title: Assessment of postpartum symphysis pubis distention with 3D ultrasonography: a novel method.
abstract: OBJECTIVE
  Determining the accuracy of three-dimensional (3D) sonographic measurement of symphysis pubis (SP) distension in comparison to plain X-ray pelvic radiographs and assessing the interperformer reliability of this method.
  
  
  METHODS
  Pelvic X-ray was performed on 86 women who delivered singleton babies within 36 h of delivery then each woman was examined by 3D transperineal ultrasound imaging by two sonogrographers.
  
  
  RESULTS
  Measurements of SP with 3D transperineal ultrasonography in comparison to pelvic X-ray showed 95% limits of agreement. Interperformer reproducibility was substantial (interclass correlation coefficient 0.66-0.70) for measures of SP.
  
  
  CONCLUSIONS
  Pubic symphysis width, superior pubic ligament length, and SP height can be reliably measured with 3D ultrasonography.
