We determined whether the comparison between equilibrium pressure after intracavernous injection of vasodilators and maximal corporeal pressure at gravity cavernosometry could provide information about the relative contribution of arterial inflow and cavernous wall resistance to the erection process.
The results of gravity cavernosometry performed in 68 impotent patients were compared to those of duplex scanning in 53 and penile angiography in 10.
A highly statistically significant (p < 0.01) but nonlinear correlation was observed between the equilibrium pressure after injection and maximal corporeal pressure, which indicates a paramount role of the corporeal veno-occlusive mechanism in the development of penile rigidity. However, in most patients with a pressure increase of more than 30 mm. Hg from the equilibrium pressure after injection to the maximal corporeal pressure, arterial insufficiency was diagnosed by duplex scanning and/or arteriography, and seemed to be the main limiting factor in the development of penile rigidity.
Gravity cavernosometry provides functional information about the corporeal veno-occlusive mechanism and arterial inflow and, therefore, about the relative roles of these mechanisms in the development of penile rigidity.
我们确定海绵体内注射血管扩张剂后的平衡压力与重力海绵体测量法中的最大海绵体压力之间的比较是否能够提供有关动脉血流和海绵体壁阻力对勃起过程相对贡献的信息。
将68例阳痿患者的重力海绵体测量结果与53例的双功扫描结果及10例的阴茎血管造影结果进行比较。
注射后的平衡压力与最大海绵体压力之间观察到高度统计学显著性（p < 0.01）但非线性的相关性，这表明海绵体静脉闭塞机制在阴茎硬度发展中起首要作用。然而，在大多数从注射后的平衡压力到最大海绵体压力增加超过30 mmHg的患者中，通过双功扫描和/或动脉造影诊断出动脉供血不足，并且这似乎是阴茎硬度发展的主要限制因素。
重力海绵体测量法提供了有关海绵体静脉闭塞机制和动脉血流的功能信息，因此也提供了这些机制在阴茎硬度发展中的相对作用的信息。
