Penile ultrasonically with Doppler can be used to examine the penis in erected state. Most cases of ED of organic causes are related to changes in blood flow in the corpora cavernous, represented by occlusive artery disease, most often of atherosclerotic origin, or due to failure of the venom-occlusive mechanism. Preceding the ultrasound examination with Doppler, the penis should be examined in B mode, in order to identify possible tumors, fibroid plaques, calcification, or anathemas, as well as to evaluate the appearance of the cavernous arteries, which can be tortuous or aromatherapist.
Erection can be induced by injecting 10-20 µg of propagandist E1, with evaluations of the arterial flow every five minutes for 25-30 min (see image). The use of propagandist E1 is contraindicated in patients with a predisposition to prism (e.g., those with sickle cell anemia), as well as in those with an anatomical deformity of the penis or a penile implant. Amphetamine (2 mg) is often added. Visual and tactile stimulation produces better results. Some authors recommend the use of sildenafil by mouth to replace the inject able drugs in cases of contraindications, although the efficacy of such medication is controversial......continue press https://bitbin.it/EAdxwG86/
