(2)Themean length of uterosacral ligamentswas6. 5cm,TheTH-positive fibers located in themedialand cephalic part of the ligaments at a distance of6. 0cmand 5. 5cm from cervix uter,i in themiddle and inferior partof the ligaments at5. 5cm, 4. 5cm, 4. 0cm, 3. 5cm, 3. 0cm, 2. 5cm and 2. 0cm, in the caudal and lateral side of the ligaments at1. 5cm, 1. 0cm and 0. 5cm. (3)Themean length ofvesicouterine ligamentswas 2. 3cm,TheTH-positive fibers located in themedial side of the vesical veins in deep layerof the
