Aims: The primary aim of this prospective study was to examine the correlations between "The international Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF)" score and urodynamic findings in patients with urge incontinence. In addition, we aimed to observe the alterations of these parameters with antimuscarinic therapy. Methods: Between January and December 2005, patients referred to our department with urge incontinence were examined. After taking a detailed clinical history, physical examination, and urinalysis, each patient was asked to complete an ICIQ-SF questionnaire. We carried out subtracted cystometry according to a fixed protocol on all patients. Patients who were defined as detrusor overactivity incontinent were given antimuscarinic therapy for 3 months. Following treatment, filling cystometry and ICIQ-SF scoring were repeated in all patients. All pre- and post-treatment data of 18 male and 42 female patients were transferred to the SPSS 11.0 for Windows program, and statistical analyses were performed. Results: The patients' ages ranged from 28 to 70 (mean 49.8) years. We found statistically significant differences between the pre- and post-treatment parameters (mean ICIQ-SF score, first sensation, cystometric capacity, maximum detrusor pressure, compliance; P < 0.01). We found negative correlation between pre-treatment mean ICIQ-SF score and first sensation (correlation coefficient -0.266, P < 0.05) and positive correlation between pre-treatment mean ICIQSF score and maximum detrusor pressure (correlation coefficient 0.4, P < 0.01). Conclusions: ICIQ-SF scoring is a practical and reliable method for baseline and post-treatment evaluation of patients with urge incontinence. Significant correlation exists between ICIQ-SF score and urodynamic parameters.
