Q-tip Test and Urodynamic Study

Urethral hypermobility, which can be assessed with Q-tip test, has been considered to be partly responsible for pathogenesis of women with stress urinary incontinence (SUI). Nonetheless, Q-tip test has lost favor due to patient discomfort. Thus, the purpose of this study was to search a surrogate for assessment of urethral hypermobility by correlating the Q-tip angle and the urodynamic variables in women with SUI.

About this study

All women with SUI and underwent Q-tip testing were reviewed. Patient characteristics, degree of prolapse determined by Pelvic Organ Prolapse Quantification system, Q-tip angle, the results of urodynamic studies, the Urinary Distress Inventory (UDI-6) Questionnaire and Incontinence Impact (IIQ-7) Questionnaire were reviewed from their medical records. Spearman correlation test, and univariate and multivariate backward stepwise linear regression analysis were performed as appropriate.

Treatment and study plan

Q-tip test

Diagnostic Test

A Q-Tip lubricated with anesthetic gel is inserted into the urethra, woman is then asked to cough and strain, and the angle of the Q-tip rotates is recorded.

Primary outcomes

  1. Correlations of Q-tip angle with pressure transmission ratio

    Time frame: Between 2014 and 2020

    Correlations of Q-tip angle with pressure transmission ratio at maximum urethral pressure during stress urethral pressure profile testing

Secondary outcomes

  1. Correlations of Q-tip angle with the other parameters of urodynamic studies

    Time frame: Between 2014 and 2020

    clinical and urodynamic variables include maximum flow rate, voided volume, post-void residual, voiding time, strong desire, PdetQmax, MUCP, functional profile length

  2. Correlations of Q-tip angle with pad weight

    Time frame: Between 2014 and 2020

    Correlations of Q-tip angle with 20 min pad testing result

  3. Correlations of Q-tip angle with symptoms

    Time frame: Between 2014 and 2020

    Correlations of Q-tip angle with questionnaires of urinary symptoms
