女性真性压力性尿失禁尿动力学参数与经阴道分娩次数的相关性研究

目的探讨女性真性压力性尿失禁尿动力学参数与经阴道分娩次数的相关性。方法对56例经阴道分娩生育的的真性压力性尿失禁患者行尿动力学检查，记录腹压漏尿点压测定（ALPP）和最大尿道关闭压（MUCP）、功能尿道长度（FUL）。分别对经阴道分娩次数与各个尿动力学参数进行直线相关分析。结果经阴道分娩次数与ALPP呈负相关（r=-0．349，P〈0.05），与MucP和FUL没有相关关系（r=-0．219，r=-0.178，均P〉0.05）。结论经阴道分娩在压力性尿失禁发病中有一定意义，分娩次数越多，尿失禁越严重。

Correlation between urodynamic parameters and vaginal deliveries in women with genuine stress urinary incontinence

ObjectiveTo identify the relationship between urodynamic parameters and vaginal deliveries in women with genuine stress urinary incontinence(GSI).Methods56 women with vaginal delivery history who were diagnosed as stress urinary incontinence underwent urodynamic tests.Their abdominal leak point pressures(ALPP),maximum urethral closure pressure(MUCP) and functional urethral length(FUL) were recorded,and their Correlation to vaginal deliveries was tested using linear correlation coefficient.ResultsCorrelation between vaginal deliveries and ALPP showed a significant relationship(r=-0.349,P<0.05).Neither MUCP nor FUL showed a close relationship with vaginal deliveries(r=-0.219 and r=-0.178 respectively,P>0.05).ConclusionVaginal delivery plays an important role in the pathogenesis of GSI.The more vaginal deliveries,the more serious GSI.
