Abstract:
Objective To observe the value of middle urethral motion and sphincter elasticity for diagnosing female stress urinary incontinence(SUI).Methods Totally 97 female patients,including 52 with SUI(SUI group)and 45 without SUI(control group)were prospectively enrolled.Pelvic floor ultrasound was performed under resting state and the maximum Valsalva maneuver,respectively,and bladder neck mobility(BND),upper-lower mobility of middle urethra(UMupper-lower),anterior-posterior mobility of middle urethra(UM anterior-posterior),elasticity parameter of the anterior wall of middle urethral sphincter(ΔEanterior wall),as well as elasticity parameter of the posterior wall of middle urethral sphincter(ΔEposterior wall)were measured.Patients'general data and the above ultrasound parameters were compared between groups,and the efficacy of them for diagnosing SUI was analyzed.Results Significant differences of BND,UM upper-lower,ΔEanterior wall and ΔEposterior wall,of also the proportion of lateral episiotomy history were found between groups(all P＜0.05).Among them,UMupper-lower,ΔEanterior wall and ΔEposterior wall were all correlated with female SUI(rs=0.231,-0.533,-0.428,all P＜0.05).The area under the curve(AUC)of UMupper-lower,ΔEanterior wall,ΔEposterior wall and their combination for diagnosing SUI was 0.634,0.820,0.748 and 0.867,respectively.The AUC of the combination was significantly higher than that of each parameter alone(all P＜0.001).Conclusion The combination of middle urethral motion and sphincter elasticity was helpful for diagnosing female SUI.
