子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)后(hou)(hou)位(wei)，就是子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)的(de)(de)縱軸不(bu)變，整個子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)向(xiang)后(hou)(hou)方傾倒(dao)，容易使子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)頸(jing)呈上(shang)翹狀態，即(ji)子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)后(hou)(hou)傾，致使子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)頸(jing)不(bu)易浸(jin)泡在精液池中而可能影響受(shou)孕。子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)后(hou)(hou)位(wei)臨(lin)床上(shang)比(bi)較(jiao)(jiao)(jiao)常見，子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)后(hou)(hou)倒(dao)與子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)頸(jing)交界處形(xing)成(cheng)一個銳角者(zhe)，則稱為“子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)后(hou)(hou)傾后(hou)(hou)曲”，臨(lin)床上(shang)較(jiao)(jiao)(jiao)少見。子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)后(hou)(hou)位(wei)的(de)(de)形(xing)成(cheng)有先天(tian)性(xing)與后(hou)(hou)天(tian)性(xing)的(de)(de)區別，但大多數的(de)(de)子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)后(hou)(hou)位(wei)都可通(tong)過(guo)一定的(de)(de)生育(yu)指導(dao)順(shun)利懷(huai)孕，只(zhi)有少數較(jiao)(jiao)(jiao)嚴重的(de)(de)患者(zhe)需(xu)要(yao)接受(shou)外(wai)科治療子(zi)(zi)(zi)(zi)宮(gong)(gong)(gong)(gong)后(hou)(hou)位(wei)。

根據(ju)子(zi)宮(gong)后(hou)倒(dao)(dao)的(de)程度(du)(du)(du)不(bu)(bu)同，子(zi)宮(gong)后(hou)位(wei)分為Ⅰ、Ⅱ、Ⅲ度(du)(du)(du)。 輕(qing)度(du)(du)(du)子(zi)宮(gong)后(hou)位(wei)(Ⅰ-Ⅱ度(du)(du)(du))一般不(bu)(bu)出(chu)現癥(zheng)狀(zhuang)，無(wu)需治療，重度(du)(du)(du)子(zi)宮(gong)后(hou)位(wei)常出(chu)現癥(zheng)狀(zhuang)，主要表現為腰(yao)酸(suan)(suan)(suan)。輕(qing)者(zhe)僅為腰(yao)部(bu)酸(suan)(suan)(suan)脹不(bu)(bu)適，重者(zhe)整個腰(yao)部(bu)、骶尾(wei)部(bu)及兩側髂部(bu)均(jun)感酸(suan)(suan)(suan)脹難忍，個別患者(zhe)酸(suan)(suan)(suan)脹延伸(shen)到下(xia)背部(bu)和(he)兩側腹股溝。小腹部(bu)酸(suan)(suan)(suan)脹和(he)肛門墜脹感往往同時(shi)并存(cun)，勞累(lei)和(he)月經期癥(zheng)狀(zhuang)往往加(jia)重。若得不(bu)(bu)到及時(shi)矯正，還可(ke)繼發(fa)痛經、月經不(bu)(bu)調、白帶增多、性感不(bu)(bu)快、流產、不(bu)(bu)孕(yun)等。子(zi)宮(gong)后(hou)位(wei)的(de)患者(zhe)在受(shou)孕(yun)三(san)個月后(hou)，若后(hou)倒(dao)(dao)子(zi)宮(gong)仍未自動糾(jiu)正，則膀胱(guang)頸(jing)部(bu)及尿道的(de)變位(wei)和(he)宮(gong)頸(jing)上翹，可(ke)壓迫后(hou)尿道發(fa)生急性尿潴留。
