Eight weeks post contusive spinal cord injury, we built a peripheral nerve graft bridge (PNG) through the cystic cavity and treated the graft/host interface with acidic fibroblast growth factor (aFGF) and chondroitinase ABC (ChABC). This combinatorial strategy remarkably enhanced integration between host astrocytes and graft Schwann cells, allowing for robust growth, especially of catecholaminergic axons, through the graft and back into the distal spinal cord. In the absence of aFGF+ChABC fewer catecholaminergic axons entered the graft, no axons exited, and Schwann cells and astrocytes failed to integrate...

Aiva Ievins, Chet T Moritz
Paralysis due to spinal cord injury can severely limit motor function and independence. This review summarizes different approaches to electrical stimulation of the spinal cord designed to restore motor function, with a brief discussion of their origins and the current understanding of their mechanisms of action. Spinal stimulation leads to impressive improvements in motor function along with some benefits to autonomic functions such as bladder control. Nonetheless, the precise mechanisms underlying these improvements and the optimal spinal stimulation approaches for restoration of motor function are largely unknown...

OBJECTIVES: To measure the urodynamic effects of electrical co-stimulation of two individual sites in the proximal and distal urethra in persons with spinal cord injury (SCI). This work was motivated by preclinical findings that selective co-stimulation of the cranial urethral sensory nerve and the dorsal genital nerve, which innervate the proximal and distal portions of the urethra, respectively, increased reflex bladder activation and voiding efficiency. METHODS: Electrical co-stimulation of urethral afferents was conducted in persons with chronic SCI during urodynamics...

We describe an 18-year-old patient who developed back pain, rapidly ascending sensomotory deficits, bladder dysfunction, Lhermitte's sign, absent abdominal reflexes of all three levels, brisk tendon reflexes, and positive Babinski's sign. Magnetic resonance imaging of the spinal cord showed a long segment of cervical and thoracic intramedullary signal hyperintensity suggesting a longitudinally extensive transverse myelitis possibly within the course of a fast progressing ascending immune-mediated hemorrhagic myelopathy...

INTRODUCTION: Detrusor sphincter dyssynergia affects 70% to 80% of all spinal cord injury patients, resulting in increased risk of urinary tract infections (UTIs) and potential exposure to antimicrobial resistance. In Brazil, local guidelines recommend intermittent catheterization as the best method for bladder emptying, and two catheter types are available: the conventional uncoated PVC and the hydrophilic coated catheters. OBJECTIVE: To evaluate the cost-effectiveness of two types of catheters for intermittent catheterization from the perspective of the Brazilian public healthcare system...

OBJECTIVE: Lower urinary tract (LUT) dysfunction is a monumental problem affecting quality of life following neurotrauma, such as spinal cord injury (SCI). Proper function of the bladder and its associated structures depends on coordinated activity of the neuronal circuitry in the spinal cord and brain. Disconnection between the spinal and brain centers controlling the LUT causes fundamental changes in the mechanisms involved in the micturition and storage reflexes. We investigated the effects of cathodal trans-spinal direct current stimulation (c-tsDCS) of the lumbosacral spine on bladder and external urinary sphincter (EUS) functions...

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...

Sacral and peripheral neuromodulation are minimally invasive surgical procedures that are third-line therapy options for the treatment of patients with idiopathic overactive bladder syndrome. There has been interest in their efficacy in the management of neurogenic lower urinary tract dysfunction (NLUTD). Contemporary data suggest promising outcomes for urinary and bowel symptoms in carefully selected patients with spinal cord injury and/or multiple sclerosis. This article reviews the current literature regarding urinary and bowel outcomes in patients with NLUTD and also discusses contemporary studies that suggest that treatment during particular stages of neurologic injury may prevent long-term urinary sequelae...

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...

OBJECTIVES: To explore if the mechanism of the voiding dysfunction caused by spinal cord injury in rats can be improved by intravenous administration of the 5-HT2A/2C receptor agonist, DOI, and discuss whether it can be ascribed to serotonin 2A and 2C receptor up-regulation in lumbosacral cord motoneurons. MATERIALS AND METHODS: Female Sprague-Dawley rats were used, which were divided into two groups (Spinal cord injury group VS Normal control group). Under urethane anesthesia, cystometry was performed to examine the variation of urodynamic parameters before and after successive intrathecal administration of various doses of DOI into the lumbosacral cord...

Bladder compliance is a measure of distensibility. Maladies such as myelodysplasia, myelomeningocele, spinal cord injury, multiple sclerosis and obstructive uropathy are known to decrease bladder compliance. Decrease in bladder compliance is a characteristic of neurogenic bladders. The pathophysiology of bladder compliance is complex but ultimately leads to high pressure during filling and storage phases. These high pressures lead to renal impairment, incontinence, and recurrent urinary tract infections. This review presents management of poorly compliant bladders with onabotulinumtoxinA...

BACKGROUND: In patients with congenital bladder anomalies, bladder augmentation is used as a last resort to reduce intravesical pressure, but concerns about malignant transformation in augmented patients were first raised in the 1980s. The best evidence to date indicates that augmentation does not appear to increase the risk of bladder cancer in spina bifida patients. To date, oncologic outcomes from patients with spina bifida with and without augmentation have only been available in small case reports...
