Abstract：
OBJECTIVE: Previous anatomical studies of the urogenital fascia (UGF) have focused on males, and there is a lack of relevant anatomical studies on the distribution of the extraperitoneal UGF in females.
METHODS: In this investigation, guided by the embryonic development of the female urogenital system, the ventral pelvic fascia structure of 10 female cadavers was dissected, and the distribution and morphology of female extraperitoneal UGF were observed, recorded in text, photographs and video, and 3D modeling was performed.
RESULTS: We find that in the female extraperitoneal space there is a migratory fascial structure, the UGF, which surrounds the urogenital system and extends from the perinephric region to the pelvis along with the development of the urogenital organs. The two layers of the UGF are composed of loose connective tissue rich in fat that surrounds the urogenital organs, their accessory vascular structures, and the nerves of the abdominopelvic cavity. In the pelvis, it participates in the formation of the ligamentous structures around the rectum and uterus. Finally, it surrounds the bladder and gradually moves into the loose connective tissue of the medial umbilical fold.
CONCLUSIONS: Sorting out the distribution characteristics of UGF has some reference value for studying the metastasis of gynecological tumors, the biomechanical structure of the female pelvis, and the surgical methods of gynecology, colorectal surgery, and hernia surgery.

摘要：
目的：先前对泌尿生殖道筋膜（UGF）的解剖学研究集中在男性，缺乏对女性腹膜外UGF分布的相关解剖学研究。
方法：在这项调查中，以女性泌尿生殖系统的胚胎发育为指导，解剖了10具女性尸体的腹侧骨盆筋膜结构，观察女性腹膜外UGF的分布和形态,记录在文本中，照片和视频,并进行了3D建模。
结果：我们发现，在女性腹膜外间隙有一个迁移筋膜结构，UGF,它围绕泌尿生殖系统，并随着泌尿生殖器官的发育从肾周区域延伸到骨盆。UGF的两层由富含脂肪的松散结缔组织组成，围绕着泌尿生殖器官，它们的附属血管结构,和腹肾盂腔的神经。在骨盆，它参与直肠和子宫周围韧带结构的形成。最后,它围绕膀胱，并逐渐进入脐带内侧褶皱的疏松结缔组织。
结论：整理UGF的分布特征对研究妇科肿瘤的转移有一定的参考价值。女性骨盆的生物力学结构，以及妇科的手术方法，结直肠手术,还有疝气手术.
