The role of ultrasound in the assessment of the female pelvis whether using transabdominal/ transluminal approach is well established. Little reported about the use of the superficial transperineal approach that could provides full assessment of the lower cervix and vagina which may be overlooked in the standard examinations. Proximity of the probe to the vagina helps not just the detection of organ abnormalities yet also proper characterization and differentiation of vaginal masses. Advances in Knowledge: The indications, technique of scanning and limitations of transperineal ultrasound in the evaluation of the lower uterine segment...

BACKGROUND: Rates of cesarean delivery are continuously increasing in industrialized countries, with repeated cesarean accounting for about a third of all cesareans. Women who have undergone a first cesarean are facing a difficult choice for their next pregnancy, i.e.: (1) to plan for a second cesarean delivery, associated with higher risk of maternal complications than vaginal delivery; or (b) to have a trial of labor (TOL) with the aim to achieve a vaginal birth after cesarean (VBAC) and to accept a significant, but rare, risk of uterine rupture and its related maternal and neonatal complications...

RATIONALE: Epithelioid trophoblastic tumor (ETT) is a distinctive but rare gestational trophoblastic neoplasia (GTN) composed of chorionic-type intermediate trophoblast cells. Approximately 50% ETT arose from the uterine cervix or lower uterine segment following a previous pregnancy with vaginal bleeding. With its unusual ability to simulate an invasive epithelioid neoplasm, ETT frequently poses a diagnostic challenge, especially involving the uterine cervix. PATIENT CONCERNS: We herein report the case of a 60-year-old female with persistent vaginal bleeding and middle-level elevation of serum human chorionic gonadotropin (hCG)...

OBJECTIVES: Assessment of deep (>50%) myometrial invasion by dual-energy CT (DECT) and Trans-Vaginal US (TVUS) in patients with endometrial cancer. METHODS: We retrospectively enrolled patients with endometrial cancer who underwent DECT and TVUS for pre-surgical staging. Three sets of images were evaluated: 70 keV (routine CT images), 50 keV, and iodine-water reconstructions. The gold standard was pathology after surgery. The agreement between the different imaging modalities and the gold standard was estimated...

OBJECTIVE: Obstetric anal sphincter injuries are one of the most significant complications of vaginal delivery that give way to fecal incontinence, which is defined as the involuntary leakage of gas, fluid or solid stool. Although sphincter injuries are seen in 0.5-9% of all deliveries. It has been reported that 20-41% of women who had vaginal deliveries had occult anal sphincter injuries as endoanal ultrasonography began to be used by physicians. The aim of our study was to investigate the relationship between fecal incontinence, whose incidence increases dramatically during the postmenopausal stage, and occult anal sphincter injuries...

Herlyn-Werner-Wunderlich syndrome is an unusual congenital anomaly of the female genitourinary system, which is described as uterine didelphys with Obstructed Hemi-vagina and Ipsilateral Renal Anomaly (OHIRA), also known as OHVIRA syndrome. Typical symptoms are pelvic pain, tenderness, pelvic mass due to blood collection in the obstructed hemi-vagina and uterus, and dysmenorrhea that usually begins shortly after menarche. Clinical suspicion is very important for diagnosis and correct management avoids both short- and long-term complications...

BACKGROUND: Bilateral tubal ectopic pregnancies are a rare subset of ectopic pregnancy that can pose a diagnostic dilemma for clinicians. There is no distinct clinical presentation for bilateral tubal ectopic pregnancies, although they are typically associated with assistive reproductive techniques. In addition, there is no single diagnostic feature to help clinicians delineate bilateral tubal ectopic pregnancies from other types of ectopic pregnancy prior to passing the discriminatory zone (such as heterotopic pregnancy or twin ectopic [two gestational sacs in one tube])...

Vaginal delivery may cause levator avulsion, which may increase the risk of pelvic floor dysfunction (PFD). To explore the morphological changes of the levator ani muscle (including the puborectalis and iliococcygeus) and levator avulsion after vaginal delivery, translabial tomographic ultrasound imaging (TUI) was used to examine 80 women 45-60 days after their vaginal delivery. Subsequently, magnetic resonance imaging (MRI) was performed if at least one-sided puborectalis avulsion was found on TUI. The incidence of puborectalis avulsion in these postpartum women was 13...

Transabdominal and transvaginal sonography are used to measure bladder wall and detrusor thickness. Only transvaginal sonography has been used to measure the vaginal wall thickness. We describe the use of transabdominal sonography to measure the total vaginal wall thickness and total vaginal mucosal thickness at the bladder trigone. The mean bladder wall thickness and SD from published data were within the 95% confidence interval of our data. Total vaginal and mucosal thicknesses are reliable measurements, which require specific evaluation in a postmenopausal population...

OBJECTIVE: Isthmocele represents a reservoir on the anterior wall of the uterine isthmus or of the cervical canal at the site of a previous cesarean delivery scar. Recently, it has been clarified that it might be the cause of several gynecologic symptoms, as most common abnormal uterine bleeding. Hysteroscopy and trans-vaginal ultrasound are considered the gold standard for the diagnosis of this defect. Resectoscopic treatment can be considered effective in small size defects, but no randomized clinical trials are available...

BACKGROUND: An intrauterine device placed immediately following a delivery can serve as an effective and safe contraceptive strategy in the postpartum period. There is limited evidence that the levonorgestrel intrauterine system may have a higher rate of expulsion compared to the copper intrauterine device; however, rates of expulsion for these 2 intrauterine device types have not been compared directly. OBJECTIVE: We sought to compare expulsion rates by 12 weeks' postpartum for the levonorgestrel intrauterine system and copper intrauterine device...
