Mathematical analysis of the male urine flow rate curve for non-invasive differentiating between DU and BOO

Multivariance analysis on non-invasive urodynamic parameters for Differentiating DU with BOO in male (2018)
Presentation / Conference
Li, R., Gammie, A., Zhu, Q., & Nibouche, M. (2018, April). Multivariance analysis on non-invasive urodynamic parameters for Differentiating DU with BOO in male. Presented at United Kingdom Continence Society 2018 Conference: The First UK Pelvic Floor Summit, Telford, UK

Differentiating detrusor underactivity (DU) with bladder outlet obstruction (BOO) can only be done by pressure flow studies. Although a few parameters have been proposed for diagnosing voiding abnormalities, such as flow index1, Delta Q2, peak counti...

Non-invasive parameter for assessing urine flow rate in frequency domain to differentiate detrusor underactivity with bladder outlet obstruction in male (2017)
Presentation / Conference
Lli, R., Gammie, A., Zhu, Q., & Nibouche, M. (2017, November). Non-invasive parameter for assessing urine flow rate in frequency domain to differentiate detrusor underactivity with bladder outlet obstruction in male. Presented at Incontinence XI: The Engineering Challenge, London, England

To differentiate Detrusor underactivity (DU) with bladder outlet obstruction (BOO), we have assessed free urine flow in frequency domain, and proposed median power frequency (MPF) as a potential urodynamic indicator for diagnosing DU. As a continuat... Read More about Non-invasive parameter for assessing urine flow rate in frequency domain to differentiate detrusor underactivity with bladder outlet obstruction in male.

U-model enhanced control of nonminimum-phase dynamic systems (2016)
Presentation / Conference
Qiu, J., Zhu, Q., Nibouche, M., & Yao, Y. (2016, November). U-model enhanced control of nonminimum-phase dynamic systems. Paper presented at 8th International Conference on Modelling, Identification and Control (ICMIC-2016), Algiers, Algeria

In this study, U-model based control system design methodology is expanded into control of nonminimum-phase (NMP) dynamic systems. With U-model framework, a desired minimum-phase (MP) plant is established, which forms as a generic prototype. To achie...

A new procedure for analysis and modelling of male urine flow rate (2015)
Presentation / Conference
Li, R., Gammie, A., Zhu, Q., Nibouche, M., & Kiely, J. (2015, July). A new procedure for analysis and modelling of male urine flow rate

In the first stage studies, this paper proposes a new piecewise linear discrete time dynamic model for describing global urine flow rate profiles against time sequence. The establishment of model has been guided by physician meaningful principles and... Read More about A new procedure for analysis and modelling of male urine flow rate.

Urine flow rate shape template and intermittent flow in males
Presentation / Conference
Li, R., Gammie, A., Zhu, Q., & Nibouche, M. Urine flow rate shape template and intermittent flow in males. Presented at International Continence Society annual meeting 2018

Uroflowmetry serves as a preliminary urodynamic test for physicians to indicate the possible cause of lower urinary tract symptoms. Alongside the most researched parameter maximum flow rate (Qmax), the shape of urine flow rate curve is also reported...

Multivariate analysis of variance for maximising the diagnosing accuracy in differentiating DU from BOO in males
Presentation / Conference
Li, R., Gammie, A., Zhu, Q., & Nibouche, M. Multivariate analysis of variance for maximising the diagnosing accuracy in differentiating DU from BOO in males. Presented at International Continence Society annual meeting 2018

Detrusor underactivity (DU) and bladder outlet obstruction (BOO) bother almost half of elder men. Although the treatment is different for these two lower urinary tract symptoms, invasive pressure flow studies remains the only gold standard for diagno...

Median frequency and sum of amplitude changes in rising slope: Two potential non-invasive indicators for differentiating DU from BOO in males
Presentation / Conference
Li, R., Gammie, A., Zhu, Q., & Nibouche, M. Median frequency and sum of amplitude changes in rising slope: Two potential non-invasive indicators for differentiating DU from BOO in males. Presented at International Continence Society annual meeting 2018

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 infe...

Mathematical modelling analysis of male urine flow traces
Presentation / Conference
Li, R., Gammie, A., Zhu, Q., & Nibouche, M. Mathematical modelling analysis of male urine flow traces

Differentiating non-invasively detrusor underactivity (DU) from bladder outlet obstruction (BOO) in men remains a challenge. Invasive pressure flow studies (PFS) are still required despite many years of study. The shape of the urine free flow curve...
