Abstract
Between January 1983 and July 1985, 218 women underwent preliminary evaluation and urodynamic testing in our laboratory. Their symptoms and urodynamic diagnoses were compared to evaluate the ability of a patient''s history to predict the stability of the detrusor. The symptom of stress incontinence was a sensitive detector of genuine stress incontinence (100% sensitivity) but was not very specific (65.2%). The symptoms of urgency and urge incontinence were found to have limited sensitivity (77.9%) and specificity (38.7%) in the detection of detrusor instability. Even patients with isolated complaints of stress incontinence had an incidence of detrusor instability of 34.9%, whereas 76.9% of those with a history of isolated urgency and urge incontinence had detrusor instability. Three percent of patients complaining of either type of incontinence had no objective evidence of incontinence on urodynamic investigation. The results of this study demonstrate that a patient''s history is a poor predictor of the underlying cause of incontinence.
