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. 2011 May;41(5):627-32. doi: 10.1007/s00247-010-1912-3. Treatment for priapism will depend on the type you have. Nitric oxide causes smooth muscle relaxation, which leads to arterial influx of blood into the corpus cavernosum, followed by compression of venous return, producing an erection. Generalized penile arterial insufficiency may result from stenotic arterial lesions of the internal pudendal arteries or from microangiopathy of the arteries of the corpora cavernosa. 2008 Jan;5(1):173-9. doi: 10.1111/j.1743-6109.2007.00560.x.

PMC Evaluation of these vasculogenic factors ultimately depends on cavernosography and internal pudendal angiography. 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.26 The priapism types are: Low-flow or ischemic priapism; High-flow or non-ischemic priapism; Ischemic Priapism. The treatment of priapism will differ depending on the diagnosis of these two different types. Make a donation. For treatment of an acute major ischemic priapism episode, a 16 or 18 gauge needle is inserted into the corpus cavernosum to aspirate blood, irrigate with saline, and inject sympathomimetics as necessary.
