男性盆丛解剖标志在下尿路手术中的意义

为探寻下尿路手术中避免损伤盆丛的解剖标志，对１０个盆腔器官标本作盆丛大体解剖或大切片，观察盆丛与盆腔器官的毗邻关系，结果表明，盆丛位于直肠的前外侧，精囊腺的后外侧，在前列腺基底部与前列腺外侧的血管形成神经血管束，于尿道感染部的外侧和后外仙穿过尿生殖膈，认为精囊腺和神经血管束可作为下尿路术中避免损伤盆丛的解剖标志，文中还对盆丛的解剖分布及其与医源性阳萎的关系进行了讨论。

Roles of anatomical landmark in male pelvic plexus on lower urinary tract surgery

In an effort to delineat the exact relation of pelvic plexus to its adjacent organs, detailed anatomy on pelvic plexus or observation on whole mount sections of pelvic organs were carried out on 10 male cadavers. The study demonstrated that the pelvic plexus was located on the anterolateral to the rectum, posterolateral to the seminal vesicle, gradually forming neurovascular bundles (NVB) at the level of prostate and finally penetrating genitourinary diaphragm on lateral and posterolateral to the membranous urethra. Therefore the seminal vesicle and NVB can be used as landmarks intraoperatively to avoid injury to the pelvic plexus. Relation between anatomical distribution of pelvic plexus and impotence were also discussed.
