One case was a retroperitoneal pelvic schwannoma located in the right paracolpium
,  and another was a schwannoma present at the L5 vertebral body and causing pelvic pain.
The upper third of the vagina (level I) is suspended from the pelvic walls by vertical fibers of the paracolpium
, which is a continuation of the cardinal ligament.
The clamp should now include the superior portion of the cardinal ligament with the uterine vessels and paracolpium
immediately above the lateral vaginal fornix.
An incision is made around the cervix, the paracolpium
is divided, and the blood supply is divided, creating a bloodless organ, he said.
