Abstract:
Objective To evaluate the clinical value of ultrasonography detecting the poster urethrovesical angle(PUVA) in diagnosis of stress urinary incontinence(SUI).Methods From Jan.2006 to Dec.2008,the PUVA in resting phase (PUVA-r) and stress phase( PUVA-s) between with SUI and 100 healthy women were measured by color Doppler ultrasound,including 57 cases in SUI degree Ⅰ,22 cases in SUI degree Ⅱ,5 cases in SUI degree Ⅲ.Results (1) The PUVA-r and PUVA-s were (130±29) and (158±36)in SUI patients,which were significantly higher (113±19)and (115±23)in control group (P<0.01).(2) Correlation analysis showed that PUVA-s was positively correlated with the severity of SUI ( P < 0.01).(3) The area under the receiver operating characteristic curves (ROC) of PUVA-s was 0.82 (95% CI:0.76-0.89) between SUI patients and healthy women.When PUVA-s ≥ 140 ° was chosed as the cut-off value,the specificity,accuracy rate and positive predictive value in diagnosis of SUI were 84%,79%,81%,which were significantly higher than those when cut-off value of PUVA-s ≥ 120(54%,68%,62%; P < 0.05 ).Conclusion The PUVA-s in SUI patients are significantly increased and is positively correlated with the severity of SUI,which are indicated that PUVA-s ≥ 140should be used as cut-off value in diagnosis of SUI by ultrasonography.
