[Value of anamnesis and the clinical stress test in the diagnosis of incontinence before gynecologic operations].
In a study comprising 471 patients the clinical value of a standardized questionnaire (Gaudenz questionnaire) and the standing clinical stress test were determined in the diagnosis of urinary incontinence. The sensitivity, specificity and predictive value of the positive and negative test of both methods were ascertained. As opposed to the final urodynamic result the clinical stress test alone showed a sensitivity of 48% (specificity 70%) in the diagnosis of genuine stress incontinence. 82% of all patients with stress incontinence were ascertained by the questionnaire, but only 54% were classified correctly as negative. The specificity of both methods combined was 94% and the predictive value 89%. On the other hand the questionnaire's predictive value in the diagnosis of urge incontinence was 9% (specificity 58%). However, the predictive value of both questionnaire and standing clinical stress test, combined, rose to 15%. Our results statistically demonstrate that the use of both methods together provides more significant information than the use of either separately.
