A study was done in 21 men to identify individuals with venous leakage as a cause of impotence. Combined pressure flow measurement and cinecavernosography were performed before and after the injection of papaverine into the corpora. After papaverine injection, erections and/or higher pressures occurred at lower flow rates in all the men. The venous drainage of the corpora decreased or disappeared in most subjects while the corpora became larger and contained more contrast material. The findings suggest that an active venous obstructive mechanism is important during erection, can be induced by the administration of papaverine, and should be evaluated in impotent men.
对21名男性进行了一项研究，以确定因静脉漏导致阳痿的个体。在向海绵体内注射罂粟碱前后，进行了联合压力流测量和海绵体造影。注射罂粟碱后，所有男性在较低流速下出现勃起和/或更高压力。大多数受试者海绵体的静脉引流减少或消失，而海绵体变大且含有更多造影剂。这些发现表明，活跃的静脉阻塞机制在勃起过程中很重要，可由罂粟碱诱导产生，并且应该在阳痿男性中进行评估。
