Application of SWE and three-dimensional energy Doppler ultrasound in evaluation of pelvic floor muscle function in postpartum women
Objective To explore the application of shear wave elastography(SWE)and three-dimensional energy Doppler ultrasound in the evaluation of pelvic floor muscle function in postpartum women.Methods A total of 77 postpartum women were divided into two groups of A[with pelvic floor dysfunction(PFD),34 cases]and B(without PFD,43 cases).SWE was used to measure Young's modulus of puborectalis at rest and systole.Three-dimensional energy Doppler ultrasound was used to measure vascular index(VI),flow index(FI),vascular flow index(VFI),peak systolic flow velocity,end-diastolic flow velocity(EDV)and resistance index(RI).Results The Young's modulus of left and right branches of puborectalis at systole was higher than that at rest in both groups(P<0.05).The Young's modulus of left and right branches of puborectalis at rest and systole was lower in group A than that in group B(P<0.05).The VI,FI,VFI and EDV were lower and RI was higher in group A than those in group B(P<0.05).Conclusion SWE and three-dimensional energy Doppler ultrasound can be used to assess the function of pelvic floor muscle in postpartum women.
