A Data-Driven Memory-Dependent Modeling Framework for Anomalous Rheology: Application to Urinary Bladder Tissue [PDF]
arXiv, 2021 We introduce a data-driven fractional modeling framework aimed at complex materials, and particularly bio-tissues. From multi-step relaxation experiments of distinct anatomical locations of porcine urinary bladder, we identify an anomalous relaxation character, with two power-law-like behaviors for short/long long times, and nonlinearity for strains ...

Pathophysiology of Urethral Instability: Dysfunction of Smooth Urethral Musculature
Neurourology and Urodynamics, EarlyView.ABSTRACT Aims The aim of this study is to elucidate the pathophysiological mechanisms of urethral instability by analyzing and comparing cystometric data from a female individual with urethral instability and another with normal micturition. Methods Data were collected from a previous study measuring urethral pressure at three distinct points within ...

Perineal and Rectal Nerve Recruitment Order Varies During Pudendal Neurostimulator Implant Surgery
Neurourology and Urodynamics, EarlyView.ABSTRACT Introduction Pudendal nerve stimulation (PNS) is an off‐label therapy for patients experiencing pelvic pain and voiding dysfunction. The pudendal nerve has two efferent branches to the rectum and perineum. Only the rectal branch is monitored via external anal sphincter electromyography during the implant procedure to help determine the lead ...

Proof of concept: Exposing the myth of urethral atrophy after artificial urinary sphincter via assessment of circumferential recovery after capsulotomy and intraoperative pressure profiling of the pressure regulating balloon [PDF]
Investigative and Clinical Urology, 2018 Purpose: Rate of continence after artificial urinary sphincter (AUS) placement appears to decline with time. After appropriate workup to exclude inadvertent device deactivation, development of urge or overflow incontinence, and fluid loss, many assume ...

Impacts of chronic stress on urinary bladder function & recovery through modification of PACAP signaling [PDF]
, 2016 Stress can cause or contribute to bladder dysfunction though specific effects remain unclear. Individuals with interstitial cystitis (IC)/bladder pain syndrome (BPS) experience increased symptom severity with stress, including pain and increased urgency ...

Recognizing myofascial pelvic pain in the female patient with chronic pelvic pain. [PDF]
, 2012 Myofascial pelvic pain (MFPP) is a major component of chronic pelvic pain (CPP) and often is not properly identified by health care providers. The hallmark diagnostic indicator of MFPP is myofascial trigger points in the pelvic floor musculature that ...

Multifractal characteristics of external anal sphincter based on sEMG signals [PDF]
arXiv, 2017 This work presents the application of Multifractal Detrended Fluctuation Analysis for the surface electromyography signals obtained from the patients suffering from rectal cancer. The electrical activity of an external anal sphincter at different levels of medical treatment is considered.

Neurourology and Urodynamics, EarlyView.ABSTRACT Introduction The reoperation rate for artificial urinary sphincters (AUS) in men is about 25%, with poorer survival rates when reimplantation occurs after urethral erosion or infection. Data on the outcomes of second AUS implants are rare, and no data exist for third AUS implants.
