PURPOSE: To clarify the association between clinically defined simple stress urinary incontinence (SUI) symptoms and urodynamic SUI, we examined the relationship between Valsalva leak point pressure (VLPP) as measured by the Q-tip test and Stamey grade in simple female SUI. METHODS: Two hundred grade I or II female SUI patients with SUI symptom were examined by reviewing medical history; physical examination; urethral mobility as assessed by Q-tip test; stress test; and cystometry, including VLPP measurement. On the basis of the VLPP, patients were classified into urethral hypermobility [UH, subdivided into anatomical incontinence (AI) and equivocal incontinence (EI)] or intrinsic sphincter deficiency groups for analysis of the relationship between VLPP and Stamey grade and Q-tip angle. RESULTS: Seventy-eight patients were included, and the mean patient age was 54 ± 7.5 years, mean SUI symptom duration 2.8 years (range 0.5-6 years), mean VLPP 103.6 ± 18.4 cm H2O, and mean Q-tip angle 28.6° ± 7.2°. Fifty-three patients were categorized as Stamey grade I, 25 as Stamey grade II, 51 as AI, and 27 as EI. VLPP was found to be negatively correlated with Q-tip angle (Rs = -0.798, Y = -0.313X + 60.95, P < 0.001), and classifications of VLPP and Stamey grade have positive correlation (χ (2) = 4.9130, P = 0.0267). CONCLUSIONS: In simple female SUI, VLPP is associated with the Q-tip angle and Stamey grade, which may help to reduce some of urodynamic items.
