Anterior Compartment Including Ureter
Endometriosis is usually classified into three main forms: ovarian, superficial, and deep infiltrating endometriosis (DIE). The latter is the most severe type of endometriosis and is defined as the presence of endometrial glands and stroma infiltrating a depth of >5 mm beneath the peritoneum [1, 2]. Implants of endometriosis may be supplied by the nerves and lymphatic and blood vessels and are surrounded by a variable amount of collagen fibers and elastin. Infiltration of the urinary tract occurs in approximately 1–2% of patients with endometriosis , but its prevalence increases to 19–53% among patients with severe endometriosis, as for those with DIE [4–6].
Normal anterior pelvic compartment. Note the sliding of the bladder and uterus. The bladder wall has normal shape and morphology (AVI 4329 kb)
Normal posterior pelvic compartment. Note the sliding of the rectum and uterus. The vaginal wall, uterosacral ligaments, and anterior rectal wall appear normal and the sliding sign is positive (AVI 8139 kb)
