绝经后子宫出血的病因分析

Etiology of postmenopausal bleeding

目的:探讨绝经后子宫出血(PMB)的病因分类和特点。方法:回顾性分析本院近3年来176例PMB患者的资料,根据病理检查的结果确定病因,分析其特点。结果:176例PMB患者中非器质性病变46例(26.1%);良性病变79例(44.9%);恶性病变51例(29.0%)。50～70岁组以良性病变居多,而70～80岁组则以恶性病变居多(χ2=19.962,P=0.001)。同时,非器质性病变平均年龄最低,而恶性病变的平均年龄最高(F=8.774,P=0.003)。恶性PMB的危险因素主要有患者的年龄、绝经年限、出血距初诊时间及子宫深度4种。结论:绝经后子宫出血病因以良性病变为主,但随着年龄的增加,恶性疾病发生的机会增高,应引起注意。

Objective：To investigate the etiology for postmenopausal bleeding（PMB）.Methods：A retrospective analyzed of 176 patients with PMB 3 years in our hospital was used in this study.According to the results of pathological examination,we analyzed its etiology.Results：In 176 patients with PMB,46 patients（26.1%） had no organic disease;79 patients（44.9%） had benign lesions;51 patients（29.0%） had malignant lesions.50-70 age group were mostly benign lesions,while the 70-80 age group,mostly malignant disease（χ2=19.962,P=0.001）.Meanwhile,the average age of patients with non-organic disease were lower,and the average age of patients with malignant lesions were higher（F=8.774,P=0.003）.Risk factors for malignant PMB were patient＇s age,years since menopause,uterine bleeding time and the depth of uterine.Conclusion：The cause of postmenopausal bleeding is benign lesions.However,with increasing age,the chance of malignant disease increased,which should pay more attention.
