摘要
目的 探讨泌尿外科术中避免损伤盆腔神经丛 (盆丛 )的解剖标志。方法 对 42具盆腔器官作盆腔解剖或组织切片 ,观察盆丛与盆腔脏器的毗邻关系。结果 盆丛位于直肠的前外侧 ,距肛门口 ( 9.5± 1.6)cm ,精囊的后外侧 ,在前列腺基底部与前列腺血管形成神经血管束 ,于尿道膜部外侧和后外侧 ,穿尿生殖膈。结论 精囊和前列腺神经血管束可作为泌尿外科术中防止损伤盆丛的一个标志。
Objective To study the applied anatomy of the male pelvic plexus so as to find the anatomical marker to avoid pelvic plexus injuries during urinary surgery in the pelvis. Methods Detailed anatomical dissection was performed on the pelvic organs of 42 male human cadavers. The exact relation of pelvic plexus to its adjacent organs was observed. Results The pelvic plexus was located at the anterolateral side of the rectum, (9.5±1.6) cm away from the anal verge, and at the posteriorlateral side of the seminal vesicle. The pelvic plexus and the prostatic vessels formed neurovascular bundle (NVB) at the basilar part of the prostate. It was also at the posteriorlateral side of the membranous urethra. Conclusion The seminal vesicle and NVB can be used as the markers to avoid pelvic plexus injuries in urinary surgery, which is of remarkable clinical significance in the prevention of iatrogenic impotence.
