摘要：

      目的：探讨盆底肌电刺激（PES）改善脊髓损伤（SCI）后神经源性膀胱的疗效。方法： 本研究对21例骶段以上SCI患者进行PES治疗8周，并在PES治疗前1周、PES治疗开始后第2周、第4周、第8周均记录7d的排尿日记并进行B超检查测残余尿量。结果： PES治疗8周后患者24h平均排尿次数由11.9±2.8减少至8.4±1.9次/d、漏尿次数由6.2±3.1减少至2.5±1.7次/d，平均单次尿量由188.1±43.3增加至254.1±42.4 ml/次，差异有显著性意义。结论： 盆底电刺激能有效地改善骶段以上SCI患者神经源性膀胱所致的尿失禁及尿频症状。对于PES治疗参数的选择和PES的长期疗效均有待进一步研究证实。

Abstract:

      Objective: To evaluate the effects of pelvic floor electrical stimulation (PES) on neurogenic bladder in patients with spinal cord injury（SCI）. Method:Twenty-one patients with neurogenic bladder caused by complete or incomplete suprasacral SCI were treated by means of PES twice a day for 8 weeks. All patients were asked to fill out urinary voiding dairy for 7d before electrical treatment, at the 2nd, 4th and 8th week during the treatment course. Ultrasound examination was used to check the residual volume of urine. Result: After treatment, the mean frequency of urinary voiding decreased from 11.9±2.8 to 8.4±1.9time/d ,incontinent episodes per day decreased from 6.2±3.1 to 2.5±1.7time/d and the mean urinary voiding volume increased from 188.1±43.3 to 254.1±42.4ml. Conclusion: PES can improve urinary voiding frequency and incontinence episodes in patients with neurogenic bladder caused by suprasacral SCI. Further studies must be carried out to identify the best stimulation parameters and to verify the long term results.
