Cavernosograms of a 66-year-old man in the bulbo-urethral vein group. (A) The bulbo-urethral vein (black arrow), the deep dorsal vein (white curved arrow), the cavernosal vein (white arrowhead) and the para-arterial veins (white arrow) were shown while the 19-gauge scalp needle (asterisk) was used to inject the contrast medium. A parallel venous complex of the deep dorsal vein and the cavernosal vein system was noted beneath the symphysis pubis; (B) those veins were enhanced. The glans penis was significantly opacified as shown in panels A and C; (C) after waiting 2 minutes to drain the contrast medium, the para-arterial veins (white arrow), the cavernosal vein (white arrowhead), and the bulbourethral vein (black arrow) were still shown although the parallel venous complex beneath the symphysis pubis faded away.
