Abstract
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. Anatomic causes can be further divided into extrinsinc and intrinsic conditions. Intrinsic etiologies include urethral stricture and urethral diverticula, whereas extrinsic causes comprise pelvic organ prolapse, post anti-incontinence surgery, and Skene's gland cyst or abscess. CONCLUSIONS There are multiple etiologies to BOO in women, and this condition is most probably underdiagnosed, owing to a lack of consensus for a standard definition.

Front Neurol 2023; 14:1282580. [PMID: 38046590 PMCID: PMC10693342 DOI: 10.3389/fneur.2023.1282580] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 10/20/2023] [Indexed: 12/05/2023] Open
Abstract
Background The evidence for the effectiveness of electroacupuncture (EA) for post-stroke urinary incontinence (PSUI) patients remains unclear. Therefore, the purpose of this systematic review and meta-analysis was to assess the efficacy of EA for PSUI. Methods and analysis Eight English and Chinese databases were searched from their inception until 1 August 2023 to collect randomized controlled trials (RCTs) that investigated the effect of EA on PSUI. Two reviewers independently selected studies that met the eligibility criteria, extracted the necessary data, and assessed the risk of bias for included studies using Cochrane Handbook version 5.1.0. Meta-analysis was performed using Review Manager software (version 5.4.1). Publication bias detection was conducted using STATA (version 16.0). Sequential analysis was performed using TSA 0.9.5.10 Beta. The Grading of Recommendations Assessment, Development, and Evaluation System (GRADE) was used for assessing the certainty of evidence. Results We included 15 RCTs involving a total of 1,414 patients. The narrative analysis revealed that compared with sham EA, genuine EA exhibited greater efficacy in reducing occurrences of 24-h urinary incontinence while also enhancing maximum cystometric capacity (MCC). Moreover, this effect remained significant even during the 3-month follow-up period. Fourteen studies were encompassed within the quantitative analysis. In contrast to active interventions, EA did not yield an improvement in the responder rate (RR 1.53, 95% CI 0.61 to 3.80, p = 0.36). When compared with basic treatments, the combination of EA with them led to a reduction in 24-h urinary incontinence occurrences (MD -0.56, 95% CI -0.60 to -0.52, p < 0.00001), an improvement in MCC (MD 43.23, 95% CI 28.86 to 57.60, p < 0.00001), and a decrease in residual urine volume (RUV; MD -19.99, 95% CI -29.75 to -10.23, p < 0.0001). However, it did not lead to an increase in the responder rate (RR 1.39, 95% CI 0.88 to 2.20, p = 0.16). In comparison to basic treatments combined with active interventions, the amalgamation of EA and them led to an increase in the responder rate (RR 1.24, 95% CI 1.14 to 1.35, p < 0.00001), a reduction in 24-h urinary incontinence occurrences (MD -2.90, 95% CI -5.26 to -0.55, p = 0.02), a decrease in International Consultation on Incontinence Questionnaire-Short Form scores, and an improvement in both MCC (MD 42.11, 95% CI 23.26 to 60.96, p < 0.0001) and RUV (MD 42.11, 95% CI 23.26 to 60.96, p < 0.0001). Furthermore, all reported adverse effects associated with EA were mild. The trial sequential analysis suggested that a sufficient sample size was available to yield results. However, the level of evidence was predominantly assessed as low or very low. Conclusion Electroacupuncture improved post-stroke urinary incontinence with no serious adverse effects. Caution is warranted due to methodological issues, and more high-quality studies are required to confirm its efficacy and safety.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023449599, Identifier CRD42023449599.

Abstract
Multiple system atrophy (MSA) is a sporadic, fatal, and rapidly progressive neurodegenerative disease of unknown etiology that is clinically characterized by autonomic failure, parkinsonism, cerebellar ataxia, and pyramidal signs in any combination. Early onset and extensive autonomic dysfunction, including cardiovascular dysfunction characterized by orthostatic hypotension (OH) and supine hypertension, urinary dysfunction characterized by overactive bladder and incomplete bladder emptying, sexual dysfunction characterized by sexual desire deficiency and erectile dysfunction, and gastrointestinal dysfunction characterized by delayed gastric emptying and constipation, are the main features of MSA. Autonomic dysfunction greatly reduces quality of life and increases mortality. Therefore, early diagnosis and intervention are urgently needed to benefit MSA patients. In this review, we aim to discuss the systematic treatment of autonomic dysfunction in MSA, and focus on the current methods, starting from non-pharmacological methods, such as patient education, psychotherapy, diet change, surgery, and neuromodulation, to various drug treatments targeting autonomic nerve and its projection fibers. In addition, we also draw attention to the interactions among various treatments, and introduce novel methods proposed in recent years, such as gene therapy, stem cell therapy, and neural prosthesis implantation. Furthermore, we elaborate on the specific targets and mechanisms of action of various drugs. We would like to call for large-scale research to determine the efficacy of these methods in the future. Finally, we point out that studies on the pathogenesis of MSA and pathophysiological mechanisms of various autonomic dysfunction would also contribute to the development of new promising treatments and concepts.

An evidence-based approach to the recovery of bladder and bowel function after pediatric spinal cord injury. J Clin Neurosci 2023; 118:103-108. [PMID: 39491976 DOI: 10.1016/j.jocn.2023.10.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 10/18/2023] [Accepted: 10/23/2023] [Indexed: 11/05/2024]
Abstract
INTRODUCTION Bladder dysfunction and associated complications of the urinary system negatively impact the quality of life in children living with spinal cord injury (SCI). Pediatric lower urinary tract deficits include bladder over-activity, inefficient emptying, decreased compliance, and incontinence. Recent evidence in adults with SCI indicates significant improvements in bladder capacity and detrusor pressure following participation in an activity-based recovery locomotor training (ABR-LT) rehabilitative program. Additionally, anecdotal self-reports from parents in our Pediatric NeuroRecovery Program reference changes in bladder function, ranging from awareness of bladder fullness to gains in voluntary control while undergoing ABR-LT. CASE PRESENTATION In a within-subjects repeated measures study, we investigated the effect of ABR-LT on bladder function in three children (ages: 2.5, 3, and 6 years) who sustained upper motor neuron SCI. Each child received at least 60 sessions of ABR-LT (5x/week) for 12-14 weeks. Bladder function was assessed via urodynamics and the Common Data Elements questionnaires. Awareness of bladder filling during cystometry was present in all children and detrusor leak point pressure (LPP) was reduced post-ABR-LT relative to pre-training. A decrease in LPP after locomotor training was observed in all three participants. One out of the three participants had substantial improvements in bladder capacity post-ABR-LT and experienced less bowel incontinence following training. DISCUSSION Like our evidence in adults, the changes in bladder function suggest an interaction between lumbosacral networks regulating spinal reflex control of bladder filling, voiding, and afferent input (including potential descending supraspinal commands) and those activated by ABR-LT. Locomotor training may be associated with increased bladder capacity, enhanced perception of bladder filling, and decreased LPP as well as improvements in bowel control in pediatric SCI. This research suggests that children and adolescents with traumatic SCI could experience dynamic improvements in bladder and bowel function with the aid of various therapies. Studies assessing the durability of training on the recovery of bladder and bowel dysfunction in children with SCI are needed.

Neurogenic Disorders and the Lower Urinary Tract Dysfunction: Proposed Approach for the Gynecologist. Reprod Sci 2023; 30:2087-2091. [PMID: 36973580 DOI: 10.1007/s43032-023-01213-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Accepted: 03/09/2023] [Indexed: 03/29/2023]
Abstract
BACKGROUND The scenario of the patient with neuropathies, which are related to urinary disorders, impacts the quality of life. Symptoms can lead to social isolation, impair activities of daily living, and shorten life expectancy. This study aims to make a practical and integrative review of current recommendations for the urogynecological approach of patients with neuropathy and urinary dysfunction. METHODS The authors searched for data on combinations of the terms "lower urinary tract symptoms" AND "neurogenic voiding dysfunction" from January 2012 to January 2022 in the following scientific databases: PUBMED, MEDLINE, EMBASE, and The Cochrane Library. INCLUSION CRITERIA randomized clinical trials, protocols from specialized societies and articles before that period, and according to clinical relevance. EXCLUSION CRITERIA case series or reports, expert opinions not endorsed by medical societies in the area. RESULTS From the 25 studies mentioned, 09 studies were selected according to pre-established criteria and qualitative analysis of relevance. The authors add 2 references for relevance in the area of urogynecology and neurological diseases. According to the selected scientific references, the main neuropathies that can cause urinary dysfunction are CNS injuries such as stroke, spinal cord injury, meningomyelocele, and amyotrophic lateral sclerosis. Ten steps below were compiled to facilitate the gynecological approach, according to the researched literature. CONCLUSION It is important for the medical assistant to pay close attention to careful anamnesis and post-emptying urinary residual volume. The treatment in general addresses greater fluid intake, maneuvers to favor bladder emptying, medications, and/or intermittent self-catheterization. The approach of a multidisciplinary team can make a difference in the patient's prognosis and quality of life.

Intrathecal Baclofen for Spasticity: Is There an Effect on Bladder Function? Report of Three Cases and Review of the Literature. Biomedicines 2022; 10:biomedicines10123266. [PMID: 36552022 PMCID: PMC9775073 DOI: 10.3390/biomedicines10123266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 12/07/2022] [Accepted: 12/13/2022] [Indexed: 12/23/2022] Open
Abstract
INTRODUCTION traumatic brain injury (TBI) is very often associated with spasticity. Medical interventions may include medications such as baclofen, a Gamma-Aminobutyric Acid (GABA) -receptor agonist of poor lipid solubility. Intrathecal baclofen (ITB) administration is a contemporary treatment option which minimizes adverse effects in contrast with the oral form of the drug. Regarding low urinary tract dysfunction, TBI, as a suprapontine lesion, results in neurogenic detrusor overactivity. Frequency, urgency and urge incontinence are the predominant signs and symptoms of this condition. Our study aims to report the potential changes in bladder function in patients with spasticity, due to TBI, after the implantation of the baclofen pump and the control of spasticity. MATERIAL AND METHODS We report three cases of TBI whose spasticity responded well to ITB. We evaluated our medical reports regarding bladder function retrospectively, before and after baclofen pump implantation. We compared the data of bladder diaries and urodynamic parameters. RESULTS Bladder function was improved in all patients. Regarding bladder diaries; the number of incontinence and micturition episodes was decreased and the volume per void was slightly increased. Regarding urodynamic parameters; bladder capacity and reflex volume increased, Pdetmax decreased, PVR was the same and DLPP was slightly decreased. CONCLUSIONS Although the baclofen pump is implanted to treat spasticity, detrusor activity may be also affected. Therefore, patients' urologic profiles should also be reevaluated after ITB. Further prospective studies are required to investigate the effect of ITB on bladder function in the clinical field and also at the basic science level.

Neurogenic lower urinary tract dysfunction in association with severity of degenerative spinal diseases: Short-term outcomes of decompression surgery. Low Urin Tract Symptoms 2022; 14:346-357.

Abstract
OBJECTIVES Cervical myelopathy (CM) and lumbar canal stenosis (LCS) are common degenerative spinal diseases among the elderly, and the major associated complaints include lower urinary tract symptoms (LUTS). The aim of this study was to investigate subjective and objective urological parameters of patients undergoing decompression surgery for CM and LCS. METHODS We retrospectively reviewed patients who underwent evaluation by the International Prostate Symptom Score (IPSS) and uroflowmetry before decompression surgery for CM and LCS. Patients with comorbidities that can affect LUTS were excluded. Postoperative changes were evaluated in patients followed up within 1 month. RESULTS Among referrals to urological consultations for LUTS, 231 patients were evaluated preoperatively. Moderate-severe urinary symptoms (IPSS ≥ 8) were present in 59.8% of 92 CM patients and 64.0% of 139 LCS patients. Poor voiding patterns defined as maximum urinary flow rate <12 mL/s or postvoid residual volume >100 mL were identified in 26.1% of CM and 25.2% of LCS. While IPSS did not associate with disease severity, poor voiders presented with worse Japanese Orthopedic Association scores. Moreover, poor voiders suffered for a longer period of time from orthopedic symptoms due to LCS. In followed-up patients (CM, n = 32; LCS, n = 47), total IPSS, storage subscores, and voiding subscores were significantly improved after surgery, as was voiding time from uroflowmetry. CONCLUSIONS This study demonstrated high prevalence of lower urinary tract dysfunction of CM and LCS as well as short-term effectiveness of decompression surgery. These results would encourage urologists to consider an orthopedic consultation when lower urinary tract dysfunction is identified in patients with degenerative spinal diseases.

Abstract
A 14-year-old male neutered domestic short-hair cat was presented for a history of behavioral changes and episodes of urinary retention. Neurological examination was consistent with a multifocal intracranial neuroanatomical localization, with suspected right sided lateralisation and suspected raised intracranial pressure (ICP). Brain magnetic resonance imaging (MRI) revealed an intraventricular multilobulated well-defined T2W-hyperintense and T1W-isointense, markedly contrast enhancing mass lesion within the dorsal aspect of the III ventricle extending into the left lateral ventricle, causing hypertensive obstructive hydrocephalus. A ventriculoperitoneal shunt (VPS) was placed within the left lateral ventricle, followed by a radiation therapy (RT) course of 45 Gy total dose in 18 daily fractions. Six-months post-RT, computed tomography revealed mild reduction in mass size and resolution of the hydrocephalus. The patient was neurologically normal with no medical treatment. Raised ICP causes severe clinical signs, can lead to brain ischaemia and herniation, and significantly increases anesthetic risk during RT. Placement of a VPS in cats with hypertensive obstructive hydrocephalus may allow improvement of neurological signs due to raised ICP, and therefore making the patient a more stable candidate for anesthesia and radiation therapy.

Abstract
The innervation of the pelvic region is complex and includes extensive neurologic pathways. The higher centres' organisation determining the pelvic floor and organs' function remains a challenge understanding the physiological and pain mechanisms. Psychological and emotional factors have a profound influence on the pelvic floor and organ dysfunction such as LUTS. LUTS are associated with stress, depression, and anxiety. Neuroception is a subconscious neuronal system for detecting threats and safety and might explain the permanent disturbance of higher brain centres maintaining functional urological and gastrointestinal disorders and sphincter dysfunction.

Abstract
PURPOSE Neurogenic bladder dysfunction (NGB) has an impact on the quality of life, which made it an important research subject in preclinical studies. The present review investigates the effect of stem cell (SC) therapy on bladder functional recovery after the onset of spinal cord injury (SCI), multiple sclerosis (MS), Parkinson disease (PD), and stroke in rodent models. METHODS All experiments evaluated the regenerative potential of SC on the management of NGB in rodent models up to June 2019, were included. From 1,189 relevant publications, 20 studies met our inclusion criteria of which 15 were conducted on SCI, 2 on PD, 2 on stroke, and 1 on MS in the rodent models. We conducted a meta-analysis on SCI experiments and for other neurological diseases, detailed urodynamic findings were reported. RESULTS The common SC sources used for therapeutical purposes were neural progenitor cells, bone marrow mesenchymal SCs, human amniotic fluid SCs, and human umbilical cord blood SCs. There was a significant improvement of micturition pressure in both contusion and transaction SCI models 4 and 8 weeks post-SC transplantation. Residual urine volume, micturition volume, and bladder capacity were improved 28 days after SC transplantation only in the transaction model of SCI. Nonvoiding contraction recovered only in 56 days post-cell transplantation in the contusion model. CONCLUSION Partial bladder recovery has been evident after SC therapy in SCI models. Due to limitations in the number of studies in other neurological diseases, additional studies are necessary to confirm the detailed mechanism for bladder recovery.

Urodynamic and gait analyses in multiple system atrophy. J Neurol Sci 2020; 411:116676. [PMID: 32001376 DOI: 10.1016/j.jns.2020.116676] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2019] [Revised: 12/07/2019] [Accepted: 01/07/2020] [Indexed: 01/06/2023]
Abstract
BACKGROUND Limited attention has been paid to the relationship between bladder dysfunction and motor disorder in multiple system atrophy (MSA). OBJECTIVE We aimed to correlate pressure-flow urodynamic parameters with video-gait analysis parameters in MSA. METHODS We recruited 34 patients with MSA: 20 men, 14 women; age 64.0 + - 7.9 years; disease duration 2 years (1-4 years). Nineteen cases had the cerebellar form, and 15 had the parkinsonian form; the patients were taking levodopa 300 mg/day (100-400 mg). All patients underwent pressure-flow urodynamics (parameters: detrusor overactivity [noted in 72%] and Watts factor) and video-gait analysis (parameters: time and the number of strides taken to walk 5 m (simple task) and time for timed up and go (complex task). Statistical analysis was done using Student's t-test to analyze the relation between detrusor overactivity and gait, and Spearman's rank correlation coefficient test to analyze the relation between the remaining parameters and gait. RESULTS We found no relation between filling-phase urodynamics (detrusor overactivity) and video-gait analysis parameters. Also, we found no relation between voiding-phase urodynamics (Watts factor, reflecting detrusor power) and all three video-gait analysis parameters in our MSA patients. CONCLUSION The fact that neither detrusor overactivity nor the Watts factor was related with motor disorders in the present study suggests that bladder dysfunction occurs independently from motor disorder in MSA.

Abstract
Traumatic brain injuries (TBIs) are a serious public health issue worldwide with increased mortality as well as severe disabilities and injuries caused by falls and road accidents. Unfortunately, there is no approved therapy for TBIs, and bladder dysfunction is a striking symptom. Accordingly, we attempted to analyze bladder dysfunction and voiding efficiency in rats with a TBI at different time-course intervals. Time-dependent analyses were scheduled from the next day until four weeks after a TBI. Experimental animals were grouped and analyzed under the above conditions. Cystometric measurements were used for this analysis and were further elaborated as external urethral sphincter electromyographic (EUS-EMG) activity and cystometrogram (CMG) measurements. Moreover, magnetic resonance imaging (MRI) studies were conducted to investigate secondary injury progression in TBI rats, and results were compared to normal control (NC) rats. Results of EUS-EMG revealed that the burst period, active period, and silent period in TBI rats were drastically reduced compared to NC rats, but they increased later and reached a stagnant phase. Likewise, in CMG measurements, bladder function, the voided volume, and voiding efficiency decreased immediately after the TBI, and other parameters like the volume threshold, inter-contraction interval, and residual volume drastically increased. Later, those levels changed, and all observed results were compared to NC rats. MRI results revealed the prevalence of cerebral edema and the progression of secondary injury. All of the above-stated results of the experiments were extensively substantiated. Thus, these innovative findings of our study model will surely pave the way for new therapeutic interventions for TBI treatment and prominently highlight their applications in the field of neuroscience in the future.

Abstract
Lower urinary tract symptoms (LUTS) are exceptionally common and debilitating, and they are likely caused or exacerbated by dysfunction of neural circuits controlling bladder function. An incomplete understanding of neural control of bladder function limits our ability to clinically address LUTS. Barrington's nucleus (Bar) provides descending control of bladder and sphincter function, and its glutamatergic neurons expressing corticotropin releasing hormone (BarCrh/Vglut2) are implicated in bladder control. However, it remains unclear whether this subset of Bar neurons is necessary for voiding, and the broader circuitry providing input to this control center remains largely unknown. Here, we examine the contribution to micturition behavior of BarCrh/Vglut2 neurons relative to the overall BarVglut2 population. First, we identify robust, excitatory synaptic input to Bar. Glutamatergic axons from the periaqueductal gray (PAG) and lateral hypothalamic area (LHA) intensely innervate and are functionally connected to Bar, and optogenetic stimulation of these axon terminals reliably provokes voiding. Similarly, optogenetic stimulation of BarVglut2 neurons triggers voiding, whereas stimulating the BarCrh/Vglut2 subpopulation causes bladder contraction, typically without voiding. Next, we genetically ablate either BarVglut2 or BarCrh/Vglut2 neurons and found that only BarVglut2 ablation replicates the profound urinary retention produced by conventional lesions in this region. Fiber photometry recordings reveal that BarVglut2 neuron activity precedes increased bladder pressure, while activity of BarCrh/Vglut2 is phase delayed. Finally, deleting Crh from Bar neurons has no effect on voiding and related bladder physiology. Our results help identify the circuitry that modulates Bar neuron activity and identify subtypes that may serve different roles in micturition.

Abstract
A lesion of sacrococcygeal spinal nerve roots forming a structure that resembles a horse's tail results in the development of clinical entity identified as the cauda equina syndrome (CES). The disease can evolve slowly and symptomatology can be incomplete, but the fully developed CES is characterized by pain and altered sensation in the pelvic extremities, tail, perianogenital region, paresis or plegia of hind limbs, incontinence and impotence. Major causes of CES in dogs are degenerative changes of the lumbosacral vertebral column, haematoma, inflammation, neoplasm or trauma. The diagnosis is based on history, clinical presentation, neurological symptomatology, spinal röntgenography, computed tomography, and magnetic resonance imaging. In animals experiencing initial episodes of CES, conservative therapy can be attempted. But the only rational treatment of patients with severe neurological deficit is surgical decompression of the neural structures. The outcome depends on the underlying aetiology and the degree of sensory, motor and autonomic dysfunction. Canine and porcine experimental models mimicking the CES showed the involvement of intrinsic spinal cord structures. This points out the need for an early diagnosis followed by aggressive management before irreversible neuronal lesions develop. The search strategy involved the PubMed, Medline, Embase and ISI Web of Science from January 2000 to August 2017 using the terms 'cauda equina syndrome' and 'lumbosacral stenosis' in the English language literature; also references from selected papers were scanned and relevant articles included.

Abstract
There is a correlation between the severity of neurological impairment in patients that have suffered a cerebrovascular accident and the nerve growth factor (NGF) level. This study addressed the fabrication of a titanium nitride (TiN) and reduced graphene oxide (RGO)-based composite with remarkable electrocatalytic activity towards NGF oxidation in a phosphate buffer solution (PB, 0.1 M). The proposed electrochemical sensor was linearly related to the NGF concentration in the range of 10 nM-5 μM with a detection limit of 2.6 nM.

Abstract
Micturition is a complex process involving the bladder, spinal cord, and the brain. Highly sophisticated central neural program controls bladder function by utilizing multiple brain regions, including pons and suprapontine structures. Periaqueductal grey, insula, anterior cingulate cortex, and medial prefrontal cortex are components of suprapontine micturition centers. Under pathologic conditions such as epilepsy, urinary dysfunction is a frequent symptom and it seems to be associated with increased suprapontine cortical activity. Interestingly, micturition can also trigger seizures known as reflex epilepsy. During voiding behavior, frontotemporal cortical activation has been reported and it may induce reflex seizures. As current researches are only limited to present clinical cases, more rigorous investigations are needed to elucidate biological mechanisms of micturition to advance our knowledge on the process of micturition in physiology and pathology.

Abstract
Background Nowadays, magnetic resonance imaging (MRI) is the gold standard for evaluation and diagnosis of spinal cord abnormalities, which are considered among the leading causes of neurogenic bladder; however, MRI is a costly imaging method and is not available at all health centers. Sporadic studies have shown the alignment of MRI with ultrasonography results in diagnosis of spinal abnormalities; although none of these studies has expressed the diagnostic value of ultrasonography. Objective The aim of this study was to evaluate the diagnostic value of ultrasonography in detection of spinal abnormalities in children with neurogenic bladder. Methods This is a cross-sectional study carried out from January 2014 to November 2015 on patients with neurogenic bladder referred to Department of Radiology, Dr. Sheikh Hospital, Mashhad University of Medical Sciences, Mashhad, Iran. All patients underwent sonography of the spinal cord and soft-tissue masses; also, a spinal MRI scan was performed. The existence of spina bifida, sacral agenesis, posterior vertebral arch defects, mass, tethered cord, myelomeningocele, lipoma and fatty infiltration, dural ectasia, hydromyelia and syringomyelia, and diastomatomyelia was recorded during each imaging scan. Chi-square and Fisher’s tests were used for data analysis using SPSS 19.0 software, and the sensitivity and specificity of ultrasonography findings were calculated by MedCale 26 software. Results Forty patients with neurogenic bladder (22 males/18 females), with an average of 25.73±19.15 months, were enrolled. The most common abnormality was found in patients’ MRI was tethered cord syndrome (70%). There was a significant relationship between ultrasonographic and MRI findings in spina bifida abnormalities (p=0.016), sacral agenesis (p=0.00), tethered cord (p=0.00), myelomeningocele (p=0.00), and lipoma and fatty infiltration (p=0.01). Ultrasonography had a sensitivity of 20.0%–100% and a specificity of 85.7%–100% depending on the detected type of abnormality. Conclusion It seems that ultrasonography has an acceptable and desirable sensitivity and specificity in the diagnosis of most of the spinal cord abnormalities in children with a neurogenic bladder.

Abstract
Barrington's nucleus (Bar) is thought to contain neurons that trigger voiding and thereby function as the "pontine micturition center." Lacking detailed information on this region in mice, we examined gene and protein markers to characterize Bar and the neurons surrounding it. Like rats and cats, mice have an ovoid core of medium-sized Bar neurons located medial to the locus coeruleus (LC). Bar neurons express a GFP reporter for Vglut2, develop from a Math1/Atoh1 lineage, and exhibit immunoreactivity for NeuN. Many neurons in and around this core cluster express a reporter for corticotrophin-releasing hormone (BarCRH ). Axons from BarCRH neurons project to the lumbosacral spinal cord and ramify extensively in two regions: the dorsal gray commissural and intermediolateral nuclei. BarCRH neurons have unexpectedly long dendrites, which may receive synaptic input from the cerebral cortex and other brain regions beyond the core afferents identified previously. Finally, at least five populations of neurons surround Bar: rostral-dorsomedial cholinergic neurons in the laterodorsal tegmental nucleus; lateral noradrenergic neurons in the LC; medial GABAergic neurons in the pontine central gray; ventromedial, small GABAergic neurons that express FoxP2; and dorsolateral glutamatergic neurons that express FoxP2 in the pLC and form a wedge dividing Bar from the dorsal LC. We discuss the implications of this new information for interpreting existing data and future experiments targeting BarCRH neurons and their synaptic afferents to study micturition and other pelvic functions.

Abstract
Case series summary Four cats that presented with severe cluster seizures developed neurogenic urinary retention in the postictal phase. None of the cats had previous seizures. Micturition was reported as normal in all cats for 3 or more years before seizure onset. All cats required a continuous rate infusion of propofol to control the seizure activity. In all cats manual bladder expression was performed every 8 h until recovery of normal micturition. One cat was started on phenoxybenzamine to reduce internal urethral sphincter tone. All cats recovered normal micturition within 4 weeks of the last cluster of seizures. Relevance and novel information Transient neurogenic urinary retention has not previously been reported in cats or dogs following severe cluster seizures. Urinary retention should be considered a potential postictal deficit, requiring prompt recognition and treatment to avoid urinary tract infection and detrusor muscle atony.

Abstract
ABSTRACT
The prevalence of urinary tract infections (UTIs) in dogs with Type I intervertebral disc extrusion has been reported as high as 38% within 6 wk of surgery. Proper treatment of a UTI is important with myelopathy because it is a risk factor for persistent infection and reinfection in dogs. The study authors' investigated the incidence of UTIs in dogs having received either cefovecin or cefazolin as a preoperative prophylactic antibiotic for thoracolumbar hemilaminectomy. Thirty-nine dogs were retrospectively identified and assigned to groups based on preoperative antibiotic administration and postoperative urinary tract management. Urinalysis and urine culture performed preoperatively, at 2 wk, and at 6 wk, were reviewed to determine the incidence of UTIs. Urinary tract management, grade of neurologic deficit, time to ambulation, and time to voluntary urination were identified to evaluate for additional risk factors. No significant prevalence of UTI incidence was appreciated between the cefovecin and cefazolin groups. Patients with higher grades of neurologic deficit and that took longer to regain ambulation and voluntary urination were at significantly greater risk for UTIs throughout the postoperative period. This study reemphasizes the importance of continued surveillance for UTIs in patients with prolonged neurologic recovery.

Abstract
Benign prostatic hyperplasia (BPH), which causes lower urinary tract symptoms (LUTS), is a common diagnosis among the ageing male population with increasing prevalence. Many risks factors, both modifiable and non-modifiable, can increase the risk of development and progression of BPH and LUTS. The symptoms can be obstructive (resulting in urinary hesitancy, weak stream, straining or prolonged voiding) or irritative (resulting in increased urinary frequency and urgency, nocturia, urge incontinence and reduced voiding volumes), or can affect the patient after micturition (for example, postvoid dribble or incomplete emptying). BPH occurs when both stromal and epithelial cells of the prostate in the transitional zone proliferate by processes that are thought to be influenced by inflammation and sex hormones, causing prostate enlargement. Patients with LUTS undergo several key diagnostic investigations before being diagnosed with BPH. Treatment options for men with BPH start at watchful waiting and progress through medical to surgical interventions. For the majority of patients, the starting point on the treatment pathway will be dictated by their symptoms and degree of bother.

Abstract
Spinal cord injury (SCI) leads generally to an irreversible loss of sensory functions and voluntary motor control below injury level. Cures that could repair SCI and/or restore voluntary walking have not been yet developed nor commercialized. Beyond the well-known loss of walking capabilities, most SCI patients experience also a plethora of motor problems and health concerns including specific bladder and bowel dysfunctions. Indeed, chronic constipation and urinary retention, two significant life-threatening complications, are typically found in patients suffering of traumatic (e.g., falls or car accidents) or non-traumatic SCI (e.g., multiple sclerosis, spinal tumors). Secondary health concerns associated with these dysfunctions include hemorrhoids, abdominal distention, altered visceral sensitivity, hydronephrosis, kidney failure, urinary tract infections, sepsis and, in some cases, cardiac arrest. Consequently, individuals with chronic SCI are forced to regularly seek emergency and critical care treatments when some of these conditions occur or become intolerable. Increasing evidence supports the existence of a novel experimental approach that may be capable of preventing the occurrence or severity of bladder and bowel problems. Indeed, recent findings in animal models of SCI have revealed that, despite paraplegia or tetraplegia, it remains possible to elicit episodes of micturition and defecation by acting pharmacologically or electrically upon specialized lumbosacral neuronal networks, namely the spinal or sacral micturition center (SMC) and lumbosacral defecation center (LDC). Daily activation of SMC and LDC neurons could potentially become, new classes of minimally invasive treatments (i.e., if orally active) against these dysfunctions and their many life-threatening complications.

Abstract
OBJECTIVES To assess the prevalence of gynaecological pathologies in women with Fowler's syndrome (FS) which is characterised by chronic urinary retention (CUR) secondary to failure of urethral sphincter to relax and allow normal voiding. STUDY DESIGN This was a case control study conducted at a tertiary referral centre specialised in managing women with FS. There were 41 patients with FS in the study group with CUR without mechanical obstruction of the urethra or neurological problem. All patients had raised maximum urethral closure pressure on urethral pressure profile, high urethral sphincter volume on ultrasound and complex repetitive discharges on eletromyography of the urethral sphincter. Normal voiding was established in these women after treatment with sacral neuromodulation. Fifty women without voiding dysfunction acted as control group. Data was obtained by using standard questionnaire for both the groups. Information was collected regarding gynaecological pathologies such as endometriosis, polycystic ovarian syndrome, menstrual abnormalities, ovarian cysts and subfertility and also regarding previous pregnancies. Analysis was performed using SPSS software from IBM Corporation. RESULTS At least one gynaecological pathology was present in 33 (80%) patients with FS compared to 16 (32%) women from control group (P<0.001). This included a higher incidence of endometriosis (29% versus 6%, P=0.003), PCOS (24% versus 8%, P=0.041) and subfertility (34% versus 8%, P=0.003). The incidence of menstrual abnormalities and ovarian cysts was similar in both groups (P>0.05). CONCLUSION Subfertility was more prevalent in women with FS in our study. Though the prevalence of different pathologies was higher in the FS group compared to the control group, it remained similar to that found in the normal female population in the published literature. Thus, it is not possible to state whether FS is caused by a hormonally based disorder. It took patients many years before they could get right diagnosis and treatment for FS. Early investigation of chronic urinary retention and referral to specialists for appropriate treatment in this small group of women can result in better health and improvement in their quality of life.

Abstract
Recent advances in microelectronics and wireless transmission technology have led to the development of various implantable sensors for real-time monitoring of bladder conditions. Although various sensing approaches for monitoring bladder conditions were reported, most such sensors have remained at the laboratory stage due to the existence of vital drawbacks. In the present study, we explored a new concept for monitoring the bladder capacity on the basis of potentiometric principles. A prototype of a potentiometer module was designed and fabricated and integrated with a commercial wireless transmission module and power unit. A series of in vitro pig bladder experiments was conducted to determine the best design parameters for implementing the prototype potentiometric device and to prove its feasibility. We successfully implemented the potentiometric module in a pig bladder model in vitro, and the error of the accuracy of bladder volume detection was <±3%. Although the proposed potentiometric device was built using a commercial wireless module, the design principles and animal experience gathered from this research can serve as a basis for developing new implantable bladder sensors in the future.

Abstract
The prevalence of lower urinary tract (LUT) dysfunction in peripheral nervous system (PNS) disorders is larger than in comparable control populations. This is particularly true for polyneuropathies with autonomic nervous system involvement, and for localized lesions with LUT innervation. LUT symptoms may be the guide to the diagnosis of processes localized in the lumbosacral spinal canal (as in cauda equina syndrome), and in the pelvis. Typical LUT dysfunctions (LUTD) caused by PNS involvement include bladder and sphincter hypoactivity with poor emptying, and incontinence. Paradoxically, bladder overactivity may also occur in pure PNS lesions. The acute cauda equina syndrome is an emergency requiring magnetic resonance imaging and surgery; in chronic neurogenic LUTD due to PNS involvement, the diagnosis of the lesion may be clarified by clinical neurophysiologic testing. Other important causes of neurogenic LUT dysfunction are perineoabdominal and pelvic surgeries. Surgeons are devising nerve-sparing techniques to prevent such major and often persistent complications in patients who are otherwise cured of the underlying disease. LUTD significantly affects the quality of life in patients and may lead to recurring urinary infections and upper urinary tract involvement. Thorough assessment of LUT function by urodynamics may be necessary in patients who are not improved by simple conservative measures.

Abstract
Postural tachycardia syndrome (PoTS), a form of dysautonomia, is characterized by orthostatic intolerance, and is frequently accompanied by a range of symptoms including palpitations, lightheadedness, clouding of thought, blurred vision, fatigue, anxiety, and depression. Although the estimated prevalence of PoTS is approximately 5–10 times as common as the better-known condition orthostatic hypotension, the neural substrates of the syndrome are poorly characterized. In the present study, we used magnetic resonance imaging (MRI) with voxel-based morphometry (VBM) applying the diffeomorphic anatomical registration through exponentiated lie algebra (DARTEL) procedure to examine variation in regional brain structure associated with PoTS. We recruited 11 patients with established PoTS and 23 age-matched normal controls. Group comparison of gray matter volume revealed diminished gray matter volume within the left anterior insula, right middle frontal gyrus and right cingulate gyrus in the PoTS group. We also observed lower white matter volume beneath the precentral gyrus and paracentral lobule, right pre- and post-central gyrus, paracentral lobule and superior frontal gyrus in PoTS patients. Subsequent ROI analyses revealed significant negative correlations between left insula volume and trait anxiety and depression scores. Together, these findings of structural differences, particularly within insular and cingulate components of the salience network, suggest a link between dysregulated physiological reactions arising from compromised central autonomic control (and interoceptive representation) and increased vulnerability to psychiatric symptoms in PoTS patients.

Abstract
Clean intermittent self-catheterisation is carried out when the bladder cannot be emptied adequately by voiding. Because learning how to self-catheterise can be daunting, it is essential that the nurse has the time, knowledge and skills necessary support the patient during the learning phase, so that he or she can develop confidence and master the technique. Causes for urinary retention are considered and step-by-step instructions are given for both female and male patients, including problems that may be encountered and how these can be overcome. Examples of catheters and other aids available are suggested, with reference to particular features they may have, to overcome difficulties or to assist patients with particular needs. Issues including infection, frequency of catheterisation and fluid intake are also discussed.

Abstract
Detrusor underactivity (DUA) is a poorly understood, yet common, bladder dysfunction, referred to as underactive bladder, which is observed in both men and women undergoing urodynamic studies. Despite its prevalence, no effective therapeutic approaches exist for DUA. Exactly how the contractile function of the detrusor muscle changes with ageing is unclear. Data from physiological studies in animal and human bladders are contradictory, as are the results of the limited number of clinical studies assessing changes in urodynamic parameters with ageing. The prevalence of DUA in different patient groups suggests that multiple aetiologies are involved in DUA pathogenesis. Traditional concepts focused on either efferent innervation or myogenic dysfunction. By contrast, contemporary views emphasize the importance of the neural control mechanisms, particularly the afferent system, which can fail to potentiate detrusor contraction, leading to premature termination of the voiding reflex. In conclusion, the contemporary understanding of the aetiology and pathophysiology of DUA is limited. Further elucidation of the underlying mechanisms is needed to enable the development of new and effective treatment approaches.

Abstract
The 2 major functions of the lower urinary tract are the storage and emptying of urine. These processes are controlled by complex neurophysiologic mechanisms and are subject to injury and disease. When there is disruption of the neurologic control centers, dysfunction of the lower urinary tract may occur. This is sometimes referred to as the "neurogenic bladder." The manifestation of dysfunction depends on the level of injury and severity of disruption. Patients with lesions above the spinal cord often have detrusor overactivity with no disruption in detrusor-sphincter coordination. Patients with well-defined suprasacral spinal cord injuries usually present with intact reflex detrusor activity but have detrusor sphincter dyssynergia, whereas injuries to or below the sacral spinal cord usually lead to persistent detrusor areflexia. A complete gynecologic, urologic, and neurologic examination should be performed when evaluating patients with neurologic lower urinary tract dysfunction. In addition, urodynamic studies and neurophysiologic testing can be used in certain circumstances to help establish diagnosis or to achieve better understanding of a patient's vesicourethral functioning. In the management of neurogenic lower urinary tract dysfunction, the primary goal is improvement of a patient's quality of life. Second to this is the prevention of chronic damage to the bladder and kidneys, which can lead to worsening impairment and symptoms. Treatment is often multifactorial, including behavioral modifications, bladder training programs, and pharmacotherapy. Surgical procedures are often a last resort option for management. An understanding of the basic neurophysiologic mechanisms of the lower urinary tract can guide providers in their evaluation and treatment of patients who present with lower urinary tract disorders. As neurologic diseases progress, voiding function often changes or worsens, necessitating a good understanding of the underlying physiology in question.

Abstract
STUDY DESIGN Immunohistochemical and behavioral study using a rat model of acute cauda equina syndrome (CES). OBJECTIVE To determine the effect of duration of extradural cauda equina compression (CEC) on bladder, sensory, and motor functions. SUMMARY OF BACKGROUND DATA Cauda equina syndrome is a devastating injury treated with surgical decompression. Controversy exists regarding the optimal timing of surgery. Animal models of CES have focused on motor recovery but have not evaluated pain behavior or bladder function. METHODS A 4-mm balloon-tipped Fogarty catheter was inserted between the fifth and sixth lumbar lamina into the dorsal epidural space and inflated to compress the nerve roots at the L5 level. Maximal inflation was maintained at a constant balloon pressure of 304 Kpa for 1 or 4 hours. The catheter was inserted but not inflated in sham animals. During a 4-week period, pain behavior, bladder function, and locomotor function were assessed. Postmortem bladders and the lesion site were collected for analysis. RESULTS Mechanical allodynia was 2-fold greater in 1-hour CEC rats than 4-hour CEC (P=0.002) and sham-operated (P=0.001) rats at 4 weeks after injury. Hind limb locomotor function was not different between groups at 4 weeks after injury. Both the 1-hour and 4-hour CEC group rats retained greater volumes of urine than the sham-operated rats throughout the 4-week period (P<0.05). At 4 weeks, bladder weight and volume were 2-fold greater in the 4-hour CEC group than in the 1-hour CEC group (P=0.006 and P=0.01, respectively). Histology of the bladder wall revealed an overall thinning after 4-hour CEC. Histology of the lesion site revealed a greater overall severity of injury after 4-hour CEC than after 1-hour CEC (P=0.04) and sham operation (P=0.002). CONCLUSION Our data suggest that recovery of motor function is less affected by the timing of decompression compared with bladder function and pain behavior. Early decompression preserved bladder function but was associated with allodynia. LEVEL OF EVIDENCE N/A.

Abstract
Clean intermittent self-catheterisation (CISC) is a treatment option for people with urinary incontinence-particularly those with neurogenic bladder dysfunction. When used for appropriate patients it has been shown to promote continence, maintain safe bladder function and improve quality of life. There is a range of different products available on prescription for patients, and community nurses are ideally placed to advise them regarding products and to offer choice to those performing CISC. CISC can promote privacy and dignity for patients with urinary incontinence due to impaired bladder emptying, and community nurses should offer this intervention to patients for whom it is suitable and support them in learning the technique.

Abstract
STUDY DESIGN Retrospective cross-sectional study. OBJECTIVE To delineate the neurogenic bladder type in patients with cauda equina syndrome (CES) and to suggest, in light of the clinical, radiological, and electrophysiological findings, a possible cause of bladder dysfunction. SUMMARY OF BACKGROUND DATA Many patients with CES experience bladder dysfunction, although the type of neurogenic bladder is quite variable in the clinical setting. Bladder dysfunction in patients with CES is usually areflexic or acontractile detrusor. However, detrusor overactivity (DOA) also reported the cases that cannot be explained by pure root injuries in the cauda equina region. METHODS Patients with CES with neurogenic bladder were studied, all of whom (n = 61; mean age ± SD, 48.0 ± 15.9 yr) underwent urodynamic analysis, magnetic resonance imaging (MRI), and electrophysiology. According to the urodynamic findings, the neurogenic bladder was classified into 2 types: DOA and detrusor underactivity or acontractility. The highest level of injury (HLI) or level of injury was determined and analyzed on the basis of the clinical-urodynamic and electrophysiological findings, respectively. RESULTS Twenty patients with CES (32.8%) showed DOA; in most of them (85.0%, 17/20 patients), the HLI on electrophysiological assessment was L2 or above. Forty-one patients with CES showed detrusor underactivity or acontractility; and most of the patients with CES whose HLI was L3 or below showed detrusor underactivity or acontractility (91.2%, 31/34 patients). None of the HLI or level of injury from the clinical or magnetic resonance imaging findings correlated with neurogenic bladder type. We also found that urodynamic findings including maximal detrusor pressure and bladder capacity was partially correlated with the HLI on electrophysiological assessment (r² = 0.244, P < 0.001 and r² = 0.330; P < 0.001, respectively). CONCLUSION DOA was seen most often in patients with CES whose HLI was L2 or above, and might be associated with combined conus medullaris lesion. Electrophysiology might be the most useful assessment tool for prediction of neurogenic bladder type in patients with CES.

Abstract
Urinary bladder dysfunction presents a major problem in the clinical management of patients suffering from pathological conditions and neurological injuries or disorders. Currently, the etiology underlying altered visceral sensations from the urinary bladder that accompany the chronic pain syndrome, bladder pain syndrome (BPS)/interstitial cystitis (IC), is not known. Bladder irritation and inflammation are histopathological features that may underlie BPS/IC that can change the properties of lower urinary tract sensory pathways (e.g., peripheral and central sensitization, neurochemical plasticity) and contribute to exaggerated responses of peripheral bladder sensory pathways. Among the potential mediators of peripheral nociceptor sensitization and urinary bladder dysfunction are neuroactive compounds (e.g., purinergic and neuropeptide and receptor pathways), sensory transducers (e.g., transient receptor potential channels) and target-derived growth factors (e.g., nerve growth factor). We review studies related to the organization of the afferent limb of the micturition reflex and discuss neuroplasticity in an animal model of urinary bladder inflammation to increase the understanding of functional bladder disorders and to identify potential novel targets for development of therapeutic interventions. Given the heterogeneity of BPS/IC and the lack of consistent treatment benefits, it is unlikely that a single treatment directed at a single target in micturition reflex pathways will have a mass benefit. Thus, the identification of multiple targets is a prudent approach, and use of cocktail treatments directed at multiple targets should be considered.

Abstract
AIMS The aim of this study was to assess experimental traumatic brain injury (TBI)-induced lower urinary tract dysfunction (LUTD) by monitoring systemic and urodynamic parameters using an implantable telemetry system. METHODS A single lateral fluid percussion TBI (FP-TBI; 3.4 atm) was administered to 10 female rats. Pressure micro-catheters were implanted in the abdominal aorta and bladder dome for simultaneous data recording. Hemodynamic and urodynamic variables recorded 24 hr before and 24 hr after injury were analyzed and compared. RESULTS TBI in the acute phase resulted in LUTD affecting bladder emptying, characterized by failure of voiding reflex, high capacity bladder, increased voided volume, prolonged intermicturition intervals, and loss of compliance. The dominant symptom was urinary retention (100%) and incontinence (60%). The effects followed a pattern of initial loss of bladder function followed by either altered recovery of reflex micturition or a period of incontinence. With a moderate injury symptoms were temporary in 90% of animals and permanent in 10% of animals. Injury produced only transient hypertension (≤1 hr) with a maximum systolic pressure of 172.64 ± 14.53 mmHg (70% of animals). CONCLUSIONS The results demonstrate that experimental FP-TBI causes temporary bladder dysfunction that in more severe cases becomes permanent. Telemetry recordings revealed a sequence of events following injury that establishes moderate TBI as a risk factor for neurogenic bladder disorder. Results also suggest a correlation between lateral FP-TBI and incontinence.

Abstract
Lesions of the medial frontal micturition center can result in the activation of the pontine and spinal micturition centers when the bladder is full, causing urinary incontinence. Recognition of acute bladder incontinence as part of a cortical hemispheric stroke syndrome may reduce the likelihood of false localization to the spinal cord in patients with acute ischemic stroke eligible for acute reperfusion therapy. We describe a case of urinary incontinence due to anterior cerebral artery infarction and discuss the cortical localization of voluntary bladder control to the anterior cingulate gyrus, inferior frontal gyrus, middle frontal gyrus, and superior frontal gyrus.

Abstract
Antimuscarinic drugs are the first line pharmacotherapy for overactive bladder, but they are not always effective to achieve complete continence. Nevertheless in some patients urodynamic investigations reveal insufficient effects with continuing incontinence events even with dose optimization. The aim of this study is to evaluate the effect of association of Oxybutynin chloride, Trospium chloride and Solifenacin succinate administered orally for a minimum of 12 weeks in subjects with suprasacral spinal cord injury with urge-incontinence, urodynamicproven neurogenic detrusor overactivity dysfunction and detrusor-external sphincter dyssynergia to improve level of continence, reduce the risks of urologic complications and enhance QOL. This study was a randomized, double blind, controlled, balanced-parallel-groups investigation of orally administed Oxybutynin in addition to Trospium chloride in the first group and Oxybutynin in addition to Solifenacin in the other group. A total of 12 patients with neurogenic detrusor overactivity and clean intermittent catheterization were allocated into two treatment groups: 5 mg tablet of Oxibutinin and 20 mg tablet of Trospium Chloride were administered respectively 3 times a day and 4 times a day in the first group (Group A). 5 mg tablet of Oxibutinin and 10 mg tablet of Solifenacin were administered respective 3 times a day and once daily in the second group (Group B). In both group of patients we found a significant decrease in incontinence episodes, with an improvement of bladder compliance, bladder capacity and volume voided. Side effects were higher in patients of group B, but in generally well tolerated. In conclusion, a combined antimuscarinic treatment might be a right option for patients affected by neurogenic bladder refractory to previous antimuscarinic monotherapy, and might slow down or delay other more invasive treatments.

Abstract
Objective: To observe the urodynamic profile of the patients following non-traumatic myelopathies (NTMs) with neurogenic bladder. Setting: Neurological rehabilitation department of university tertiary research hospital. Materials and Methods: Seventy-nine patients (44 men) with monophasic NTM, with the age range 8-65 years (31.0 ± 16.0 years), were admitted for inpatients’ rehabilitation. Length of stay in rehabilitation ranged from 6 to 120 days (32.0 ± 24.8 days). Fifty-six patients (70.9%) had spinal lesion above D10, 17 had lesion between D10 and L2 (21.5%), and 6 (7.6%) had cauda equina syndrome. All patients had neurogenic bladder with urinary complaints. Urodynamic study (UDS) was performed in all patients. Results: UDS showed 71.4% patients (40/56) had neurogenic detrusor overactivity (NDO) with or without sphincter dyssynergy (DSD) with lesion above D10; only 52.9% patients (9/17) had NDO with or without DSD detrusor with lesion between D10 and L2; and majority (5/6 patients) had underactive detrusor in the cauda equina group. Bladder management was based on the UDS findings. No significant correlation was found (P > 0.05) between detrusor behavior and the level, severity (ASIA Impairment Scale) of spinal injury, or gender using chi-square test. Conclusions: Neurogenic bladder following NTM was observed in all patients. UDS suggested predominantly NDO in lesions above D10 and mixed pattern in between D10 and L2 lesions. No significant correlation was found between detrusor behavior and the level or severity of NTM in the study.
