In patients who have undergone a hysterectomy, the superior border extendes to include the topmost slice where the vaginal vault is visible and includes portions of the vascular pedicle at the superior aspect of the vaginal vault.

Lateral Boundary
Covers the external contour of the vagina but excluding the pelvic floor muscles
Ventral Boundary
Upto the urethra
