Prospective Evaluation of the Ultrasound Signs Proposed for the Description of Uterine Niche in Nonpregnant Women

Objectives To evaluate the new ultrasound‐based signs for the diagnosis of post‐cesarean section uterine niche in nonpregnant women. Methods We investigated prospectively a cohort of 160 consecutive women with one previous term cesarean delivery (CD) between December 2019 and 2020. All women were se...

Description
Summary:Objectives To evaluate the new ultrasound‐based signs for the diagnosis of post‐cesarean section uterine niche in nonpregnant women. Methods We investigated prospectively a cohort of 160 consecutive women with one previous term cesarean delivery (CD) between December 2019 and 2020. All women were separated into two subgroups according to different stages of labor at the time of their CD: subgroup A (n = 109; 68.1%) for elective CD and CD performed in latent labor at a cervical dilatation (≤4 cm) and subgroup B (n = 51; 31.9%); for CD performed during the active stage of labor (>4 cm). Results Overall, the incidence of a uterine niche was significantly (P
