Abstract：Objective: To explore the value of transperineal ultrasonography in female patients with stress urinary incontinence. Methods: Seventy-nine patients with stress urinary incontinence(40 patients in the mild group and 39 in the moderate to severe group) and 41 patients without SUI or POP in the control group were included from August 2013 to March 2014 in the affiliated hospital of Hebei United University. Perineal ultrasonography was performed to measure posteriorurethra-vesical angle(α) at rest and distance of bladder neck mobility(Mu) after Valsalva action. After taking and storing the images under such conditions, the rotation angle of vesical neck(θ) and the down-moving distance of bladder(X) were all measured. Results: The mean distance of Mu and angels of θ and α were found to be statistically significant in the three groups(P<0.05), which were positively correlated with the severity of SUI(Mu, θ and α values were 0.861, 0.750, 0.619, P<0.05). There was significant difference for mean distance X between the SUI group and control group(P<0.05), but no difference between the mild group and the moderate to severe group. Conclusion: Perineal ultrasonography can play an important role in diagnosing patients with SUI by providing intuitive and clear changes of the anatomy and function of pelvic floor.
