膀胱三角区一般认为是不适宜作膀胱部份切除术的,因为膀胱三角区深而固定,该区膀胱壁无法游离。我们复习了该区解剖,膀胱三角之壁分三层,内层粘膜,中层肌层,外层是菲薄之纤维膜,这三层相互紧贴固定。膀胱三角之后面,男的与直肠前壁相邻,女的与阴道前壁相邻,在膀胱三角与直肠(女为阴道)之间有一很小间隙,称膀胱直肠间隙(女性称膀胱阴道间隙),该间隙中央有一致密结缔组织构成的膀胱直肠筋膜(女
Bladder trigone is generally considered inappropriate for partial resection of the bladder, because the bladder triangle deep and fixed, the bladder wall can not be free. We reviewed the anatomy of the area, the wall of the bladder triangle divided into three layers, the inner mucosa, the middle muscularis, the outer is the meager fibrous membrane, the three layers close to each other fixed. Behind the trigone of the bladder, the male is adjacent to the anterior wall of the rectum, and the female is adjacent to the anterior wall of the vagina. There is a small gap between the bladder trigone and the rectum (female vagina), which is called the bladder rectum space ), The gap has a dense central connective tissue bladder tissue (female
