尿道综合征患者尿道外括约肌肌电图检测分析

目的　探索尿道综合征 (US)病人尿道外括约肌肌电图变化特征。方法　门诊筛选US病人5 4例。以有无神经症诊断分为两组 ,以丹迪 2 0 0 0肌电图仪在憋尿期、排尿期行安定注射前后尿道外括约肌肌电图 (EMG)的测定。组间差异用 χ2 检验分析。结果　单纯性US病人安定用药前后之憋尿期、排尿期尿道外括约肌EMG无变化 ,精神源性US病人安定用药前后憋尿期、排尿期EMG有变化 ,组间比较有显著性差异。结论　尿道外括约肌EMG测定在US诊断中具有鉴别诊断价值 ,在US治疗上有指导意义

Detection and analysis of urethral external sphincter in patients with urethra syndrome (US)by EMG

Objective To explore the changes of EMG of urethral external sphincter in the patients suffering from US.Methods Fifty four outpatients suffering from US be divided into two groups,one having neurosis,the other not.Before and after injecting diazepam,authors respectively determined the EMG of urethral external sphincter in keeping urine phase and urinating phase by Dandi 2000 EMG machine.The compare of the difference between groups was by means of x 2 analysis.Results There was no change of EMG of urethral external sphincter in keeping urine phase and urinating phase between before and after injecting diazepam in the patients suffering from simple US,but there were changes in psychogenic US,the changes have significant difference (P<0.05).Conclusions The determination of EMG of urethral external sphincter has distinguishing value in the diagnosis of US;it can guide the treatment of US.
