Abstract
Dynamic carvernosography before and after papaverine injection into the corpus cavernosum of 6 sexually normal volunteers and 44 impotent patients was performed with digital subtracting angiography technique. The average infusion rates in 26 patients with venous leakage were 325.5 ml/min for induction of erection and 161 ml/min for maintenance. The results for the remaining 18 impotent patients without venous leakage were 128.8 ml/min for induction and 56.9 ml/min for maintenance. Similarly, the control group had average infusion rates of 128.3 ml/min for induction and 58.3 ml/min for maintenance. After papaverine injection the average infusion rates decreased to 131 ml/min (induction) and 59 ml/min (maintenance) in patients with venous leakage, 38.4 ml/min and 14.6 ml/min in the impotent patients without venous leakage and 35 ml/min and 14.1 ml/min in the control group, respectively. It was also noticed that in the control group filling of the superficial and deep veins may occur during the flaccid phase which disappeared with induced erection. Therefore we suggest intracavernous papaverine injection with dynamic cavernosography. The digital subtracting technique eliminates unnecessary images, providing a more accurate diagnosis of venius incompetence.
