The superficial dorsal vein of the penis belongs to the superficial drainage system. It is located within the superficial dartos fascia, a continuation of the Colles' fascia, on the dorsal surface of the penis and, in contrast to the deep dorsal vein, it lies outside the deeper Buck's fascia. [2]
Venous leak is an inability to maintain an erection in the presence of sufficient arterial blood flow through the cavernosal arteries of the penis. [6] The defect lies in the excessive drainage of veins in the cavernosal tissue of the penis, which undermines normal erectile function.
Venous drainage is performed by the deep and superficial dorsal veins of the penis. The dorsal arteries of the penis are located adjacent to the deep dorsal vein and a cavernous artery is located in the center of each corpus cavernosum. On color Doppler, the cavernous arteries present single phase flow.
Arteries and veins of the penis. The penile artery (also known as the common penile artery) is the artery that serves blood to the penis. It is a terminal branch of the internal pudendal artery, along with the scrotal artery. It subdivides into three arteries, the bulbourethral artery, the dorsal artery of the penis and the cavernosal artery.
The diagnosis was established by observing the rapid drainage of a contrast agent through the deep dorsal vein while conducting pharmacodynamic ultrasonography. The treatment involved the surgical resection and ligation of a segment of the deep dorsal vein, a procedure that aimed to reduce pathologic venous outflow from the glans during ...
They begin in the deep veins of the vulva and of the penis and scrotum, issuing from the bulb of the vestibule and the bulb of the penis, respectively. They accompany the internal pudendal artery, and unite to form a single vessel, which ends in the internal iliac vein .
Venous drainage of the penis begins at the base of the glans. Small tributaries deriving from the corona form a venous plexus at the neck of the penis, known as the retro-coronal, or retro-balanic, plexus. [27] Smaller paired venules run into the frenulum and the glans from its ventral surface. [28]
The prostatic veins form a well-marked prostatic plexus which lies partly in the fascial sheath of the prostate and partly between the sheath and the prostatic capsule. [citation needed] It collects blood from the prostate, and (via the v. dorsalis profunda clitoridis) the corpora cavernosa of penis. [1]
