Development and validity of a questionnaire for coital urinary incontinence: clinical and urodynamic analysis

To develop and validate a questionnaire (coital incontinence questionnaire-CIQ) for CI and perform clinical and urodynamic analysis of patients with CI.

A total of 414 female patients with urinary incontinence undergoing urodynamics were included in this study. All patients were evaluated with a detailed history, questionnaires, physical examination, relevant laboratory tests and urodynamics. Content, construct and convergent validity of the questionnaire were evaluated. Patients were divided into groups: with CI (group 1) and without CI (group 2).

Overall test-retest reliability coefficients of CIQ were high (r = 0.968, p = 0.01), and the internal consistency was excellent (Cronbach's alpha, 0.964). The test-retest scores did not show a statistically significant difference (p = 0.158). Approximately 34% of these women had CI. Body mass index (BMI), parity, daily incontinence episodes, daily pad counts and 1-h pad test results were higher in group 1 than group 2 (p < 0.05). Multivariate analysis revealed that a daily incontinence episode, BMI, maximum cystometric capacity and PdetQmax were statistically significant factors associated with CI. Urinary incontinence types were different between groups (p < 0.0001). Incontinence with both penetration and orgasm was the most common form of CI (54.4%), and CI severity differed significantly among the forms of CI (p = 0.007). CI negatively interferes with patients' sexual life, their relationship with their partner and quality of life in most patients.

The CIQ is a reliable, valid and useful tool for assessment of all aspects of CI in women. CI seems to be related to the severity of urinary incontinence. Further studies are needed to clarify this subject.
