The goal of this study was to measure corpus cavernosum (CC) penis rigidity with shear wave elastography (SWE) in healthy volunteers and to evaluate the change of rigidity with age.
SWE was performed in 60 healthy volunteers (age range 20-71, mean 47±12,83 years). Volunteers were divided into 2 groups by age (Group 1 age <50, group 2 age ≥50). We assessed SWE in 3 parts of penis (proximal, middle and glans penis) on both sides of CC. All values of SWE (in kilo Pascal) were noted along with volunteers' ages. The measurements were done both with transverse (T) and longitudinal (L) sections. We compared all SW values of penis parts and their alterations with age.
The shear wave elastography values of CC penis increased with increasing age (p<0,01). There was no significant difference between both sides of CC penis (p<0,05). We calculated no significant difference between T and L sections of all parts of penis (p<0,05).
SWE can provide noninvasive quantitative data of CC penis rigidity and its alteration with age. These data may create a new approach in the evaluation process and treatment options for penile pathologies.
本研究的目的是在健康志愿者中使用剪切波弹性成像（SWE）测量阴茎海绵体（CC）的硬度，并评估硬度随年龄的变化。
对60名健康志愿者（年龄范围20 - 71岁，平均47±12.83岁）进行SWE检查。志愿者按年龄分为2组（第1组年龄<50岁，第2组年龄≥50岁）。我们在CC两侧的阴茎3个部位（阴茎近端、中部和龟头）评估SWE。记录所有SWE值（以千帕斯卡为单位）以及志愿者的年龄。测量在横切（T）和纵切（L）面上进行。我们比较了阴茎各部位的所有SW值及其随年龄的变化。
阴茎CC的剪切波弹性成像值随年龄增加而升高（p<0.01）。阴茎CC两侧之间无显著差异（p<0.05）。我们计算得出阴茎所有部位的T切面和L切面之间无显著差异（p<0.05）。
SWE可以提供阴茎CC硬度及其随年龄变化的无创定量数据。这些数据可能为阴茎疾病的评估过程和治疗选择创造一种新方法。
