Primer: questionnaires versus urodynamics in the evaluation of lower urinary tract dysfunction-one, both or none?
What is the role of urodynamic assessments and have we made too much use of them? Is there a correlation between symptoms and underlying pathophysiology? These questions are addressed in this article. There are disparities in the assessment of lower urinary tract dysfunction between the accuracy of symptomatic assessment and the underlying pathophysiology. This is particularly evident with voiding symptoms, in contrast to storage symptoms, and has fuelled the debates that have resulted in the abandonment of the term 'prostatism' in favor of 'lower urinary tract symptoms', whereas the term 'overactive bladder syndrome' has been embraced as a storage symptom complex. Clearly, voiding disorders principally affect men, whilst storage disorders are more common in women. Much has been written and spoken about regarding the use of symptomatic assessment versus urodynamics in the assessment of lower urinary tract symptoms in men, whilst there has been a clearer consensus on the potential usefulness of urodynamics in the assessment of storage disorders, and so this article focuses principally on the latter topic.
