ABSTRACT

The cranial part of the compartment is located intraperitoneally, consisting of the Fallopian tubes, mesosalpinx, uterine corpus, and broad ligament. The retro-and subperitoneal caudal part is represented by the cervix, the vagina (except its distal part), and enveloping mesotissue, designated as mesometrium. The mesometrium tapers off with bilateral wings made up of dorsolaterally directed supply tissue with the uterine and vaginal arteries and veins, lymphatic drainage and a few lymph nodes (termed “vascular mesometrium”), and dorsally directed suspensory and fatty tissue fused to the anterior and lateral mesorectum (termed “ligamentous mesometrium”). The vascular mesometrium is adherent to the bladder and its mesentery anterolaterally and is traversed by the ureters. The ligamentous mesometrium is a semi-cylindrical tissue sheet attached to the mesorectum following the pelvic curvature sagittally. It is composed of parts of the posterior broad ligaments, uterosacral ligaments, the rectouterine and rectovaginal ligaments, and the rectovaginal septum. Laterally, the plexus hypogastricus inferior adheres to the ligamentous mesometrium. Dorsally and inferiorly it is continuous with the endopelvic fascia of the pelvic wall and floor. The subperitoneal part of the Müllerian compartment is a distinct arterialcapillary territory covered by continuous lamellae. Venous drainage of the uterovaginal compartment is connected to the lower urinary tract. The deep uterine and vaginal veins fuse with the bladder veins.
