Objective: The authors revised the surgical procedure for radical hysterectomy utilizing detailed observation of the venous system, connective fascial sheets, and neural pathways within the uterine supports.
Study design: The anterior, middle, and posterior uterine supports were reclassified into two systems, supporting or fascial and drainage or areoral. Supporting system consisted of the superficial layer of the vesicouterine ligament, fascial part of the Mackenrodt ligament, sacrouterine ligament, and rectovaginal ligament, whereas drainage system consisted of the deep layer of the vesicouterine ligament, vascular part of the Mackenrodt ligament, and the so-called mesoureter. The operative procedure was planned according to the continuity of these ligaments and executed first by excising the fascia and then dissecting the denuded areoral tissue.
Results: Among the 15 patients who underwent surgery for uterine cancer during a 2-year period the mean (SD) time required for the operation was 305.5 +/- 30.5 min and the mean (SD) total volume of blood loss 592.0 +/- 238.2 ml. A mean (SD) period of 14.3 +/- 3.8 postoperative days was required until the volume of the residual urine decreased to less than 50 mL.
Conclusion: The present operation has been structured more three-dimensionally and systematically than before. Further, safety of the operation was significantly improved including prevention of hemorrhage and preservation of bladder function.
