Anatomical study on bladder functional reconstruction with Achilles tendon reflex / 中国组织工程研究

ABSTRACT

BACKGROUND: In recent years, the method of bladder reconstruction is still at the experimental stage. Therefore, anatomical study is necessary for its clinical application.OBJECTIVE: To provide anatomical bases for the selection of proper spinal roots, the ideal level for cross anastomosis, and the identification of anterior roots of spinal nerves during bladder functional reconstruction with Achilles tendon reflexes.DESIGN: It was a single sample study with anatomical specimen as subjects.SETTING: The experiment was conducted in the department of orthopaedics of a municipal hospital.PARTICIPANTS: The experiment was completed in the Department of Anatomy, Second Military Medical University of Chinese PLA, from May 1999 to January 2000. Altogether 20 adult corpse specimens (14 males and 6females, 40 sides) were involved.INTERVENTION The origin of spinal roots of the sacral plexus and sciatic nerve, the distribution of corresponding spinal root between the sciatic nerve and other nerves were followed up.MAIN OUTCOME MEASURES: Overlapping length, horizontal area, and relative position of anterior roots of L4-S4 spinal nerves in the dura mater.of S2 -4 anterior spinal roots originating from the spinal cord was higher than that of L4, L5 and S1 anterior spinal roots running through the dura; the cross-sectional area of L4(2. 19 ±0.39) mm2, L5(2.58 ±0.58) mm2 and S1(2.19 ± 0.42) mm2 anterior spinal roots was more than that of S2-4 anterior dentify their sequence at the terminal cone level than under this level.should be taken during bladder functional reconstruction with Achilles tendon level.
