Symptoms analysis for the diagnosis of genuine stress incontinence.
OBJECTIVE
To determine the accuracy of an analysis of symptoms alone for the diagnosis of genuine stress incontinence.


METHODS
A comparison of results of symptoms analysis with urodynamic findings.


METHODS
A gynaecological video-urodynamic unit.


METHODS
252 consecutive patients referred for urodynamic investigations.


METHODS
A questionnaire of 20 symptoms of lower urinary tract dysfunction, midstream specimen of urine, pad testing, uroflowmetry, and video-cystourethrography.


METHODS
Using the urodynamic diagnosis as the 'gold standard', the accuracy of discriminant function analysis of symptoms was determined.


RESULTS
Symptoms analysis achieved a correct classification of 81% with a false positive rate of 16%. Use of an accumulative probability curve defines patients who fall into the equivocal range.


CONCLUSIONS
All women presenting with incontinence should undergo preoperative urodynamic studies.
