We compare the results of the resistance index generated by duplex scanning and the corporeal pressure generated by the intracavernous injection test followed by gravity cavernosometry.
We examined 40 impotent subjects with duplex scanning and gravity cavernosometry.
For the entire group a significant correlation (r = 0.77, p < 0.001) was found between the resistance index and intracavernous injection test, and between the resistance index and the gravity cavernosometry (r = 0.62, p < 0.01). Excluding the results of patients who had a full erection during scanning, the correlation between the resistance index and intracavernous injection test remained but the correlation between the resistance index and gravity cavernosometry disappeared (r = -0.02, p > 0.05).
There was no relationship between the value of the resistance index and the cavernous wall resistance, except in patients capable of developing a full erection after vasodilator injection.
我们比较了双功扫描产生的阻力指数结果与海绵体内注射试验后重力海绵体测压法产生的体内压力结果。
我们对40例阳痿患者进行了双功扫描和重力海绵体测压法检查。
对于整个组，在阻力指数与海绵体内注射试验之间，以及阻力指数与重力海绵体测压法之间均发现显著相关性（r = 0.77，p < 0.001）（r = 0.62，p < 0.01）。排除扫描期间完全勃起患者的结果后，阻力指数与海绵体内注射试验之间的相关性仍然存在，但阻力指数与重力海绵体测压法之间的相关性消失（r = -0.02，p > 0.05）。
阻力指数值与海绵体壁阻力之间没有关系，除了在注射血管扩张剂后能够完全勃起的患者中。
