ABSTRACT
PURPOSE:
We attempted to find out the useful urodynamic parameters for diagnosis of bladder outlet obstruction (BOO) in women, prospectively. MATERIALS ANDMETHODS:
219 patients were available for analysis, of whom 34 were obstructed by clinical definition, 137 with stress urinary incontinence (SUI) and 34 served as a control. To predict obstruction, comparisons were made; receiver operator characteristic (ROC) curve analysis was used to determine the optimum cut-off values for peak flow rate (Qmax), detrusor pressure at maximum flow (PdetQmax) and maximal urethral closing pressure (MUCP).RESULTS:
On the basis of ROC curves between control and BOO groups, using single cut-off value at pressure-flow study, sensitivities and specificities of BOO were 97.1% and 77.9% (Qmax30cmH2O), 79.4% and 88.2% (MUCP>80cmH2O). By combined cut-off values, sensitivities and specificities of BOO were 85.3% and 92.6% (Qmax30cmH2O), and 73.5% and 94.1% (Qmax30cmH2O, and MUCP>80cmH2O).CONCLUSIONS:
Our results show that BOO might be diagnosed by the criteria of Qmax30cmH2O, and MUCP>80cmH2O.
