@article { , title = {Median frequency and sum of amplitude changes in rising slope: Two potential non-invasive indicators for differentiating DU from BOO in males}, abstract = {It remains a challenge to non-invasively differentiate detrusor underactivity (DU) from bladder outlet obstruction (BOO) in males, and the gold standard is pressure flow studies, which is invasive, relatively expensive and may cause bleeding and infection. This novel study aims to non-invasively differentiate DU from BOO in males by analysing urine flow rate curves in the frequency domain. The hypothesis is that underactive patients may perform more abdominal straining than obstructed patients during micturition due to their underactive detrusor. Thus, it is possible to analyse the urine flow rate in frequency domain and derive non-invasive parameters for differentiating these two groups, as abdominal muscle strains in a different frequency range comparing with detrusor contraction.}, doi = {10.1002/nau.23760}, issn = {0733-2467}, issue = {S5}, journal = {Neurology and Urodynamics}, pages = {S248-S249}, publicationstatus = {Published}, publisher = {Wiley}, url = {https://uwe-repository.worktribe.com/output/864818}, volume = {37}, keyword = {Engineering Modelling and Simulation Research Group, frequency analysis of flow rate, non-invasive indicator}, year = {2018}, author = {Li, Rui and Gammie, Andrew and Zhu, Quanmin and Nibouche, Mokhtar} }
