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 muscle.
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.

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.
