Gammie A, et al. - Authors identified signs and symptoms which demonstrated differences between men with detrusor underactivity (DU) vs those with both DU and bladder outlet obstruction (BOO). Results demonstrated that it could be possible to identify men with DU in a non-invasive way by combining symptoms, medical history and signs, that could be measured without the need for invasive urodynamics. By doing so, with sufficient specificity, men with DU could be separated from men with both DU+BOO in order to allow the use of any new non-surgical treatment modalities, such as new and effective medical therapy.
