Pelvic floor and pelvic diaphragm surgery
In women, similar to men, but with the vagina passing, separating the spongy muscle and this muscle becomes the vaginal muscle, and at the same time weakens a lot of the deep pelvic transverse muscles.

The bottom of the pelvis is the lower wall of the abdominal cavity.
The front is the pubic joint.
Behind is the coccyx.
The two sides are seat mounds.
The edges are:
In front is the mundane industry.
Behind are the ligament and seated mound.
A straight line connecting the two seated mounds divided the upper quadrilateral into two parts: The first part is called the urinary triangle; the second part is called the anus triangle.
The urinary triangle (men)
From shallow to deep:
The perineal macular is shallow: located on the shallow side of the erectile organs, the posterior margin is attached to the lower urinary diaphragm.
Lower urogenital diaphragm: located on the shallow side of the urinary diaphragm. The two sides on the posterior bank stick together open to the front of the limit of a space called the shallow perineal cavity containing the posterior part of the erectile organs, the spongy muscle, the cavernous muscle, the shallow perineal transverse muscle, the blood vessels, the scrotum.

Deep pelvic cavity: composed mainly of the urinary diaphragm, where the upper and lower surfaces are covered by the upper and lower urinary diaphragm consisting of two muscles:
Sphincter of the urethra: primitive in the sub-pubic branch, sticking in the midline.
Deep pelvic transverse muscle: originating from the sitting bone branch, sticking to the centre of the perineal tendon, in this muscle, there is the urethral gland.
In women, similar to men, but with the vagina passing, separating the spongy muscle and this muscle becomes the vaginal muscle, and at the same time weakens a lot of the deep pelvic transverse muscles. The porous ganglia become the vestibule below the vaginal wall that is an erectile organ and the urethral gland becomes the large vestibular gland.
Perineal tendon centre
Located at the midpoint of the anorectal line, most of the muscles clinging here are considered the key to opening the perineum, especially important in women who are responsible for indirect support of the uterus, or damage. injury at birth.
There is a muscle that is the sphincter of the anus consisting of three parts:
The deep part is wrapped around the upper part of the anal canal.
The middle part goes from the coccyx, wrapping the sides of the anal canal to attach to the centre of the perineum tendon.
The lower part goes around the anal hole.
Rectal hole: On a vertical triangular set. The bottom is the skin, the inner wall is the anal lift muscle, the outer wall is the inner muscle and the muscular mucosa is plugged in, the back is connected to the other hole behind the anus, in front of there is a niche between the urogenital diaphragm and the posterior lift subject. In the pit contains blood vessels, lower rectal nerve, fat so it is very infected.
The deepest layer has two muscles, the anal lift and amputee.
Anal lift muscles
Creates a muscle floor in the perineum, through which there are holes for the urethra, anus, and vagina in women to pass through. This muscle is divided into 3 parts: pubic rectum, pubic part, pelvic part.
It could be a muscle or a tendon that stretches from the sitting bone to the coccyx and sacrum.
