Associação entre o escore do International Consultation on Incontinence Questionaire: Urinary Incontinence/Short Form e a Avaliação Urodinâmica em mulheres com incontinência urinária

Abstract

To evaluate the correlation between the International Consultation on Incontinence Questionnaire - Urinary Incontinence/Short Form (ICIQ-UI/SF) and Urodynamic evaluation (UE) in women with urinary incontinence (UI). Clinical data, UE and ICIQ-UI/SF scores for 358 patients from private health service were analyzed retrospectively . The correlation between ICIQ-UI/SF and urodynamic parameters was determined by Spearman's test. A ROC curve with the sensitivity and specificity of the ICIQ-UI/SF scores was utilized to establish the value of the questionnaire that would predict an altered urodynamic parameter. The χ(2) test or Fisher's exact test was used to calculate the p-value. The level of significance was 5% and the software used was SAS 9.2. Sixty-seven point three percent of the patients presented Stress UI (SUI) according to the UE (urodynamic SUI); those with SUI and Detrusor overactivity (DO) at UE represented 16.2% of the women (SUI+DO), and those with only DO at UE (DO) represented 7.3% of the women. Patients with normal UE represented 9.2% of the women. There was a significant association between ICIQ-UI/SF scores ≥14 and patients with urodynamic SUI, with or without DO. Patients with Valsava Leak Point Pressure (VLPP)≤90 cmH2O presented ICIQ-UI/SF≥15. Spearman's test showed a weak inverse correlation between ICIQ-UI/SF score and VLPP, although it did not show any correlation with maximum cystometric capacity or with bladder volume on first desire to void. There was an association between ICIQ-UI/SF score and patients with SUI, with or without DO, but no association between the score and patients with DO alone. The lower the VLPP value, the higher the ICIQ-UI/SF score. The ICIQ-UI/SF was not able to distinguish the different types of UI in the studied population.
