Results: Thirty-eight women were diagnosed of Cesaeran scar defectat TUS. The number of previous Caesarean sections in patients withuterine dehiscence and ectopic pregnancy in Cesarean scar is shownin Table 1. Eleven patients (29%) showed a uterine dehiscence.Seven cases were repaired by laparoscopy and 4 cases requiredhysterectomy. Five ectopic pregnancies (13%) were diagnosed atTUS. Two patients required hysterectomy, 2 were treated with localmethotrexate guided by TUS and 1 was surgically sutured. Twopatients (5%) had a complete uterine rupture. One of them diagnosed6 months after Cesarean section and required hysterectomy. Theother which was diagnosed during puerperium period was treatedby surgical repair.Conclusions: TUS is useful for detecting Cesarean scar defectsproviding information for a treatment in case of complications.

Objectives: To evaluate the Cesarean scar defect depth and theresidual myometrial thickness with 3-dimensional (3D) sonographyconcerning interobserver variation.Methods: Ten women were randomly selected from a largercohort of Cesarean scar ultrasound evaluations. All women wereexamined 6–16 months after their first Cesarean section with2D transvaginal sonography and had 3D volumes recorded. Twoobservers independently evaluated ‘‘off-line’’ each of the 3D volumesstored. Residual myometrial thickness (RMT) and Cesarean scardefect depth (D) was measured in the sagittal plane with an intervalof 1 mm across the entire width of the endometrium. RMT wasdefined as the shortest distance from the scar defect to the uterineserosa among all RMT measures, and D was defined similarly as thelargest depth of the scar defect extending from the uterine cavity.The median value for RMT and D for each observer as well as themedian difference in RMT and D between the two observers wascalculated.Results: The median value of RMT was 6.0 mm in observer 1(range 2.0–7.8) and 5.7 mm in observer 2 (range 2.1–7.6). Mediandifference in RMT between the two observers was 1.3 mm (range0.1–3.3). The median value of D was 2.6 mm in observer 1 (range1.2–5.4) and 2.4 mm in observer 2 (range 1–4.9), and the mediandifference was 1.0 mm (range 0.3–2.8) between observer 1 and 2.Conclusions: The 3D interobserver variation concerning measures ofRMT and D seems good. The role of 3D sonography in evaluationsof Cesarean section scar size and residual myometrium needs furtherinvestigation.

Objectives: Autoimmune oophoritis remains an almost undiagnosedpathology in wide clinical practice up to date. Autoimmuneoophoritis is characterized by certain histologic changes such ascharacteristic inflammatory infiltration in the inner theca-layer of
growing follicles. It is obvious that such morphological changes ofovarian tissue should be visible by ultrasound.Methods: In detailed ultrasound examination of ovaries in 34 womenwith high levels of anti-ovarian antibodies (61.1–131.4 IU/ml) asignificant increase of echogenicity of ovarian stroma was detected.All patients then underwent diagnostic laparoscopy with histologicexamination of ovarian biopsy specimens.Results: Revealed were different degrees of changes characteristicfor autoimmune ovarian pathology. The AMH level in serumof examined women was significantly lower (0.28–0.89 ng/mL)than normal (1.0–3.5 ng/mL), and it correlated with the degreeof lymphoid infiltration and fibrous changes in ovarian structures.In Doppler examination sometimes avascularization of stroma wasseen. In examination of intraovarian artery blood flow, monotonouscurves were revealed with maximal flow velocity of 5.1–11.3 cm/secwhich corresponds to the mean flow velocity of early proliferationstage of non-ovulating ovary. The numeric values of RI (0.65–0.93)also did not significantly change during the menstrual cycle and weregreater than those of healthy females in ovulatory cycle.Conclusions: Women with autoimmune oophoritis had changes inultrasound structure of the ovaries such as increased echogenicity ofthe stroma, intraovarian blood flow, low levels of AMH dependingon the degree of histological manifestations of autoimmune injury,which allows to recommend detailed workup directed at detectionof antiovarian antibodies in women with olygo/opso- or amenorrheawith above listed ultrasound findings and low levels of AMH.

Objectives: This study aims at evaluating the pelvic floor biometriesafter the delivery in Chinese primiparous women. The relationshipwith mode of delivery (MOD) was explored.Methods: Nulliparous Chinese women with singleton pregnancywere assessed at 10–13 weeks of gestation, and at 8 weeks,6 months and 12 months after delivery. Trans-labial 3D-ultrasoundwas performed at rest, at Valsalva maneuver and at pelvic floorcontraction during each visit. MOD was determined by obstetricindications. Offline analysis of USG volume data set were doneby an investigator blinded to the information. Position of thebladder neck, middle compartment (most inferior part of cervix)and posterior compartment (ano-rectal junction) and the hiatal areawere measured.Results: In all, 131 women completed the study. Their mean age was30.7 ± 3.6 years, mean gestation at delivery was 275 ± 12.6 daysand mean birth weight was 3.0 ± 0.4 kg. 106 (81%) had vaginaldelivery (62% normal delivery and 19% instrumental delivery) and25 (19%) had caesarean section (CS) (5 elective and 20 emergency).There was no difference of gestation at delivery and neonatalbirth weight between the groups of MOD. When compared tothe first trimester biometries, there was significant descent of middlecompartment and increase in hiatal area at rest, VM and PFMC till12 months after delivery in vaginal delivery group. There was alsosignificant bladder neck descent at rest and at VM at 12 months. InCS group, there was also significant descent of middle compartmentat rest, at VM and PFMC till 12 months after delivery; however,there was only increase in hiatal area during VM.Conclusions: At one year after delivery, there was significant descentof middle compartment of women at rest, at VM and PFMC for bothvaginal delivery and CS. However, there was significant increase inhiatal area at VM only in CS, while there was increase in hiatal areaalso at rest and at PFMC in women with vaginal delivery.
