Cavernosograms of a 56-year-old man in the deep dorsal vein group with conspicuous corpus spongiosum. (A) While the tip of a 19-gauge scalp needle (white asterisk) was positioned in the corpora cavernosa, the deep dorsal vein (white curved arrow) and the bulbo-urethral vein (white arrowhead) were shown after injection of the contrast medium; (B) those veins were enhanced while the corpus spongiosum (black asterisk) was conspicuously demarcated. In addition the cavernosal vein (white arrow) was presented beneath the deep dorsal vein (DDV) (between dotted lines) and the left corpus cavernosum (between lines). Note that the right femoral vein (cross) was well-opacified; (C) the deep dorsal vein (white curved arrow and also between dotted lines), part of the bulbo-urethral vein (white arrowhead) were still presented and the corpus spongiosum (black asterisk) was filled when the introduction of an artificial erection. Again the corpus cavernosum (between lines) was measured.
