Clinical implications of the superficial uterine vein pattern for the dissection of the anterior layer of the vesicouterine ligament in radical hysterectomy. J Gynecol Oncol 2024; 35:e50.

Abstract
OBJECTIVE To describe anatomic patterns of the superficial uterine vein (sUV) and assess their association with aspects of the dissection procedure of the anterior layer of the vesicouterine ligament (aVUL) by retrospectively reviewing surgical videos. METHODS We analyzed patients who underwent laparoscopic radical hysterectomy for early-stage cervical cancer from 2014 to 2019. The primary endpoint was the time required for aVUL dissection. Multiple linear regression analyses were performed to identify factors influencing the time required for aVUL dissection. RESULTS Fifty-three Japanese patients were included. Two sUV configurations were observed: type 1 (the vein ran ventral to the ureter along the uterine artery) and type 2 (the vein did not run along the usual ventral course; it ran dorsal to the ureter or was absent). Approximately 30% of the sUVs were type 2. The total time for dissection of both sides of the aVUL was significantly shorter for type 2 sUVs than for type 1 sUVs. The number of hemostatic interventions during dissection of each side of the aVUL was significantly lower for type 2 sUVs than for type 1 sUVs. In the multivariate analysis, the sUV configuration was the factor significantly influencing the duration of aVUL dissection on each side (right side: β=-143.4; left side, β=-160.4). CONCLUSION We demonstrated that the sUV had 2 types of courses, ventral and others, and its course affected the time required for dissection and the number of hemostatic interventions. Our results provide information supportive of improved radical hysterectomy outcomes.

Abstract
Background The inferior hypogastric plexus (IHP) is a crucial structure for female continence and sexual function. A nerve-sparing approach should be pursued to reduce the risk of pelvic plexus damage during retroperitoneal pelvic surgery. Objectives To analyse the relationship between the female IHP and several pelvic anatomical landmarks. Materials and Methods Standardised cadaveric dissection was performed on 5 nulliparous female cadavers. The relationships of the IHP and the mid-cervical plane (MCP), the mid-sagittal plane (MSP), and the uterosacral ligament (USL) were investigated. Main outcome measures Distance between IHP and MCP, MSP, and USL. Results Distances between the right IHP and the right MSP (mean distance: 16.3 mm; range: 10.0-22.5 mm) and the right USL (mean distance: 4.8 mm; range: 0-15.0 mm) were shorter than those between the left IHP and ipsilateral landmarks (left MSP distance: 23.5 mm; range 18.0-30.0 mm; left USL distance: 5.0 mm; range: 0-20.0 mm). Although the MCP was 3.3 mm (range: 2.5-4.0 mm) left and lateral to the midsagittal line, the right IHP was closer to the MCP (mean distance: 19.6 mm; range: 13.0-25.0 mm) than the left one (mean distance: 20.2 mm; range: 15.0-26.0 mm). Conclusions Distances between the right IHP and the MSP, MCP, and ipsilateral USL, are shorter compared to these associated to the left IHP. What is new? Right autonomic pelvic plexus is closer to the midline planes and the ipsilateral USL. These anatomical relationships may be greatly helpful for pelvic surgeon while facing retroperitoneal pelvic surgery and looking for a nerve-sparing approach.

Advanced Insights into Human Uterine Innervation: Implications for Endometriosis and Pelvic Pain. J Clin Med 2024; 13:1433.

Abstract
(1) Background: Understanding uterine innervation, an essential aspect of female reproductive biology, has often been overlooked. Nevertheless, the complex architecture of uterine innervation plays a significant role in conditions such as endometriosis. Recently, advances in histological techniques have provided unprecedented details about uterine innervation, highlighting its intricate structure, distribution, and density. The intricate nature of uterine innervation and its influence on pathologies such as endometriosis has garnered increasing attention. (2) Objectives: This review aims to compile, analyze, and summarize the existing research on uterine innervation, and investigate its implications for the pathogenesis of endometriosis and associated pain. (3) Methods: A systematic review was conducted in line with PRISMA guidelines. Using the PubMed database, we searched relevant keywords such as "uterine innervation", "endometriosis", and "pain association". (4) Results: The initial literature search yielded a total of 3300 potential studies. Of these, 45 studies met our inclusion criteria and were included in the final review. The analyzed studies consistently demonstrated that the majority of studies focused on macroscopic dissection of uterine innervation for surgical purposes. Fewer studies focused on micro-innervation for uterine innervation. For endometriosis, few studies focused on neural pain pathways whereas many studies underlined an increase in nerve fiber density within ectopic endometrial tissue. This heightened innervation is suggested as a key contributor to the chronic pain experienced by endometriosis patients. (5) Conclusions: The understanding of uterine innervation, and its alterations in endometriosis, offer promising avenues for research and potential treatment.

Surg Radiol Anat 2024; 46:381-390.

Abstract
PURPOSE Pelvic gynecological surgeries, whether for malignant or benign conditions, frequently result in functional complications due to injuries to the autonomic nervous system. Recognizing the deep uterine vein (DUV) as an essential anatomical reference can aid in preserving these structures. Despite its significance, the DUV is infrequently studied and lacks comprehensive documentation in Terminologia Anatomica. This research endeavors to elucidate a detailed characterization of the DUV. METHODS We undertook a systematic literature review aligning with the "PRISMA" guidelines, sourcing from PUBMED and EMBASE. Our comprehensive anatomical examination encompassed cadaveric dissections and radio-anatomical evaluations utilizing the Anatomage® Table. RESULTS The literary exploration revealed a consensus on the DUV's description based on both anatomical and surgical observations. It arises from the merger of cervical, vesical, and vaginal veins, coursing through the paracervix in a descending and rearward direction before culminating in the internal iliac vein. The hands-on anatomical study further delineated the DUV's associations throughout its course, highlighting its role in bifurcating the uterus's lateral aspect into two distinct zones: a superior vascular zone housing the uterine artery and ureter and an inferior nervous segment below the DUV representing the autonomic nerve pathway. CONCLUSION A profound understanding of the subperitoneal space anatomy is paramount for pelvic surgeons to mitigate postoperative complications. The DUV's intricate neurovascular interplays underscore its significance as an indispensable surgical guide for safeguarding nerves and the ureter.
