Figure 2: Data obtained during dual cavernosography. A). The cavernosograms was taken while Omnipaque solution profuse the corpora cavernosa (asterisk) via a #19 scalp needle (white arrow). This film shows the deep dorsal vein (black arrow) as well as the cavernosal vein (masked). B). After the intracavernous injection of 20μg prostaglandin E1 (test), a pharmacocavernosogram demonstrates veno-occlusive dysfunction (VOD) because the leaky veins (black arrows) still present. The ventral curvature is remarked. C). This film was obtained after surgery with the similar condition as that in panel A. Note the sinusoids (asterisk) was obviously improved in fluid retention. D). Similarly it is for comparison with panel B. Note no more leaky veins and penile dysmorphology. Thus an ideal penile shape is there.
