Urodynamic studies assess the function of the bladder and bladder outlet. They are often useful in the assessment and diagnosis of patients presenting with lower urinary tract symptoms (LUTS). The evidence regarding the value and risks of invasive urodynamics remains insufficient. However, men with LUTS who are assessed by invasive urodynamics are more likely to have their management changed and less likely to undergo surgery. This review discusses the role of urodynamic diagnosis and application in the diagnosis and treatment of male LUTS.
