RESUMO

Background: Hygiene-based practices of lubrication, genital cleansing, postcoital urination, and rectal douching are common behaviors among populations at higher risk of human immunodeficiency virus (HIV)/sexually transmitted infections (STI). Yet, the role these behaviors have on HIV/STI risk has not been well elucidated, especially among transgender women (TW) and gay, bisexual, and other men who have sex with men (GBMSM). Additionally, advances in biomedical strategies have heralded a new era of HIV/AIDS prevention that may be accompanied by behavioral changes that lead to decreases in condom usage and subsequent changes to STI sequelae. Nevertheless, many people at higher risk are not benefiting equally from these options, strengthening the need for more sustainable, evidence-based methods. Objectives: This study explored the knowledge, attitudes, and behaviors of hygiene-based practices, proven preventative methods, and preferred learning methods among Peruvian TW and GBMSM. Methods: 30 interviews and 50 questionnaires were conducted with TW (N=35), GBMSM (N=35), healthcare providers (N=5), and key community informants (N=5). Results: Most participants perceived hygiene-based practices to be common behaviors and a significant aspect of sexual wellbeing. Educational materials utilizing social media and hosting in-person events were also viewed favorably, with value to enhancing HIV/STI knowledge. Conclusions: Several barriers to autonomy surfaced in the data, including systemic disparities to adequate HIV/STI services, top vs. bottom social dynamics, and PrEP accessibility issues. Continued work is needed to address the barriers to the acceptability, feasibility, and potential efficacy of hygiene-based practices, biomedical/barrier strategies, and L 3 +.

RESUMO

OBJECTIVES: The objective of this paper is to evaluate changes in lower urinary tract symptoms (LUTS), severity of pain and urodynamic parameters after minimally invasive nerve-sparing surgery for patients with endometriosis. METHODS: We analyzed 143 patients undergoing minimally invasive nerve-sparing surgery for endometriosis excision (laparoscopy/robot-assisted). The endometriosis was confirmed by preoperative clinical evaluation, magnetic resonance imaging (MRI) showing at least one lesion deeper than 5 mm, and histological confirmation after laparoscopy. We evaluated three points prior and after surgery: LUTS parameters according to the International Urogynecological Association; urodynamic measures of storage and voiding and the severity of the dyspareunia, dyschezia and dysmenorrhea assessed on a self-reported 11-point numeric rating scale. The Wilcoxon signed rank and McNemar tests were used for statistical analyses (p < 0.05). RESULTS: We observed significant improvements in LUTS after the surgery with postoperative symptom-free probabilities in urgency (64.5%), daytime frequency (38.5%), and dysuria (87.1%). However, slow stream prevalence increased significantly postsurgery (p = 0.022), with a 20.5% risk of asymptomatic patients developing this symptom. Urodynamic responses varied; for instance, maximum cystometric capacity improved significantly (p = 0.004), while postvoiding residual worsened (p = 0.006). Significant worsening in postvoiding residual occurred in women with normal preoperative values (p = 0.002), with a 17.7% risk of normal values becoming abnormal. Compliance or maximum cystometric capacity not considered normal preoperatively showed significant improvements (p < 0.001), but the risk of normal values becoming abnormal after surgery was 14.5%. CONCLUSION: The minimally invasive nerve-sparing surgery for endometriosis excision shows improvement in lower urinary tract symptoms, urodynamics parameters and severity of pain. The majority of patients became asymptomatic in the postoperative period. When compared to the benefits of the patients' surgical treatment, particularly when considering the reduction of pain, the risks of the lower urinary tract treatment seem to be acceptable. The surgical intervention seems to be a safe alternative in patients with endometriosis, although studies with larger samples are needed to confirm these findings.

RESUMO

Background: The diagnosis of bladder outlet obstruction (BOO) in women is a challenge for functional urology. In Mexico there are few data that report the prevalence of OTSV in women, being up to 24% in a group of patients. Objective: The aim of this study is to compare six different definitions of bladder outlet obstruction and evaluate the interobserver agreement in an educational setting. Material and Methods: Urodynamic studies (UDS) of women with and without diagnosis of BOO were retrospectively assesed. Farrar, Chassagne, Lemack, Defreitas, Blavais and Groutz, Solomon-Greenwell definitions were evaluated. All UDS were independently reviewed by 5 observers. The easiest, the hardest and the fastest were chosen. Interobserver agreement to classify the patients as obstructed was assessed by kappa reliability statistical analysis. We classified the type of mistakes the participants made; error of interpretation and miscalculation. Results: A total of 28 urodynamic studies were reviewed. All observers had a substantial agreement (0.64-0.78) to classify BOO using all but Lemack and Solomon-Greenwell definitions. A total 120 errors from 840 responses were found; 45.8% errors of interpretation of UDS and 54.1% miscalculation of the equation. Finally, all the participants chose the Solomon-Greenwell was the most difficult definition. Conclusion: Chassagne, Defreitas and Farrar definitions proved substantial interobserver agreement. Solomon-Greenwell and Lemack´s definitions had the highest number of pitfalls and the lowest level of agreement.

Introducción: el diagnóstico de obstrucción de tracto de salida vesical (OTSV) en mujeres supone un reto para la urología funcional. En México existen pocos datos que reporten la prevalencia de OTSV en mujeres, siendo de hasta el 24% en un grupo de pacientes. Objetivo: comparar seis definiciones diferentes de obstrucción de tracto de salida vesical (OTSV) en mujeres y evaluar la concordancia entre observadores en un entorno educativo. Material y métodos: evaluación retrospectiva de estudios urodinámicos de mujeres con y sin diagnóstico de OTSV. Se evaluaron las definiciones de Farrar, Chassagne, Lemack, Defreitas, Blavais y Groutz y Solomon-Greenwell. A todos los participantes se les brindó un taller teórico-práctico para analizar los estudios urodinámicos en su fase de flujo-presión y diagnosticar la OTSV. Los estudios urodinámicos fueron revisados de forma independiente por cinco observadores. La concordancia interobservador para clasificar a los pacientes como obstruidos se evaluó mediante análisis estadístico de confiabilidad kappa. Se clasificó el tipo de errores que cometieron los participantes, error de interpretación de estudios urodinámicos y error de cálculo en los criterios. Resultados: se revisaron en total 28 estudios urodinámicos. Todos los observadores tuvieron una concordancia buena de (0.64-0.78) para clasificar OTSV usando todas las definiciones excepto las de Lemack y Solomon-Greenwell. Se encontraron un total de 120 errores de 840 respuestas, 45.8% errores de interpretación y 54.1% error de cálculo de la ecuación. Los participantes eligieron la definición de Solomon-Greenwell, la más difícil. Conclusión: las definiciones de Chassagne, Defreitas y Farrar demostraron una concordancia sustancial entre observadores. Las definiciones de Solomon-Greenwell y Lemack tuvieron el mayor grado de dificultad y el menor nivel de acuerdo.

Abstract Objective To describe the sociodemographic profile, access and interest in receiving online information about bladder and bowel dysfunction as well as understand the experience of families of children and adolescents affected by this dysfunction. Methods This is a multi-methodological study carried out in an outpatient clinic of Advanced Nursing Practice in uropediatrics of a teaching hospital in midwestern Brazil. Results The experience of families of children with bladder and bowel dysfunction points to a negative impact on everyday life, which may be related to sociodemographic conditions, lack of knowledge of families about the symptoms and stigmas associated with its manifestation. To this end, access to online information is a potential support tool to improve the experience of children's families with the symptoms. Conclusion The results express children's sociodemographic characterization and their family and the access and interest in receiving information on the internet about bladder and bowel dysfunction, which may be important for compliance and perception of improvement in symptoms, reflecting on family experience. Therefore, nurses who work in the context of uropediatrics care need to innovate in their approach and implement new care modalities or health interventions, mainly through the incorporation of internet-based technologies, aimed at improving the quality of life of both the families and children with bladder and bowel dysfunction.

RESUMO

ABSTRACT Introduction: Upper airway obstruction (UAO) is a common condition in all pediatric population, with a 27% prevalence. Primary monosymptomatic nocturnal enuresis (PMNE) is a condition related to UAO in 8% to 47% of these children. The specific pathophysiological mechanism of this bond is not well understood. Some authors suggest a connection between brain natrituretic peptide (BNP) and anti-diuretic hormone (ADH) during sleep. The aim of this study was to evaluate hormone profile (ADH and BNP) and improvement in dry nights in a sample of children before and after surgical treatment of the UAO. Methods: This is a longitudinal prospective interventionist study in children, 5 to 14 years of age, with UAO and PMNE recruited in a specialty outpatient clinic. Children presenting UAO and PMNE were evaluated with a 30-day dry night diary and blood samples were collected to evaluate ADH and BNP before and after upper airway surgery. Data were analyzed prior to surgery and 90-120 days after surgery. Results: Twenty-one children with a mean age of 9.7 years were included. Mean BNP before surgery was 116.5 ± 126.5 pg/mL and 156.2 ± 112.3 pg/mL after surgery (p<0.01). Mean ADH was 5.8 ± 3.2 pg/mL and 14.6 ± 35.4 before and after surgery, respectively (p=0.26). The percentage of dry nights went from 32.3 ± 24.7 before surgery to 75.4 ± 33.4 after surgery (p<0.01). Conclusion: Surgery for airway obstruction contributed to an increase in BNP without increasing ADH. A total of 85.8% of the children presented partial or complete improvement of their enuresis.

RESUMO

The purpose of this study was to determine which socio-demographic, clinical, or functional factors are associated with urgency urinary incontinence (UUI) over 20-years of follow-up in a community-dwelling sample of Mexican American women aged 65 years and older without UUI at baseline. We included 1,358 women participants from the Hispanic Established Population for the Epidemiologic Study of the Elderly study conducted in the southwestern of US (Arizona, California, Colorado, New Mexico, and Texas). Measures included self-reported UUI, socio-demographics, smoking status, body mass index, medical conditions, depressive symptoms, physical and cognitive function, and handgrip strength. We used generalized estimating equation models to estimate the odds ratio (OR) and 95% Confidence Interval (CI) of UUI as a function of socioeconomic, clinical, and functional factors. Self-reported UUI increased from 3.1% to 21.9% from baseline (1993/1994) to follow-up (2012/2013). Current smokers, obesity, arthritis, previous heart attacks, and depressive symptoms were factors associated with greater odds of UUI over time. Identification of these factors can help clinicians determine those at high risk of developing UUI. Preventing and/or treating the risk factors early may delay UUI and increase quality of life in this underserved population.

RESUMO

ABSTRACT Objective: to assess the effect of a Nursing Rehabilitation program on the urinary incontinence management of women after a CVA. Method: quantitative, quasi-experimental, and longitudinal study conducted in a convalescence unit in the Viana do Castelo district, Portugal, between September 2018 and March 2019. The sample included women (n=30) aged between 45 and 90, experiencing urinary incontinence after a CVA, assigned to two groups: experimental group (n=15) and control group (n=15). The functional rehabilitation program was applied to the experimental group for 4 weeks. The program comprises behavioral changes and an exercise plan to strengthen pelvic floor muscles, and the impact of urinary incontinence was assessed before and after the intervention. Results: a statistically significant correlation was found between the level of functional disability and the impact of urinary incontinence (r=-0.499; p=0.005). Hence, the level of functional disability influences the impact of urinary incontinence on quality of life. The functional rehabilitation program implemented in the experimental group obtained positive results and decreased the frequency (t=6.985, p=0.000) and amount (Z=-2.762, p=0.006) of urine loss. Conclusion: the functional rehabilitation program positively impacted and decreased the frequency and amount of urine loss.

RESUMO

INTRODUCTION AND HYPOTHESIS: A voiding diary is a method to investigate lower urinary tract symptoms. The purpose was to elaborate a descriptive analysis of nonpaid voiding diaries for mobile applications and to compare them regarding their quality. METHODS: We searched the platforms of iTunes (Apple Inc., Brazil) and Google Play (Google Inc., Brazil) using the keywords: "voiding diary," "bladder diary," "urinary diary," "urinary incontinence," and "pelvic floor." Inclusion criteria were: apps free of charge and specific for voiding diaries in the Portuguese, Spanish, French, or English language. Exclusion criteria were: access or technical problems and pediatric apps. We quantitatively analyzed and compared the apps with each other according to their functionality features and voiding diary topics (type and volume of fluid intake, voiding episodes and volume, type and episodes of incontinence, amount of leakage, urgency, and use of pads and nocturia). We rated the apps using the Mobile App Rating Scale (MARS), whose scores for each feature vary from 1 (worst score) to 5 (best score). RESULTS: Fifty-five apps were eligible; 16 were included for analyses. None presented all 11 topics of the voiding diary, and the median number of available features was 6 (3.75-7). "Incontinence episodes" was present in eight apps, and "nocturia" was present in five. The mean score of apps ranged between 1.7 and 4.5. CONCLUSION: There is variation in the content of voiding topics among the apps. Patients and professionals should choose the app based on the topics of most or particular interest.

RESUMO

SUMMARY OBJECTIVES To prospectively investigate the alterations and normal ranges of ureteral jet dynamics after double-J-stent (DJS) removal in patients who underwent renal transplantation (RTx). METHODS Patients who underwent RTx were prospectively evaluated between November 2017 and June 2018. After RTx, Doppler ultrasonography (D-US) was performed on all patients after DJS removal. Renal artery resistive index (RA-Ri), renal pelvis anterior-posterior diameter (RP-APD), pelvicalyceal system dilation (PCSD), and ureteral jet flow dynamics (maximum and average velocity; JETmax and JETave) were measured by D-US. Also, patients' demographics, estimated glomerular filtration rate (eGFR) levels, and acute rejection were investigated in the study. Patients were assessed two different times by D-US, about 6 and 12 weeks after DJS removal, and the two different measurements were compared with the Wilcoxon test and Chi-square test. RESULTS A total of 25 patients were evaluated in the study. Nonobstructive PCSD rate (12% vs 8%), JETave (18.8 vs 12.9 cm/sec), and JETmax (29.2 vs 20 cm/sec) levels were significantly decreased (p values are 0.01, 0.010 and 0.014, respectively). In addition, monophasic and square pattern rates were significantly observed to increase over time (p=0.035); however, ureteral jet patterns were correlated between the two different D-US measurements (R=0.225, p=0.032). CONCLUSION After RTx, dilation rate and ureteral jet flow velocities were significantly decreased, and monophasic and square JETpattern rates were significantly increased over time. Ureteral jet dynamics can provide useful information about the follow-up of peristaltic activity in the pelvic-ureteric system.

RESUMO OBJETIVOS Investigar prospectivamente as alterações e as variações normais da dinâmica do jato ureteral após a remoção do J-stent duplo (DJS) em pacientes submetidos a transplante renal (RTx). MÉTODOS Pacientes submetidos a RTx foram avaliados prospectivamente entre novembro de 2017 e junho de 2018. Após o RTx, o D-US foi realizado em todos os pacientes após a remoção do DJS. Índice de resistência da artéria renal (RA-Ri), diâmetro ântero-posterior da pelve renal (AP-DPR), dilatação do sistema pelvicaliceal (PCSD) e dinâmica do jato ureteral (velocidade máxima e média; JETmax e JETave) foram medidos por D-US. Além disso, a demografia dos pacientes, os níveis estimados de taxa de filtração glomerular (eGFR) e a rejeição aguda foram investigados no estudo. Os pacientes foram avaliados em dois momentos diferentes pelo D-US, cerca de 6 e 12 semanas após a remoção do DJS, e as duas medidas diferentes foram comparadas com o teste de Wilcoxon e o teste do qui-quadrado. RESULTADOS Um total de 25 pacientes foi avaliado no estudo. Taxa de PCSD não obstrutiva (12% vs. 8%), JETave (18,8 vs. 12,9 cm/seg) e JETmax (29,2 vs. 20 cm/seg), os níveis foram significativamente diminuídos (valores de p são 0,01, 0,010 e 0,014, respectivamente). Além disso, as taxas de padrão monofásico e quadrado foram significativamente observadas para aumentar ao longo do tempo (p=0,035); no entanto, padrões de jato ureteral foram correlacionados entre as duas diferentes medidas D-US (R=0,225, p=0,032). CONCLUSÃO Após o RTx, a velocidade de dilatação e as velocidades de fluxo do jato ureteral foram significativamente diminuídas e as taxas de JET padrão monofásico e quadrado foram significativamente aumentadas ao longo do tempo. A dinâmica do jato ureteral pode fornecer informações úteis sobre o acompanhamento da atividade peristáltica no sistema pélvico-ureteral.

RESUMO

Resumen La disfunción neurogénica del tracto urinario inferior abarca una amplia variedad de trastornos que se caracterizan por una disfunción de la fisio logía de la micción. Muchas veces su diagnóstico no suele ser fácil y suele primero diagnosticarse la disfunción del tracto urinario y posteriormente encontrar el diagnóstico del trastorno neurológico que lo ocasiona. Todos estos trastornos terminan afectando gravemente la calidad de vida de las pacientes, por sus complicaciones propias y las derivadas de la condición. Algunas de estas complicaciones son infecciones urinarias recurrentes, incontinencia urinaria, disfunción del vaciamiento vesical, estenosis uretral y enfermedad renal progresiva con daño irreversible. Los objetivos de esta revisión son exponer las diferentes alteraciones neurológicas según la cla sificación SALE y describir cómo afectan la fisiología de la micción.

Abstract Neurogenic dysfunction of the lower urinary tract encompasses a wide variety of disorders, which are characterized by a dysfunction of the urination physiology. In many times the diagnosis of this type of pathologies is usually not so easy, and the urinary tract dysfunc tion can be diagnosed first and secondarily find the diagnosis of the neurological disorder that causes it. All these disorders end up se riously affecting the quality of life of these patients, due to their own complications and the complications derived from the condition. Some of the associated complications are recurrent urinary tract infections, urinary incontinence and bladder emptying dysfunction, urethral stricture and progressive kidney disease with irreversible damage. The location of the neurological lesion does not always de termine the type of inferior urinary dysfunction. The objective of this review is to expose the different neurological alterations according to the SALE classification and describe how they affect the physiol ogy of urination.

RESUMO

ABSTRACT Objectives To determine the differences between voiding symptoms obtained by open anamnesis (VS-Open) versus voiding symptoms obtained by directed anamnesis (VS-Directed) to predict voiding dysfunction in women. Materials and Methods Retrospective study of women with prior anti-incontinence surgery evaluated during 5 years. In a standardized clinical history taking, each patient was asked to answer question number five of the UDI-6 questionnaire ("Do you experience any difficulty emptying your bladder?"). If the answer was positive, the following voiding symptoms spontaneously described by the patient were documented: slow urine stream, straining to void, intermittent stream and feeling of incomplete bladder emptying, which were considered VS-Open. If the answer to this question was negative or if the patient had not reported the four voiding symptoms, she was asked in a directed manner about the presence of each o Ninety-one women are analyzed. Eighteen patients presented voiding dysfunction (19.8%), There was a statistical association between voiding dysfunction and the presence of any VS-Open (p = 0.037) and straining to void obtained by open anamnesis (p = 0.013). Sensitivity, specificity, PPV, NPV, positive likelihood ratio and negative likelihood ratio, respectively, were 44.4% and 27.8%, 80.8% and 94.5%, 36.3% and 55.6%, 85.5% and 84.1%, 2.324 and 5.129, and 0.686 and 0.764. There was no statistical association between voiding dysfunction and VS-Directed. Conclusions VS-Open may predict better voiding dysfunction than VS-Directed in women.

RESUMO

A significant workforce shortage of urologists available to serve the US population has been projected to occur over the next decade. Accordingly, much of the management of urologic patients will need to be assumed by other specialties and practitioners. Since primary care physicians are often first evaluate common urologic complaints, it makes sense that these physicians are in an excellent position to intervene in the management of these patients when appropriate. One of the most common complaints in urology is voiding dysfunction. The incidence of voiding dysfunction increases with age, with conservative estimates showing that over 50% of elderly patients suffer. Despite this high prevalence and its negative impact on quality of life, however, few seek or receive treatment, as many do not readily disclose these impactful yet personal symptoms. We sought to summarize the typical presentation, evaluation, assessment and therapeutic options for both male and female patients presenting with voiding dysfunction.

RESUMO

BACKGROUND: The removal of an indwelling urinary catheter is indicated as soon as possible to prevent complications. However, acute urinary retention is little studied among intensive care patients. AIMS: The aim of this study was to determine the incidence and risk factors for acute urinary retention after the removal of an indwelling urinary catheter in critically ill patients. DESIGN: This single-centre prospective study included adult critically ill adult surgical and medical patients. METHODS: All patients had an indwelling catheter for more than 48 h and indication of its removal by the attending physician. Acute urinary retention was defined as a bladder volume greater than 400 mL determined by ultrasound or intermittent urinary catheterization. A multivariate logistic regression was performed to analyse the possible risk factors for acute urinary retention. RESULTS: We included 85 patients from July 2014 to May 2015, most of them surgical (71·8%). Acute urinary retention occurred in 26 patients (30·6%). The use of hypnotics (midazolam or propofol given as continuous infusion) [OR 14·87 (95% CI 1·32-167·79); p = 0·029], indwelling catheterization for more than 7 days [OR 9·87 (95% CI 2·97-32·85); p < 0·001] and bed restraint [OR 9·43 (95% CI 1·07 to 83·33); p = 0·043] were all independent risk factors for acute urinary retention. CONCLUSION: The incidence of acute urinary retention is high, and the main risk factors for its occurrence are prolonged use of urinary indwelling catheter, bed confinement and the use of hypnotics. RELEVANCE TO CLINICAL PRACTICE: Patients with risk factors should be kept under surveillance after the removal of indwelling urinary catheter for early identification of acute urinary retention and thus prevention of related complications.

Pandora"s syndrome is a multifactorial disorder in which other systemic aetiologies may influence clinical signs in a target organ. In cats with chronic and idiopathic lower urinary tract disease, diagnosis requires a criteria of exclusion and must fulfil at least four other criteria as a confirmation of the diagnostic. Fundamental treatment of the syndrome is based on the elimination of stress factors as well as environmental enrichment.

A síndrome de Pandora é uma doença de caráter multifatorial onde outras etiologias sistêmicas podem influenciar sinais clínicos em um órgão alvo. Em gatos com doença do trato urinário inferior crônicas e idiopáticas, o diagnóstico além de ser por exclusão, deve preencher no mínimo três outros critérios para que a síndrome seja ocorrente. Seu tratamento fundamental baseia-se na eliminação de fatores estressantes bem como o enriquecimento ambiental.

El síndrome de Pandora es un disturbio multifatorial, en el cual otras etiologías pueden influenciar en signos clínicos en un órgano diana. En los gatos con enfermedad del tracto urinario inferior crónica e idiopática, el diagnostico requiere criterios de exclusión y debe completar al menos otros cuatro criterios para su confirmación. El tratamiento fundamental de esta síndrome es basado en la eliminación de los factores de estrés, además de enriquecimiento ambiental.

RESUMO

ABSTRACT Objective The study was designed to determine the effect of low frequency (2.5Hz) intraurethral electrical stimulation on bladder capacity and maximum voiding pressures. Materials and Methods The experiments were conducted in 15 virgin female Sprague-Dawley rats (220–250g). The animals were anesthetized by intraperitoneal injection of urethane (1.5g/kg). Animal care and experimental procedures were reviewed and approved by the Institutional Animal Care and Use Committee of Antwerp University (code: 2013-50). Unipolar square pulses of 0.06mA were used to stimulate urethra at frequency of 2.5Hz (0.2ms pulse width) in order to evaluate the ability of intraurethral stimulation to inhibit bladder contractions. Continuous stimulation and intermittent stimulation with 5sec ‘‘on’’ and 5sec ‘‘off’’ duty cycle were applied during repeated saline cystometrograms (CMGs). Maximum voiding pressures (MVP) and bladder capacity were investigated to determine the inhibitory effect on bladder contraction induced by intraurethral stimulation. Results The continuous stimulation and intermittent stimulation significantly (p<0.05) decreased MVP and increased bladder capacity. There was no significant difference in MVP and bladder capacity between continuous and intermittent stimulation group. Conclusions The present results suggest that 2.5Hz continuous and intermittent intraurethral stimulation can inhibit micturition reflex, decrease MVP and increase bladder capacity. There was no significant difference in MVP and bladder capacity between continuous and intermittent stimulation group.

RESUMO

Objective To re-examine the function of the urinary bladder in vivoas well as to determine the functional and biochemical characteristics of bladder muscarinic receptors in long-term alloxan-induced diabetes rats.Methods Two-month-old male Wistar rats were injected with alloxan and the animals showing blood glucose levels >300mg/dL together with age-paired untreated animals were kept for 11 months. Body weight, bladder weight, blood glucose, and urinary volume over a period of 24 hours were determined in both groups of animals. A voiding cystometry in conscious control and diabetic rats was performed to determine maximal micturition pressure, micturition contraction interval and duration as well as voided and post-voiding residual volume. In addition, concentration-response curves for bethanechol in isolated bladder strips, as well as [3H]-N methyl-scopolamine binding site characteristics in bladder homogenates were determined.Results Mean bladder weight was 162.5±21.2mg versus 290±37.9mg in control and treated animals, respectively (p<0.05). Micturition contraction amplitude (34.6±4.7mmHg versus 49.6±2.5mmHg), duration (14.5±1.7 seconds versus 23.33±4.6 seconds) and interval (87.5±17.02 seconds versus 281.11±20.24 seconds) were significantly greater in alloxan diabetic rats. Voided urine volume per micturition contraction was also significantly higher in diabetic animals. However the post-voiding residual volume was not statistically different. Bethanechol potency (EC50 3µM versus 5µM) and maximal effect (31.2±5.9g/g versus 36.1±6.8g/g) in isolated bladder strips as well as number (169±4fmol/mg versus 176±3fmol/mg protein) and affinity (0.69±0.1nM versus 0.57±0.1nM) of bladder muscarinic receptors were also not statistically different.Conclusion Bladder function in vivo is altered in chronic alloxan-induced diabetes rats without changes in functional and biochemical characteristics of bladder muscarinic receptors.

Objetivo Reestudar o funcionamento da bexiga in vivo e determinar as características funcionais e bioquímicas dos receptores muscarínicos vesicais de ratos com diabetes crônico induzido por aloxana.Métodos Ratos Wistar de dois meses de idade receberam injeção de aloxana, e os animais que apresentaram glicemia >300mg/dL foram mantidos por 11 meses junto de outros não tratados e pareados por idade. Nos dois grupos de animais, peso corpóreo, peso da bexiga, glicemia e volume urinário de 24 horas foram medidos. Em ambos os grupos, realizou-se a cistometria miccional em animais não anestesiados. Foram determinados os seguintes parâmetros: pressão máxima de micção, intervalo e contração de micção, bem como o volume de esvaziamento e o volume residual pós-miccional. Além disso, foram determinadas as curvas de concentração-resposta a betanecol em preparações isoladas de bexiga e também as características dos sítios de ligação da [3H]-N-metil-escopolamina em homogenatos de bexiga.Resultados O peso médio da bexiga foi de 162,5±21,2mg versus290±37,9mg nos animais controles e tratados, respectivamente (p<0,05). A amplitude de contração (34,6±4,7mmHg versus 49,6±2,5mmHg), a duração (14,5±1,7 segundos versus 23,33±4,6 segundos) e o intervalo (87,5±17,02 segundos versus 281,11±20,24 segundos) de micção foram significantemente maiores nos ratos tratados com aloxana. O volume de urina eliminada durante a contração miccional também foi maior nos animais diabéticos. Contudo, o volume residual pós-miccional não foi estatisticamente diferente. Não foram observadas diferenças na resposta ao betanecol (EC50 3µM versus 5µM) e no seu efeito máximo (31,2±5,9g/g versus 36,1±6,8g/g) em preparações isoladas de bexiga, bem como no número total (169±43fmol/mgversus 176±3fmol/mg) e na afinidade (0,69±0,1nMversus 0,57±0,1nM) dos receptores muscarínicos da bexiga.Conclusão O funcionamento da bexiga in vivo está alterado no diabetes crônico induzido por aloxana, porém sem alterações funcionais e bioquímicas nos receptores muscarínicos da bexiga.
