We believe that the damage to the perineal body, superficial transverse perineal muscles, and bulbospongiosus
muscles, which provide contribution to anal continence, is ignored, especially in direct surgical repair.
Anatomically, in women, the perineal body separates the anal canal from the urogenital diaphragm in the median plane where the deep bulbospongiosus
and superficial transverse perineal muscles meet the external anal sphincter (EAS).
The incision extends through skin, retractor penis and bulbospongiosus
muscles, CSP, and urethral mucosa to expose the lumen of the urethra.
A longitudinal incision was made in the perineum, the urethra was palpated and noted to be indurated and firm, and thus the bulbospongiosus
muscle was split and a longitudinal incision was made in Buck's fascia with expulsion of approximately 10 ml of purulent fluid which was sent for culture and gram stain.
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.
