AIMS: To characterize the nature and function of the levator ani muscle innervation pathways and to perform a comprehensive three-dimensional reconstruction of female pelvic innervation. METHODS: A computer-assisted anatomical dissection protocol was applied to seven female human fetuses, after approval from the national biomedicine agency. Specimens were serially sectioned and immunostained for overall (antibody against protein S100), somatic (antibody against peripheral myelin protein 22), adrenergic (antibody against tyrosine hydroxylase), cholinergic (antibody against vesicular acetylcholine transferase), and nitrergic (antibody against the neural isoform of nitric oxide synthase) nerve fibers...

Superior hypogastric plexus (SHG) contains mainly sympathetic and most probably also postganglionic parasympathetic fibers. Thus, surgical damage of SHG may cause autonomic pelvic organ dysfunction (Kraima et al., 2015). As already shown for rectal cancer, preservation of the autonomic nerves is facilitated by robotic surgery and may avoid sexual dysfunctions and voiding disorders (Kim et al., 2015). In this educational video, we demonstrate left lower paraaortic lymph node dissection preserving the SHG using ICG fluorescence to label the lymphatic compartment...

INTRODUCTION AND HYPOTHESIS: Transvaginal ipsilateral uterosacral ligament colpopexy for pelvic organ prolapse (POP), which was reported by Shull et al. (Shull's colpopexy) in 2000, is one of the most frequently performed non-mesh pelvic floor reconstructive surgical procedures. Despite its excellent anatomical outcomes, ureteral injury and difficulty in uterosacral ligament detection (especially in patients with severe POP) are typical issues with this procedure. METHOD: This video demonstrates the procedure in a 58-year-old woman, gravida 2 para 2, with POP-Q stage II uterine prolapse and stage I cystocele...

Radical hysterectomy (RH) is an effective treatment for early-stage cervical cancer IA2 to IIA1 but RH is often associated with several significant complications such as urinary, anorectal and sexual dysfunction due to pelvic nerve injuries. Pelvic autonomic nerves including the superior hypogastric plexus (SHP), hypogastric nerves (HN), pelvic splanchnic nerves (PSN), sacral splanchnic nerves (SSN), inferior hypogastric plexus (IHP) and efferent branches of the IHP. We aimed to precise the neuroanatomy of the female pelvis in order to provide key-points of surgical anatomy to improve NSRH for cervical cancer...

OBJECTIVES: Deep pelvic endometriosis surgery may need substantial excisions, which in turn expose to risks of injury to the pelvic nerves. To limit functional complications, nerve-sparing surgical techniques have been developed but should be adapted to the specific multifocal character of endometriotic lesions. The objective was to identify the anatomical areas where the pelvic nerves are most at risk of injury during endometriotic excisions. METHODS: The Medline and Embase databases have been searched for available literature using the keywords "hypogastric nerve or hypogastric plexus [Mesh] or autonomic pathway [Mesh], anatomy, endometriosis, surgery [Mesh]"...

OBJECTIVE: Radical hysterectomy with pelvic lymphadenectomy (RHL) is the preferred treatment for early-stage cervical cancer. Although oncological outcome is good with regard to recurrence and survival rates, it is well known that RHL might result in postoperative bladder impairments due to autonomic nerve disruption. The pelvic autonomic network has been extensively studied, but the anatomy of nerve fibers branching off the inferior hypogastric plexus to innervate the bladder is less known...

INTRODUCTION: In the pelvis, the rectogenital septum (RGS) separates the urogenital compartment from the digestive compartment. In men, it corresponds to Denonvilliers' rectoprostatic fascia or rectovesical septum (RVS). Its purpose-and, indeed, its existence-are controversial in women. The purpose of this review was to update knowledge about the RGS in women and, in particular, to clarify its relationship to pelvic nerves in order to deduce practical consequences of pelvic surgery and compare it to the RVS in men...

Pelvic autonomic nerve is a three-dimensional structure surrounding the rectum. There are several key points related to nerve injury during laparoscopic radical resection for rectal cancer. Hypogastric nerve has close relation with the upper and middle part of the rectum. Combined with S2-S4 pelvic splanchnic nerve, hypogastric nerve forms pelvic plexus. Incorrect operation in pelvic parietal peritoneum during dissection of upper rectum will lead to nerve injury. When performing dissection of inferior mesenteric artery, bilateral nerve tracts should be pushed to posterior abdominal wall and anterior fascia of the abdominal aorta should be well protected to avoid nerve injury...

BACKGROUND: Cervical cancer is the second most common malignancy of the female genital tract worldwide. Radical hysterectomy with pelvic lymphadenectomy exemplifies the treatment of choice for early stage disease, whereas even if it is performed by gynaecologist-oncologist, still has the drawback of significant postoperative morbidity, especially for urinary bladder function. Nerve-sparing radical hysterectomy (NSRH) is a technique in which the neural part of the cardinal ligament which encloses the inferior hypogastric plexus, as well as the bladder branch (distal part of the plexus), remains intact...

BACKGROUND: The superior hypogastric plexus (SHGP) carries afferents from the viscera of the lower abdomen and pelvis. Neurolytic block of this plexus is used for reducing pain resulting from malignancy in these organs. The ganglion impar (GI) innervats the perineum, distal rectum, anus, distal urethra, vulva, and distal third of the vagina. Different approaches to the ganglion impar neurolysis have been described in the literature. OBJECTIVES: To assess the feasibility, safety, and efficacy of combining the block of the SHGP through the postero-median transdiscal approach with the GI block by the trans-sacro-coccygeal approach for relief of pelvic and/or perineal pain caused by pelvic and/or perineal malignancies or any cancer related causes...

We herein report a case of laparoscopic high anterior resection with D3 lymph node dissection for rectosigmoid colon cancer with a horseshoe kidney. A 65-year-old Japanese man referred to our hospital for rectosigmoid colon cancer was found to have a horseshoe kidney on a CT scan. On 3-D CT angiography, an aberrant renal artery was visualized feeding the renal isthmus that arises from the aorta just below the root of the inferior mesenteric artery (IMA). Laparoscopic anterior rectal resection with D3 lymph node dissection was performed...

BACKGROUND: Urogenital dysfunctions are well-recognized problems after rectal cancer surgery and are often due to autonomic nerve damage. Although following holy planes during total mesorectal excision (TME) reduces the possibility of damage to the autonomic nerve fibers, these could still be affected in some critical areas.1 (,) 2 To improve the quality of surgery and prevent nerve damage, accurate intraoperative anatomical orientation of autonomic nerve is essential.3 Thanks to advancement of the high-definition laparoscopic technology, even the finest nerve fibers deep in the pelvic cavity can be identified through illumination and magnification...
