This study aims to elucidate and expand current knowledge of the uterosacral ligament (USL) from a surgical viewpoint.
Studies were performed on 12 unembalmed cadaveric pelves and five formalin-fixed pelves.
The USL, 12-14-cm long, can be subdivided into three sections: (1) distal (2-3 cm), intermediate (5 cm), and proximal (5-6 cm). The thick (5-20 mm) distal section, attached to cervix and upper vagina, is confluent laterally with the cardinal ligament. The proximal section is diffuse in attachment and generally thinner. The relatively unattached intermediate section is wide, and thick, well defined when placed under tension, more than 2 cm from the ureter and suitable for surgical use. The strength of the USL is perhaps derived not only from the ligament itself, but also from the addition of extraperitoneal connective tissue.
The USL can be subdivided into three sections according to thickness and attachments with the intermediate section suitable for surgical use, particularly for vaginal vault support.
本研究旨在从外科手术角度阐明并拓展目前关于子宫骶韧带（USL）的知识。
对12具未防腐处理的尸体骨盆和5具经福尔马林固定的骨盆进行研究。
子宫骶韧带长12 - 14厘米，可分为三个部分：（1）远端（2 - 3厘米）、中间段（5厘米）和近端（5 - 6厘米）。较厚（5 - 20毫米）的远端部分附着于宫颈和阴道上段，在外侧与主韧带相连。近端部分附着疏松，通常较薄。相对游离的中间段较宽且厚，在张力作用下边界清晰，距输尿管超过2厘米，适合手术使用。子宫骶韧带的强度可能不仅源于韧带本身，还源于腹膜外结缔组织的添加。
子宫骶韧带可根据厚度和附着情况分为三个部分，其中间段适合手术使用，尤其适用于阴道穹窿支撑。
