目的:探讨肌电图检查在子宫脱垂伴压力性尿失禁诊断及疗效监测中的价值。方法:选择子宫脱垂伴压力性尿失禁20例,动态观察治疗前后肛提肌肌电图检查数据变化。结果:(1)单纯肛提肌损伤8例,术前运动单位平均时限为8.6ms,术后1个月为7.0ms,术后6个月为6.9ms;均未检测到自发电位。(2)神经损伤伴肛提肌损伤12例,术前运动单位平均时限为8.8ms,术后1个月为7.6ms,术后6个月为7.4ms;术前自发电位为正相(■或■),术后1个月及6个月均为(+)。结论:肌电图检查对子宫脱垂伴压力性尿失禁具有较高的诊断及疗效监测价值。
Objective: To investigate the value of EMG in the diagnosis and treatment of uterine prolapse with stress urinary incontinence. Methods: 20 cases of uterine prolapse with stress urinary incontinence were selected, and the data of electromyogram of levator ani muscle before and after treatment were dynamically observed. Results: (1) 8 cases of simple levator ani muscle injury, the average preoperative exercise unit time was 8.6ms, 1 month after surgery was 7.0ms, 6 months after surgery was 6.9ms; were not detected spontaneous potential. (2) 12 cases of nerve injury and levator ani muscle injury, the average duration of preoperative exercise unit was 8.8 ms, 1 month after surgery was 7.6 ms and 6 months after operation was 7.4 ms. The preoperative spontaneous potential was positive (■ Or ■), 1 month after surgery and 6 months were (+). Conclusion: Electromyography has a high diagnostic and curative effect on uterine prolapse with stress urinary incontinence.
