Urinary incontinence in females has been evaluated in a prospective series of 408 patients by comparing the clinical diagnosis and the subsequent urodynamic findings. The presenting symptoms or combination of symptoms were shown to have only a limited diagnostic predictive value as measured by urodynamic diagnostic criteria. The symptom of stress incontinence was a sensitive detector of genuine stress incontinence (94% sensitivity) but was not very specific (65%). The symptoms of urgency and urge incontinence were found to have limited sensitivity (62%) and specificity (47%) in the detection of detrusor instability. Even patients with isolated complaints of stress incontinence have an incidence of detrusor instability of 52%, whereas 76% of those with a history of isolated urgency and urge incontinence had detrusor instability. An urodynamic evaluation should be performed on most female patients suffering from urinary incontinence and is essential for patients who are being considered for surgery of stress incontinence.
