title: Measurement of urinary flow rate.
abstract: The various methods for measuring urinary flow rate from the first attempt by Rehfisch in 1897 to current techniques are described. The benefits or deficiencies of each method are considered, and it is concluded that while some of the more technically sophisticated pieces of equipment are necessary for the accurate determination of flow rates in the research laboratory, they are not necessarily the most appropriate for use in the consulting office or clinic.
