    Abstract:
    PURPOSE: Women with urodynamically documented stress urinary incontinence (SUI) and urethral hypermobility may have a higher pelvic organ prolapse quantification (POP-Q) stage according to anterior POP-Q measurements. In this study we determined if POP-Q system anterior components representing the urethrovesical junction (anterior wall point Aa/Ba) and/or POP-Q stage has a relationship with leak point pressure testing. MATERIALS AND METHODS: Of the 1,511 women who underwent video fluoro-urodynamics during 1997 to 2003 at our institution 88 with only evidence of SUI with negative Valsalva leak point pressure and positive cough leak point pressure (CLPP) were selected. RESULTS: Average patient age was 58.6 years (range 32 to 89). Of the 88 women 82 had complete POP-Q examinations available, which revealed stages 0 to III in 21 (25.61%), 20 (24.39%), 40 (48.78%) and 1 (1.22%), respectively. The association between POP-Q stage/components and positive CLPP showed no significant difference in mean positive CLPP among POP-Q stages (p = 0.178) or components (p = 0.42 to 0.97). The test for linear trend was not significant (p = 0.636) for POP-Q stages/components (p = 0.40 to 0.93). No significant difference in volume at which positive CLPP occurred was observed among POP-Q stages (p = 0.283) or components (p = 0.13 to 0.75). The proportion of patients with leakage at 200 cc did not differ significantly among POP-Q stages (p = 0.119) or components (p = 0.15 to 0.60). CONCLUSIONS: Analysis of women with urodynamic evidence of SUI with negative Valsalva leak point pressure and positive CLPP did not show any significant association with components of the POP-Q system or with POP-Q stages. Findings support that POP-Q measurements should not be interpreted as indicators of urethral hypermobility when evaluating women with SUI.
