Abstract:
Objective To observe the value of traditional pelvic floor ultrasound parameters combined with middle urethral sphincter elasticity parameters for diagnosing female stress urinary incontinence(SUI).Methods Fifty two female SUI patients(SUI group)and 45 healthy women(control group)were prospectively enrolled.Traditional pelvic floor ultrasound parameters and middle urethral sphincter elasticity parameters were compared between groups,and logistic regression analysis was performed,the efficacy of each parameter alone and their combination for diagnosing SUI was analyzed.Results Significant differences of bladder neck descent(BND),urethral rotation angle(URA),posterior urethrovesical angle(PUA),shear modulus of the middle urethral anterior wall sphincter at rest state(Q1),shear modulus of the middle urethral anterior wall sphincter under maximum Valsalva maneuver(Q2),and shear modulus of the middle urethral posterior wall sphincter at resting-state(H1)were found between groups(all P＜0.05).BND,PUA,Q1 and Q2 were all influencing factors of female SUI(all P＜0.05),with the area under the curve(AUC)for diagnosing SUI of 0.721,0.718,0.659 and 0.288,respectively.Then traditional ultrasound model,elasticity ultrasound model and combined model were constructed based on traditional pelvic floor ultrasound parameters(BND,PUA),middle urethral sphincter elasticity parameters(Q1,Q2)and their combination,respectively,with AUC for diagnosing SUI of 0.837,0.754 and 0.908,respectively.The AUC of combined model was higher than that of traditional ultrasound model,elasticity ultrasound model and each ultrasound parameter alone(all P＜0.05).Conclusion Traditional pelvic floor ultrasound parameters combined with middle urethral sphincter elasticity parameters had high value for diagnosing female SUI.
