labor is a physiological event involving a sequential, integrated set of changes within the myometrium, deciduas, and uterine cervix that occur gradually over a period of days to weeks. biochemical connective tissue changes in the uterine cervix appear to precede uterine contractions and cervical dilation, and all of these events usually occur before rupture of the fetal membranes. in other wor...

BACKGROUND Maternal mortality and morbidity are the priority agenda for sub-Saharan Africa including Ethiopia. Uterine rupture is the leading cause of maternal and fetal death in developing countries. Limited evidence is available on the magnitude of uterine rupture; maternal and fetal outcomes of uterine rupture and factors associated with maternal death secondary to uterine rupture in Ethiopi...

background: the purpose of the study was to evaluate the role of uterine blood flow parameters measured by uterine artery two-dimensional (2d)-power color doppler (pcd) ultrasound in predicting fertility outcomes in women undergoing ivf-et cycles. methods: in this prospective observational study, a total of 188 infertile women who underwent ivf-et cycles were investigated. uterine artery 2d-pd ...

BACKGROUND Abnormal uterine bleeding is a common gynecologic problem. Fractional curettage, evacuation and curettage, and dilatation curettage are common gynecologic procedures for investigation and treatment of abnormal uterine bleeding. To perform all these procedures, anesthesia is needed but technique varies among hospitals. The standard procedure of uterine curettage was performed after pa...

Uterine rupture rarely occurs during pregnancy, but it is a critical situation if so. It is already known that a history of uterine surgeries, such as cesarean section or myomectomy, is a risk factor for uterine rupture. Currently, the laparoscopic adenomyomectomy is a widely performed procedure, but associated risks have not been defined. We observed a case of spontaneous uterine rupture in a ...

Cox, Blair E., Timothy A. Roy, and Charles R. Rosenfeld. Angiotensin II mediates uterine vasoconstriction through -stimulation. Am J Physiol Heart Circ Physiol 287: H126–H134, 2004. First published February 19, 2004; 10.1152/ajpheart.00046.2003.—Intravenous angiotensin II (ANG II) increases uterine vascular resistance (UVR), whereas uterine intra-arterial infusions do not. Type 2 ANG II (AT2) r...

Cutaneous leiomyomas, rare benign tumors originating from the arrector pili muscle of the hair follicle, can be associated with the common uterine fibroids in a syndrome called multiple cutaneous and uterine leiomyomas. Multiple cutaneous and uterine leiomyomas are inherited as an autosomal dominant trait, providing an excellent opportunity for the study of the common non-Mendelian manifestatio...

Uterine carcinoma of the lower uterine segment (LUS) is a rare tumor that accounts for 3-3.5% of cases of uterine malignant cancer. The tumor arises from the lower region of the uterine body through the upper region of the cervix. The present study reported a case of clear cell carcinoma that originated from the LUS. A 50-year-old woman visited a local hospital due to irregular vaginal bleeding...

Nitric oxide synthase (NOS) contributes to estradiol-17beta (E(2)beta)-induced uterine vasodilation, but additional mechanisms are involved, and the cellular pathways remain unclear. We determined if 1) uterine artery myocytes express potassium channels, 2) E(2)beta activates these channels, and 3) channel blockade plus NOS inhibition alters E(2)beta-induced uterine vasodilation. Studies of cel...

Objective: The purpose of this study was to evaluate the efficacy, safety, and benefits of hysteroscopic surgery in the treatment of dysfunctional uterine bleeding (DUB) or intrauterine lesions causing uterine bleeding. Methods: This study prospectively enrolled 100 patients who underwent operative hysteroscopy in tertiary referral university center because of uterine bleeding due to endometria...
