Office hysteroscopy in postmenopausal women on HRT with uterine bleeding Branka Žegura Gynecologic Clinic, University Clinical Centre Maribor, Slovenia Brijuni; 11.9.2011 QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. AUB and HRT Abnormal uterine bleeding (AUB) with HRT is unscheduled bleeding. It affects around 40 to 60% on combined HRT. Commonly leads to discontinuation of the therapy. Hickey M. Maturitas 2009. AUB and HRT AUB occurs with cyclical and continuous combined regimens. 38% on sequential and 41% on combined HRT in one year. 12% and 20%, respectively require endometrial biopsy. Ettinger B. Fertil Steril 1998 AUB and HRT Unscheduled bleeding is most common in the initial months and tends to settle with long-term use. Mechanisms of endometrial bleeding and combined HRT •wide range of combined HRT •varying prescribing schedules •no correlation between endometrial histology with the type or dose of HRT •individual variations in response to the same HRT AUB and HRT •poor compliance •systemic or pelvic pathology •40% of women with endometrial polyps and sub mucus fibroids •in the majority - no pathological cause for the bleeding HRT and endometrial hyperplasia Sequential HRT - 2.7 - 5% in over 3 years.

Normal uterine cavity (50.4%) 2. Abnormal uterine cavity: • endometrial polyps (36.8%), • myomas (10.2%) 3.

The gold standard for investigation of AUB is HSC with endometrial biopsy, if AUB continues after 6 months of HRT or if it recurs after amenorrhea Hvala! Thank you!
