The ligamentous mesometrium is a 3-dimensional structure consisting of a rectouterine/-vaginal part with attachment to the anterior lateral mesorectum and a sacrouterine part surrounding the mesorectum attached to the pelvic fascia and the mesorectum dorsolaterally. The lymphatic network draining the posterior cervix connected caudally ventrally to the deep venous lymph network of the vascular mesometrium is running at the lateral surface of the sacrouterine part and dorsomedially of the inferior hypogastric plexus; it drains to the deep internal iliac, prespinal and preischiadic nodes.
