Abstract：Objective To study the correlation of morphological and functional characteristics of pelvic diaphragm hiatus in
postpartum women with stress urinaryincontinence (SUI) by transperineal three-dimensional ultrasonography. Methods From
January 2015 to June 2017, 118 postpartum women underwent transperineal 3D ultrasound investigation, including 46 postpartum
women with SUI and the other 72 postpartum women without SUI. In the mean time, 60 normal nulliparous healthy women
without SUI and constipation were chosen as control group. The perimeter and area of pelvic diaphragm hiatus were measured at
rest, on maximum pelvic floor contraction and maximum Valsalva by 3D ultrasound, respectively. The mobility of urethrovesical
junction was measured on maximum Valsalva. Results The perimeter and area of pelvic diaphragm hiatus were significantly
increased than those in control group, at rest, on maximum pelvic floor contraction and maximum Valsalva respectively. While the
mobility of urethrovesical junction (URJ) was higher than that in control group on maximum Valsalva. The perimeter and area of
pelvic diaphragm hiatus in postpartum women with SUI were increased than those without SUI at three maneuvers, respectively,
the mobility of URJ was higher than that without SUI on maximum Valsalva. Conclusion Transperineal three-dimensional
ultrasonography has great value for pelvic diaphragm hiatus change in postpartum women ,especially those with SUI.
