sling elevates the bladder neck and combines with the striated muscles to increase urethral closure pressure whenever intra-abdominal pressure increases.
A horizontal dissection was made on the perineum, levator ani muscle was held from bilateral pararectal region, and perineoplasty was performed by enhancing puborectal
muscle (levator ani) medial part fixation.
La accion del loop permite llevar el ano en sentido posterior, oponiendose a los movimientos del musculo puborectal
cuando este no esta danado.
La continencia fecal considerada como la habilidad corporal para reconocer cuando la ampolla rectal esta llena, depende del esfinter anal externo, el musculo puborectal
, el esfinter anal interno y el recto.
The lesions are divided into high and low types, based on whether the rectum ends above or below the puborectal
component of the levator ani complex.
The puborectal sling usually produces an angle of about 90 [degrees] between the rectal ampulla and the anal canal, so it is closed off.
This angle is primarily the result of the action of the puborectal muscles pulling on the rectum anteriorly.
A flap of anterior rectal mucosa that lies over the upper end of the anal canal is thought to function as a flap-valve, opening when the puborectal muscle relaxes so that the anorectal angle is obliterated, permitting defecation to occur.
