Abstract

INTRODUCTION

The aim of this prospective study was to evaluate the usefulness of measurement of axial penile rigidity, compared with radial penile rigidity.

PATIENTS AND METHODS

Twenty-two patients, aged 21-75 years old (a mean of 50), with erectile dysfunction underwent axial penile rigidity measurements by the digital inflection rigidometer (DIR) as well as radial penile rigidity measurements by the RigiScan Plus during intracavernous pharmacological erection testing.

RESULTS

A significant correlation was recognized between axial rigidity, and radial rigidity at the tip (p = 0.0024) and base (p = 0.0098) of the penis. In 10 patients, the DIR revealed axial rigidity of 550 g or more, and they also had radial rigidity of 60% or more at the tip and base. In 14 and 17 subjects, radial rigidity of 60% or more was observed at the tip and base, respectively. Four of the former 14 and 7 of the latter 17 had axial rigidity <550 g.

CONCLUSIONS

A RigiScan results of radial rigidity of 60% or more should be interpreted cautiously and not necessarily regarded as normal.

摘要

引言

本前瞻性研究的目的是评估阴茎轴向硬度测量相对于阴茎径向硬度测量的效用。

患者与方法

22名年龄在21 - 75岁（平均50岁）的勃起功能障碍患者在海绵体内药物性勃起测试期间，通过数字弯曲硬度计（DIR）进行阴茎轴向硬度测量，并通过RigiScan Plus进行阴茎径向硬度测量。

结果

阴茎轴向硬度与阴茎顶端（p = 0.0024）和基部（p = 0.0098）的径向硬度之间存在显著相关性。10名患者的DIR显示轴向硬度为550克或更高，并且他们在顶端和基部的径向硬度也为60%或更高。在14名和17名受试者中，分别在顶端和基部观察到60%或更高的径向硬度。前14名中的4名和后17名中的7名轴向硬度<550克。
