Reproducibility of non-invasive urodynamics, using the cuff-uroflow, for the diagnosis of bladder outlet obstruction in males.

Objective: To determine the repeatability of the parameters obtained from non-invasive urodynamics, using the cuff-uroflow, for the diagnosis of bladder outlet obstruction.

Material And Methods: The study was carried out in a consecutive series of 34 males with functional urinary tract symptoms. The test-retest reproducibility of isometric pressure, flow in response to isovolumetric pressure and the energy transfer ratio obtained at two different times using the cuff-uroflow method was determined.
