Poster abstracts just above the junction up to the renal pelvis with a diameter of 8.4 mm. 2D USG showed the renal calyceal dilatation (Figure 1), but the ureteral dilatation was difficult to identify because of the liquid containing image of the fetal intestines. With the aid of the 3D/4D USG view the insertion side of the right ureter in to the fetal urinary bladder was easily identified and measurement of the diameter done (Figure 1). Postnatal follow of the neonate showed no progression of the megaureter and hydroureteronephrosis.

Our data show that it is feasible to visualize and measure the pericallosal artery from an early stage of gestation, and this measurement could be an indirect indication of normal corpus callosum development.

To investigate the value of a new cervical sonographic sign, called the jellyfish sign (JS), for predicting the risk of maternal morbidity in cases of abnormally invasive placenta (AIP) previa totalis. Retrospective evaluation of transvaginal (TV) and transabdominal (TA) scans performed in all singleton pregnancies with placenta previa totalis. JS, i. e. the absence of the normal linear demarcation between the placenta previa and the cervix, was evaluated by TV scans. The presence/severity of AIP and outcomes of maternal morbidity were related to this sign. JS was noted in 8/39 (20.5 %) patients. The two analyzed groups, i. e. with and without JS, were similar. The specificity of JS in AIP diagnosis, histological findings of accreta/increta/percreta, need for caesarean hysterectomy or blood loss > 2000 ml ranges between 92 % and 96.2 %, with the PPV and NPV ranging between 71.4 % and 85.7 % and 61.3 % and 80.6 %, respectively. The JS group had a significant increase in blood loss (ml) (p = 0.003), transfusions (%) (p = 0.016), red blood cells (p = 0.002) and plasma (p = 0.002), admission to an postoperative intensive care unit (ICU) (%) (p = 0.002), hospitalization length (p < 0.001) and the need of cesarean hysterectomy (%) (p < 0.001). JS was independently correlated to cesarean hysterectomy (OR 25.6; 95 % CI 2.0:322.3, p = 0.012) and blood loss > 2000 ml (OR 16.6; 95 % CI 1.5:180.1, p = 0.021) also in a logistic regression model. JS is useful in predicting the increase in maternal morbidity: massive transfusion, admission to the ICU and cesarean hysterectomy related to intraoperative bleeding in patients with a previa AIP.

Aim: To evaluate an innovative sonopelvimetry method for early prediction of obstructed labour. Methods: A prospective study was conducted in two centers. GPS-based sonopelvimetry, laborPro TM (Trig Medical Inc., Yoqneam Ilit, Israel) devise, was used prior to labour in nulliparous women at 39 -42 weeks gestation remote from labor. Maternal pelvic parameters, including inter-iliac transverse diameter, obstetric conjugate and interspinous diameter were evaluated. Fetal parameters included head station, biparietal diameter and occipitofrontal diameter. Data on delivery and outcome were collected from the electronic files. Results: The innovative use of sonopelvimetry was applied to 154 consecutive women, none of the participants complained of discomfort or complications observed. The mean time of examination was 15 + 2 minutes. Mean time of examination to delivery interval was 4.8 days (range 0 -16 days). Small interspinous diameter and high head station were the best predictors for obstructed labour. Analysis indicated 87% sensitivity and 61% specificity for birth weight fetal head station and ISD combined in predicting obstructed labour with an area under the curve of 0.77. Conclusions: Our results indicate that GPS-based sonopelvimetry combined with fetal estimated weight is a valuable tool in the risk assessment of obstructed labour. Parameters obtained by sonopelvimetry combined with birth weight may be useful.

Uterine manipulation with the transvaginal probe may be a useful solution in cases where TA-CVS is limited by difficult access to the trophoblast.
