Validation of the Vancouver Symptom Score Questionnaire for bladder and bowel dysfunction for Brazilian children and adolescents

ABSTRACT Objective: This study aimed to translate, and perform a cross-cultural adaptation, and validation of the Vancouver Symptom Score (VSS) for bladder and bowel dysfunction (BBD) for Brazilian children and adolescents Materials and Methods: Six steps were performed for the translation and cross-cultural adaptation: (1) translation, (2) synthesis of translations, (3) back-translation, (4) pre-final version of the translated instrument, (5) pilot test and degree of comprehensibility and (6) elaboration of the Brazilian version of the VSS. For validation, the Brazilian Dysfunctional Voiding Score (DVSS) questionnaire was used. Results: Validation was performed on a sample of 107 children and adolescents with a mean age of 9.2 ± 2.84 years, presenting BBD and 107 without BBD (control group-CG). There was a positive correlation (r = 0.91, 95% CI 0.88 to 0.93, p < 0.0001) between total VSS score and total DVSS score. VSS was higher in patients with BBD (p < 0.0001). The internal consistency estimated by Cronbach's alpha was 0.87 for patients with BBD. The VSS showed excellent diagnostic accuracy in detecting cases, with an area under the ROC curve of 98% (95% CI 0.96 to 0.99, p < 0.001). A cut-off value of >11 points produced a sensitivity of 100% (95% CI 96.4% to 100%) and a specificity of 91.8% (95% CI 85.1% to 95.6%). Conclusion: The translated, cross-culturally adapted, and validated VSS for the Brazilian population is a reliable and valid tool to identify symptoms of BBD in children and adolescents aged five to 16 years, whose first language is Brazilian Portuguese.

Changes of bladder morphology and function and effect on upper urinary tract dilatation at different time after lumbosacral nerve transecting in rats / 中华泌尿外科杂志

Objective:To investigate the changes in the morphology, structure and function of the bladders and their effects on the upper urinary tract dilatation(UUTD) after lumbosacral nerve transecting in rats.Methods:A total of 45 female SD rats were included, randomly divided into 3 groups with 15 rats in each group. Two groups were performed bilateral lumbar 6(L6) and cauda equina nerve shearing to establish neurogenic bladder(NB) model, which were nerve transected for 4 weeks(NB-4W) group and nerve transected for 12 weeks(NB-12W) group. Another group was performed bilateral L6 nerves and cauda equine exposing but not transecting, which was sham-operation (Sham) group. Cystometry and renal ultrasound examination were performed and rats in each group were killed to collect the kidney and bladder tissues in NB-4W group at 4 weeks, in Sham group and NB-12W group at 12 weeks after operation. HE, Masson staining, immunohistochemical staining and western blot were used to detect histological changes, expression of transforming growth factor-β1(TGF-β1) and α-smooth muscle actin(α-SMA).Results:All rats in NB-4W and NB-12W group showed acontractile detrusor. In the NB-4W and NB-12W group, the maximum cystometric capacity [(5.84±0.33) ml and (3.13±0.35) ml], the detrusor leak point pressure [(25.41±0.86) cm H 2O and (27.36±2.04) cm H 2O] (1 cm H 2O = 0.098 kPa), were significantly higher than those in the Sham group [(0.98±0.14) ml, (7.13±0.90) cm H 2O, both P<0.05]. Compliance in NB-4W group [(0.28±0.21) ml/cm H 2O] and NB-12W group [(0.17±0.12) ml/cm H 2O] were significantly lower than that of the Sham group [(0.34±0.26) ml/cm H 2O], and the compliance of NB-12W group was lower than that of NB-4W group significantly (all P<0.05). HE staining of the bladder showed that the inflammatory cell infiltration was obvious in the NB-4W and NB-12W group. Bladder collagen volume fractions in NB-4W group [(30.5±1.5) %] and NB-12W group [(45.2±3.8) %] were both higher than that of Sham group [(20.7±2.2) %, both P<0.05]. The expression of TGF-β1 and α-SMA in the bladder tissue of NB-4W group were higher than those of sham group, and that of NB-12W group were higher than NB-4W group. In NB-4W group and NB-12W group, 3 (20.0 %) and 7 (46.7 %) rats were found hydronephrosis, respectively. Additionally, HE staining showed that the degree of renal tubule injury and the number of inflammatory cell infiltration in the NB-4W and NB-12W group were higher than those in the Sham group. Masson staining showed that the volume fraction of collagen in kidneys of NB-4W and NB-12W group were (13.1±1.4) % and (21.6±1.9) %, respectively, which were significantly higher than that in sham operation group [(4.6±0.7) %, both P<0.05]. Conclusions:Bilateral L6 + cauda equina nerve transecting can induce NB with hydronephrosis in parts of rats. The degree of bladder fibrosis gradually increased with the time of nerve transection, and the incidence and severity of UUTD also increased with the time of nerve transection.

Comparison of urodynamic changes in elderly patients with central neurogenic bladder and with peripheral neurogenic bladder / 中华老年医学杂志

Objective:To examine differences in urodynamic changes between central neurogenic bladder(CNB)and peripheral neurogenic bladder(PNB)in elderly patients.Methods:A total of 57 elderly patients over 60 years old with neurogenic bladder(NB)were divided into a CNB group and a PNB group based on the types of nerve injuries.Data on urodynamic parameters recorded for the two groups were compared and analyzed.Results:The rate of detrusor overactivity(DO)in the CNB group was significantly higher than that in the PNB group [66.7%(16/24)vs.36.4%(12/33), χ2=5.105, P=0.024]. There were significant differences between the two groups in maximum bladder capacity(MCC)[(277.8±101.1)in the CNB group vs.(481.4±110.2)ml in the PNB group, t=-7.149, P=0.001]and in safe bladder capacity(SBC)[(283.2±28.8)ml in the CNB group vs.(348.6±33.9)ml in the PNB group, t=-7.636, P=0.000]. There was no significant difference between the two groups in the maximum urine flow rate, residual urine volume, urination volume, leak point pressure, or detrusor pressure at the maximum urine flow rate(all P>0.05). In the CNB group, 8 patients had normal bladder sensation, 4 had disappeared bladder sensation, 10 had decreased sensation, and 2 had increased sensation.In the PNB group, 9 patients had normal bladder sensation, 4 had disappeared bladder sensation, 14 had decreased sensation, and 2 had increased sensation.There was no statistical significance in SBC between different sensation levels within each group( P>0.05). Conclusions:There are differences in urodynamic characteristics between the elderly patients with CNB and those with PNB.Decreases in MCC, SBC and DO are more likely to occur in CNB.

In utero myelomeningocele repair and high-risk bladder pattern. a prospective study

ABSTRACT Objectives High-risk bladder pattern can be defined by Urodynamic Evaluation (UE) as overactive bladder with detrusor leak point pressure higher than 40 cmH2O and/or higher filling pressures also above 40 cmH2O. We wanted to evaluate response to treatment in myelomeningocele patients operated in utero in this subgroup. Patients and Methods From our prospective cohort of in utero MMC we have identified patients in the high-risk group. Treatment consisted of anticholinergics (Oxybutynin 0.2 mg/Kg) 2 or 3 times daily in association with CIC. At every UE, patients were reclassified in high-risk or low-risk patterns. Patients not responding were proposed bladder reconstruction or diversion according to age. Results Between 2011 to 2020, we have been following 121 patients and 60 (49.6%) of them were initially categorized as high-risk. The initial UE was performed at a mean age of 7.9 months and detrusor overactivity was found in 83.3% (mean maximum pressure of 76.5cmH20). When evaluating patients with 2 or more UE, we identified 44 patients (follow-up: 36.8months). It was observed in the group of patients who underwent 2 to 5 UE, that response to treatment was validated by the finding of 40% of low-risk bladder patterns in the second UE and between 62% to 64% in the third to the fifth UE. The incidence of surgery was 13.3%. Conclusions Early urological treatment of high-risk bladder pattern was effective in approximately 60%. We reinforce the need to correctly treat every patient with myelomeningocele, in accordance with UE, whether undergoing in utero or postnatal treatment.

Could urinary nerve growth factor and bladder wall thickness predict the treatment outcome of children with overactive bladder?

ABSTRACT Objective: Bladder wall thickness (BWTh) measurements and Nerve Growth Factor (NGF) /creatinine (Cr) values, as noninvasive tools, were found to predict daytime voiding problems in children with overactive bladder (OAB). The goal of this research was to examine if bladder wall thickness together with urine NGF/Cr could be a clinical utility in treatment outcome of OAB in children. Patients and Methods: A total of 60 children with OAB, (Group 1; n=40) and healthy normal controls (Group 2; n=20), aged 6-14 years old were involved in this prospective study. Children were evaluated with detailed history and physical examination, including neurologic examination, and were asked to complete a self-reported questionnaire and a 3-day bladder diary with the aid of their parents. Uroflowmetry was performed in all cases. Urinary nerve growth factor levels were measured by the ELISA and BWTh was measured trans-abdominally by one uro-radiologist specialized in pediatric ultrasonography. Urinary NGF levels were normalized by urinary creatinine levels and compared among all subgroups. Children with OAB received urotherapy as first line treatment at least for three months. 18 children refractory to urotherapy received anticholinergic therapy defined as group 3. Results: The median age of the study group was 10 (range 6 to 16). After urotherapy, 22 children had similar BWTh and NGF/Cr values compared to controls. (2.75 ± 1.15; 2.40 ± 1.00 mm; p=0.86 and 1.02 ± 0.10; 0.78 ± 0.15; p=0.12, respectively). After anticholinergic treatment, BWTh levels (2.25 ± 0.90; 2.40 ± 1.00 mm; p=0.94) and NGF/Cr values (0.95 ± 0.10; 0.78 ± 0.15; p=0.42, respectively) had no significantly difference compared to controls (Group 2). In receiver operating characteristic analysis, bladder wall thickness was found to have sensitivity of 85% and specificity of 84.2% (3,20 AUC, 913; 95 %) and NGF/Cr had sensitivity of 90% and specificity of 92.1% (1,595; AUC, 947; 95 %) in predicting treatment outcome in children with OAB. Conclusions: Bladder wall thickness measurements and NGF/Cr values, as noninvasive tools, could guide outcomes in the treatment of children with overactive bladder.

Can concomitant bladder neck incision and primary valve ablation reduce early re-admission rate and secondary intervention?

ABSTRACT Objective: To assess the effect of bladder neck morphology and its incision (BNI) in patients with posterior urethral valve (PUV) on early reintervention rate. Patients and methods: Infants undergoing PUV ablation (PVA) before 24 months of age and had at least 18 months of follow-up, were categorized into three groups according to the bladder neck appearance on baseline radiological and endoscopic examination: group 1; normal bladder neck underwent PVA, group 2; high bladder neck underwent PVA plus BNI, group 3; high bladder neck underwent PVA only. Early reintervention was defined as the need for check cystoscopy because of persistent renal function deterioration, worsening hydronephrosis and/or unsatisfactory VCUG improvement during the 1st six months post primary PVA. Results: Between 2000 and 2017, a total of 114 patients underwent PVA and met the study criteria with a median follow-up of 58 (18-230) months. For group 1, 16 (22.9%) patients needed readmission. Check cystoscopy was free and no further intervention was performed in 5(7.5%) and re-ablation was performed in 11(15.7%) patients. For group 2, 3(14.3%) patients needed reintervention. Re-ablation and re-ablation plus BNI were performed in 1(4.8%) and 2(9.5%), respectively. For group 3, cystoscopy was free in 1(4.3%), re-ablation and re-ablation plus BNI were performed 2(8.7%) and 1(4.3%), respectively. There were no significant differences in the re-admission and re-intervention rates among the three study groups (p=0.65 and p=0.50, respectively). Conclusion: In morphologically high bladder neck associated PUV, concomitant BNI with PVA doesn't reduce early re-intervention rate.

Management of neurogenic bladder dysfunction in children update and recommendations on medical treatment

ABSTRACT Introduction: Defective closure of the neural tube affects different systems and generates sequelae, such as neurogenic bladder (NB). Myelomeningocele (MMC) represents the most frequent and most severe cause of NB in children. Damage of the renal parenchyma in children with NB acquired in postnatal stages is preventable given adequate evaluation, follow-up and proactive management. The aim of this document is to update issues on medical management of neurogenic bladder in children. Materials and Methods: Five Pediatric Urologists joined a group of experts and reviewed all important issues on "Spina Bifida, Neurogenic Bladder in Children" and elaborated a draft of the document. All the members of the group focused on the same system of classification of the levels of evidence (GRADE system) in order to assess the literature and the recommendations. During the year 2020 the panel of experts has met virtually to review, discuss and write a consensus document. Results and Discussion: The panel addressed recommendations on up to date choice of diagnosis evaluation and therapies. Clean intermittent catheterization (CIC) should be implemented during the first days of life, and antimuscarinic drugs should be indicated upon results of urodynamic studies. When the patient becomes refractory to first-line therapy, receptor-selective pharmacotherapy is available nowadays, which leads to a reduction in reconstructive procedures, such as augmentation cystoplasty.

Self-perception, quality of life and ease of catheterization in patients with continent urinary diversion with the mitrofanoff principle

ABSTRACT Purpose: Continent urinary diversion (CUD) with the Mitrofanoff principle stands as an alternative to urethral catheterization by a route other than the urethra. The aim of the study was to determine self-perception of health-related quality of life (HRQoL), ease of catheterization and global and cosmetic outcomes in patient's dependent on Mitrofanoff catheterization. Materials and methods: Records of all patients who underwent CUD with the Mitrofanoff principle between 2012 to 2018 were reviewed. Data were collected and analysed retrospectively from medical charts. We assessed HRQoL with the EuroQol EQ-5D-3L questionnaire, cosmetic and global satisfaction with a questionnaire designed by the reconstructive urology board and ease of catheterization with a Likert questionnaire adapted from the Intermittent Catheterization Difficulty Questionnaire (ICDQ) validated in patients reliant on retrograde CIC. Results: A total of 25 patients requiring CUD with the Mitrofanoff principle between 2012 and 2018 were assessed, the group was composed mainly of: appendiceal conduits 18 patients (72%) and 7 ileal conduits (Yang-Monti) and three of those requiring Casale (Monti Spiral) and 1 a double Monti technique. Median follow-up was 57 months, median age was 30 years. Visual Analogue Scale (VAS) of the EQ-5D-3L reported a Global health score of 86.5%. Fifty nine percent of the patients had no pain or bleeding with catheterizations. Regarding global satisfaction and cosmetic perception 91% were satisfied with their CUD. Conclusions: CUD is associated with good HRQoL, global satisfaction, ease and painless catheterization, adequate self-perception of cosmetic outcomes and a low complication rate, remaining a safe and viable option.

Association between stress and lower urinary tract symptoms in children and adolescents

ABSTRACT Introduction: Lower urinary tract dysfunction (LUTD) is a common clinical condition. Emotional and behavioral issues are increasing among children and adolescents, with stress indicating difficulties in personal and social functioning. This study evaluated whether urinary tract symptoms (LUTS) is associated with stress. Materials and Methods: A cross-sectional, analytical study with 6-14-year-old patients with LUTS and no anatomical/neurogenic urinary tract abnormalities was conducted using the Dysfunctional Voiding Scoring System, a psychological assessment and the Child Stress Scale. The overall stress score was analyzed in relation to the psychological assessment data. Answers to the seven specific DVSS urinary questions were compared with those for the four Child Stress Scale domains. Univariate and multivariate analyses were performed. The chi-square test and Pearson's correlation were used to determine associations. Significance was defined as p <0.05. Results: Most children were male (56%). Mean age was 9.0±2.25 years. Stress was detected in 20 out of 98 patients (20.4%; 95% CI: 13-30%). Of these, 90% were born from unplanned pregnancies and 67% were upset about their disorder. All the Child Stress Scale domains were significantly associated with urinary dysfunction, with dysuria being significantly associated with all four domains. In the multivariate analysis, dysuria was the only symptom that remained associated with stress. Associations with stress strengthened as the frequency of dysuria increased: physical reactions (p <0.01), emotional reactions (p <0.05), psychological reactions with a depressive component (p <0.01) and psychophysiological reactions (p <0.05). Conclusion: Stress levels are higher in children and adolescents with LUTS who have more severe symptoms. Dysuria was the symptom most associated with stress, both in the physical reactions domain, in the psychological reactions domains with or without a depressive component and in the psychophysiological reactions domain.

Trends in renal calculus composition and 24-hour urine analyses in patients with neurologically derived musculoskeletal deficiencies

ABSTRACT Purpose: To better characterize metabolic stone risk in patients with neurologically derived musculoskeletal deficiencies (NDMD) by determining how patient characteristics relate to renal calculus composition and 24-hour urine parameters. Materials and Methods: We performed a retrospective cohort study of adult patients with neurologically derived musculoskeletal deficiencies presenting to our multidisciplinary Kidney Stone Clinic. Patients with a diagnosis of NDMD, at least one 24-hour urine collection, and one chemical stone analysis were included in the analysis. Calculi were classified as primarily metabolic or elevated pH. We assessed in clinical factors, demographics, and urine metabolites for differences between patients who formed primarily metabolic or elevated pH stones. Results: Over a 16-year period, 100 patients with NDMD and nephrolithiasis were identified and 41 met inclusion criteria. Thirty percent (12 / 41) of patients had purely metabolic calculi. Patients with metabolic calculi were significantly more likely to be obese (median body mass index 30.3kg / m2 versus 25.9kg / m2), void spontaneously (75% vs. 6.9%), and have low urine volumes (100% vs. 69%). Patients who formed elevated pH stones were more likely to have positive preoperative urine cultures with urease splitting organisms (58.6% vs. 16.7%) and be hyperoxaluric and hypocitraturic on 24-hour urine analysis (37mg / day and 265mg / day versus 29mg / day and 523mg / day). Conclusions: Among patients with NDMD, metabolic factors may play a more significant role in renal calculus formation than previously believed. There is still a high incidence of carbonate apatite calculi, which could be attributed to bacteriuria. However, obesity, low urine volumes, hypocitraturia, and hyperoxaluria suggest an underrecognized metabolic contribution to stone formation in this population.

Neuromodulação não invasiva em crianças com Bexiga Neurogênica: uma revisão integrativa / Non-invasive neuromodulation in children with Neurogenic Bladder: an integrative review

INTRODUÇÃO: O tratamento da Bexiga Neurogênica (BN) pode ser feito através do manejo farmacológico e/ou não farmacológico. Dentro do tratamento não farmacológico temos a neuromodulação não invasiva (NMNI) realizada com aplicação de eletrodos transcutâneos que sugere uma modulação nos componentes excitatórios e inibitórios do controle da bexiga. OBJETIVO: Reunir evidencias que avaliem o efeito da NMNI na BN de crianças com disfunções neurológicas. MÉTODOS: Trata-se de um artigo de revisão integrativa que foi elaborada seguindo sete etapas. A busca foi feita nas bases de dados PubMed, Biblioteca Virtual de Saúde (BVS) e ScienceDirect. A escolha dos artigos foi realizada inicialmente por dois avaliadores independentes, obedecendo os critérios de elegibilidade: realizar tratamento para BN utilizando estimulação elétrica não invasiva com objetivo de neuromodulação da via urinária; população amostral composta por crianças com alteração miccional em decorrência de alguma disfunção neurológica e possuir os textos disponíveis na íntegra nas plataformas online de busca, no período de Agosto a Novembro de 2018. Foram incluídos artigos que utilizaram NMNI como tratamento da BN em crianças. RESULTADOS: Foram encontrados 440 artigos e apenas 5 atenderam aos critérios de inclusão. Ao todo, participaram dos estudos 141 crianças com acometimentos neurológicos. Os principais elementos utilizados nas avaliações foram diário miccional, o estudo urodinâmico, a coleta da história clínica e o exame físico. Os parâmetros de estimulação e posicionamento de eletrodos foram variados. CONCLUSÃO: A NMNI apresentou bons resultados no tratamento de crianças com BN e, foi observado também, efeitos positivos no intestino neurogênico, porém, são necessários mais estudos que sugiram protocolos bem delineados para a reprodução na prática clínica.

INTRODUCTION: The treatment of Neurogenic Bladder (NB) may be performed through pharmacological and/or nonpharmacological techniques. In relation to the non-pharmacological treatment, non-invasive neuromodulation (NINM) is widely used applying transcutaneous electrodes, which suggest a modulation on the excitatory components and bladder control inhibitors. OBJECTIVE: To gather evidence in order to assess the effect of NINM on the NB of children with neurological dysfunctions. METHODS: It is an integrative review article elaborated following seven steps. The research was done in the databases PubMed, Virtual Health Library (VHL) and ScienceDirect. Assortment of articles was initially made by two independent evaluators, obeying the eligibility criteria: perform NB treatment using noninvasive electrical stimulation aiming urinary tract neuromodulation; population sample composed by children with voiding alteration due to a neurological dysfunction and which have full texts available, from August to November 2018. Were included articles which used NINM as a treatment of NB in children. RESULTS: 440 articles were found, however only five met the inclusion criteria. Overall, 141 children with neurological afflictions were part of the study. The main evaluators elements were the voiding diary, the urodynamic study, collection of clinical history and physical exam. Parameters of stimulation and position of the electrodes varied between the studies. CONCLUSION: NINM showed agreable results in the treatment of children with NB, In addition, positive effects were observed in relation to the neurogenic intestine, despite the needing of further studies which suggest well-designed protocols for reproduction in clinical practice.

PURPOSE: We retrospectively evaluated the efficacy of botulinum neurotoxin A (BoNT-A) on vesicoureteral reflux (VUR), continence status, and urodynamic parameters in children with myelodysplasia who were not responsive to standard conservative therapy.METHODS: The study included 31 children (13 boys, 18 girls) with a mean age of 9.2±2.3 years (range, 5–14 years) with myelodysplasia, retrospectively. All children were fully compatible with clean intermittent catheterization (CIC) and did not respond to the maximum tolerable anticholinergic dose. All children received an intradetrusor injection of 10 U/kg (maximum, 300 U) of BoNT-A into an infection-free bladder. All patients had VUR (22 unilateral, 9 bilateral) preoperatively. The grade of reflux was mild (grades 1, 2), intermediate (grade 3), and severe (grades 4, 5) in 25, 7, and 8 ureters, respectively.RESULTS: The mean maximum bladder capacity increased from 152.9±76.9 mL to 243.7±103 mL (P<0.001), and the maximum detrusor pressure decreased from 57±29.4 cm H₂O to 29.6±13.9 cm H₂O (P<0.001). After BoNT-A treatment, 16 refluxing ureters (40%) completely resolved, 17 (42.5%) improved, 5 (12.5%) remained unchanged, and 2 (5%) became worse. Of the 31 children with urinary leakage between CICs, 22 (71%) became completely dry, 6 (19%) improved, and 3 (10%) experienced partial improvement.CONCLUSIONS: In children with myelodysplasia, we were able to increase bladder capacity, enhance continence, and prevent VUR by using intradetrusor BoNT-A injections. Although our results are promising, a larger group of long-term prospective studies are warranted to investigate this method of treatment.

Are uroflowmetry and post - void residual urine tests necessary in children with primary nocturnal enuresis?

ABSTRACT Objectives: To examine the benefits of repetitive uroflowmetry and post void residual urine (PVR) tests in children with primary nocturnal enuresis (PNE). Material and methods: Children aged ≥6 years with PNE who visited our clinics for management of enuresis were included for study. Patients were requested to complete a questionnaire including baseline characteristics and Dysfunctional Voiding Symptom Score (DVSS), 2-day bladder diary, and Rome III criteria for constipation. Two uroflowmetry and PVR tests were requested. Children with congenital or neurogenic genitourinary tract disorders were excluded. All children underwent urotherapy and desmopressin combined with anticholinergics or laxatives if indicated. The definition of abnormal flow patterns (≥1 abnormal), elevated PVR (≥1 abnormal), small maximal voided volume (MVV), nocturnal polyuria (NP) and response to treatment complied with the ICCS standardization document. Kaplan-Meier survival analysis and Cox proportional-hazards regression tests were used to evaluate the predictors of response. Results: In total, 100 children aged 8.5±2.3 years were enrolled for study (M: F=66:34) with 7.3±7.4 months of follow-up. Poor correlation was observed between DVSS/small MVV and PVR (p>0.05). Univariate analysis revealed that elevated PVR is associated with significantly less hazard of complete response to medical treatment (HR: 0.52, p=0.03), while not significantly associated with abnormal flow patterns, NP, constipation or small MVV. Multivariate analysis revealed that only elevated PVR (HR 0.30, 95% CI 0.12-0.80) and NP (HR 2.8, 95% CI 1.10-7.28) were significant predictors for complete response. Conclusions: In managing pediatric enuresis, elevated PVR is a significant predictor for lower chance of complete response to treatment whether they had high DVSS or not.

Intradetrusor onabotulinumtoxinA injections are significantly more efficacious than oral oxybutynin for treatment of neurogenic detrusor overactivity: results of a randomized, controlled, 24-week trial / Injeções intradetrusoras de onabotulinumtoxinA são significativamente mais eficazes que oxibutinina oral para tratamento da hiperatividade detrusora neurogênica: resultados de estudo randomizado e controlado de 24 semanas

ABSTRACT Objective To prospectively compare the results of intradetrusor onabotulinumtoxinA injections and oral oxybutynin for urinary continence, urodynamic parameters and quality of life in patients with neurogenic detrusor overactivity due to spinal cord injury. Methods Adult patients under intermittent catheterization were randomized 1:1 to receive one injection of onabotulinumtoxinA 300U or oxybutynin 5mg, per oris, three times/day. Primary study endpoint was change in urinary incontinence episodes/24 hours and secondary study endpoints were maximum cystometric capacity, maximum detrusor pressure, bladder compliance and quality of life before randomization and at week 24. Results Sixty-eight patients participated in the trial. Significant improvements in urinary incontinence per 24 hours, all investigated urodynamic parameters and quality of life were observed in both groups. Compared with oral oxybutynin, onabotulinumtoxinA was significantly more efficacious for all parameters investigated. Non-response to treatment was higher for oral oxybutynin (23.5%) than onabotulinumtoxinA (11.8%). Dry mouth was the most common adverse in patients with oral oxybutynin (72%) and transient macroscopic hematuria in patients with onabotulinumtoxinA (28%). Only one patient with oral oxybutynin dropped out the study because of adverse effects. Conclusion The comparison of the two study drugs showed that onabotulinumtoxinA was significantly more efficacious than oral oxybutynin with regard to continence, urodynamic parameters and quality of life. Clinicaltrials.gov: NCT:01477736.

RESUMO Objetivo Comparar prospectivamente os resultados de injeções intradetrusoras de onabotulinumtoxinA e oxibutinina oral em pacientes com hiperatividade neurogênica do detrusor devido à lesão da medula espinhal, para avaliar a continência urinária, os parâmetros urodinâmicos e a qualidade de vida. Métodos Pacientes adultos em cateterismo intermitente foram randomizados 1:1 para tratamento com uma injeção de onabotulinumtoxinA 300U ou oxibutinina 5mg via oral, três vezes por dia. O desfecho primário foi alteração nos episódios de incontinência urinária em 24 horas, e os secundários foram capacidade cistométrica máxima, pressão máxima do detrusor, complacência vesical e qualidade de vida antes da randomização e na 24ª semana. Resultados Participaram do estudo 68 pacientes. Observou-se melhora significativa na incontinência urinária por 24 horas em todos os parâmetros urodinâmicos investigados e na qualidade de vida em ambos os grupos. Em comparação com a oxibutinina oral, a onabotulinumtoxinA foi significativamente mais eficaz para todos os parâmetros investigados. A falha no tratamento foi maior para oxibutinina oral (23,5%) em comparação com onabotulinumtoxinA (11,8%). A boca seca foi o evento adverso mais comum em pacientes tratados com oxibutinina oral (72%), e a hematúria macroscópica transitória naqueles tratados com onabotulinumtoxinA (28%). Apenas um paciente tratado com oxibutinina oral interrompeu o estudo por conta dos efeitos adversos. Conclusão A comparação dos dois fármacos do estudo mostrou que onabotulinumtoxinA foi significativamente mais eficaz que oxibutinina oral em relação a continência, parâmetros urodinâmicos e qualidade de vida. Clinicaltrials.gov: NCT:01477736.

Long-term response of different Botulinum toxins in refractory neurogenic detrusor overactivity due to spinal cord injury

ABSTRACT Purpose To assess the response in spinal cord injured patients alternatively treated with different types and dosages of Botulinum neurotoxin type A (BoNT/A) over 15 years. Material and methods Patients who underwent first BoNT/A from 1999-2001 and practiced intermittent catheterization were included. Baseline 3-day bladder diary (BD) and urodynamics were collected. BoNT/A failure was defined when patients asked for re-injection ≤ 3 months post-treatment. Criteria for re-injection was at least one daily episode of urinary incontinence at BD. Before re-injection, patients were asked if they had reached 6 months of dryness without antimuscarinics (YES response). Results Overall, 32/60 (53.4%) "No failure" (NF) group; 16 (26.6%) "occasional failure" (OF) and 12 (20%) "consecutive failure" (CF) were included. A total of 822 BoNT/A infiltrations were performed. The mean interval from previous injection to treatment re-scheduling was 8 months. No significant differences between treatments were found within the three groups (p>0.05). The percentage of YES responses increased from 19% (AboBoNT/A 500IU) to 29 % (OnaBoNT/A 300IU) in NF, and from 18% (AboBoNT/A 500IU) to 25% (OnaBoNT/A 300IU) for OF. Five NF cases (15.6%) maintained 6 months of dryness after each injection. Among the baseline variables, only low compliance (< 20mL/cmH2O) was found as predictor for failure (p=0.006). Conclusions Long term BoNT/A for NDO did not increase failures, independent of the types of treatments and switching. Definition of failure and other criteria for continuing repetitive BoNT/A treatment is mandatory. CF was predictable for no response in earlier follow-up.

Recent advances in the treatment of neurogenic bladder in children / 中国医师杂志

Neurogenic bladder is a class of diseases in the damage of normal urine and storage function that are resulted from any cause of central or peripheral nerve damage,which is also called neurogenic bladder dysfunction (neuropathic bladder dysfunction,NBSD).Children~ neurogenic bladder is a common cause of congenital spinal cord dysplasia with high morbidity,and progressive development can cause the urine impaired even life-threatening.The treatment of neurogenic bladder cannot obtain satisfactory results yet.This review summarizes the recent advances in the treatment of neurogenic bladder.
