盆底功能性磁刺激治疗压力性尿失禁50例分析

The clinical research of functional magnetic stimulation of the pelvic floor treatment for female stress urinary incontinence.

目的探讨功能性磁刺激(functional m agnetic stimu lation,FMS)治疗女性压力性尿失禁的临床效果。方法 2008年1月至2009年6月在辽宁省人民医院对50例压力性尿失禁(stress urinary incontinence,SUI)患者应用FMS进行治疗,年龄(52.1±9.8)岁,产次(1.7±0.5)次。根据治疗前后主观和客观临床参数进行评价,随访3、6、12个月。结果治疗结束后患者生活质量评分平均增加9.34,1h尿垫试验平均漏尿量减少4.65g,3d漏尿次数平均减少5.46次,尿动力学检查初始排尿欲膀胱容量和最大漏尿点压力分别平均增加14.58mL和17.85cmH2O,差异具有统计学意义(P<0.01)。治疗结束后78%患者不再漏尿,16%患者症状得到改善。随诊3、6、12个月,治愈患者中分别有56.41%、79.49%、94.87%症状复发。结论 FMS是治疗SUI的一种安全、简便、无痛、非侵入性的方法,临床效果显著,但疗效维持时间较短。

Objective To evaluate the clinical results of efficiency and applicability of functional magnetic stimulation （FMS） of the pelvic floor for treating stress urinary incontinence in women. Methods A total of 50 women with demonstrable stress urinary incontinence in the People＇s Hospital of Liaoning Province were prospectively studied by treating with functional magnetic stimulation between Jan. 2008 and June 2009. Pretreatment and posttreatment evaluation was accessed by subjective and objective parameters. Patients were followed up for 3,6 and 12 months. Results All of the patients, the mean I-QOL score increases 9.34; in one-hour pad weighting test, the mean pad weight reduces 4.65g;the average number of incontinence episodes three clays decreases 5.46 times ; bladder capacity at first desire to void and valsalva leak point pressure increase respectively 14.58ml and 17.85 cmH2O. All of these test have more significant difference （P 〈 0.01 ）. About 78% of the patients were completely dry and 16% reported improvement after the treatment. In all of the patients who were completely dry, the recurrence rate at 3,6,12 months follow-up was respectively 56.41%, 79.49% ,94.87%. Conclusion Functional magnetic stimulation of pelvic floor is a safe, easy, painless and noninvasive treatment for stress urinary incontinence. This treatment have more significant clinical effect, but it keeps a short term.
