puborectalis

The puborectalis muscle is one of the pelvic floor muscles.

Puborectalis and pubococcygeus are folded and held with stitches.

Many people with FI have a generalized weakness of the pelvic floor, especially puborectalis.

Puborectalis is part of the levator ani muscle.

These include the entry muscle (bulbocavernosum) and the mid-vaginal muscle (puborectalis).

Biofeedback is a major treatment for anismus (paradoxical contraction of puborectalis during defecation).

Historically, the standard treatment was surgical resection of the puborectalis muscle, which sometimes resulted in fecal incontinence.

For example, the patient may not be able to relax under the conditions, leading to relaxation failure of puborectalis and false positive diagnosis of anismus.

Obstructed defecation is often due to anismus (paradoxical contraction or relaxation failure of the puborectalis).

The puborectalis originates on the posterior aspect of the pubic bone, and runs backwards, looping around the bowel.

The puborectalis sling, forming the anorectal angle (see diagram), is responsible for gross continence of solid stool.

Malfunction (a focal dystonia) of the external anal sphincter and puborectalis muscle during defecation". "

Some authors have commented that the "puborectalis paradox" and "spastic pelvic floor" concepts have no objective data to support their validity.

More effort is required because of concomitant anismus, or non-relaxation/paradoxical contraction of puborectalis (which should normally relax during defecation).

Lastly, a line from the pubic symphysis to the puborectalis muscle sling is drawn, which is a measurement of the pelvic floor hiatus.

Digital rectal examination is performed to assesses resting pressure and voluntary contraction (maximum squeeze) of the sphincter complex and puborectalis.

Injections of botulin toxin type-A into the puborectalis muscle are very effective in the short term, and somewhat effective in the long term.

It terminates at the level of the anorectal ring (the level of the puborectalis sling) or the dentate line, again depending upon which definition is used.

It is now known that the components of levator ani (the pelvic diaphragm), namely pubococcygeus, puborectalis and ileococcygeus, contract and relax as one muscle.

There was definite evidence of Paradoxical Puborectalis contraction on the EMG and on Cine-defaecography (double contrast).

After this, the location of the puborectalis muscle sling is assessed, and a perpendicular line between the pubococcygeal line and muscle sling is drawn.

It is formed from three muscle components: the puborectalis, the pubococcygeus muscle (of which the puborectalis is part of) and the iliococcygeus muscle.
