Placenta percreta (with bladder invasion) is a rare obstetric condition with the risk of massive intraoperative hemorrhage. In these cases, the combination of a transverse uterine fundal incision and retrograde cesarean hysterectomy could be useful to minimize maternal hemorrhage and avoid severe bladder injury.

Introduction: Placenta accreta spectrum (PAS) occurs when the placenta is pathologically adherent to the myometrium. An intact retroplacental clear space (RPCS) is a marker of normal placentation. In this study, we investigate use of the FDA-approved iron supplement ferumoxytol for contrast-enhanced MRI of the RPCS in mouse models of normal pregnancy and PAS.

Objective: To examine the prevalence and severity of postcesarean residual niche, evaluated using saline infusion sonohysterography, in an expanded cohort of women with one prior cesarean delivery and to assess the effect of uterine closure technique on the risk of placenta accreta spectrum (PAS) disorders.
Methods: This secondary analysis includes 70 patients who underwent saline infusion sonohysterography after one prior cesarean delivery. Patients were grouped according to hysterotomy closure technique: two-layer endometrium-free closure (technique A), and two- or one-layer routine closures (technique B).

Despite its critical importance, the placenta receives substantially less attention during obstetric ultrasound examinations compared to the fetus. The evaluation of the placenta is typically limited to determining its location within the uterus, particularly its relationship to the cervix. Abnormal placenta findings are the result of gross anomalies identified by chance during obstetric examinations, rather than from a systematic evaluation.

Background: Bladder injury during cesarean delivery (CD) in pregnant women with severe placenta accreta spectrum (PAS) disorders mostly occurs in the dissection of vesico-uterine space. Placental MRI may help to assess the risk of bladder injury preoperatively.
Purpose: To identify the high-risk MRI signs of bladder injury during CD in women with severe PAS.
