title: [Interest of saline contrast sonohysterography for the diagnosis of cesarean scar  defects].
abstract: OBJECTIVE
  To determine the interest of saline contrast sonohysterography in the evaluation of number, size and shape of cesarean scar defects in comparison with 3D-transvaginal ultrasound examination.
  
  
  METHODS
  Patients who had surgical reparation of cesarean scar defect by operative hysteroscopy were included in this retrospective study. Before surgery, they all had 3D-transvaginal ultrasound examination and saline contrast sonohysterography to establish the diagnosis. Then those two exams were compared to determine which one is better for cesarean scar defect evaluation, in terms of diagnosis and severity.
  
  
  RESULTS
  Fourteen patients were enrolled, they underwent transvaginal ultrasound and saline contrast sonohysterography before the surgery. 3D-transvaginal ultrasound examination made the diagnosis in 50% of patients with cesarean scar defect, whereas saline contrast sonohysterography enabled to detect 86% of defects, in comparison with hysteroscopy (100%). In 29% of patients, the size and depth of the cesarean scar defect was more important with saline contrast sonohysterography and hysteroscopy than expected by 3D-transvaginal ultrasound examination. After surgical repair, symptoms improvement was found in 82% of case (pain or abnormal uterine bleeding), and fertility was restored in 67%.
  
  
  CONCLUSIONS
  Saline contrast sonohysterography is better to characterize cesarean scar defects than 3D-transvaginal ultrasound, with a higher sensibility. Moreover, it evaluates more precisely the size and shape of the defect, thus severity.
