目的 :为了减少某些妇科手术的并发症 ,提高治愈率。方法 :2 0例成人女性标本用于观察盆腔脏器旁结构的内容、分层 ;盆丛的组成和分区定位 ;子宫韧带与盆丛的关系。结果 :盆腔脏器旁结构大致可以分为 3层 ,盆丛分为 3部 ,骶子宫韧带中含盆内脏神经。结论 :搞清楚盆腔脏器旁结构的复杂关系对于指导某些盆腔手术至关重要。 Objective: In order to reduce the complications of some gynecological surgery and improve the cure rate. Methods: Twenty adult female specimens were used to observe the content and stratification of paravertebral organs. The composition and location of pelvic plexus were also studied. The relationship between uterine ligaments and pelvic plexus was analyzed. Results: The pelvic organ structure can be roughly divided into three layers, the pelvic plexus is divided into three parts, the sacral uterine ligament contains pelvic visceral nerve. CONCLUSIONS: Finding the complex relationship of the paravertebral structures in the pelvis is crucial for guiding some pelvic surgeries.
