This video shows a reproducible approach to complete parametrectomy in a patient who had had a hysterectomy. The procedure begins with adhesiolysis and dissection of the lateral pelvic spaces in order to identify and isolate the parametrium. The paravesical fossa is then dissected medially and laterally using the umbilical artery as a landmark. The surgeon identifies the uterine artery and parametrium by following the umbilical artery. Using the uterine artery as a landmark of the parametrium, dissection is continued posteriorly developing the pararectal spaces in order to isolate the posterior part of the parametrium. The ureter is dissected towards the ureteral channel and unroofed. The procedure is carried on with the complete isolation of the ureter in its anterior aspect between the parametrium and the bladder. The bladder pillar is then transected at the level of the bladder. The rectal pillar is transected at the level of the rectum, paying attention to isolate the inferior hypogastric nerve. The parametrium is then cut at the level of the hypogastric vessel. The vagina is cut with ultrasonic scissors using a cap of RUMI II as a guide, and the specimen is extracted vaginally. The surgeon performs a bilateral lymphadenectomy. In this step, the obturator nerve is dissected to prevent injuries at the medial aspect of the obturator artery. The vagina is closed with continued stitches vaginally using an extracorporeal knotting technique.
