A mechanics--based perspective on the function of human sphincters during functional luminal imaging probe manometry [PDF]
arXiv, 2022 Functional luminal imaging probe (FLIP) is used to measure cross-sectional area (CSA) and pressure at sphincters. It consists of a catheter surrounded by a fluid filled cylindrical bag, closed on both ends. Plotting the pressure-CSA hysteresis of a sphincter during a contraction cycle, which is available through FLIP testing, offers information on its ...

Long-term Outcomes of Periurethral Sphincter Botulinum Toxin in Female Chronic Urinary Retention [PDF]
International Neurourology JournalPurpose Nonneurogenic chronic urinary retention is an uncommon problem in young female individuals, and a well characterised causes is Fowler syndrome (primary disorder of urethral sphincter relaxation). Intermittent catheterisation is often challenging,

A Method for Recording Urethral Pressure Profiles in Female Rats. [PDF]
PLoS ONE, 2015 Urethral pressure profile (UPP) and leak-point pressure (LPP) measurements as well as external urethral sphincter (EUS) electromyography (EMG) and videourodynamic analyses are the primary methods for evaluating urethral function in humans.

Urethral Closure Pressure at Stress: A Predictive Measure for the Diagnosis and Severity of Urinary Incontinence in Women [PDF]
International Neurourology Journal, 2017 Purpose Maintaining urinary continence at stress requires a competent urethral sphincter and good suburethral support. Sphincter competence is estimated by measuring the maximal urethral closure pressure at rest.

Anatomy-Aware Measurement of Segmentation Accuracy [PDF]
, 2016 Quantifying the accuracy of segmentation and manual delineation of organs, tissue types and tumors in medical images is a necessary measurement that suffers from multiple problems. One major shortcoming of all accuracy measures is that they neglect the anatomical significance or relevance of different zones within a given segment.

The distribution of information for sEMG signals in the rectal cancer treatment process [PDF]
BioSystems 176, 13 (2019), 2018 The electrical activity of external anal sphincter can be registered with surface electromyography. This signals are known to be highly complex and nonlinear. This work aims in characterisation of the information carried in the signals by harvesting the concept of information entropy. We will focus of two classical measures of the complexity.

Urethral hemangioma: How to investigate as a cause of hematuria after male sexual activities
IJU Case Reports, 2023 Introduction Urethral hemangioma is an extremely rare occurrence and is not typically considered a common cause of hematuria. Since 2000, only 22 male cases have been reported.

Sample entropy of sEMG signals at different stages of rectal cancer treatment [PDF]
Entropy 2018, 20(11), 863, 2018 Information theory provides a spectrum of nonlinear methods capable of grasping an internal structure of a signal together with an insight into its complex nature. In this work, we discuss the usefulness of the selected entropy techniques for a description of the information carried by the surface electromyography signals during colorectal cancer ...
