子(zi)宮(gong)(gong)(gong)后(hou)(hou)位(wei)(wei)，就是子(zi)宮(gong)(gong)(gong)的(de)縱軸(zhou)不(bu)變，整個子(zi)宮(gong)(gong)(gong)向后(hou)(hou)方傾倒，容易(yi)使子(zi)宮(gong)(gong)(gong)頸呈上(shang)(shang)翹狀(zhuang)態，即子(zi)宮(gong)(gong)(gong)后(hou)(hou)傾，致使子(zi)宮(gong)(gong)(gong)頸不(bu)易(yi)浸(jin)泡在精(jing)液池(chi)中而可能影響受(shou)孕。子(zi)宮(gong)(gong)(gong)后(hou)(hou)位(wei)(wei)臨床(chuang)(chuang)上(shang)(shang)比較常(chang)見，子(zi)宮(gong)(gong)(gong)后(hou)(hou)倒與子(zi)宮(gong)(gong)(gong)頸交界(jie)處形(xing)(xing)成一(yi)個銳角者，則稱為“子(zi)宮(gong)(gong)(gong)后(hou)(hou)傾后(hou)(hou)曲”，臨床(chuang)(chuang)上(shang)(shang)較少(shao)見。子(zi)宮(gong)(gong)(gong)后(hou)(hou)位(wei)(wei)的(de)形(xing)(xing)成有先天(tian)性(xing)與后(hou)(hou)天(tian)性(xing)的(de)區別，但大多數(shu)的(de)子(zi)宮(gong)(gong)(gong)后(hou)(hou)位(wei)(wei)都(dou)可通(tong)過(guo)一(yi)定的(de)生育指導順利懷孕，只有少(shao)數(shu)較嚴重的(de)患者需要接受(shou)外科治療子(zi)宮(gong)(gong)(gong)后(hou)(hou)位(wei)(wei)。

根據子(zi)宮(gong)(gong)(gong)(gong)后(hou)倒的(de)(de)程度(du)不(bu)(bu)同，子(zi)宮(gong)(gong)(gong)(gong)后(hou)位分為(wei)Ⅰ、Ⅱ、Ⅲ度(du)。 輕度(du)子(zi)宮(gong)(gong)(gong)(gong)后(hou)位(Ⅰ-Ⅱ度(du))一般不(bu)(bu)出(chu)現(xian)癥狀(zhuang)，無需治療(liao)，重度(du)子(zi)宮(gong)(gong)(gong)(gong)后(hou)位常(chang)出(chu)現(xian)癥狀(zhuang)，主要表現(xian)為(wei)腰酸(suan)。輕者(zhe)(zhe)僅為(wei)腰部(bu)(bu)酸(suan)脹(zhang)(zhang)不(bu)(bu)適，重者(zhe)(zhe)整個腰部(bu)(bu)、骶尾部(bu)(bu)及兩側髂部(bu)(bu)均感酸(suan)脹(zhang)(zhang)難忍，個別(bie)患者(zhe)(zhe)酸(suan)脹(zhang)(zhang)延伸到(dao)下背部(bu)(bu)和兩側腹股溝。小腹部(bu)(bu)酸(suan)脹(zhang)(zhang)和肛門墜脹(zhang)(zhang)感往往同時(shi)并存(cun)，勞累和月(yue)經(jing)期癥狀(zhuang)往往加(jia)重。若得不(bu)(bu)到(dao)及時(shi)矯正，還(huan)可(ke)(ke)繼(ji)發痛經(jing)、月(yue)經(jing)不(bu)(bu)調、白帶增多、性感不(bu)(bu)快、流產、不(bu)(bu)孕等(deng)。子(zi)宮(gong)(gong)(gong)(gong)后(hou)位的(de)(de)患者(zhe)(zhe)在受孕三個月(yue)后(hou)，若后(hou)倒子(zi)宮(gong)(gong)(gong)(gong)仍未自(zi)動糾正，則膀胱頸(jing)部(bu)(bu)及尿道的(de)(de)變位和宮(gong)(gong)(gong)(gong)頸(jing)上翹，可(ke)(ke)壓迫后(hou)尿道發生(sheng)急性尿潴留。
