Standardised transvaginal ultrasound evaluation of a niche in the non-pregnant uterus. a. Measured in the transversal plane: niche width (1); b. Measured in the sagittal plane: niche length (2), niche depth (from cervical canal until apex of the niche) (3), residual myometrium thickness (from deepest part of the niche until the serosa) (4), adjacent myometrium thickness (myometrium thickness close to base of the niche) (5), distance from apex of the niche to vesico-vaginal fold (see c) (6); c. Measuring the niche relatively to the vesico-vaginal fold in the sagittal plane: positive value (green arrow, in mm) or negative value (red arrow, in mm)
