Some authors consider the artery to be called the penile artery from here on, giving rise to: Bulbar artery supplying the bulb of the urethra, posterior corpus cavernosum, and bulbourethral glands (with the normal capillary blush seen within the bulbar spongiosa), Urethral (spongiosal) artery supplying the corpora spongiosa and providing anastomoses with the dorsal artery of the penis at the glans penis, The deep artery of the penis (cavernosal artery), which divides into helicine arteries that enter the lacunar spaces almost at right angles from the cavernosal artery. BJU International. Treatment might be needed to prevent further episodes. Do you have brochures, or can you suggest websites that explain more about priapism? Priapism is defined as a prolonged and persistent penile erection that is unrelated to sexual interest or stimulation and lasts longer than 4 hours in duration ().Three main types of priapism have been defined: ischemic (low flow), non-ischemic (high flow), and stuttering (recurrent). On exam, key findings include an erect corpus cavernosa with a flaccid glans. Thus, the penis has three pairs of arteries: two urethral arteries that run on either side of the penile urethra in the corpus spongiosum, two cavernosal arteries, each running on the center of the corpus cavernosum, and two dorsal arteries of the penis running on either side of the dorsum of the penis between the tunica albuginea and Buck fascia, near the dorsal nerves of the penis. [11] Anticoagulants (heparin and warfarin). Used to track the information of the embedded YouTube videos on a website. The dorsal artery of the penis, the other terminal branch supplying the glans penis and prepuce. Your doctor will block the blood vessel that is causing the problem (artery embolisation). More rigorous trials are needed to prove short- and long-term effectiveness.19, Duplex sonography with pulsed Doppler analysis (with and without dynamic erection studies with vasoactive substances) and nocturnal penile tumescence (NPT) are usually performed as first-line studies. However, the penile tissues continue to receive some blood flow and oxygen. Urethral (spongiosal) artery supplying the corpora spongiosa and providing anastomoses with the dorsal artery of the penis at the glans penis Failure of the veins to close completely during an erection (veno-occlusive dysfunction) may occur in men with large venous channels that drain the corpora cavernosa, and may be studied by cavernosography.13 Evidence is accumulating in favor of ED as a vascular disorder in the majority of patients.14. 2020 Mar;125(3):288-295. doi: 10.1007/s11547-019-01113-w.
