Objectives: Radical hysterectomy is performed for invasive cervical cancer. In this surgery, separation of the anterior leaf and posterior leaves of the vesicouterine ligament (VUL) is important. We studied the local anatomy of the anterior leaf of the VUL, especially the branches of the umbilical artery from the view point of surgery and cadaver dissection. Study Design: We observed the cervicovesical blood vessels and the connective tissue layer continued from umbilical artery and searched for the origin of the cervicovesical blood vessels in radical hysterectomy. We also dissected a formalin-fixed female cadaver, and observed the same points. Results: After separation of the connective tissue of urinary bladder from the cervical fascia, we could discern the outline of the distal ureter near the ureterovesical junction. We separate the connective tissue of the so-called anterior leaf of the VUL enwrapping the ureter gently, and then the ureter with the connective tissue is completely rolled out laterally. We identified a cervicovesical vessel crossing over the ureter. We looked for the central side of the cervicovesical vessel and found that cervicovesical vessel was a branch of the superior vesical artery. And, during cadaver dissection, we found that the connective tissue and the branches of the superior vesical artery were similarly observed. Conclusions: We found the precise anatomy of the connective tissue layer from umbilical artery to urinary bladder and the superior vesical artery. Our procedure based on the precise anatomy obtained in this study is reasonable anatomically as a method for separation of the vesicouterine ligament during radical hysterectomy.
