BACKGROUND Accurate diagnosis of uterine abnormalities has become a core part of the fertility work-up. A variety of modalities can be used for the diagnosis of uterine abnormalities. OBJECTIVES This study was designed to assess the diagnostic accuracy of transvaginal ultrasonography (TVS) in uterine pathologies of infertile patients using hysteroscopy as(More)
Structural pathologies in the uterine cavity such as müllerian duct anomalies (MDAs) and intrauterine lesions (fibroids, polyps, synechiae) may have important roles in subinfertility, implantation failure and pregnancy outcome. Various imaging modalities such as hysterosalpingography (HSG), sonography, laparoscopy and hysteroscopy are used in the evaluation(More)
Background: To evaluate the diagnostic accuracy of transvaginal sonography (TVS) in infertile patients and compare its results with hysteroscopy, as the gold standard. Materials and Methods: A total of 679 infertile women who underwent both TVS and diagnostic hysteroscopy were retrospectively investigated. TVS was performed in the mid-follicular phase (days(More)
BACKGROUND Assessment of uterine abnormalities is a core part in infertility evaluation. OBJECTIVE The aim of this study was to evaluate the sensitivity and specificity of three-dimensional hysterosonography (3-DHS) in the diagnosis of uterine abnormalities in infertile women. MATERIALS AND METHODS The infertile women who visited Royan Institute and(More)
BACKGROUND Traditionally, septate uterus was diagnosed with invasive method like hysterosalpingography and hysteroscopy. Nowadays transvaginal ultrasonography was reported to be a sensitive tool for detection of septate uterus too. OBJECTIVE The objective of the present study was to evaluate the application of two dimensional ultrasound (2-DUS) and real(More)
Placental site trophoblastic tumor (PSTT) is a very rare variant of gestational trophoblastic tumor. It can occur after normal termination of pregnancy or spontaneous abortion and ectopic or molar pregnancy. There is a wide range of clinical manifestations from a benign condition to an aggressive disease with fatal outcome. One of the most important(More)
Trisomy 18 (Edwards syndrome) is the second most common trisomy among live born fetuses, with poor prognosis. Estimate of its incidence is between 1 in 4000- 16000 live births. Most of the chromosomal abnormalities in fetuses are detected by prenatal ultrasound findings in the first and second trimesters. In this case re- port, we present a partial type of(More)

BACKGROUND Osteoarthritis (OA) is a debilitating disease that typically affects a large number of the middle-aged and elderly population. Current treatment strategies have had limited success in these patients. This study aims to investigate the safety of treatment with autologous bone marrow (BM)-derived mesenchymal stem cells (MSCs) transplanted in(More)
