Q-tip Test and Urodynamic Study

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.
