Abstract:
Objective To investigate the value of urodynamic parameters in diagnosing female bladder outlet obstruction.Methods By follow-up investigation,36 out of 54 patients who underwent transurethral vesical neck incision for female bladder outlet obstruction(FBOO)were proven to achieve good therapeutic efficacy,so the clinical diagnosis as FBOO made before treatment was regarded as correct,as FBOO group.Anther 29 asymptomatic healthy female subjects were selected as controls.ROC curve was used to analyze the urodynamic parameters.Results The area under curve,cutoff for diagnosis and their sensitivity and specificity of the parameters were as follows:Q_ max:AUC=0.823,Q_ max≤15 ml/s(SEN=87%,SPE=81%);PdetQ_ max:AUC=0.826,PdetQ_ max≥28.5 cmH_ 2O(SEN=76%,SPE=72%);A-G value:AUC=0.922,A-G value≥1.1(SEN=86%,SPE=86%).Conclusion When Q_ max≤15 ml/s,PdetQ_ max≥28.5 cmH_ 2O and A-G value≥1.1,FBOO is likely to occur in female.
