子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)后(hou)(hou)位(wei)，就(jiu)是子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)的(de)縱軸不變，整個(ge)子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)向后(hou)(hou)方傾(qing)倒，容易使(shi)子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)頸呈上(shang)翹狀(zhuang)態，即子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)后(hou)(hou)傾(qing)，致使(shi)子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)頸不易浸(jin)泡在精液池中而(er)可(ke)能影響受孕。子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)后(hou)(hou)位(wei)臨床上(shang)比較常見，子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)后(hou)(hou)倒與子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)頸交界處形成一個(ge)銳角者(zhe)，則(ze)稱為“子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)后(hou)(hou)傾(qing)后(hou)(hou)曲”，臨床上(shang)較少見。子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)后(hou)(hou)位(wei)的(de)形成有先(xian)天(tian)性(xing)與后(hou)(hou)天(tian)性(xing)的(de)區(qu)別(bie)，但大多數的(de)子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)后(hou)(hou)位(wei)都可(ke)通(tong)過(guo)一定的(de)生育指導順利(li)懷孕，只有少數較嚴重的(de)患者(zhe)需要(yao)接受外科治療子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)(gong)后(hou)(hou)位(wei)。

根據子(zi)宮(gong)后倒的程度(du)不(bu)(bu)同(tong)，子(zi)宮(gong)后位(wei)分為(wei)Ⅰ、Ⅱ、Ⅲ度(du)。 輕(qing)度(du)子(zi)宮(gong)后位(wei)(Ⅰ-Ⅱ度(du))一般不(bu)(bu)出(chu)現癥(zheng)狀(zhuang)，無需治(zhi)療，重(zhong)度(du)子(zi)宮(gong)后位(wei)常出(chu)現癥(zheng)狀(zhuang)，主(zhu)要表現為(wei)腰酸。輕(qing)者僅為(wei)腰部(bu)酸脹(zhang)(zhang)不(bu)(bu)適，重(zhong)者整(zheng)個腰部(bu)、骶尾部(bu)及(ji)兩(liang)側髂部(bu)均感酸脹(zhang)(zhang)難忍，個別患(huan)者酸脹(zhang)(zhang)延伸到下(xia)背(bei)部(bu)和兩(liang)側腹股溝。小腹部(bu)酸脹(zhang)(zhang)和肛門墜脹(zhang)(zhang)感往(wang)(wang)往(wang)(wang)同(tong)時并存，勞累和月(yue)經期癥(zheng)狀(zhuang)往(wang)(wang)往(wang)(wang)加(jia)重(zhong)。若(ruo)得不(bu)(bu)到及(ji)時矯正(zheng)，還可繼發(fa)痛經、月(yue)經不(bu)(bu)調(diao)、白(bai)帶增多、性感不(bu)(bu)快、流產、不(bu)(bu)孕(yun)等。子(zi)宮(gong)后位(wei)的患(huan)者在受孕(yun)三個月(yue)后，若(ruo)后倒子(zi)宮(gong)仍未(wei)自動糾(jiu)正(zheng)，則膀胱(guang)頸(jing)部(bu)及(ji)尿(niao)道(dao)的變位(wei)和宮(gong)頸(jing)上(shang)翹，可壓迫后尿(niao)道(dao)發(fa)生(sheng)急(ji)性尿(niao)潴留。
