Pressure-flow studies of micturition.
The purpose of pressure-flow studies is to identify and quantify the abnormalities of bladder function (bladder outlet obstruction) that underlie disorders of voiding already demonstrated in simpler ways. Techniques of measurement and data quality control are of primary importance. Different methods for analyzing bladder outlet obstruction in the male like the Abrams-Griffiths nomogram and the linPURR have different aims but give broadly consistent results. Methods for assessing detrusor contractility and obstruction in the female patient are briefly discussed.
