与对照组。两组患者均接受常规康复治疗,试验组对S3神经根进行重复功能性磁刺激(repetitive functional magnetic stimulation,r FMS)治疗。于治疗前、治疗4周后分别观察2组患者的简易膀胱容量测定、膀胱超声及焦虑自评量表等指标。结果:2组患者最大自排尿量、平均自排尿量、残余尿量、膀胱初感觉容量及焦虑自评评分与治疗前相比均有所改善,治疗后试验组的最大自排尿量、平均自排尿量均显著优于对照组,具有显著性差异(P<0.05)。结论:重复功能磁刺激作用于骶神经根对治疗脊髓损伤后逼尿肌无力型患者疗效明显优于常规治疗,疗法为临床上治疗逼尿肌无力型神经源性膀胱提供新思路。
