INTRODUCTION: Patients with anorectal malformations (ARMs) have a high incidence of genitourinary anomalies. Those with a recto-bladder neck fistula may represent a high-risk group, but their long-term urologic outcomes are poorly described. OBJECTIVE: To evaluate the clinical and urodynamic outcomes in a large cohort of patients with an ARM subtype of recto-bladder neck fistula. MATERIALS AND METHODS: A retrospective cohort study was performed of patients who had been treated for a recto-bladder neck fistula at the present institution since 2007...

PURPOSE OF REVIEW: This review examines current terminology used to define non-neurogenic chronic urinary retention (CUR), describes the pathophysiology of urinary retention, and highlights contemporary diagnostic and treatment algorithms. RECENT FINDINGS: There is no standardized definition for the condition, but volumes >300 ml are commonly used to describe CUR. It is a clinical diagnosis which does not require urodynamics. Pathophysiologic causes of CUR be from myogenic, neurogenic, bladder outlet obstruction, or a combination of these sources...

Autonomic dysreflexia is a dangerous elevation in blood pressure in people with spinal cord injury (SCI), produced by a spinally-mediated reflex activation of sympathetic vasoconstrictor neurones supplying skeletal muscle and the gut. Current dogma states that, apart from visceral inputs - such as those originating from a distended bladder or impacted colon - autonomic dysreflexia is triggered by noxious inputs below the lesion. However, while selective stimulation of small-diameter afferents in muscle or skin evokes a sustained increase in muscle sympathetic nerve activity and blood pressure, and a transient increase in skin sympathetic nerve activity and decrease in skin blood flow in able-bodied subjects, such noxious inputs have no effects on blood pressure and skin blood flow in SCI individuals...

PURPOSE: To evaluate if the injections of abobotulinum-A toxin in trigone and bladder neck/prostatic urethra in addition to detrusor provides better symptoms relief and urodynamic findings in patients with idiopathic detrusor overactivity (IDO) refractory to medical treatment. MATERIALS AND METHODS: A total of 74 patients with IDO refractory to anticholinergics received injections in detrusor, trigone and bladder neck/prostatic urethra (Group A, N=36) versus detrusor only injections (Group B, N=38) of abobotulinum-A toxin...

A female rhesus macaque developed two episodes of generalized convulsions during transcutaneous spinal cord stimulation (TSCS) and urodynamic studies under ketamine anesthesia. The seizures took place in the absence of active TSCS and bladder pressure elevation. Ketamine anesthesia remains the primary risk factor for the convulsions during these experimental procedures.

Although the combination of acute urinary retention and aseptic meningitis has not been well recognised, this combination can be referred to as meningitis-retention syndrome (MRS). We report a case of MRS with urodynamic follow-up. A 29-year-old man developed fever and headache, and after 7 days, he developed sudden urinary retention. Neurological examination indicated stiff neck, hyper-reflexes of the lower extremities. Cerebrospinal fluid examination showed mononuclear leucocytosis, increased protein level...

AIMS: The standard sensor for abdominal pressure (Pabd) measurement in urodynamics (UD) is a rectal sensor. In patients where the rectum is not available due to prior surgery or when external anal sphincter (EAS) tone is poor, rectal sensor may slip, making Pabd recording unreliable. Vaginal Pabd measurement and wireless vaginal sensors have been tried. We present our preliminary series of a novel nasogastric tube (NG) sensor for Pabd measurement. METHODS: We identified patients undergoing UD with a NG Pabd sensor from a prospectively maintained UD database of a tertiary care urological center between July 2013 and December 2016...

Following three noninferiority randomised controlled trials from different countries showing exactly the same results, it is time to translate this evidence into practice. In women undergoing primary surgery for pure stress urinary incontinence or stress-predominant mixed urinary incontinence without voiding difficulties, careful office evaluation including uroflowmetry and postvoid residual urine can replace invasive investigations such as cystometry, saving patients from embarrassment and a risk of urinary infection...

CONTEXT: Stress urinary incontinence (SUI) is a common and bothersome problem that frequently requires operative management. Over the past two decades, novel techniques have been introduced into clinical practice. With the greater variety of surgical options now available, there is an increasing focus on selecting the appropriate procedure for the individual patient based on the likely underlying pathophysiologic mechanism. OBJECTIVE: To review the methods used in the evaluation of SUI and the proposed classification systems...

INTRODUCTION AND HYPOTHESIS: The aim of this study was to establish if the management of women with overactive bladder (OAB) and patient-reported outcomes differed based on the findings of urodynamics (UDS). METHODS: A prospective, longitudinal observational study conducted in urogynaecology clinics in 22 UK hospitals participating in the Diagnostic Accuracy of Bladder Ultrasound Study (BUS). A total of 687 women with OAB symptoms or urgency-predominant mixed urinary incontinence were recruited into a diagnostic study that used UDS as the reference standard...

Intradetrusor injection of botulinum toxin A (BTX-A) is an effective option for managing patients with neurogenic detrusor overactivity (NDO) who do not respond to or tolerate oral pharmacologic agents. There is level I evidence that intradetrusor injection of onabotulinumtoxinA for refractory NDO in patients with multiple sclerosis and spinal cord injury is associated with a significantly greater achievement of goals and improved performance in urodynamic studies than placebo. Pilot studies or small case series support BTX-A for NDO in patients with Parkinson's disease and cerebrovascular accident...

More than 12,000 spinal cord injuries occur annually in the United States; more than 80% of these individuals will experience urinary tract dysfunction. Despite the clinical demand, there is a paucity of guidelines for the care of these patients. Although most urologists are familiar with dangerous urodynamic parameters and the benefits of clean intermittent catheterization, these patients face a myriad of risks that may go unrecognized. In this article, the authors discuss the impact of specific neurologic diseases on the urinary tract, examine the risks inherent to each, and determine strategies for screening, prevention, and treatment of these complications...

Many multiple sclerosis (MS) patients are affected by urinary retention. Common causes include neurogenic underactive bladder and/or bladder outlet obstruction from detrusor sphincter dyssynergia. Systemic review of contemporary MS urodynamic studies demonstrates that 53% of MS patients have detrusor overactivity, 43% have detrusor sphincter dyssynergia, and 12% have atonic bladder (12 studies, 1524 patients). There is no standard definition of MS-related urinary retention, but greater than 300 mL is a proposed threshold value for the condition based on literature review...

Parkinson's disease (PD) and atypical Parkinsonism are the second most common neurodegenerative movement disorders. Lower urinary tract dysfunction is among the most common types of associated autonomic dysfunctions. Differentiating the subtypes of PD is important for symptom management and understanding prognosis, because Lower urinary tract symptoms (LUTS) can evolve differently depending on the primary disease. LUTS are caused by storage and/or voiding dysfunctions. Urodynamics is a key investigative tool...

AIMS: Urodynamics (UDS) is widely used for the diagnosis of lower urinary tract dysfunction. Air-Charged catheters (ACC), one of the newer technologies for UDS pressure recording, has been adopted in growing numbers around the world for the past 15 years. Currently, there is a lack of published studies characterizing specific performance of the ACC. Since linearity, hysteresis, pressure drift, and frequency response are important components in characterizing accuracy for catheter-manometer systems; this study aimed to assess these four aspects in ACC...

BACKGROUND: If untreated, paediatric neurogenic bladder can cause renal failure and urinary incontinence. It is usually caused by neural tube defects such as myelomeningocele. Children with a neurogenic bladder should be monitored from birth and management should aim to preserve renal function and achieve social continence. This article outlines the management options appropriate for these children in resource-poor settings. ASSESSMENT: In most low- and middle-income countries, a general lack of awareness of the neurological effects on the urinary tract results in late presentation, usually with urological complications even when spina bifida is diagnosed early...

INTRODUCTION: There is no consensus regarding use of periprocedural antibiotics or routine urine cultures during urodynamics study (UDS) in children. At our hospital, we historically have obtained urine cultures during UDS. However, even with positive cultures, few patients require treatment. Most are successfully managed with increased hydration and frequent bladder emptying. PURPOSE: To evaluate clinical characteristics, antibiotic treatment, and outcomes in patients undergoing UDS to identify (1) risk factors for urinary tract infection (UTI) after UDS, and (2) patients who may benefit from routine urine culture...
