Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Residual to adjacent myometrial thickness ratio 6 weeks postpartum Ratio calculated by dividing residual myometrial thickness by adjacent myometrial thickness, measured by transvaginal ultrasound in the midsagittal plane | — |
Secondary
| Measure | Time frame |
|---|---|
| Residual myometrial thickness 6 weeks postpartum Thickness in millimeters measured from the deepest point of the scar indentation to the uterine serosal surface by transvaginal ultrasound in the midsagittal plane,Adjacent myometrial thickness 6 weeks postpartum Thickness in millimeters measured in the myometrium adjacent to the cesarean scar by transvaginal ultrasound in the midsagittal plane,Niche depth 6 weeks postpartum Vertical depth in millimeters from the endometrial surface to the deepest point of the scar indentation by transvaginal ultrasound,Niche width 6 weeks postpartum Maximum width in millimeters of the scar indentation measured in the midsagittal plane by transvaginal ultrasound,Niche depth to adjacent myometrial thickness ratio 6 weeks postpartum Ratio calculated by dividing niche depth by adjacent myometrial thickness measured by transvaginal ultrasound,Presence of cesarean scar niche 6 weeks postpartum Presence or absence of a scar indentation with a depth of at least 2 mm on transvaginal ultrasound,Operative time During cesarean delivery Time in minutes from skin incision to completion of skin closure,Estimated blood loss During cesarean delivery Estimated intraoperative blood loss in milliliters | — |
