Analyse de la valeur du questionnaire ICIQ-sf et du test d'incontinence sur une heure pour le diagnostic d'incontinence urinaire objectivé par un bilan urodynamique

Aim: The aim of this study was to analyze the true value of non invasive exploration tools of urinary incontinence such as ICIQ-sf questionnaire and 1 hour pad weighting test correlated with urodynamics findings. Method and population: We performed a cross-sectional study comparing successive urodynamic testings from December 2007 to April 2010 over 120 patients (12 M, 108 F) aged from 20 to 91.5 y.old (m = 57.8; SD = 15) consulting for urinary incontinence. Each of them (120) answered to the ICIQ-sf questionnaire and the 1-hr pad weighting test was performed in 115 cases (96 %). We evaluated the correlations between ICIQ-sf scores and results of the pad test. We proceeded to a statistical likelihood ratio analysis of these two non invasive methods comparatively to the prevalence assessed by urodynamics (Receiver Operating Curve procedure). Results: The mean ICIQ-sf score was 13.5 (SD = 4.6) with a mean pad testing of 8 gm (SD = 16). As regards to urodynamic findings, the curve used to evaluate the practical value of ICIQ-sf score showed an under curve area of 0.689 (IC 95 %: [0.598-0.770]) and the curve used to evaluate the practical value of pad test showed under curve area of 0.693 (IC 95 %: [0.600-0.779]). The univariate and multivariate logistic regression model showed two independants predictors of incontinence (age: OR: 1.07; IC 95 %: [1.02-1.12]; P = 0.0032 and ICIQ-sf; OR: 1.2; IC 95 %: [1.06-1.36]; P = 0.0037). Conclusion: We concluded that the level of urodynamic diagnosis accuracy of urinary incontinence is satisfying when performing non invasive tests such as ICIQ-sf questionnaire and 1hr pad test. © Springer-Verlag France 2011.SCOPUS: ar.j
