To investigate the feasibility of identifying and measuring the normal sacral plexus (SP) on gynecological transvaginal ultrasound (TVS) examination.
This was a prospective observational study conducted at a single tertiary gynecological referral center, including consecutive women undergoing TVS for various indications between November 2021 and January 2022. A standardized assessment of the pelvic organs was performed and the presence of any congenital or acquired uterine pathology or ovarian abnormality was recorded. Visualization of the right and left SP was attempted in all cases. The success rate and the time needed to identify the SP were recorded and measurements of the SP were made.
A total of 326 patients were included in the study. In all women, the SP was identified successfully on at least one side. SP were visualized bilaterally in 317 (97.2% (95% CI, 94.4-98.5%)) women. Only the right SP was seen in 3/326 (0.9% (95% CI, 0.2-2.7%)) and only the left in 6/326 (1.8% (95% CI, 0.6-4.0%)) (P = 0.5048). There was no significant difference in the median time required to visualize the right vs left SP (9.0 (interquartile range (IQR), 8.0-10.0) s vs 9.0 (IQR, 8.0-10.0) s; P = 0.0770). The median transverse diameter of the right SP was 15.0 (IQR, 14.2-15.6) mm and that of the left SP was 14.9 (IQR, 14.4-15.6) mm.
We describe a novel method which allows for the consistent and rapid identification of the SP on TVS. Integrating assessment of the SP into routine pelvic TVS may be helpful particularly for women suffering from deep endometriosis. © 2023 The Authors.

探讨在妇科经阴道超声（TVS）检查中识别和测量正常骶丛（SP）的可行性。
这是一项在一家单中心三级妇科转诊中心进行的前瞻性观察性研究，纳入 2021 年 11 月至 2022 年 1 月期间因各种原因接受 TVS 检查的连续女性。对盆腔器官进行标准化评估，并记录任何先天性或获得性子宫病理学或卵巢异常的存在。所有病例均尝试显示右侧和左侧 SP。记录识别 SP 的成功率和所需时间，并测量 SP。
共有 326 名患者纳入研究。所有女性至少在一侧成功识别出 SP。317 名（97.2%（95%置信区间，94.4-98.5%））女性双侧显示 SP。仅在 3/326（0.9%（95%置信区间，0.2-2.7%））名女性中仅可见右侧 SP，仅在 6/326（1.8%（95%置信区间，0.6-4.0%））名女性中仅可见左侧 SP（P=0.5048）。右侧和左侧 SP 显示所需的中位数时间无显著差异（9.0（四分位距（IQR），8.0-10.0）s vs 9.0（IQR，8.0-10.0）s；P=0.0770）。右侧 SP 的横向直径中位数为 15.0（IQR，14.2-15.6）mm，左侧 SP 为 14.9（IQR，14.4-15.6）mm。
我们描述了一种新的方法，可在 TVS 上稳定快速地识别 SP。将 SP 的评估纳入常规盆腔 TVS 可能特别有助于患有深部子宫内膜异位症的女性。© 2023 作者。超声在妇产科由 John Wiley & Sons Ltd 代表国际妇产科超声学会出版。
