本研究的目的是探讨勃起压力(EP)与阴茎海绵体横波速度之间的关系。本研究是在我们先前研究的基础上进行的，其中UVE用于评估海绵体在松弛和直立状态下的粘弹性特性。根据实验装置建立了二维多孔粘弹性有限元模型(FEM)来模拟波在阴茎组织中的传播。将不同水平的EP作用于海绵体，研究了海绵体横波速度与EP的关系。结果表明，在不同的振动频率(100～200赫兹）下，阴茎海绵体的横波速度与EP的增加呈非线性正相关。这些发现首次报道了EP对横波速度的影响，并验证了UVE在男性勃起功能障碍评估中的应用。进一步的评估是必要的，以确定该仪器在诊断和治疗男性勃起功能障碍的临床效用。

英文摘要：
The objective of this study was to investigate the relationship between erectile pressure (EP) and shear wave speed of the corpus cavernosa obtained via a specific ultrasound vibro-elastography (UVE) technique. This study builds upon our prior investigation, in which UVE was used to evaluate the viscoelastic properties of the corpus cavernosa in the flaccid and erect states. A two-dimensional poroviscoelastic finite element model (FEM) was developed to simulate wave propagation in the penile tissue according to our experimental setup. Various levels of EP were applied to the corpus cavernosa, and the relationship between shear wave speed in the corpus cavernosa and EP was investigated. Results demonstrated non-linear, positive correlations between shear wave speeds in the corpus cavernosa and increasing EP at different vibration frequencies (100-200 Hz). These findings represent the first report of the impact of EP on shear wave speed and validates the use of UVE in the evaluation of men with erectile dysfunction. Further evaluations are warranted to determine the clinical utility of this instrument in the diagnosis and treatment of men with erectile dysfunction.
