title: Symptoms analysis for the diagnosis of genuine stress incontinence.
abstract: 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.
