Imaging which may be used to detect cul-de-sac hernia includes standard defecography, magnetic resonance defecography and dynamic transperineal ultrasound. [5] Cul-de-sac hernias usually only appear on such imagining at the end of the simulated defecation, and require complete or near complete evacuation of the rectum before they are visible. [3]
In women, the rectouterine pouch is the deepest point of the peritoneal cavity. It is posterior to the uterus, and anterior to the rectum. [2] Its anterior boundary is formed by the posterior fornix of the vagina. [1] The pouch on the other side of the uterus near to the anterior fornix is the vesicouterine pouch.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Culdoscopy is an endoscopic procedure performed to examine the rectouterine pouch and pelvic viscera by the introduction of a culdoscope through the posterior vaginal wall. [1] The word culdoscopy (and culdoscope) is derived from the term cul-de-sac, which means literally in French "bottom of a sac", and refers to the rectouterine pouch (or called the pouch of Douglas).
The thecal sac or dural sac is the membranous sheath (theca) or tube of dura mater that surrounds the spinal cord and the cauda equina. The thecal sac contains the cerebrospinal fluid which provides nutrients and buoyancy to the spinal cord. [ 1 ]
The term cecum comes from Latin (intestinum) caecum, literally 'blind intestine', in the sense 'blind gut' or 'cul de sac'. [6] It is a direct translation from Ancient Greek τυφλὸν (ἔντερον) typhlòn (énteron). Thus the inflammation of the cecum is called typhlitis.
A transvaginal ultrasound showing a retroverted uterus during pregnancy. The cervix lies posteriorly to the urinary bladder, and the uterus normally extends superiorly from it, but the direction of the body of the fetus reveals that the uterus extends backwards. Specialty: Gynaecology: Treatment: Exercise.
Persistent lumbar multifidus dysfunction is diagnosed by atrophic replacement of the multifidus with fat, as visualized by magnetic resonance imaging or ultrasound. [ 1 ] [ 2 ] One way to help recruit and strengthen the lumbar multifidus muscles is by tensing the pelvic floor muscles for a few seconds "as if stopping urination midstream".
