Biometrics renal standardizes in the gestating without pathology because there are no local measurements with these parameters during pregnancy in the country. The presence of renal disorders in pregnant women with medical conditions associated is evaluated. A descriptive, prospective and correlational study review. The sample is non-probabilistic type and intentional selection consisting of 198 pregnant patients, consisting of those who attended the consultation ultrasound of Maternal Fetal Medicine Maternity "Concepcion Palacios", which were distributed in a group of 149 pregnant women had no medical pathologies associated, and a B group of 49 pregnant women if presented. A table of percentiles for renal biometry pregnant was developed by gestational age. Ages ranged from 24.2±6, 2 years and 26.2±7.1 years for groups A and B, respectively. Primigestas predominated with 36.2% in group A and 42.8% in the group B. percentiles are calculated and the corresponding tables of renal diameters pregnant were prepared by gestational age. The sonographic findings reveal that diameters of renal morphology in pregnant women without renal disease in each of the trimesters of pregnancy.

Methods: Thirty fetuses were included in the study. Cephalic volumes were twice acquired prospectively. Measurements of the biparietal diameter (BPD) and head circumference (HC) were performed from volumes by two experienced sonographers and by SmartPlane ® software. These measurements were both compared to those obtained with automated calipers positioning and to conventional 2D measurements. Means and SD of the differences between the series of measurements were calculated. Intra and interobserver reproducibilities were assessed using intraclass correlation coefficient (ICC). Bland & Altmann plots were used to evaluate the agreement between the series of measurements. Results: Intra and interobserver reproducibilities were high regardless of the measurement technique (ICC> 0.99 for both). The maximum average difference between two series of measurements was 1.12 mm +/-0.86 and 4.02 mm +/-2.8 for the biparietal diameter and the head circumference, respectively. For these two parameters, the agreement between software and operators was very high (95% of the observed differences were <2.5 mm and <4 mm for the BPD and the HC respectively). Conclusions: Agreement between measurements performed from 3D volumes by software and conventional 2D measurements is high and comparable to agreement observed between semi-automatic and conventional 2D measurements. Reproducibility of these measurements is similar to those observed in experienced sonographers. EP22.21Magnetic resonance in fetal cerebral lesions
