【摘要】 作者回顾性分析了 2 47例经双核素阴茎海绵体血液动力学动态检查 (Penograme) ,确诊为静脉性勃起功能障碍患者 [阴茎动脉系统显像指数 (PIA) 15 8.8± 6 7.5 ,阴茎静脉系统显像指数 (PIV) - 6 3.7± 12 .4]的硬度测试仪 (Rigiscan)资料。 2 47例中 ,周径变化线或硬度指数高点间连线呈“锯齿波”样变化者 196例 ,其PIA 142 .1± 45 .9,PIV - 5 7.6± 5 .1;呈“斜向降低”者 40例。PIA 145 .9± 5 3.2 ,PIV - 6 4.2± 7.6 ;无变化者 (未勃起 )者 11例 ,PIA140 .4± 47.1,PIV - 6 0 .9± 9.8;三种变化之间 ,PIA、PIV无统计学差异 (P >0 .0 5 )。作者认为 ,“锯齿波”及“斜向降低”样变化是静脉性勃起功能障碍Rigiscan检查的主要表现 ,其机理是因为静脉回流过快导致阴茎海绵体内压力不稳定甚至渐降低所至更多还原

【Abstract】 The rigiscan materials of 247 cases,which had been diagnosised as venous erectile dysfunction by Penogram examinatrion[PIA(Penogram Index of Aterial system)are 158.8±67.5,PIV(Penogram Index of Venous system) are -63.7±12.4)]were analyzed.In 247 cases,the circumference variation line or stiffness index high point connection line of 196 cases appeared as “dent wave”,whose PIA are 142.1±45.9 and PIV are -57.6±5.1;40 cases appeared as “athwart lower”,whose PIA are 145.9±53.2 and PIV are -64.2±7.6;and 11 cases (11/247) haven’t any change (no erection),whose PIA are 140.4±47.1 and PIV are -60.9±9.8.There is no statistical difference ( P >0.05) between PIA and PIV among the above three changings.The authors considered that the “dent wave” and “athwart lower” are the major venous erectile dysfunction in rigiscan examination,the mechanism is that the venous regurgitation is too fast to induce spongiosal internal pressure unstable or reduce gradually.更多还原
