IMPORTANCE: Approximately 60% of women develop a uterine niche after a cesarean delivery (CD). A niche is associated with various gynecological symptoms including abnormal uterine bleeding, pain, and infertility, but there is little consens…

Endometrial disorders represent a major gynaecological burden. Current research models fail to recapitulate the nature and heterogeneity of these diseases, thereby hampering scientific and clinical progress. Here we developed long-term expa…

OBJECTIVE: To compare ultrasonographic features of uterine lesions with the findings at macroscopy and microscopy. METHODS: Case series of ten consecutive women undergoing a hysterectomy for uterine pathology. A preoperative transvaginal u…

STUDY QUESTION: Do sonographic characteristics of ovarian endometriomas vary with age in premenopausal women? SUMMARY ANSWER: With increasing age, multilocular cysts and cysts with papillations and other solid components become more common …

The use of in vitro three-dimensional ultrasound examination with needle stereotaxis after hysterectomy is illustrated in a case of extensive adenomyosis. The quality of the images at in vitro ultrasonography was compared with the quality o…

We will describe a case of a patient diagnosed with a rare identity of a benign lesion, "reactive nodular fibrous pseudotumor" (RNFP). It is a tumor which preoperatively can present as a malignant tumor and is only reported in 19 cases. Acc…

Characterizing ovarian masses enables patients with malignancy to be appropriately triaged for treatment by subspecialist gynecological oncologists, which has been shown to optimize care and improve survival. Furthermore, correctly classify…

Due to the confounding or unknown presence of endometriosis in both cases and controls, it is difficult to test the hypothesis that adenomyosis causes infertility. Based on the limited available evidence, there is evidence to support a caus…

BACKGROUND: To translate the concept of full-conditioning (FC) from animal experiments to the human, and to evaluate the efficacy for adhesion prevention. FC consisted of decreasing acute inflammation by 86% CO2+ 10% N2O + 4% O2 for the pne…

AIM: To evaluate the performance of subjective evaluation of ultrasound findings (pattern recognition) to discriminate endometriomas from other types of adnexal masses and to compare the demographic and ultrasound characteristics of the tru…

This review discusses uterine adenomyosis as a (co-)factor in female subfertility. The clinical presentation of adenomyosis uteri is reviewed as well as recent developments in non-invasive imaging modalities for the condition. Different tre…
