We define the precise meaning and diagnostic significance of the resistance index generated by duplex scanning.
In 80 patients penile rigidity was clinically evaluated and a penile duplex scan was performed after intracavernous injection of 10 microg. prostaglandin E1. The intracavernous equilibrium pressure was measured in 34 of these patients.
We found a statistically highly significant linear relationship among cavernous pressure, resistance index and penile rigidity (p <0.001).
The resistance index and clinical degree of penile rigidity are 2 expressions of intracavernous pressure. Clinical observation of erection is equivalent to the resistance index in screening for cavernous leakage.
我们定义了双功扫描所产生的阻力指数的确切含义及诊断意义。
对80例患者进行阴茎硬度的临床评估，并在海绵体内注射10微克前列腺素E1后进行阴茎双功扫描。其中34例患者测量了海绵体内平衡压力。
我们发现海绵体压力、阻力指数和阴茎硬度之间存在统计学上高度显著的线性关系（p<0.001）。
阻力指数和阴茎硬度的临床程度是海绵体内压力的两种表现形式。勃起的临床观察在筛查海绵体漏方面等同于阻力指数。
