Insufficient penile erection due to abnormal drainage of cavernous bodies.

Four men were referred for incomplete erection of the penis. All had abnormal venous outflow from the cavernous bodies: 1 iatrogenic fistula from the cavernous body to the glans, 1 congenital fistula from the cavernous body to the glans, 1 with several congenital large veins connecting the interior of the cavernous body to the outer veins, and 1 who suddenly lost the ability for erection was found to have a venous leak through scar tissue in the tunica albuginea. They were all operated on and the visible leaks closed. Three of them were functionally greatly improved.
