Re: The role of invasive and non-invasive urodynamics in male voiding lower urinary tract symptoms

摘要

Introduction: Troublesome voiding lower urinary tract symptoms (LUTS) are a common problem in men, particularly with ageing. Implicitly, management of voiding LUTS can be guided by accurate determination of underlying mechanisms, distinguishing men with voiding symptoms caused by outlet obstruction from those with reduced bladder contractility. Methods: A PubMed search of the published literature on invasive and non-invasive methods used to assess lower urinary tract function was carried out. Results: A multitude of methods have been applied to assess LUTS. Multichannel pressure flow studies (PFS) are the standard for diagnosing bladder outlet obstruction and underlying mechanisms of LUTS, though their invasive nature can be difficult to tolerate, and improved prediction of treatment outcome is disputed. Uroflowmetry and post void residual measurement are insufficient to make a definitive diagnosis.
