Int J Impot Res:松弛状态下**收缩期流速和海绵体动脉直径关系与勃起功能异常动态评估

2017-04-30 AlexYang MedSci原创

先前的研究表明了松弛状态下(FS)通过阴茎双多普勒超声(PDDU)所得参数也许可以预测阴茎注射(ICI)后的结果。最近,有研究人员就在FS状态下最高收缩期流速和海绵体动脉直径的关系,以及ICI后PSV和勃起硬度的临床评价(CAEH)进行了研究。该研究召集了经历了因勃起功能异常经历PDDU的50名患者。研究人员进行了在FS状态下PSV和CAD参数的测量,并试图找出20微克前列腺素e1(PGe1)IC

先前的研究表明了松弛状态下(FS)通过阴茎双多普勒超声(PDDU)所得参数也许可以预测阴茎注射(ICI)后的结果。最近,有研究人员就在FS状态下最高收缩期流速和海绵体动脉直径的关系,以及ICI后PSV和勃起硬度的临床评价(CAEH)进行了研究。

该研究召集了经历了因勃起功能异常经历PDDU的50名患者。研究人员进行了在FS状态下PSV和CAD参数的测量,并试图找出20微克前列腺素e1(PGe1)ICI后与PSV和CAEH的关系。研究发现,尽管FS状态下PSV表现出了与ICI后PSV显著的相关性(P=0.04, r=0.21),测试的所有截断值(10, 13 and 15 cm s-1 in FS)具有结合灵敏性和大于80%的特异性来预测不小于30 cm s-1ICI后的PSV。另外,研究人员并未发现FS状态下的PSV与ICI后完全勃起硬度的发展的关系。最后,研究人员指出,尽管FS状态下PSV与ICI后PSV有着统计学上的相关性,但是预测值偏低,因此20微克PGe1的ICI后的反应预测据此是不可靠的。
