Unravelling detrusor underactivity: Development of a bladder outlet resistanceBladder contractility nomogram for adult male patients with lower urinary tract symptoms

摘要

AimsVoiding dysfunction in adult men may be caused by bladder outlet obstruction (BOO) and/or detrusor underactivity (DU). Until now, it is only possible to classify BOO and DU by pressure-flow analysis. Low values of the maximum Watts factor (W-max) indicate DU but thresholds for the diagnosis have not been established. Purpose of this study was to construct a nomogram using bladder outlet resistance and detrusor contractility in order to classify BOO and DU simultaneously.
