ABSTRACT

Objective:

To investigate the value of two-dimensional ultrasound combined with shear wave elastography (SWE) in assessing perineal body characteristics in patients with stress urinary incontinence(SUI).

Methods:

Sixty-four patients with stress urinary incontinence from December 2019 to August 2020 in the Affiliated Hospital of Qingdao University were selected as the SUI group, in addition, seventy healthy females at the same time were selected as the control group. The clinical information data were collected, two-dimensional ultrasound and SWE examination were performed to obtain the perineal body length, height, perimeter, area and the maximum(Emax) and the mean(Emean) modulus of elasticity both at the resting and maximum Valsalva conditions, ROC curve was plotted to evaluate the effectiveness of elastic modulus in evaluating perineal body in SUI.

Results:

In the resting state, the length, height, perimeter and area of perineal body in the SUI group were not significantly different from those of the control group ( P=0.590, 0.291, 0.082, 0.063). At the maximum Valsalva, the perineal body length, height, perimeter and area in the SUI group were significantly different from those of the control group ( P=0.005, 0.010, 0.001, 0.008). In the resting, the Emax and Emean values of perineal body elastic modulus in the SUI group were higher than those in the control group, but the difference was not statistically significant [(36.61±9.81)kPa vs (34.66±10.38)kPa, (27.43±9.78)kPa vs (26.97±8.85)kPa, all P>0.05]. At the maximum Valsalva, the Emax and Emean of the SUI group were significantly smaller than those of the control group, with statistically significant difference[(47.73±8.03)kPa vs (58.06±10.02)kPa, (35.78±7.89)kPa vs (44.33±9.62)kPa, all P<0.001]. The area under ROC curve of Emax and Emean at the maximum Valsalva was 0.738 and 0.647 respectively, the Emax was better than the Emean in assessment of the characteristics of perineal body in SUI patients.

Conclusions:

Two-dimensional ultrasound combined with SWE technique can quantitatively evaluate the characteristics of perineal body and provide an important imaging method for the diagnosis of SUI.
