Review of literature
. Multiple superficial veins run subcutaneously and unite near the root of
the penis to form a single (or paired) superficial dorsal vein, which in turn
drains into the saphenous veins. Occasionally, the superficial dorsal vein
may also drain a portion of the corpora cavernosa.
The pendulous penis
The emissary veins from the corpus cavernosum and spongiosum drain
dorsally to the deep dorsal, laterally to the circumflex, and ventrally to the
periurethral veins. Beginning at the coronal sulcus, the prominent deep
dorsal vein is the main venous drainage of the glans penis, corpus
spongiosum, and distal two thirds of the corpora c
avernosa.
Usually, a single
vein, but sometimes more than one deep dorsal vein, runs upward behind the
symphysis pubis to join the periprostatic venous plexus.
1. The infrapubic penis. Emissary veins draining the proximal corpora
cavernosa
join to form cavernous and crural veins. These veins join
the periurethral veins from the urethral bulb to form the internal
pudendal veins.
2. The veins of the three systems communicate variably with each other.
Variations in the number, distribution, and termination of the venous
systems are common.
