压力性尿失禁诊疗135例临床分析
Objective The purpose of this study is to evaluate and compare the two different treatments by researching 135 cases with stress urinary incontinence .Methods From June 2006 to June 2010,135 patients with stress urinary incontinence were treated in Department of Gynecology and Obstetrics of Peking University Shenzhen Hospital.91 cases of them were treated with low frequency electric stimulation and biofeedback therapy (Group A),and the other 44 cases were treated by improved transobturaor tension -free vaginal tape(TVT-O) and TVT-O (Group B).Then,we compared these two groups by whole recovery rate ,recovery rate of patients with urge incontinence , charge of treatment and complication , respectively.Results Group B's recovery rate for stress urinary incontinence was 100%.Ⅰ degree stress urinary inconti-nence in Group A's recovery rate was higher;Ⅱ degree patients'recovery rate for stress urinary incontinence was lower;Ⅲ degree patients'recovery rate was 0%.Only 1 case showed abnormal urine stream;2 cases showed urinary retention,but the symptoms disappeared after the treatment .No significant complication in Group A.There were huge differences of the expense between the two groups .The effect in Group A for pa-tients with urge incontinence was good,but there was no effect shown in Group B.Conclusions The two treatments are safe and effective for stress urinary incontinence ,but there are existed prominent differences of the therapeutic efficacy between the two groups .

重症肌无力重复神经刺激的研究
AIM: To investigate normal value range of low-frequent repeated nerve stimulation (RNS): whether different low-frequent stimulation and differentmuscles have different normal value range. METHODS: Low-frequent(3 c/s and 5 c/s) RNS of 30 healthy people and 27 myasthenia gravis (MG)patients were test. RESULTS: Superior limit of amplitude of wave attenuationvalue of low-frequent RNS (-x :±2.5s) of different muscles (orbicularis oculimuscle, deltoid muscle and abductor muscle of little finger) of healthy peoplewas 5.45% -7.55%. According to our normal value standard, RNS positiverate of MG group was 85%; according to the current criteria (amplitude ofwave attenuation value＞10%), positive rate of MG group was 70%, therewas no apparent difference in RNS positive rate(P＞0.1). Some labsadopted the criteria that amplitude of wave attenuation value ＞ 15%, ac-cording to this criteria, positive rate of MG group was 51%. Compared withpositive rate (85%) obtained according to our criteria, there was apparentdifference( P ＜0.01). CONCLUSION: Each labs should establish theirown normal value standard according to difference muscle and differentnt fre-quent. If adopt universal standard, amplitude of wave attenuation value 8%or 10% was sugsested.
