OP08.04: Is it possible to create ultrasonographic Bishop score? Repeatability and reproducibility of potential parameters – preliminary study

Creation of a scale analogous to the Bishop's (BS) based on transvaginal ultrasound. Assessment reproducibility and repeatability individual parameters correlation with corresponding axes BS. 116 patients in third trimester pregnancy had ultrasound examination assessment five selected BS (vaginal-cervical angle [VCA], dilatation assessed by 3D [DL], progression [AoP], strain elastography software [E-Cervix] cervical length [CL]). Each parameter was twice same (n = 61) or two independent ultrasonographers 55). We calculated inter- intraobserver variability axes. All were characterised moderate excellent (table 1). significantly correlated its counterpart However, ranged across parameters, highest for CL effecement (rho -0.78), AoP station (0.63) DL (0.66). Lowest VCA position (-0.23). No between E-Cervix consistency found. Selected are high repeatability. Most has significant equivalents Further studies needed assess predictive value before IOL.
