子(zi)(zi)宮(gong)(gong)(gong)后(hou)(hou)(hou)位(wei)(wei)，就是子(zi)(zi)宮(gong)(gong)(gong)的(de)縱軸不變，整個(ge)子(zi)(zi)宮(gong)(gong)(gong)向后(hou)(hou)(hou)方(fang)傾倒(dao)，容易使(shi)子(zi)(zi)宮(gong)(gong)(gong)頸(jing)呈(cheng)上(shang)(shang)翹狀態，即(ji)子(zi)(zi)宮(gong)(gong)(gong)后(hou)(hou)(hou)傾，致使(shi)子(zi)(zi)宮(gong)(gong)(gong)頸(jing)不易浸泡(pao)在精液池中而可(ke)能影響受(shou)孕。子(zi)(zi)宮(gong)(gong)(gong)后(hou)(hou)(hou)位(wei)(wei)臨床上(shang)(shang)比(bi)較(jiao)常(chang)見(jian)，子(zi)(zi)宮(gong)(gong)(gong)后(hou)(hou)(hou)倒(dao)與子(zi)(zi)宮(gong)(gong)(gong)頸(jing)交界處形(xing)(xing)成一個(ge)銳角者，則稱(cheng)為“子(zi)(zi)宮(gong)(gong)(gong)后(hou)(hou)(hou)傾后(hou)(hou)(hou)曲”，臨床上(shang)(shang)較(jiao)少見(jian)。子(zi)(zi)宮(gong)(gong)(gong)后(hou)(hou)(hou)位(wei)(wei)的(de)形(xing)(xing)成有先天性與后(hou)(hou)(hou)天性的(de)區別，但大(da)多(duo)數(shu)的(de)子(zi)(zi)宮(gong)(gong)(gong)后(hou)(hou)(hou)位(wei)(wei)都可(ke)通過一定的(de)生育指(zhi)導順利懷孕，只有少數(shu)較(jiao)嚴重的(de)患者需要接受(shou)外科治療(liao)子(zi)(zi)宮(gong)(gong)(gong)后(hou)(hou)(hou)位(wei)(wei)。

根據子(zi)宮(gong)后(hou)倒(dao)的(de)程度(du)不(bu)同，子(zi)宮(gong)后(hou)位(wei)(wei)(wei)分為Ⅰ、Ⅱ、Ⅲ度(du)。 輕度(du)子(zi)宮(gong)后(hou)位(wei)(wei)(wei)(Ⅰ-Ⅱ度(du))一般不(bu)出現(xian)癥狀，無需治療(liao)，重度(du)子(zi)宮(gong)后(hou)位(wei)(wei)(wei)常(chang)出現(xian)癥狀，主要表現(xian)為腰(yao)酸(suan)。輕者(zhe)僅為腰(yao)部酸(suan)脹不(bu)適，重者(zhe)整個腰(yao)部、骶(di)尾部及(ji)兩側髂部均感酸(suan)脹難忍(ren)，個別患(huan)者(zhe)酸(suan)脹延伸到(dao)下背(bei)部和兩側腹股溝(gou)。小腹部酸(suan)脹和肛(gang)門墜脹感往(wang)往(wang)同時并存，勞累和月(yue)經(jing)期(qi)癥狀往(wang)往(wang)加重。若得不(bu)到(dao)及(ji)時矯正(zheng)，還可繼發痛經(jing)、月(yue)經(jing)不(bu)調、白帶(dai)增多、性感不(bu)快、流產、不(bu)孕(yun)等。子(zi)宮(gong)后(hou)位(wei)(wei)(wei)的(de)患(huan)者(zhe)在受(shou)孕(yun)三(san)個月(yue)后(hou)，若后(hou)倒(dao)子(zi)宮(gong)仍未(wei)自動糾(jiu)正(zheng)，則膀胱頸部及(ji)尿道的(de)變位(wei)(wei)(wei)和宮(gong)頸上翹，可壓(ya)迫后(hou)尿道發生急(ji)性尿潴留。
