Abstract

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.
