A Korean Postmarketing Study Assessing the Effectiveness of OnabotulinumtoxinA for the Treatment of Neurogenic Detrusor Overactivity or Idiopathic Overactive Bladder Using a Validated Patient-Reported Outcome Measure / 대한배뇨장애요실금학회지

PURPOSE: OnabotulinumtoxinA has demonstrated efficacy and safety in the treatment of urinary incontinence (UI) associated with neurogenic detrusor overactivity (NDO) and idiopathic overactive bladder (OAB); however, real-world evidence is limited. This postmarketing surveillance study aimed to assess the effectiveness and safety of onabotulinumtoxinA in Korean patients with UI associated with NDO or OAB with an inadequate response or intolerance to anticholinergics. METHODS: Patients received 200 U (NDO) or 100 U (OAB) of onabotulinumtoxinA. Effectiveness (assessed using the validated International Consultation on Incontinence Questionnaire-Short Form [ICIQ-SF]) and safety were assessed for 1–4 months after onabotulinumtoxinA administration. RESULTS: Overall, 686 patients (NDO, 161; OAB, 525) comprised the safety population; of these, 612 patients were analyzed for effectiveness. There was a significant decrease (P5 points from baseline in the ICIQ-SF score was observed in 64.9% and 47.3% of patients in the NDO and OAB groups, respectively. Following treatment, 59.9% in the NDO group and 43.0% in the OAB group were dry. There was no effect of age on effectiveness in either group. Only 10 adverse drug reactions (ADRs) were reported in 5.6% of NDO patients and 20 ADRs in 3.2% of OAB patients. Most ADRs in both groups were related to the lower urinary tract such as dysuria (NDO, 1.2%; OAB, 0.6%) and urinary retention (NDO, 0.6%; OAB, 1.5%). CONCLUSIONS: Effectiveness and safety of onabotulinumtoxinA in Korea in a real-world setting was demonstrated.

Linguistic Validation of the Intermittent Self-catheterization Questionnaire for Patients With Neurogenic Bladder Who Perform Intermittent Catheterization for Voiding Dysfunction / 대한배뇨장애요실금학회지

PURPOSE: In recent years, the importance of patient satisfaction and quality of life—referred to as patient-related outcomes— has been emphasized, in addition to the evaluation of symptoms and severity through questionnaires. However, the questionnaires that can be applied to Korean patients with neurogenic bladder are limited. Therefore, the current study linguistically validated the Intermittent Self-Catheterization Questionnaire (ISC-Q) as an instrument to evaluate the quality of life of Korean patients with neurogenic bladder who regularly perform clean intermittent catheterization (CIC). METHODS: The validation process included permission for translation, forward translations, reconciliation, backward translation, cognitive debriefing, and proofreading. Two bilingual translators independently translated the original version of the ISC-Q into Korean and then combined the initial translations. A third bilingual translator performed a backward translation of the reconciled version into English. Five Korean-speaking patients with neurogenic bladder carried out the cognitive debriefing. RESULTS: During the forward translation process, the 24 questions of the ISC-Q were translated into 2 Korean versions. The terms used in each version were adjusted from the original version to use more conceptually equivalent expressions in Korean. During the backward translation process, several changes were involving substitutions of meaning. In the cognitive debriefing process, 5 patients were asked to complete the questionnaire. All patients agreed that the questionnaire explained their situation well. CONCLUSIONS: This study presents a successful linguistic validation of the Korean version of the ISC-Q, which could be a useful tool for evaluating treatment satisfaction in patients with neurogenic bladder performing CIC regularly.

Social Determinants of Health in the lives of urinary catheter users / Determinantes Sociales de Salud en la vida de usuarios de cateterismo urinario / Determinantes Sociais de Saúde na vida de usuários de cateterismo urinário

ABSTRACT Objective: To identify the influence of social determinants of health on the life conditions of patients who use intermittent urinary catheters. Method: This was a descriptive study conducted in a rehabilitation center with 243 neurogenic bladder patients who used clear intermittent urinary catheters. The study was carried out between March 2012 and October 2015, using interviews based on semi-structured instruments, and data analysis using descriptive statistics. Results: Most of the patients were men, between 16 and 64 years old, single, with an elementary education level, and a monthly household income of 2 to 3 minimum wages. The results show that the social determinants of health were related to socioeconomic, demographic, and health factors. Conclusion: The findings indicate a complex relationship between social determinants of health and the life conditions of patients who use clean intermittent urinary catheters, presenting greater vulnerability related to some aspects of health conditions.

Epidemiology of cauda equina syndrome. What changed until 2015 / Epidemiologia da síndrome da cauda equina. O que mudou até 2015

ABSTRACT Objective: The primary objective of this study was to analyze the characteristics and outcomes of cases admitted to hospital with cauda equina syndrome (CES) at the Institute of Orthopedics and Traumatology (IOT) from 2005 to 2015. Secondly, this article is a continuation of the epidemiological work of the same base published in 2013, and will be important for other comparative studies to a greater understanding of the disease and its epidemiology. Methods: This was a retrospective study of the medical records of admissions due to CES at IOT in the period 2005-2015 with diagnosis of CES and neuropathic bladder. The following variables were analyzed: gender, age, etiology of the disease, topographic level of the injury, time interval between injury and diagnosis, presence of neurogenic bladder, time interval between diagnosis of the CES and surgery, and reversal of the deficit or of the neurogenic bladder. Results: Since this is a rare disease, with a low global incidence, it was not possible, just with the current study to establish statistically significant correlations between the variables and outcomes of the disease. However, this study demonstrates the shortcomings of the Brazilian public health system, both with the initial management of these patients and the need for urgent surgical treatment. Conclusion: The study shows that despite well-defined basis for the conduct of CES, a higher number of sequelae caused by the pathology is observed in Brazil. The delay in diagnosis and, therefore, for definitive treatment, remains as the major cause for the high number of sequelae. Level of evidence: 4, case series.

RESUMO Objetivo: Analisar as características e os desfechos dos casos internados por síndrome da cauda equina (SCE) no Instituto de Ortopedia e Traumatologia (IOT) da Faculdade de Medicina da Universidade de São Paulo de 2005-2015. Secundariamente, este artigo é a continuação do trabalho epidemiológico de mesma base publicado em 2013 e servirá de base para outros estudos comparativos com vistas a um entendimento maior da doença e de sua epidemiologia. Métodos: Estudo retrospectivo dos prontuários das internações por SCE no IOT de 2005 a 2015 com diagnósticos de SCE e bexiga neuropática. As seguintes variáveis foram analisadas: sexo, idade, etiologia da doença, nível topográfico da lesão, tempo de história da lesão até o diagnóstico, presença de bexiga neurogênica, tempo entre o diagnóstico da SCE e a cirurgia e reversão do déficit ou da bexiga neurogênica. Resultados: Por se tratar de uma doença rara, com uma incidência global baixa, não foi possível, somente com o estudo atual, estabelecer correlações estatisticamente significativas entre as variáveis analisadas e os desfechos da doença. Porém, este estudo continua a evidenciar as deficiências do sistema público de saúde brasileiro, tanto no manejo inicial desses pacientes quanto na necessidade de tratamento cirúrgico de urgência. Conclusão: O trabalho mostra que, apesar de bem definidas as bases para conduta da SCE, observa-se no Brasil um número maior de sequelas causadas pela patologia. O atraso no diagnóstico e, a partir desse, no tratamento definitivo mantém-se como a causa para o alto número de sequelas. Nível de evidência: 4, série de casos.

Complication of epiduroscopy: a brief review and case report

Epiduroscopy is defined as a percutaneous, minimally invasive endoscopic investigation of the epidural space. Periduroscopy is currently used mainly as a diagnostic tool to directly visualize epidural adhesions in patients with failed back surgery syndrome (FBSS), and as a therapeutic action in patients with low back pain by accurately administering drugs, releasing inflammation, washing the epidural space, and mechanically releasing the scars displayed. Considering epiduroscopy a minimally invasive technique should not lead to underestimating its potential complications. The purpose of this review is to summarize and explain the mechanisms of the side effects strictly related to the technique itself, leaving aside complications considered typical for any kind of extradural procedure (e.g. adverse reactions due to the administration of drugs or bleeding) and not fitting the usual concept of epiduroscopy for which the data on its real usefulness are still lacking. The most frequent complications and side effects of epiduroscopy can be summarized as non-persistent post-procedural low back and/or leg discomfort/pain, transient neurological symptoms (headache, hearing impairment, paresthesia), dural puncture with or without post dural puncture headache (PDPH), post-procedural visual impairment with retinal hemorrhage, encephalopathy resulting in rhabdomyolysis due to a dural tear, intradural cyst, as well as neurogenic bladder and seizures. We also report for first time, to our knowledge, a case of symptomatic pneumocephalus after epiduroscopy, and try to explain the reason for this event and the precautions to avoid this complication.

Relation of Urinary Retention and Functional Recovery in Stroke Patients During Rehabilitation Program

OBJECTIVE: To investigate the relationship between urinary retention and short-term functional recovery in subacute stage after stroke. METHODS: The medical records of 94 patients admitted to the rehabilitation unit of Korea University Guro Hospital were reviewed retrospectively. The postvoid residual urine (PVR) was measured at least once a day using a bladder scan, and urinary retention (UR) was defined when the daily PVR volume consistently checked more than 100 mL. Clinical data and functional outcomes of patients in the rehabilitation ward were collected. Functional outcomes were measured using the Mini-Mental State Examination (MMSE), Berg Balance Scale (BBS), Functional Ambulation Category (FAC) level, Fugl-Meyer Assessment (FMA), and Modified Barthel Index (MBI) at admission (or transfer) and discharge. The data of patients with and without urinary retention were compared and analyzed. RESULTS: Of the 94 participants, 25 patients were classified to the UR group and 69 were classified to the non-UR group. At the initial stage of rehabilitation, the scores of MMSE, BBS, FAC, MBI were significantly worse in the UR group (p<0.05). Both groups showed significant improvements of all functional outcomes after rehabilitation (p<0.05). The non-UR group showed more prominent recovery of BBS, FAC, MBI scores (p<0.05). CONCLUSION: Urinary retention in post-stroke patients is significantly related to the poor functional status at initial stage of rehabilitation, and also to poor recovery after rehabilitation.

Anorectal Manometric and Urodynamic Parameters According to the Spinal Cord Injury Lesion

OBJECTIVE: To assess the correlation between the anorectal function and bladder detrusor function in patients with complete spinal cord injury (SCI) according to the type of lesion. METHODS: Medical records of twenty-eight patients with SCI were included in this study. We compared the anorectal manometric and urodynamic (UD) parameters in total subjects. We analyzed the anorectal manometric and UD parameters between the two groups: upper motor neuron (UMN) lesion and lower motor neuron (LMN) lesion. In addition, we reclassified the total subjects into two groups according to the bladder detrusor function: overactive and non-overactive. RESULTS: In the group with LMN lesion, the mean value of maximal anal squeeze pressure (MSP) was slightly higher than that in the group with UMN lesion, and the ratio of MSP to maximal anal resting pressure (MRP) was statistically significant different between the two groups. In addition, although the mean value of MSP was slightly higher in the group with non-overactive detrusor function, there was no statistical correlation of anorectal manometric parameters between the groups with overactive and non-overactive detrusor function. CONCLUSION: The MSP and the ratio of MSP to MRP were higher in the group with LMN lesion. In this study, we could not identify the correlation between bladder and bowel function in total subjects. We conclude that the results of UD study alone cannot predict the outcome of anorectal manometry in patients with SCI. Therefore, it is recommended to perform assessment of anorectal function with anorectal manometry in patients with SCI.

Frequency, Intensity and Daily Life Distress of Urinary Dysfunction in Women with Cervical Cancer after Radical Hysterectomy

PURPOSE: This study was done to identify frequency, intensity of urinary dysfunction and daily life distress in women after a radical hysterectomy for cervical cancer. METHODS: One hundred and fifty seven women who had undergone a radical hysterectomy and one hundred and sixty five women as healthy controls completed questionnaires on intensity of urinary dysfunction and daily life distress caused by urinary dysfunction. RESULTS: Women with cervical cancer showed higher frequency of urinary dysfunction than healthy controls. Major urinary dysfunction for women with cervical cancer in order of frequency were night-time incontinence (odds ratio=10.39, p<.001), difficulty in starting urination, weak urine stream and sense of incomplete emptying of bladder. The highest score on intensity was difficulty in starting urination, followed by urgency, weak urine stream, daytime frequency and sense of incomplete emptying. Night-time incontinence was the urinary symptom causing the most daily life distress for cervical cancer women followed by difficulty in starting urination, urgency, sense of incomplete emptying, and night-time frequency. CONCLUSION: Results suggest that nurses should address the potential postoperative urinary complications and develop long term interventions to decrease urinary dysfunction and daily life distress for women who have had a radical hysterectomy for cervical cancer.

The Factors That Affect Improvement of Neurogenic Bladder by Severe Lumbar Disc Herniation in Operation

OBJECTIVE: This study analyzed retrospectively the bladder function of patients after early surgery for cauda equina syndrome (CES) performed within 24 or 48 hours, or after 48 hours of the onset of autonomic symptoms. METHODS: We retrospectively reviewed the clinical data of 31 patients after decompression surgery for lumbar disc herniation (LDH) who had been diagnosed with CES between January 2001 and December 2014 at Inha University Hospital. The following factors were assessed to evaluate the influence of time to surgery: bladder function, rectal incontinence, sexual dysfunction, LDH level, and degree of spinal canal compression. RESULTS: After decompression, the outcome group was categorized into normal bladder function and abnormal bladder function. The patients operated on within 48 hours showed an improved postoperative outcome. Among 16 patients operated on within 48 hours, 13 (81%) recovered normal bladder function. In contrast, among 15 patients with decompression after 48 hours, 6 (40%) recovered normal bladder function. Among 21 patients with mild bladder dysfunction at admission, 16 (76%) recovered normal bladder function after decompression. CONCLUSION: Our study suggests that patients who have decompression surgery within 48 hours of the onset of bladder dysfunction, improve their chances of recovering bladder function than those who have a late operation (>48 hours). Also, patients with mild bladder dysfunction are more likely to recover bladder function after decompression, than patients with severe bladder dysfunction.

URINARY DYSFUNCTION AFTER SURGICAL TREATMENT FOR RECTAL CANCER / Disfunção urinária após tratamento cirúrgico do câncer de reto

BackgroundThe impact on quality of life attributed to treatment for rectal cancer remains high. Deterioration of the urinary function is a relevant complication within that context.ObjectiveTo detect the presence of urinary dysfunction and its risk factors among individuals underwent surgical treatment for rectal cancer.MethodsThe present prospective study analyzed 42 patients from both genders underwent surgical treatment for rectal adenocarcinoma with curative intent. The version of the International Prostatic Symptom Score (IPSS) questionnaire validated for the Portuguese language was applied at two time-points: immediately before and 6 months after surgery. Risk factors for urinary dysfunction were analysed by means of logistic regression and Student’s t-test.ResultsEight (19%) participants exhibited moderate-to-severe urinary dysfunction 6 months after surgery; the average IPSS increased from 1.43 at baseline to 4.62 six months after surgery (P<0.001). None of the variables assessed as potential risk factors exhibited statistical significance, i.e., age, gender, distance from tumour to anal margin, neoadjuvant therapy, adjuvant therapy, type of surgery, surgical approach (laparoscopy or laparotomy), and duration of surgery.ConclusionThis study identified an incidence of 19% of moderate to severe urinary dysfuction after 6 months surveillance. No risk factor for urinary dysfunction was identified in this population.

Neste contexto, a deterioração da função urinária é complicação relevante.ObjetivoIdentificar disfunção urinária e seus fatores de risco em doentes submetidos ao tratamento cirúrgico do câncer de reto.MétodosRealizou-se estudo prospectivo com 42 doentes de ambos os sexos submetidos a tratamento cirúrgico com intenção curativa para adenocarcinoma de reto. Foi utilizado o questionário International Prostatic Symptom Score, validado na língua portuguesa, em dois períodos: imediatamente antes e após 6 meses do procedimento cirúrgico. Os fatores de risco para disfunção urinária foram analisados por regressão logística e teste t de Student.ResultadosApós 6 meses do procedimento cirúrgico, oito (19%) doentes apresentaram disfunção urinária moderada a grave e aumento na média do escore utilizado de 1,43 pontos no pré-operatório para 4,62 pontos no pós-operatório (P<0,001). A análise de fatores de risco para disfunção urinária não mostrou significância para as variáveis estudadas, idade, gênero, distância tumoral da margem anal, neoadjuvância, adjuvância, procedimento cirúrgico realizado, via de acesso cirúrgico (laparoscópica ou laparotômica) e tempo operatório.ConclusãoNos doentes com carcinoma retal operados com intenção curativa, a incidência de disfunção urinária moderada a grave após 6 meses da operação foi de 19%. Não foram identificados fatores de risco para disfunção urinária nesses doentes.

Cateterismo intermitente limpo em crianças com bexiga urinária neurogênica: o cuidado do familiar no domicílio / Clean intermittent catheterization in children with neurogenic urinary bladder: home care by relatives / Cateterismo intermitente limpio en niños con vejiga urinaria neurogénica: el cuidado de la familia en casa

A pesquisa buscou conhecer os cuidados realizados pelo familiar à criança portadora de bexiga neurogênica que necessita de cateterismo vesical intermitente limpo, no domicilio. Trata-se de um estudo qualitativo, realizado em ambulatório de pediatria de um hospital universitário, localizado na cidade do Rio de Janeiro. A coleta dos dados deu-se com 12 familiares através de entrevistas semiestruturadas, no período de janeiro a julho de 2014. Para o tratamento dos dados foi utilizada a análise de conteúdo de Bardin, dando origem a três categorias analíticas: Organizando o ambiente e a criança para o cateterismo; Preparo das mãos para a realização do cateterismo; A realização da técnica pelo familiar. Conclui-se que o cateterismo é realizado conforme a técnica descrita em literatura, mas existem determinados familiares que realizam inadequadamente certos passos da técnica. Sugere-se a realização de protocolos de orientação aos familiares para uniformização de condutas e grupos de apoio aos mesmos.

This qualitative study to examine care provided by family members to children with neurogenic bladder needing clean intermittent catheterization at home was conducted at a pediatric outpatient department of a university hospital in Rio de Janeiro City. Data was collected by semi-structured interviews of 12 family members, between January and July 2014. Data were examined using Bardin content analysis, resulting in three categories: organizing the environment and the child for the catheterization; preparing hands to perform the catheterization; and the technique performed by the family member. It was concluded that catheterization is performed according to the technique described in the literature, but certain family members perform some steps of the technique inappropriately. We suggest producing guidance protocols for family members to standardize conduct, and holding support groups for them.

La recolección de datos se llevó a cabo con 12 familias a través de entrevistas semiestructuradas, en el período de enero a julio de 2014. Para estudio de datos se utilizó el análisis de contenido de Bardin, dando lugar a tres categorías de análisis: La organización del ambiente y del niño al cateterismo; Preparación de las manos para la realización del cateterismo; La realización de la técnica por la familia. Se concluye que el cateterismo se realiza según la técnica descrita en la literatura, pero hay algunos miembros de la familia que realizan inadecuadamente algunos pasos de la técnica. Se sugiere la realización de protocolos de orientación a los familiares con vistas a uniformizar las conductas y grupos de apoyo a los mismos.

Outcomes of Drug-Resistant Urinary Retention in Patients in the Early Stage of Stroke

OBJECTIVE: To investigate the prognosis of patients with stroke and urinary retention resistant to alpha blockers and cholinergic agents. METHODS: Post-void residual urine volume (PVR) was measured in 33 patients with stroke (14 men and 19 women) who were admitted to the department of rehabilitation medicine of our hospital within 30 days after stroke onset. An alpha-blocker and cholinergic agent were administered to patients with PVR >100 mL. If urinary retention had not improved despite the maximum drug doses, the patient was diagnosed with drug-resistant urinary retention. We retrospectively reviewed patient's charts, including PVR at discharge and prognostic factors for PVR. RESULTS: Ten patients (30.3%) could not void or their PVR was >400 mL at discharge (45.7+/-15.4 days after onset) after rehabilitation. Twelve patients (36.4%) could void, and their PVR was 100-400 mL. PVR was consistently <100 mL in 11 patients (33.3%). These measurements correlated with the Korean version of the Modified Barthel Index score, Functional Ambulation Category, and the presence of a communication disorder. CONCLUSION: The results show that 22 patients (66.7%) had incomplete bladder emptying or required catheterization at discharge. Outcomes correlated with functional status, walking ability, and the presence of a communication disorder. Patients with urinary retention and poor general condition require close observation to prevent complications of urinary retention.

Efficacy, Tolerability, and Safety of Oxybutynin Chloride in Pediatric Neurogenic Bladder With Spinal Dysraphism: A Retrospective, Multicenter, Observational Study

PURPOSE: Anticholinergics are a key element in treating neurogenic detrusor overactivity, but only limited data are available in the pediatric population, thus limiting the application to children even for oxybutynin chloride (OC), a prototype drug. This retrospective study was designed to provide data regarding the efficacy, tolerability, and safety of OC in the pediatric population (0-15 years old) with spinal dysraphism (SD). MATERIALS AND METHODS: Records relevant to OC use for neurogenic bladder were gathered and scrutinized from four specialized clinics for pediatric urology. The primary efficacy outcomes were maximal cystometric capacity (MCC) and end filling pressure (EFP). Data on tolerability, compliance, and adverse events (AEs) were also analyzed. RESULTS: Of the 121 patient records analyzed, 41 patients (34%) received OC at less than 5 years of age. The range of prescribed doses varied from 3 to 24 mg/d. The median treatment duration was 19 months (range, 0.3-111 months). Significant improvement of both primary efficacy outcomes was noted following OC treatment. MCC increased about 8% even after adjustment for age-related increases in MCC. Likewise, mean EFP was reduced from 33 to 21 cm H2O. More than 80% of patients showed compliance above 70%, and approximately 50% of patients used OC for more than 1 year. No serious AEs were reported; constipation and facial flushing consisted of the major AEs. CONCLUSIONS: OC is safe and efficacious in treating pediatric neurogenic bladder associated with SD. The drug is also tolerable and the safety profile suggests that adjustment of dosage for age may not be strictly observed.

4-Aminopyridine Improves Lower Urinary Tract Symptoms in a Patient With Benign Prostatic Hyperplasia and Downbeat Nystagmus Syndrome / 대한배뇨장애요실금학회지

Aminopyridines are potassium channel blockers that increase the excitability of nerve cells and axons; therefore, they are widely used to treat different neurological disorders. Here we present a patient with idiopathic downbeat nystagmus and lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia who was treated with the sustained-release form of 4-aminopyridine (4-AP). During treatment with 4-AP, the LUTS improved. This improvement was monitored by using uroflowmetry and the International Prostate Symptom Score. A significant improvement of symptoms was observed in relation to the voided volume. This included an improved emptying of the bladder without an increase in residual urine. In animal studies, both nonselective K+ channel blockade and selective voltage-sensitive potassium blockade by 4-AP resulted in increased contraction on rat detrusor strips. To our knowledge, this is the first clinical observation of the mode of action of 4-AP in urological symptoms in humans.

Intradetrusor Injections of Onabotulinum Toxin-A in Children With Urinary Incontinence due to Neurogenic Detrusor Overactivity Refractory to Antimuscarinic Treatment

PURPOSE: This was a prospective single-arm study to assess the efficacy and safety of intradetrusor injections of onabotulinum toxin-A in children with urinary incontinence associated with neurogenic detrusor overactivity due to myelomeningocele. All patients had failed the first-line treatment of a combination of oral antimuscarinics and intermittent catheterization. MATERIALS AND METHODS: The study group consisted of 31 children with myelomeningocele with a mean age of 7.95 years (range, 5-3 years) who were followed up for a mean of 29 weeks. The amount of onabotulinum toxin A injected was 10 U/kg with a maximal dose of 300 U. There were 20 to 30 injection sites with rigid cystoscopic guidance under general anesthesia. RESULTS: Thirty of 31 patients reported dryness between intermittent catheterization intervals. The mean reduction in maximum detrusor pressure and the mean increase in maximum cystometric capacity from baseline were 53% and 51.5%, respectively, 6 weeks after injection. We found a 324% increase in mean bladder compliance and a 57% increase in mean intermittent catheterization volumes. The mean duration of efficacy was 28 weeks with a single injection and 36 weeks for repeated injections (minimum, 16 weeks; maximum, 52 weeks). The mean time interval between repeated onabotulinum toxin-A injections was 7 months (maximum, 13 months). Intradetrusor injections of onabotulinum toxin-A were well tolerated. CONCLUSIONS: Onabotulinum toxin-A injections into the bladder wall provide a significant symptomatic and urodynamic improvement in children with neurogenic detrusor overactivity due to myelomeningocele who are on intermittent catheterization. The treatment seems to be safe and very well tolerated.

Effects of Bladder Function by Early Tamsulosin Treatment in a Spinal Cord Injury Rat Model

OBJECTIVE: To investigate the effects of early tamsulosin treatment on changes in bladder characteristics after a spinal cord injury. METHODS: We divided 45 rats into three groups: the control (CON) group, the spinal cord injury (SCI) group, and the SCI+tamsulosin treatment (SCI+TAM) group. Spinal cord transection was performed in the SCI and SCI+TAM groups. Tamsulosin was injected for 7 days in the SCI+TAM group. Intravesical and intra-abdominal catheters were implanted before cord injury. Basal pressure (BP), maximal vesical pressure (MVP), micturition volume (MV), and voiding interval time (VIT) were measured at 7 days after SCI. The bladder was then removed and used for an in vitro organ bath study and Western blot analysis. The percentage changes in contractility from baseline after acetylcholine alone, pretreatment with a muscarinic 2 (M2) receptor blocker (AQ-RA741), and pretreatment with a M3 receptor blocker (4-DAMP) were compared among the groups. Western blot analyses were performed to determine expression levels of pERK1/2 and rho-kinase. RESULTS: In cystometry, MVP, BP, MV, and VIT showed changes in the SCI and SCI+TAM groups versus the CON group (p<0.05). In the organ bath study, acetylcholine-induced contractility in the three groups differed significantly (p<0.05). Additionally, acetylcholine-induced contractility with 4-DAMP pretreatment was reduced significantly in the SCI+TAM group versus the SCI group. In Western blotting, pERK1/2 expression was stronger (p<0.05) and rho-kinase expression was weaker in the SCI+TAM group than the SCI group (p<0.05). CONCLUSION: These results suggest that the bladder contraction due to acetylcholine after SCI can be decreased by tamsulosin in the acute stage and this involves changes in pERK1/2 and rho-kinase.

The Association of Lyme Disease With Loss of Sexual Libido and the Role of Urinary Bladder Detrusor Dysfunction / 대한배뇨장애요실금학회지

PURPOSE: The primary aim was to carry out a pilot study to compare the loss of sexual libido between a group of Lyme disease patients and a group of matched controls. The secondary aim was to evaluate whether loss of libido in Lyme disease patients is associated with urinary bladder detrusor dysfunction. METHODS: A group of 16 serologically positive Lyme disease patients and 18 controls were queried directly about loss of libido. RESULTS: The 2 groups were matched with respect to age, sex, body mass index, and mean arterial blood pressure. None of the 34 subjects was taking medication that might affect sexual libido or had undergone a previous operative procedure involving the genitourinary tract. Of the 16 Lyme disease patients, 8 (50%) had no loss of libido, and of the 18 controls, none had loss of libido (P<0.001). In the Lyme disease patient group, there was no statistically significant relationship between loss of libido and urinary bladder detrusor dysfunction (P=0.61). CONCLUSIONS: This pilot study suggested an association between Lyme disease and loss of libido. Moreover, this loss of libido did not seem to be associated with urinary bladder detrusor dysfunction. Given these results, we recommend further studies to confirm the association.
