Predictive value of clinical evaluation of stress urinary incontinence: a summary of the published literature.
Our objective was to evaluate the symptom and sign of stress incontinence in predicting the presence of urodynamically diagnosed genuine stress incontinence (GSI). The study was a computation of the sensitivity and predictive values from the published literature (1975-1998), evaluating the history and/or physical examination for the diagnosis of GSI, with calculation of efficacy variables. Results show that the isolated symptom of stress incontinence has a positive predictive value (PPV) of 56% for the diagnosis of pure GSI and 79% for GSI with additional abnormalities. The PPV of stress incontinence in association with other symptoms is 77% in detecting GSI (with or without additional abnormalities). A positive cough stress test has a PPV of 55% for detecting pure GSI and 91% for the mixed condition (GSI plus additional diagnosis). When isolated, the symptom or the sign of stress incontinence is a poor predictor of GSI. In combination, the prediction may be more promising.
