Dyssynergia

Detrusor sphincter dyssynergia (DSD) is defined as a detrusor contraction concurrent with an involuntary contraction of the urethral and/or periurethral striated muscles typically occurring in a patient with a spinal cord lesion above the sacral cord. Consequently, high urethral closure pressures during the detrusor contraction leads to high intravesical voiding pressure and large postvoid residuals, which can lead to significant complications in up to 50% of patients if DSD is not treated and followed-up regularly...

OBJECTIVE: To determine whether duration of detrusor overactivity (DO) during a cystometric study is an independent predictive factor of upper urinary tract deterioration (UUTD) in patients with traumatic spinal cord injury (TSCI). STUDY DESIGN: Retrospective cohort study. SETTING: A rehabilitation facility in Chiang Mai, Thailand. METHODS: Data were obtained from medical records of patients who underwent cystometric evaluation at 6-12 months after TSCI...

PURPOSE: Neurogenic lower urinary tract dysfunction (NLUTD) is common in patients with neurological lesions in the central nervous system (CNS). Medical treatment usually cannot adequately relieve NLUTD. This study reported the real-life treatment outcome of botulinum toxin A (BoNT-A) for overactive bladders (OAB) and voiding dysfunction in patients with CNS lesions. METHODS: We retrospectively analyzed the first-time treatment outcome of 74 patients who received detrusor 100 U BoNT-A for OAB and 45 patients who received a urethral sphincter 100 U BoNT-A injection for voiding dysfunction...

BACKGROUND AND AIMS: Abdominal distention results from abdominophrenic dyssynergia (diaphragmatic contraction and abdominal wall relaxation) in patients with disorders of the gut-brain interaction. This study aimed to validate a simple biofeedback procedure, guided by abdominothoracic wall motion, for treating abdominal distension. METHODS: In this randomized, parallel, placebo-controlled trial, 42 consecutive patients (36 women and 6 men; age, 17-64 years) with meal-triggered visible abdominal distension were recruited...

OBJECTIVES: Wolfram syndrome is characterised by insulin-dependent diabetes (IDDM), diabetes insipidus (DI), optic atrophy, sensorineural deafness and neurocognitive disorders. The DIDMOAD acronym has been recently modified to DIDMOAUD suggesting the rising awareness of the prevalence of urinary tract dysfunction (UD). End stage renal disease is the commonest cause of mortality in Wolfram syndrome. We present a case series with main objective of long term follow up in four children having Wolfram syndrome with evaluation of their urodynamic profile...

BACKGROUND/AIMS: Functional anorectal pain is one of several types of functional anorectal disorders. In this study, we compared the effectiveness of acupuncture (intervention) and biofeedback (control) as treatment for patients with functional anorectal pain. MATERIALS AND METHODS: This prospective, single-center, randomized, and comparative study examined 68 patients with functional anorectal pain who were recruited from June 2017 to January 2019 at the Nanjing Hospital of Chinese Medicine Affiliated to Nanjing University of Chinese Medicine...

BACKGROUND/AIMS: Patients with chronic constipation (CC) exhibit symptoms and functional abnormalities upon testing, but their relationship to age and gender is unclear. We assessed age- and gender-related differences in symptoms, colon transit time, and anorectal motility, sensation, and expulsion. PATIENTS AND METHODS: Retrospective, post hoc data analysis of patients with CC, who underwent Wireless Motility Capsule (WMC), High-Resolution Anorectal Manometry (HR-ARM), Balloon Expulsion Test (BET) and Rectal Sensory Testing (RST)...

BACKGROUND AND AIMS: Up to 50% of patients with Parkinson disease have constipation (PD-C), but the prevalence of defecatory disorders caused by rectoanal dyscoordination in PD-C is unknown. We aimed to compare anorectal function of patients with PD-C versus idiopathic chronic constipation (CC). METHODS: Anorectal pressures, rectal sensation, and rectal balloon expulsion time (BET) were measured with high-resolution anorectal manometry (HR-ARM) in patients with PD-C and control patients with CC, matched for age and sex...

INTRODUCTION: Functional bladder outlet obstruction (BOO) in women is postulated to be caused by pelvic floor muscle (PFM) dyssynergia or increased tone. The aim of the present review was to investigate the effect of PFM relaxation training on PFM tone and female BOO symptoms. MATERIALS AND METHODS: This was a narrative review using an open search strategy on PubMed with the search terms "Bladder outlet obstruction" AND "female" AND ("pelvic floor muscles" OR "Kegel")...

Dyssynergic defecation, defined as the incoordination of rectoanal and abdominal muscles and the pelvic floor which are necessary for the appropriate relaxation, is characterized by paradoxical anal contraction, inadequate anal relaxation, or abnormal rectal propulsion; it is considered a cause of refractory primary constipation. The prevalence of dyssynergic defecation in the pediatric age is still little known. The studies that have evaluated the defecation dynamics through anorectal manometry suggest that 36...

Spinal cord injury often results in chronic loss of micturition control, which is featured by bladder hyperreflexia and detrusor sphincter dyssynergia. Previous studies showed that treatment of capsaicin reduces non-voiding bladder contractions in multiple animal injury models and human patients. However, its underlying neural mechanisms remain largely unknown. Here, by injecting a RetroAAV into the bladder wall, we specifically targeted TRPV1+ , a capsaicin receptor, bladder afferent neurons. Morphometric analysis revealed borderline increase of the soma size and significant spinal axon sprouting of TRPV1+ bladder afferent neurons post a complete T8 spinal cord crush...

Fecal incontinence (FI) is often underreported and underestimated in men. Our aims were to clarify the causes and the physiological characteristics of FI in men and to underline the differences between etiological and physiological factors in men and women diagnosed with FI. The study cohort encompassed 200 men and 200 women who underwent anatomical and physiological evaluation for FI in a tertiary referral center specializing in pelvic floor disorders. All patients underwent endoanal ultrasound and anorectal manometry...

BACKGROUND: Defecation dysfunction may contribute to chronic constipation (CC), but the impact of obesity on anorectal physiology in CC remains unclear. We aimed to evaluate the relationship between obesity and anorectal function on physiologic testing in patients presenting with CC. METHODS: This was a retrospective cohort study of consecutive adults who underwent high resolution anorectal manometry (HRAM) at a tertiary center for CC. Patient demographics, clinical history, surgical/obstetric history, medications, and HRAM results were reviewed...

BACKGROUND: Digital rectal examination should be performed prior to anorectal manometry; however, real-world data is lacking. AIMS: Characterize real world rates of digital rectal and their sensitivity for detecting dyssynergia compared to anorectal manometry and balloon expulsion test. METHODS: A retrospective single-center study was conducted to examine all patients who underwent anorectal manometry for chronic constipation between 2021 and 2022 at one tertiary center with motility expertise...

BACKGROUND AND AIMS: The primary method for assessing anorectal function is high resolution anorectal manometry (HRAM). It is a useful tool in the diagnosis of different anorectal functional disorders such as fecal incontinence or dyssynergia. The aim of the present study was to propose a new set of normal values to be used in practice for East-European individuals, as it was proven that the results are highly influenced by race and sociocultural status. METHODS: We conducted a study based on anorectal manometric values of healthy volunteers analyzed at Clinic Fundeni Institute, Bucharest, Romania, between 2017 and 2022...

INTRODUCTION: The prevalence, formal definition, and diagnostic criteria of bladder outlet obstruction in owmen have not been clearly defined. METHODS: This is a literature review of the definition of BOO in women, its prevalence, as well as its differential diagnosis. RESULTS: The main causes of BOO in women are divided into functional and anatomic conditions. Functional etiologies include detrusor external sphincter dyssynergia, dysfunctional voiding, Fowler's syndrome, and primary bladder neck obstruction...

Chilaiditi sign is defined as the interposition of the colon or small intestine between the liver and the right diaphragm in the absence of symptoms. Chilaiditi syndrome refers to the condition where the Chilaiditi sign is associated with symptoms including abdominal pain. In this series, we present the cases of two pre-pubescent patients with these rare conditions.  A 10-year-old female with a history of autism, IgA deficiency, and constipation presented for gastrointestinal studies due to weight loss and constipation...

OBJECTIVES: Several central nervous system (CNS) centers affect muscle groups of the lower urinary tract (LUT) and anorectal tract (ART) via autonomic and somatic pathways, working in different modes (storage or expulsion). Hence spinal cord dysfunction can affect the LUT and ART by several possible mechanisms. METHODS: This review reports the discussions of a workshop at the 2023 meeting of the International Consultation on Incontinence Research Society, which reviewed uncertainties and research priorities of spinal dysfunction...

Botulinum toxin-A (BoNT-A) injections into the external urethral sphincter are an established therapeutic procedure for reducing bladder outlet obstruction in patients with detrusor sphincter dyssynergia (DSD) due to spinal cord injury (SCI). Given the paucity of data on patients with DSD but without SCI, we aimed to assess the efficacy of intrasphincteric BoNT-A injections in this cohort. For this retrospective study, we screened all patients who underwent their first intrasphincteric BoNT-A injection at our institution between 2015 and 2021...

BACKGROUND AND PURPOSE: Lower urinary tract symptoms (LUTS) significantly affect quality of life (QoL) of multiple sclerosis (MS) patients, and pharmacotherapy has limited efficacy. We investigated efficacy and safety of the implantable StimRouter neuromodulation system for treating refractory LUTS in MS. METHODS: This prospective, single-center, clinical trial was conducted at the Multiple Sclerosis Center of Lugano, Switzerland, involving MS patients treated with self-administered percutaneous tibial nerve stimulation delivered by StimRouter over 24 weeks...
