Two forms of the lateral parametrium. A denotes a P&A and Netter’ schematic illustration of the descriptive form of post-deformation of LP. The ventral aspect of LP, which horizontally connects the lateral aspect of the uterus and pelvic sidewall, is exposed by an incision to the anterior leaf of the broad ligament and mobilization of the bladder. This was followed by creation of the pararectal space by excision of areolar connective tissue along the dorsal aspect of LP. B is a modified version of a schematic illustration in an article by Yabuki, et al., 1996; 62: 370-8 showing a practical form of post-deformation of LP. Spontaneous and perpendicular excavation of the pararectal space takes place on the lateral aspect to the ureter. Perpendicular excavation of the paravesical space is also carried out, though it is not depicted. The relationship between the uterus and LP is perpendicular. a; uterus, b; bladder, c; rectum, d; uterine cervix, e; vagina, f; ureter, g; uterine artery, h; deep uterine vein, i; ascending branch of the uterine vessels, j; descending branch of the uterine vessels, k; vesicohypogastric fascia, l; TCL, m; lateral ligament of the rectum, n; Latzko’s pararectal space (upper portion), o; common iliac vessels, p; internal iliac vessels, w; paracolpium.
