Penile revascularization is a specialized vascular-surgical treatment option for erectile dysfunction. The 2009 International Consultation on Sexual Dysfunctions recommended that revascularization be limited to nonsmoker, nondiabetic men younger than 55 years of age with isolated stenosis of the internal pudendal artery with absence of venous leak.

Penile plethysmography (PPG) or phallometry is a measurement of blood flow to the penis, typically used as a proxy for measurement of sexual arousal.The most commonly reported methods of conducting penile plethysmography involves the measurement of the circumference of the penis with a mercury-in-rubber or electromechanical strain gauge, or the volume of the penis with an airtight cylinder and ...
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.
Symptoms may begin quickly or slowly depending on the size of the embolus and how much it blocks the blood flow. [2] Symptoms of embolisation in an organ vary with the organ involved but commonly include: Pain in the involved body part [2] Temporarily [2] decreased organ function; Later symptoms are closely related to infarction of the affected ...
Other symptoms include severe pain, loss of erection, and swelling. [5] Symptoms of urethral injury include hematuria, blood at the meatus, and dysuria. [1] If left untreated, complications result in 28–53% of cases; these include permanent curvature of the penis, fistula, urethral diverticulum, priapism, and erectile dysfunction. [5]
On entering the cavernous structure from the deep artery of the penis the arteries divide into branches, which are supported and enclosed by the trabeculae.Some of these arteries end in a capillary net-work, the branches of which open directly into the cavernous spaces; others assume a tendril-like appearance, and form convoluted and somewhat dilated vessels, which were named by Rosenmüller ...
When a large amount of blood flows to the genital region, the penis becomes erect and the testicles also experience increased blood flow and swelling. [4] In the vulva, the blood flow increases in erectile tissue, causing it to expand. After orgasm, the tissue shrinks back to its initial size as most of the blood leaves.
