OBJECTIVES: (carbon dioxide) emission from the MRI scanner, MR-HIFU device, and the medication used, and analyzed solid waste produced during treatment. METHODS: emission based on the energy used by the MRI scanner and MR-HIFU device and th…

BACKGROUND: Abnormal uterine bleeding (AUB) has a significant socioeconomic impact since it considerably impacts quality of life. Therapeutic options are frequently based on trial and error and do not target disease aetiology. Pathophysiolo…

BackgroundHysteroscopic resection is the first-choice treatment for symptomatic type 0 and 1 fibroids. Traditionally, this was performed under general anesthesia. Over the last decade, surgical procedures are increasingly being performed in…

OBJECTIVES: To evaluate whether the Morphological Uterus Sonographic Assessment (MUSA) features of adenomyosis need to be better defined and, if deemed necessary, to reach consensus on the updated definitions. METHODS: A modified Delphi pr…

BackgroundMagnetic resonance image-guided high-intensity-focused ultrasound (MR-HIFU) is a rather new, noninvasive option for the treatment of uterine fibroids. It is safe, effective, and has a very short recovery time. However, a lack of p…

Uterine disorders are often presented with overlapping symptoms. The microvasculature holds specific information important for diagnosing uterine disorders. Conventional sonography is an established diagnostic technique in gynecology, but i…

Abnormal menstrual bleeding (AUB) is a collective name for all vaginal bleeding problems such as heavy menstrual bleeding, intermenstrual bleeding, spotting and postmenopausal bleeding. To address AUB the classification of the International…

BACKGROUND: Adenomyosis commonly occurs with abnormal uterine bleeding (AUB) and is associated with subfertility and a higher miscarriage rate. Recent evidence showed abnormal vascularization in the endometrium in patients with adenomyosis,…

ObjectiveTo generate guidance for detailed uterine niche evaluation by ultrasonography in the non-pregnant woman, using a modified Delphi procedure amongst European experts.MethodsTwenty gynecological experts were approached through their m…

The aims of this prospective diagnostic evaluation study were (i) to estimate the inter-observer agreement and reproducibility of real-time sonoelastography and real-time gray-scale ultrasound in the measurement of uterine and fibroid volum…

OBJECTIVES: To investigate the accuracy and reliability of 3-dimensional (3D) transvaginal sonography in classifying submucous fibroids using the International Federation of Gynecology and Obstetrics PALM-COEIN (polyp, adenomyosis, leiomyom…

ObjectiveTo evaluate the effectiveness of a laparoscopic niche resection on niche-related symptoms and/or fertility-related problems, ultrasound findings and quality of life.DesignProspective cohort study.SettingUniversity hospital.Populati…

BACKGROUND: Adenomyosis is a benign uterine disease characterized by invasion of endometrium into the myometrium resulting in heavy menstrual bleeding and pain (dysmenorrhea). Hysterectomy is established as the final treatment option when c…

PurposeSince the introduction of minimally invasive gynecologic surgery, the percentage of advanced laparoscopic procedures has greatly increased worldwide. It seems therefore, timely to standardize laparoscopic gynecologic care according t…

BACKGROUND: Focal abnormalities most commonly acquired within the uterine cavity include endometrial polyps (arising from the endometrium) and submucous fibroids (arising from the myometrium). These benign abnormalities can cause several pr…

PURPOSE: The purpose of this study was to assess clinical outcomes 7 years after uterine artery embolization (UAE) in the treatment of symptomatic adenomyosis. MATERIALS AND METHODS: In this prospective cohort study, one specialized hospita…

The effect of uterine artery embolization (UAE) on symptomatic adenomyosis was evaluated in a systematic review and meta-analysis. Four groups were evaluated: short-term ( 12 months) pure adenomyosis, and long-term combined adenomyosis. Imp…

Background: Adenomyosis is a benign uterine disease characterized by invasion of endometrium into the myometrium resulting in heavy menstrual bleeding and pain (dysmenorrhea). Hysterectomy is established as the final treatment option when c…

BACKGROUND Adenomyosis is a benign uterine disease characterized by invasion of endometrium into the myometrium resulting in heavy menstrual bleeding and pain (dysmenorrhea). Hysterectomy is established as the final treatment option when c…

Uterine leiomyoma is a highly prevalent benign gynecologic neoplasm that affects women of reproductive age. Surgical procedures commonly employed to treat symptomatic uterine fibroids include myomectomy or total or sub-total hysterectomy. T…

We evaluated the additional value of elastography in addition to conventional gray-scale ultrasound, for diagnosing uterine fibroids and adenomyosis. We performed a prospective cohort study with MRI as a reference test. Random stored cinelo…

Caesarean section (CS) results in the occurrence of the phenomenon 'niche'. A 'niche' describes the presence of a hypoechoic area within the myometrium of the lower uterine segment, reflecting a discontinuation of the myometrium at the site…

The aim of this study was to test the reproducibility of elastography in the diagnosis of uterine abnormalities. We performed a prospective case control study with MRI as a reference test. Twenty premenopausal woman with the diagnosis intra…

OBJECTIVES: Sonoelastography is an ultrasound-imaging technique that measures tissue strain. The aim of this study was to define, in a systematic manner, specific sonoelastographic characteristics of the myometrium, fibroids and adenomyosis…

Sono-elastography is an imaging technique added to sonography, measuring tissue strain. The aim of this study is to systematically define specific sono-elastographic characteristics of the myometrium, fibroids and adenomyosis and evaluate t…
