Dissection of the cardinal ligament in radical hysterectomy for cervical cancer with emphasis on the lateral ligament

Surgical experience with carcinomas of the uterus and rectum has provided new insights into the surgical anatomy of a lamina, which separates the paravesical space from the pararectal space. It has been proved that each of the lamina consists of the cardinal and lateral ligaments and pelvic splanchnic nerves, descending in the following order. The cardinal and lateral ligaments, as a connective stalk, insert into the lateral walls of the uterus and rectum extending from the inner aspect of the pelvic wall. Clarification of this structural relationship led to the development of a new procedure for the dissection of the cardinal ligament in radical hysterectomy, while still preserving the lateral ligament. This facilitated systematic dissection of the cardinal and uterosacral ligaments with posterior manipulation, leading to a reduction in blood loss and to prevention of brisk bleeding from the venous plexuses.
