Parameters such as detrusor opening pressure (p<jats:sub>det.open<\/jats:sub>), maximum detrusor pressure (p<jats:sub>det.max<\/jats:sub>), minimum voiding pressure (p<jats:sub>det.min.void<\/jats:sub>), and detrusor pressure at maximum flow rate (P<jats:sub>det.Qmax<\/jats:sub>) separate obstructed from nonobstructed patients to some extent, but two nomograms, the Abrams\u2010Griffiths nomogram and the linearized passive urethral resistance relation (LinPURR), are more accepted for this purpose, along with the urethral resistance algorithm. In this retrospective, methodologic study, we evaluated the properties of these parameters with regard to test\u2010retest reproducibility and ability to detect a moderate (pharmacologic) and a pronounced (surgical) relief of bladder outlet obstruction. We studied the pressure\u2010flow charts of 42 patients who underwent 24 weeks of androgen suppressive therapy, 42 corresponding patients who received placebo, and 30 patients who had prostate surgery. The patients performed repeat void pressure\u2010flow examinations before and after treatment or placebo. The various parameters were compared. Among the bladder pressure parameters, P<jats:sub>det.Qmax<\/jats:sub> seemed to have some advantages, supporting the belief that it is the most relevant detrusor pressure parameter to include in nomograms to quantify BOO. In assessment of a large decrease in urethral resistance, such as after TURp, resistance parameters that are based on maximum flow rate as well as detrusor pressure are preferable. Neurourol.
