[Hematometra after hysteroscopic endometrium ablation--a case report].

13 months after a hysteroscopic endometrial ablation a haematometra was diagnosed in a 44 year-old women as a source of recurrent pelvic pain. The cause of the haematometra was a complete obliteration of the ostium cervicae internum.
