Lower urinary tract disorders are significant prognostic indicators of institutionalisation and lower quality of life in the elderly and their incidence increases with age. Urodynamics, the gold standard in diagnosis, replicates symptoms to assess functionality through controlled filling and voiding of the bladder but its interpretation is subjective and may be inconclusive; often requiring further testing or leading to inappropriate treatment. Normal filling and voiding biomechanics of the bladder relate directly to the structural composition of the bladder wall. Alterations to tissue composition in aging and pathology have significant impacts on biomechanics but are yet to be fully described. The aim of this thesis was to gain insight into the individual microstructural components of the bladder wall and how they relate to the gross mechanical response. Additionally, representation of these observations in a mathematical model that can be used to improve our understanding of urodynamic data. This aim was achieved through a combination of in situ mechanical testing and the development of a microstructural constitutive model, which was then included within an overall micturition framework to simulate filling and voiding functions, and evaluated with clinical data. Coupled systems of multiphoton microscopy and uniaxial, biaxial and inflation testing were used to correlate extra cellular matrix interactions with the mechanical response of young and aged murine bladder. Wall-layer specific collagen fibre orientation, dispersion and recruitment were quantified and implemented into a novel microstructural constitutive model. The bladder was modelled as a nonlinear elastic, constrainedmixture planar membrane with contribution from smooth muscle and collagen fibres in the detrusor. Collagen recruitment in the detrusor was observed to occur at a finite stretch; correlated with a steep increase in stiffness of the tissue, while collagen of the lamina propria plays a capacitance role. Collagen recruitment was modelled using a triangular probability density function; quantified from sequential microscopy images and fitted to mechanical data. Increased collagen area fraction and changes in dominant fibre orientation were attributed to reduced compliance in aged bladder. This behaviour was captured by the model. The microstructural model was modified to an isotropic thin-walled spherical membrane for the filling phase of a micturition model framework, consisting of a bladder outlet relation and urethral resistance relation. A contractile smooth muscle element was included in the active response. In the first steps towards clinical application the model was applied to male and female 'normal' patient urodynamic data to observe quality of model fit and estimate baseline parameter values. The model simulated key filling and voiding features seen in normal male and female clinical data. Mechanobiological modelling combined with clinically relevant micturition modelling has the potential to quantify bladder dysfunction. Moreover, improved understanding of how the microstructure influences macroscopic mechanics will yield improved understanding of how changes to the bladder impair its functionality. We predict that modelling will become a clinically relevant tool in urodynamics; leading to new options for diagnosis and management of patients with bladder dysfunction.

Bakgrund   Icke-maligna prostataförändringar är ett utbrett samhällsproblem och en vanlig anledning till att människor söker sjukvård. Prostatit och benign prostatahyperplasi är två icke-maligna förändringar som kan te sig på olika sätt och kan orsaka lidande hos de drabbade, ofta genom ”lower urinary tract symptoms” och smärta som är vanliga symtom. Att lindra lidande är vårdens uppgift och en sjuksköterskas ansvar.     Syfte Syftet med denna litteraturöversikt var att belysa hur det är att leva med en icke-malign prostataförändring.    Metod  Metoden som användes var icke-systematisk litteraturöversikt där 18 artiklar analyserades.    Resultat Resultatet efter att ha analyserat de inkluderad studierna visade att icke-maligna prostataförändringar kan ha inverkan på samliv och relationer, ge upphov till känslor av skam, rädsla och oro, att det finns faktorer som kan vara mer eller mindre gynnsamma vid dessa tillstånd samt att det finns rum för förbättring vid mötet med sjukvården.   Slutsats Resultatet i denna litteraturöversikt visar på att leva med icke-maligna prostataförändringar och symtomen de ger upphov till kan ha en tydlig inverkan på drabbade personers liv och livskvalitet i ett flertal aspekter / Background Non-malignant prostatic conditions are a prevalent problem in society and a common reason as to why people seek medical care. Prostatitis and benign prostatic hyperplasia are two examples of non-malignant conditions that can appear in different ways and that could cause the afflicted person suffering, oftentimes through symptoms like pain and lower urinary tract symptoms. Alleviating suffering is an undertaking of health-care professionals’ and a nurse’s responsibility.     Aim The aim of this literature review was to illuminate what it is like to live with a non-malignant prostatic condition.    Method Non-systematic literature review where 18 articles were analyzed.     Results The results of the included and analyzed studies show that non-malignant prostatic conditions can influence intimate relationships, cause feelings of shame, fear and worry, that there are factors that can be more or less favourable in relation to these conditions and that there is room for improvement in the meeting with healthcare professionals.    Conclusions The results in this non-systematic literature review show that living with non-malignant prostatic conditions, and the symptoms they cause, can have a significant influence on the affected persons’ lives and quality of life in several aspects.

Thesis advisor: Katherine Hutchinson / Lower urinary tract (LUTS) storage symptoms, including overactive bladder (OAB) and urinary incontinence (UI), are common conditions among women with significant health and economic consequences. Much of the existing literature on LUTS focuses on older, often postmenopausal women, and there is limited research available about prevalence, incidence and severity of LUTS in young women. For many young women in the United States, the period from the late teens through early twenties coincides with the period of emerging adulthood and college enrollment. The unique factors influencing women at this stage of development may be influential in understanding prevalence and correlates of OAB and UI later in the life-course. The purpose of this cross-sectional descriptive survey-based study was to explore and describe the experience of urinary storage symptoms, specifically OAB and UI, among female undergraduate college students, and to identify associated factors. Qualtrics online platform was used to create and distribute the survey to a sample of 1,800 female college undergraduate students at a private Catholic university in the northeast. Two instruments previously used to assess LUTS, the ICIQ-FLUTS and LUTS Tool, were combined into the Urinary Symptoms Scale with a one-week recall. Twelve items assessed LUTS storage symptoms of OAB and UI. The final sample consisted of 456 female undergraduate college students with a mean age of 20.3-years-old. The sample was predominantly White non-Hispanic. Most commonly reported symptoms included urgency (47.6%), frequency (52.6%), urinary incontinence (21.3%), stress urinary incontinence (28.8%), and urge urinary incontinence (16.4%). Total severity scores were low and highly skewed towards the lower range (M = 3.31; SD = 3.91). Participants with symptoms, most commonly reported experiencing symptoms rarely or sometimes during the past week. Perceived bother from urinary symptoms mean scores were low (M = 1.77) but extended the full range on a 0 to 10 scale. In this study, perceived bother from urinary symptoms as well as perceived impact of urinary symptoms on activities of daily life (ADLs) were significantly associated with care-seeking and use of self-management strategies. Interestingly, LUTS storage symptom severity was not significantly associated with care-seeking, but it was related to use of self-management strategies in this population. Perception of overall health, history of constipation/IBS, sexual activity, delayed toileting behaviors, and premature toileting behaviors were significant in multivariate analyses when controlling for other factors. Further research on the relationship of these factors and LUTS storage symptoms is needed. This study represented a first step in understanding college women’s experiences with LUTS storage symptoms and identifying the unique personal, behavioral and environmental factors associated with LUTS. The study found that OAB and UI symptoms are common among female college undergraduates. In addition, a number of personal and behavioral factors were found to be associated with LUTS storage symptoms. Given that many health-related behaviors established during college years may persist later in adulthood, identifying experiences and influences of young women’s LUTS storage symptoms is important in informing future research and practice recommendations. / Thesis (PhD) — Boston College, 2018. / Submitted to: Boston College.

O estudo pressão-fluxo pode contribuir muito para a quantificação dos STUI, porém é invasivo, demorado e de custo elevado. Métodos alternativos têm sido desenvolvidos procurando minimizar o procedimento invasivo necessário para medição da pressão vesical. Um método alternativo foi desenvolvido no Centro de Engenharia Biomédica da UNICAMP e consiste num dispositivo denominado conector uretral (Pat. N. PI 0502171-5). Trata-se de um dispositivo cilíndrico e vazado, que permite o escoamento de urina por seu interior. O paciente é orientado a introduzir o conector na uretra antes de iniciar a micção e, ao urinar, solicitado a ocluir a saída do dispositivo, interrompendo o fluxo urinário por um curto intervalo e permitindo o registro da pressão dentro da bexiga urinária. Neste trabalho, uma instrumentação e uma nova versão do conector uretral foram desenvolvidas para medir a pressão vesical em homens. Aplicado em testes clínicos em indivíduos com sintomas de obstrução infravesical decorrente de hiperplasia benigna da próstata, o conjunto demonstrou capacidade de diferenciar indivíduos com obstrução de indivíduos não obstruídos sem diferença significativa do que se obtém no estudo pressão-fluxo (p > 0,05). O conector apresentou sensibilidade e especificidade de 66,7%, valores similares aos dos métodos alternativos descritos na literatura. Além disso, 88,5% dos indivíduos relataram preferir o conector uretral ao estudo pressão-fluxo, indicando a importância do conector como método alternativo minimamente invasivo ao estudo urodinâmico convencional / Abstract: Urodynamic assessment has an important role in the decision of patients complaining of lower urinary tract symptoms (LUTS) to undergo prostate surgery. Pressure-flow study may contribute to the evaluation of LUTS, but its procedure is invasive, time-consuming and expensive. Alternative methods have been developed aiming at measuring vesical pressure in a less invasive manner. An alternative method was developed in the Center for Biomedical Engineering at UNICAMP and consists of a device named urethral connector (Pat. N. PI 0502171-5). The device has a cylindrical shape and an internal longitudinal hole that permits urine to pass through it. The patient is instructed to insert the urethral connector into his urethra before starting to urinate. During micturition, he is instructed to occlude the urine outlet of the device for a short period of time so that vesical pressure may be measured. In this work, an instrumentation and a new version of the urethral connector were developed to measure vesical pressure in men. The device and instrumentation were applied in clinical tests in individuals reporting LUTS secondary to infravesical obstruction due to benign prostatic hyperplasia. It was shown that this new method is capable of differentiating obstructed individuals from nonobstructed ones. Results were not significantly different from those obtained when conventional pressure-flow study was applied (p > 0.05). The urethral connector had a sensibility and specificity of 66.7%, values similar to those found by the alternative methods described in the literature. About 88.5% of the individuals evaluated reported to prefer the new method instead of the conventional assessment which reinforces the importance of the urethral connector as a less invasive and alternative method to the conventional urodynamic study / Mestrado / Engenharia Biomedica / Mestre em Engenharia Elétrica

Obstruções uretrais em felinos geralmente são secundárias à doença do trato urinário inferior felino (DTUIF), afecção comum em gatos. A doença pode ser auto-limitante, mas a obstrução uretral leva à parada da função renal, gerando uma série de distúrbios no organismo, que necessitam tratamento imediato. A maioria dos estudos sobre as alterações decorrentes da obstrução foi feito em animais em estado crítico ou experimentalmente. O objetivo do presente estudo foi descrever as principais alterações observadas em gatos obstruídos atendidos na rotina clínica e correlacioná-las. Foram avaliados 32 gatos machos com obstrução uretral e sem tratamento prévio. A avaliação constou de exame clínico, hemograma, bioquímica sérica (uréia, creatinina, proteína total, ALT, AST, fosfatase alcalina, sódio, potássio, cálcio, fósforo, magnésio, glicemia e lactato), gasometria venosa, exame e cultura de urina e eletrocardiograma (ECG). Os animais foram agrupados conforme o tempo de obstrução (mais e menos de 36 horas). As alterações mais comuns no histórico foram disúria (100% dos animais), disorexia (84,4%), apatia (71,8%), vocalização (68,7%) e oligodipsia (68,7%); no exame físico, desidratação (71,8%), taquipnéia (53,1%) e hipotermia (53,1%). As alterações laboratoriais mais freqüentes foram hipermagnesemia (100%), acidose metabólica (89,6%), hiperglicemia (88,9%), hiperazotemia (84,4%) e hiperpotassemia (80,6%). Vinte por cento dos gatos tinham infecção urinária. Alterações no ECG foram evidenciadas em 39,3% dos casos, sendo a parada atrial com ritmo sinoventricular a mais freqüente. Não houve relação entre as alterações no ECG e os níveis de potássio sérico. A análise dos grupos sugere agravamento da hiperazotemia, hiperpotassemia, hipermagnesemia e do estado geral com a evolução do processo. Nas correlações, a temperatura e a freqüência cardíaca apresentaram relação direta com pH sanguíneo, excesso de base e bicarbonato, e relação inversa com uréia, creatinina, potássio e fósforo. A uréia e creatinina se correlacionaram inversamente com sódio, pH sanguíneo, excesso de base e bicarbonato, e diretamente com potássio e fósforo. O estado geral correlacionou-se com a temperatura, uréia, creatinina, potássio, pH sanguíneo, excesso de base e bicarbonato. / Urethral obstruction is a frequent complication in cats with feline lower urinary tract disease (FLUTD), considered a common disease in cats. Most cases are self-limiting, but the urethral obstruction causes renal failure and metabolic alterations which needs immediate treatment. Previous reports selected cats that were critically ill or had a experimental induction of the disease. The goal of this study was to describe the clinical signs, laboratory and electrocardiographyc abnormalities in cats with urethral obstruction and to correlate these results. Thirty-two male cats with natural urethral obstruction and without previous therapy were studied. Complete blood count, serum chemistry profile (urea, creatinine, plasma protein, alanine transferase, aspartate transferase, alkaline phosphatase, sodium, potassium, calcium, phosphorus, magnesium, glucose and lactate), venous blood gas, urinalysis, urine culture and electrocardiogram (ECG) were performed. Two groups of 16 cats were composed (animals under and over 36 hours of obstruction). The most frequent abnormalities described were dysuria (100%), anorexia (84,4%), lethargy (71,8%), vocalization (68,7%), hypodipsia (68,7%), and dehydration (71,8%), tachypnea (53,1%) and hypothermia (53,1%) in physical evaluation. The laboratorial abnormalities most frequently observed were hypermagnesemia (100%), metabolic acidosis (89,6%), hyperglicemia (88,9%), azotemia (84,4%) and hyperkalemia (80,6%). Twenty per cent of cats had urinary infections. Abnormalities in ECG, such as atrial standstill with sinoventricular rhythm, were seen in 39,3% of cases, and there were no correlation with hyperkalemia. The analyses of the groups suggest worsening of azotemia, hyperkalemia, hypermagnesemia and lethargy with evolution of obstruction. Temperature and heart rate were positively correlated with blood pH, base excess and bicarbonate, and inversely correlated with urea, creatinine, potassium and phosphorus. Lethargy was correlated with temperature, blood pH, base excess and bicarbonate.

As Disfunções do Trato Urinário Inferior (DTUI) é um termo amplo que descreve todo o espectro de distúrbios em qualquer uma das fases da micção, de causas neurogênicas, anatômicas e funcionais. A Terapia Comportamental é um método que permite acompanhar o desenvolvimento físico e emocional da criança e do adolescente. Objetivo: Analisar os resultados obtidos com a Terapia Comportamental em crianças e adolescentes portadores de disfunções do trato urinário inferior associada ao refluxo vesico- ureteral. Materiais e Métodos: A população foi composta por 109 crianças e adolescentes, 60% do sexo feminino e 40% do sexo masculino, entre 3 e 16 anos de idade. O tratamento aconteceu no período de 2007 a 2014, sendo realizado por 3 anos, com seguimento mensal por 1 ano. Foi realizada avaliação dos exames laboratoriais e de diagnóstico de imagem: Ultrassom Dinâmico da Micção e Uretrocistografia. A avaliação dos sintomas e o acompanhamento dos Hábitos por meio dos Diários da micção, das noites secas, do funcionamento intestinal, da Ingesta hídrica, dos alimentos, do café da manhã e do sono. A Identificação dos Transtornos de Comportamentos Externalizantes dos Pacientes com DTUI foi realizada por intermédio das Escala de Avaliação do Comportamento Infantil. A Terapia Comportamental baseou-se em: educação do corpo humano, conscientização do treinamento vesical, hidratação, dieta e organização do sono. Resultados: Quando a capacidade vesical atingiu a esperada, as crianças não apresentaram contrações do detrusor e a média de contrações do assoalho pélvico foi de 0,25. Apenas 0,005% das crianças apresentaram resíduo pós miccional. Entre 18 e 24 meses, os episódios de infecção do trato urinário desapareceram. A média da frequência miccional foi de 7 a 8x/dia e da ingesta hídrica de 1500ml/dia. 95% dos pacientes ingeriram média de 8 verduras e frutas/semana e apresentaram funcionamento intestinal >3x/semana. As perdas urinárias diurnas e noturnas desapareceram. Houve melhora da inatenção e socialização negativa que apresentou diferença estatisticamente significativa na avaliação inicial do tratamento. Conclusão: A Terapia Comportamental, por si só, é um método eficaz para melhorar e, até mesmo, curar os sintomas das Disfunções do Trato Urinário Inferior, prevenindo complicações futuras para o Trato Urinário Superior. / Lower urinary tract dysfunction (LUTD) is a broad term that describes the entire spectrum of disorders in any of the stages of urination with neurogenic, anatomical and functional causes. Behavioral Therapy is a method that allows monitoring the physical and emotional development of children and adolescents. Objective: To analyze the results obtained with Behavioral Therapy in children and adolescents with LUTD associated with vesicoureteral reflux. Materials and Methods: The study population consisted of 109 children and adolescents, 60% female and 40% male, aged 3 to 16 years old. The treatment occurred between 2007 and 2014, within a period of 3 years, with monthly follow-up for 1 year. Laboratory tests and diagnostic imaging by dynamic urinary ultrasound and urethrocystography were carried out. It was also performed evaluation of symptoms and monitoring of habits through diaries of urination, dry nights, intestinal functioning, water intake, food ingestion, breakfast and sleep. The identification of externalizing behavioral disorders of patients with LUTD was performed using the Child Behavior Assessment Scale. Behavioral Therapy was based on: education of the human body, awareness of bladder training, hydration, diet and sleep organization. Results: When the bladder capacity reached the expected level, the children did not present detrusor contractions and the mean number of contractions of the pelvic floor was 0.25. Only 0.005% of the children had post-urination residue. Urinary tract infection episodes disappeared between 18 and 24 months. The mean urination frequency was 7-8 times/day and the water intake was 1500 mL/day. As much as 95% of the patients ingested on average 8 vegetables and fruits per week and presented intestinal functioning >3x/week. Daytime and nighttime urine losses disappeared. There was an improvement of the inattention and negative socialization, with statistically significant difference from the initial evaluation of the treatment. Conclusion: Behavioral Therapy, by itself, is an effective method to improve and even resolve the LUTD symptoms, preventing future complications for the upper urinary tract.

INTRODUÇÃO: Neuromielite óptica (NMO) e suas formas limitadas são doenças desmielinizantes autoimunes do sistema nervoso central que acometem preferencialmente a medula espinhal e o nervo óptico. Várias formas clínicas do espectro da NMO (NMO-SD) tem sido descritas e incluem desde um evento único de mielite transversa longitudinalmente extensa (MTLE) à NMO recorrente. O comprometimento neurológico destes pacientes pode levar a diversas disfunções autonômicas, incluindo disfunção miccional. OBJETIVOS: Determinar a prevalência e as características dos sintomas do trato urinário inferior (STUI) e dos achados urodinâmicos em pacientes portadores de NMO-SD, e analisar suas associações com o grau de comprometimento neurológico e qualidade de vida (QV). MÉTODOS: Avaliamos 30 pacientes (23 mulheres e 7 homens) com diagnóstico estabelecido de NMO-SD, que foram convidados a participar do estudo a despeito de apresentarem ou não STUI. A avaliação neurológica foi realizada por meio da Escala Expandida do Estado de Incapacidade (EDSS), ressonância magnética de crânio e coluna vertebral, e dosagem de NMOIgG. Os STUI foram avaliados pelo Questionário de Avaliação da Bexiga Hiperativa (OAB-V8) e pelo Escore Internacional de Sintomas Prostáticos (IPSS). A qualidade de vida de forma geral foi avaliada pelo questionário de Satisfação com a Vida (LiSat-9). Todos os pacientes foram submetidos ao estudo videourodinâmico. RESULTADOS: A idade média dos pacientes foi de 41,1 ± 13,5 anos (intervalo de 13 a 70) e o tempo médio de duração da doença neurológica foi de 33,8 ± 30,8 meses (intervalo de 3 a 135). A avaliação neurológica mostrou pacientes com EDSS médio de 5,3 ± 1,8 (intervalo de 1 a 8,5). O escore médio do OAB-V8 foi de 17,5 ± 14,0 (intervalo de 0 a 40) e de 14,3 ± 10,6 (intervalo de 0 a 35) para o I-PSS. A média da QV geral medida pelo Lisat-9 foi de 38,9 ± 6,8 (intervalo de 26 a 49). Os STUI mais comuns foram urgência em 15 (50%) pacientes, noctúria em 15 (50%), jato urinário fraco em 15 (50%), intermitência em 14 (46,6%), esvaziamento incompleto em 13 (43,3%), hesitação em 13 (43,3%), aumento da frequência urinária em 13 (43,3%) e urge-incontinência em 5 (16%). Os achados urodinâmicos mais comuns foram hiperatividade detrusora (HD) com dissinergia detrusor-esfincteriana (DDE) em 11 (36,6%) pacientes, DDE sem HD em 7 (23,3%), HD sem DDE em 6 (20%), e incontinência urinária de esforço em 1 (3,3%). Cinco (16,6%) pacientes apresentaram estudo videourodinâmico sem anormalidades. Sintomas urinários medidos pelo IPSS e pelo OAB-V8 correlacionaram-se com maior comprometimento neurológico (r=0,42; p=0,018 e r=0,48; p=0,006 respectivamente). Pacientes portadores de DDE foram aqueles que mostraram maior comprometimento neurológico (p=0,027). Da mesma forma, pacientes dissinérgicos apresentaram maiores escores ao I-PSS (p=0,029) e ao OAB-V8 (p=0,008). Pacientes com maior comprometimento neurológico foram aqueles que apresentaram pior QV (r=-0,410; p=0,022). CONCLUSÃO: Encontramos alta prevalência de STUI e disfunção miccional em portadores de NMO, sendo DDE e a HD as anormalidades urodinâmicas mais frequentes. Dissinergia detrusor-esfincteriana e STUI se correlacionam com a gravidade da doença neurológica. A severidade da doença neurológica correlaciona-se com a qualidade de vida geral / INTRODUCTION: Neuromyelitis optica (NMO) and its limited forms are demyelinating autoimmune diseases of the central nervous system that preferentially affects the spinal cord and optic nerve. Several clinical forms of NMO spectrum disorders (NMO-SD) have been described and range from a limited event of longitudinally extensive transverse myelitis (LETM) to relapsing NMO. The neurological damage in these patients may lead to a range of autonomic dysfunctions, including voiding dysfunction. OBJECTIVES: To determine the prevalence and characteristics of the lower urinary tract symptoms (LUTS) and the urodynamic findings in patients with NMO-SD and analyze their correlations with the level of neurological damage and quality of life (QoL). METHODS: We evaluated 30 patients (23 women and 7 men) with an established diagnosis of NMO-SD based on stringent criteria. All patients were invited to participate irrespective of the presence of LUTS. Neurological impairment was assessed with the Expanded Disability Status Scale (EDSS), magnetic resonance imaging of the brain and spinal cord and NMO-IgG status. LUTS were evaluated with the Overactive Bladder V8 (OAB-V8) questionnaire and by the International Prostate Symptom Score (I-PSS). Quality of Life was evaluated using the Life Satisfaction questionnaire (LiSat-9). All patients underwent videourodynamics, transabdominal urinary tract sonography, urine culture and serum creatinine levels. RESULTS: The mean age of the patients was 41.1 ± 13.5 years (range 13 to 70) and the mean time of neurological disease duration was 33.8 ± 30.8 months (range 3 to 135). Neurological evaluation showed a mean EDSS score of 5.3 ± 1.8 (range 1 to 8.5). The mean OAB-V8 score was 17.5 ± 14.0 (range 0 to 40) and the mean I-PSS score was 14.3 ± 10.6 (range of 0 to 35). Mean general QoL measured by the Lisat-9 was 38.9 ± 6.8 (range 26 to 49). The most common urinary symptoms were urgency in 15 (50%) patients, nocturia in 15 (50%), weak urinary stream in 15 (50%), intermittence in 14 (46.6%), incomplete emptying in 13 (43.3%), hesitation in 13 (43.3%), increased urinary frequency in 13 (43.3%) and urge-incontinence in 5 (16,6%). The most frequent urodynamic findings were detrusor overactivity (DO) with sphincter dyssinergia (DSD) in 11 (36.6%) patients, DSD alone in 7 (23.3%), DO without DSD in 6 (20%) and stress urinary incontinence (SUI) in 1 (3.3%). Five (16.6%) patients had normal findings. Voiding dysfunction assessed by I-PSS and OAB-V8 increased with the degree of neurological impairment (r=0.42; p=0.018 and r=0.48; p=0.006 respectively). Patients with DSD had significantly higher symptoms based in the I-PSS (p=0.029) as well as the OAB- V8 scores (p=0.008) and greater neurological impairment (p=0.027). Patients with more severe neurological impairment were associated with worse Qol (r=-0.410; p=0.022). CONCLUSION: We have shown a high prevalence of LUTS and voiding dysfunction, with DSD and DO as the main urodynamic findings. Detrusor-sphincter dyssinergia and LUTS correlates with more severe neurological impairment. The severity of neurological impairment correlates with QoL
