摘　　要：目的:探讨排尿性晕厥(micturition syncope,MS)的年龄和性别差异。方法:选择2001年1月至2009年12月在中南大学湘雅二医院晕厥专科门诊就诊或住院的不明原因晕厥或晕厥先兆患者1 542例(3～72岁),进行直立倾斜试验(head-up tilt table test,HUTT)56例诊断为MS(5～67岁,男35例)。分析MS患者与非排尿性晕厥(non mictuition syncope,NMS)患者间年龄、性别、HUTT阳性率的差异及不同性别MS患者年龄、起病年龄、HUTT阳性率差异。结果:MS患者年龄大于NMS患者[5～67(35.5)岁vs.3～72(12)岁,Z=-7.587,P<0.01],且MS患者中成人(>18岁)大于儿童(≤18岁)(9.4%vs.1.0%,χ2=65.689,P<0.01);MS患者中男性多于女性(P<0.01);HUTT阳性率在MS患者和NMS患者之间,差异无统计学意义(P>0.05);男女MS患者HUTT阳性率差异无统计学意义(P>0.05);MS患者中HUTT阳性组与HUTT阴性组就诊年龄及起病年龄差异无统计学意义(P>0.05);男女MS患者就诊年龄及起病年龄差异无统计学意义(P>0.05)。结论:MS患者成人多见,男性所占比例较女性高。Bezold-Jazisch反射可能参与MS的发生。Objective To study the difference between age and gender in patients with micturition syncope（MS）.Methods A total of 56 patients with MS were diagnosed from 1 542（3-72 years old） cases with unexplained syncope or symptoms of presyncope during micturition in our hospital.The age,onset age,positive rate of head up tilt table test（HUTT） and their correlation with age and gender were analyzed.Results The average age of patients with MS was older than that of patients with nonmicturition syncope（NMS）[5-67（35.5）years old vs.3-72（12）years old,Z=-7.587,P0.01].Among the patients with MS,adults（18 years old） were more than children（≤18 years old）（9.4% vs.1.0%,χ2=65.689,P0.01）.There was gender difference in the onset rate of MS（male 5.0% vs.female 2.5%,χ2=6.858,P0.01）.There was no difference in the positive rate of HUTT between the MS and NMS groups,and between the males and females with MS.There was no difference in age and onset age between the HUTT positive and negative group,and between the males and females.Conclusion MS occurs more often in adults and males.Bezold Jazisch reflex may play a role in the mechanism of MS.
