Outcome Measures

Primary Outcomes (1)

  • Rate of Niche development in the uterine cesarean section scar

    Measure number of patients that will develop uterine Niche following lower segment cesarean section

    baseline

Secondary Outcomes (6)

  • Measuring Residual myometrial thickness (RMT)

    baseline

  • Measuring depth of uterine Niche

    baseline

  • Measuring width of uterine Niche

    baseline

  • Assessment of potential risk factors for Niche development

    baseline

  • Rate of postmenstrual spotting in patients with uterine Niche

    baseline

  • +1 more secondary outcomes

Study Arms (2)

Patient having Cesarean section

Transvaginal sonography for patients having ceserean section to assess uterine Niche development and parameters

Device: Transvaginal sonography

Patient delivered vaginally

Transvaginal sonography for patients having vaginal delivery to confirm absence of uterine Niche development

Device: Transvaginal sonography

Interventions

Niche is assessed using TVS, SIS (cases only) and office hysteroscopy

Also known as: SIS, office hysteroscopy
Patient delivered vaginallyPatient having Cesarean section
