The dissection was superior to the bulbospongiosus
The superficial pouch has structures common to both males and females, including the ischiocavernosus, bulbospongiosus
, superficial transversus perinei muscles, the pudendal vessels, and pudendal nerves.
2014) Identification of CNS neurons innervating the levator ani and ventral bulbospongiosus
muscles in male rats.
Blunt dissection of subcutis, penis retractor muscles, and bulbospongiosus
muscles was achieved until the urethra was visualized.
The bulbar urethra is segment of urethra enclosed by the bulbospongiosus
muscle and is the commonest site for a stricture.
Surgical access is traditionally obtained via a longitudinal midline perineal incision over the urethra with subsequent dissection through the bulbospongiosus
muscle, although alternative approaches have been employed as well, including the peno-scrotal and retropubic approaches.
urethra is then exposed (see Figure 4).
In most women, this incision cuts a portion of the bulbospongiosus
muscle and, occasionally, reaches the ischioanal fossa.
Blood drainage from the penis is done by external pudendal vein and internal pudendal vein and venous blood in deep vein penis, bulbar vein and dorsal penile vein enter to internal pudendal vein and then internal iliac and finally coudal vena cava, and the external pudendal vein blood prepuce, skin, corpus spongiosum penis and ischiocavernosus, bulbospongiosus
and retractor muscles and free part penis through dorsal vein drainage (Fig7,8).
