Application of Transperineal Pelvic Floor Ultrasound in Changes of Pelvic Floor Structure and Function Between Pregnant and Non-Pregnant Women

Abstract

To evaluate the changes of pelvic floor tissue structure and function between pregnant and non-pregnant women from the view of transperineal pelvic floor ultrasound. Methods: Thirty-eight cases of women with a second singleton pregnancy and thirty-two cases of women with a first singleton pregnancy underwent transperineal pelvic floor ultrasound, and their results were compared with forty-two cases of healthy nonpregnant women. Results: The differences of bladder neck descent (BND), rectal ampulla distance and levator hiatus area (LHA) among the three groups were statistically significant (P<0.05), and the differences of BND, rectal ampulla distance, LHA between the women with a second singleton pregnancy group and non-pragnent group were statistically significant (P<0.05). The BND, retrovesical angle at rest (RVA-R) and retrovesical angle underwent Valsalva maneuver (RVA-V) in the group of stress urinary incontinence (SUI) during pregnancy were larger than those in non-SUI group, with significant difference (P<0.05), especially BND and RVA-V (P = 0.00). Conclusion:Transperineal pelvic floor ultrasound has a high resolution of pelvic floor structure and function changes during pregnancy, and can dynamically evaluate pelvic floor function, providing a theoretical basis for early diagnosis and prevention of female pelvic floor dysfunction (FPFD) in subsequent pregnancies.

Electromyographic activity of pelvic floor muscles in different positions during the use an innovative vaginal educator: Cross-sectional study

“…An animal study suggests that muscle damage occurs before and persists after birth [ 30 ]. As the number of pregnancies increases, the levator hiatus area increases, worsening the function of the PFMs [ 31 ].…”

How About on the Use of Integrated Total Pelvic Floor Ultrasound in the Patients with Pelvic Floor Pathology

“…Dynamic multicompartment visualisation is achieved through TPUS, enabling visualisation of all three compartments and the anorectal angle to be measured [9]. A rectocoele can be seen during rest and accentuated during straining and may also may show the presence of trapped stool indicating obstructive defaecation.…”
