title: The role of patient history in the diagnosis of urinary incontinence.
abstract: OBJECTIVE
  To assess the clinical usefulness and validity of patient history in the diagnosis of genuine stress incontinence and detrusor overactivity.
  
  
  METHODS
  A literature search was performed for publications addressing the clinical evaluation of urinary incontinence between 1975-1992.
  
  
  METHODS
  Nineteen of 29 articles during this period reported data in such a manner as to allow statistical comparison of patient history to the diagnosis based on urodynamic evaluation.
  
  
  METHODS
  Each article was assessed for the following information: inclusion and exclusion criteria, method of obtaining patient history, clinical evaluation, and diagnostic criteria. Patients in each article were classified according to their history and urodynamic diagnosis. Sensitivity, specificity, and predictive values were calculated for each article, as well as for the combined data from all articles. Combined data from all 19 articles produced a total of 3092 and 2950 patients evaluated for genuine stress incontinence and detrusor overactivity, respectively. A clinical history consistent with stress incontinence, when compared to a urodynamically based diagnosis, showed a sensitivity of 0.906, a specificity of 0.511, a positive predictive value of 0.749, and a negative predictive value of 0.771. A comparison of clinical history suggestive of an overactive detrusor and urodynamic evidence of spontaneous bladder activity revealed a sensitivity of 0.735, specificity of 0.552, positive predictive value of 0.561, and negative predictive value of 0.728.
  
  
  CONCLUSIONS
  Patient history alone is not an accurate tool in the diagnosis of genuine stress incontinence or detrusor overactivity, and should not be the sole determinant of diagnosis or treatment.
