Uroflowmetry is variably used for the assessment of men with lower urinary tract symptoms (LUTS). There is discrepancy in practice guidelines regarding recommendations for use of uroflowmetry in the initial assessment of men with LUTS. To explain this discrepancy, we systematically reviewed relevant literature to detail currently available evidence and identify evidence gaps requiring further research. PubMED, EMBASE and Medline literature databases were searched for the period between January 1970 and July 2012 to identify articles pertaining to uroflowmetry and outcomes of treatment for men with LUTS. We identified 30 studies for inclusion - none of which had a randomised design. The majority of the studies were prospective or retrospective cohort studies with some cross-sectional and observational reports. The methodology of measurement and reporting urine flow rate has been standardised by reports from the International Continence Society. The current available literature on the reproducibility of urine flow rate is inconclusive and suggests that there may be variability between measurements for a number of different reasons and that repeated tests could be of value clinically. There is also general agreement that a Qmax cut-off of 10 ml/s-1 is suggestive of bladder outlet obstruction. Despite guideline recommendations, there remains a lack of high-quality evidence from studies with robust design to fully ascertain the clinical utility of uroflowmetry and its place in the care pathway for men with LUTS. Future well-designed studies should focus on this evidence gap. © British Association of Urological Surgeons 2013.
