The inferior hypogastric plexus (pelvic plexus in some texts)^[1] is a plexus of nerves that supplies the viscera of the pelvic cavity.

The inferior hypogastric plexus is a paired structure, with each situated on the side of the rectum in the male, and at the sides of the rectum and vagina in the female.

Sources

Contributions to the plexus include:

a continuation of the superior hypogastric plexus on either side, in the form of the hypogastric nerve.

sacral splanchnic nerves, which emerge from the sympathetic trunk.

pelvic splanchnic nerves (from the second, third, and fourth sacral nerves) also contribute parasympathetic efferent fibers to the plexus.

At the points of junction of these nerves small ganglia are found.

Course

From these plexuses numerous branches are distributed to the viscera of the pelvis.

They accompany the branches of the internal iliac artery.

It is the source for the middle rectal plexus, vesical plexus, prostatic plexus, and uterovaginal plexus.^[2]

Redefining the coccygeal plexus.

Woon JT, Stringer MD.Author information Department of Anatomy, Otago School of Medical Sciences, University of Otago, Dunedin, New Zealand.AbstractThe coccygeal plexus is variably described in anatomy texts and has rarely been studied despite the idiopathic nature of coccydynia in up to one-third of affected patients. The plexus was therefore investigated using a combination of microdissection and histology. The distal sacrum and coccyx in continuity with ischiococcygeus were removed en bloc from 16 embalmed cadavers (mean age 78 ± 10 years, 7 females) with no local disease. Ten specimens underwent microdissection of the coccygeal plexus and the remaining six were examined histologically after staining with hematoxylin and eosin and S100 immunohistochemistry to demonstrate nerve fibers. The coccygeal plexus is formed within ischiococcygeus from the ventral rami of S4, S5, and Co1 with a contribution (gray rami communicantes) from the sacral sympathetic trunk. It gives rise to anococcygeal nerves which pierce ischiococcygeus and the sacrospinous ligament to supply the subcutaneous tissue on the dorsal aspect of the coccyx. Some branches from the plexus pass medially anterior to the coccyx. The coccycgeal plexus is formed within ischiococcygeus rather than on its pelvic surface and appears to supply skin in the anococcygeal region. It probably also contributes to the innervation of ischiococcygeus, the sacrospinous ligament, coccygeal ligaments, and periosteum. It deserves to be considered as a potential pain generator that may be implicated in some patients with coccydynia. Clin. Anat. 27:254-260, 2014. © 2013 Wiley Periodicals, Inc.

Critical review of pelvic fractures associated with external iliac artery lesion: A series of six cases.

Pascarella R1, Del Torto M2, Politano R2, Commessatti M3, Fantasia R2, Maresca A2.Author information 1Ospedali Riuniti di, Ancona, Italy. Electronic address: raffaele.pascarella@libero.it.2Ospedali Riuniti di, Ancona, Italy.3Unità di Ortopedia e Traumatologia, Ospedale Maggiore, Bologna, Italy.AbstractINTRODUCTION: Bleeding associated with pelvic fracture mostly comes from the pre-sacral and lumbar venous plexus, or directly from the fracture site. Bleeding as a consequence of arterial lesion is less common (15-20%), and that resulting from lesion of the external iliac artery (EIA) is extremely rare. The mortality rate associated with iliac artery injury ranges from 38% to 72%. Total body CT-scan with contrast medium, angiography or packing can be performed when there is arterial injury. In some cases, embolisation can stop bleeding; however, when there is involvement of the aorta, common iliac artery or EIA, immediate surgery is mandatory. The aim of this study was to report our experience of pelvic fractures associated with EIA lesion.

Complete Primary Repair of Bladder Exstrophy Is Associated With Detrusor Underactivity Type of Neurogenic Bladder.

Mesrobian HG.Author information Department of Urology, Medical College and Children's Hospital of Wisconsin Milwaukee, WI. Electronic address: hmesrobi@mcw.edu.AbstractOBJECTIVE: To test the hypothesis that complete primary repair of bladder exstrophy (CPRE) is associated with detrussor underactivity. For this purpose, we review (1) our experience, (2) the results of the published literature as it pertains to bladder function, and (3) the known anatomic basis on which the mechanism of the observed outcome can be understood.
