Background and Objectives: Measurement of cervical length using Transvaginal Sonography (TVS) is commonly used to identify those patients of threatened preterm labor who are likely to deliver. Biochemical markers in cervical secretions namely fetal fibronectin and Phosphorylated Insulin like Growth Factor Binding Protien-1 (phIGFBP-1) have also been used to improve predictability. This study ev...

Background: Preterm labor is the presence of uterine contractions sufficient frequency and intensity to affect progressive effacement dilation cervix prior term gestation. Shortening funneling was first described be associated with diagnosis cervical incompetence, Transvaginal sonographic measurement length could used predict a risk for preterm delivery significant proportion births. Cervical m...

AIMS A very good knowledge of human embryology is mandatory not only for the correct sonographic assessment of the developing brain, but also for better understanding the origins of congenital anomalies involving the central nervous system. 3D transvaginal sonography may be an effective technique for imaging the developing brain. The aims of this explorative study are to demonstrate the feasibi...

background: abnormal uterine bleeding (aub) is one of the most common clinical problems in gynecology. transvaginal sonography (tvs) and hysteroscopy are two diagnostic methods for patients with aub. for most of the patients with aub, diagnostic hysteroscopy can be done in clinic with minimal discomfort and much lower expense than operative room. materials and methods: in our clinical trial stu...

OBJECTIVE To examine the natural history of cervical length shortening in women who had experienced at least one prior spontaneous preterm birth at between 17+0 and 33+6 weeks' gestation. METHODS This was an analysis of prerandomization data from the multicenter Vaginal Ultrasound Cerclage Trial. Serial cervical length was measured by transvaginal sonography in 1014 high-risk women at 16+0 to...
