A corpus cavernosum penis (singular) (from Latin, characterised by "cavities/ hollows" [2] of the penis, pl.: corpora cavernosa) is one of a pair of sponge-like regions of erectile tissue, which contain most of the blood in the penis of several animals during an erection.
Peyronie's disease is a connective tissue disorder involving the growth of fibrous plaques in the soft tissue of the penis. Specifically, scar tissue forms in the tunica albuginea, the thick sheath of tissue surrounding the corpora cavernosa, causing pain, abnormal curvature, erectile dysfunction, indentation, loss of girth and shortening. [2] [3]
From the internal surface of the fibrous envelope of the corpora cavernosa penis, as well as from the sides of the septum, numerous bands or cords are given off, which cross the interior of these corpora cavernosa in all directions, subdividing them into a number of separate compartments, and giving the entire structure a spongy appearance.
Pain occurs in about 20 to 70 percent of men with Peyronie’s disease during the acute phase. Shortening or narrowing of the privates. In severe cases, some men lose around 0.5-1.5 cm of length.
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.
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. In the flaccid penis (Figure 3), the normal cavernous arteries show a systolic peak between 11 and 20 cm/s.
Immediate pain and swelling of the penis, rapid erection loss, discoloration of the penile shaft [1] Complications: Gangrene, erectile dysfunction, Peyronie's disease: Causes: Blunt trauma to an erect penis: Risk factors: Sexual intercourse, masturbation: Diagnostic method: Based on symptoms, ultrasound: Differential diagnosis: Testicular ...
These can be traumatic injuries, penile surgeries, disfiguring and fibrosing diseases of the penis, such as Peyronie's disease. [6] In Peyronie's disease, the change in penile curvature affects normal sexual intercourse as well as causing erectile dysfunction due to disruption of blood flow in the cavernous bodies of the penis.
