现代解剖学对盆底结构的描述以腔室理论为代表。该理论在垂直方向上将盆底分为前、中、后3个腔室,前腔室包括阴道前壁、膀胱、尿道;中腔室包括阴道顶部、子宫;后腔室包括阴道后壁、直肠。由此将盆腔脏器脱垂量化到各个腔室。在水平方向上,将阴道支持轴分为3个水平,即第1水平:顶 Modern anatomy of the pelvic floor structure is represented by the chamber theory. The theory vertically divides the pelvic floor into three chambers: front, middle and back. The anterior chamber includes the anterior vaginal wall, bladder and urethra. The middle chamber includes the vaginal top and the uterus. The posterior chamber includes the vaginal posterior wall, rectum. Pelvic organ prolapse is thereby quantified to each chamber. In the horizontal direction, the vaginal support shaft is divided into three levels, the first level: the top
