OBJECTIVE: To compare the effectiveness of tibial nerve transcutaneous electrical nerve stimulation (TENS) for an overactive bladder, considering the sites of application and frequency of attendance. METHODS: This multi-arm randomized controlled trial enrolled 137 adult women (61.0±9.0 years) with overactive bladder from a university hospital. They underwent 12 sessions of 30-min TENS application and were assigned to five groups: one leg, once a week (n=26); one leg, twice a week (n=27); two legs, once a week (n=26); two legs, twice a week (n=28); and placebo (n=30). Symptoms of overactive bladder and its impact on quality of life were evaluated before and after 6 or 12 weeks of treatment using the Overactive Bladder Questionnaire-V8 and voiding diary. ClinicalTrials.gov: NCT01912885. RESULTS: The use of one leg, once a week TENS application reduced the frequency of urgency episodes compared with the placebo (1.0±1.6 vs. 1.4±1.9; p=0.046) and frequency of incontinence episodes compared with the placebo (0.7±1.4 vs.1.4±2.2; p<0.0001). The one-leg, twice a week protocol decreased the urinary frequency compared with the two legs, once a week protocol (8.2±3.5 vs. 9.0±5.1; p=0.026) and placebo (8.2±3.5 vs. 7.9±2.7; p=0.02). Nocturia improved using the two legs, once a week protocol (1.5±1.8) when compared with the one leg, twice a week protocol (1.9±2.0) and placebo (1.7±1.6) (p=0.005 and p=0.027, respectively). Nocturia also improved using the two legs, twice a week protocol when compared with the one leg, twice a week protocol (1.3±1.2 vs.1.9±2.0; p=0.011). CONCLUSION: One-leg stimulation improved the daily urinary frequency, urgency, and incontinence, and the two-leg stimulation once and twice weekly improved nocturia.

Resumo Objetivo: Avaliar se a realização de procedimentos anti-incontinência durante a correção cirúrgica do prolapso anterior e/ou apical em mulheres assintomáticas para incontinência urinária (IU) pode prevenir a incontinência urinária de esforço (IUE) no pós-operatório. Métodos: Foi realizada uma revisão sistemática dos artigos publicados nas bases de dados PubMed, Cochrane Library e Lilacs até o dia 31 de março de 2016. Dois revisores realizaram a coleta e a análise de dados, de forma independente. Todos os estudos selecionados foram analisados metodologicamente. Os resultados estão apresentados como risco relativo (RR), com 95% de intervalo de confiança (IC). Resultados: Após a seleção do estudo, apenas nove estudos preencheram os prérequisitos necessários. Nesta revisão, 1.146 pacientes foram incluídos. No total, a revisão incluiu ensaios de três tipos diferentes de procedimentos anti-incontinência. Descobrimos que realizar qualquer procedimento anti-incontinência ao mesmo tempo que o reparo do prolapso reduziu a incidência de IU no pós-operatório (RR = 0,50; IC 95%: 0,28-0,91). No entanto, quando fizemos a análise separadamente pelo tipo de procedimento antiincontinência, encontramos resultados diferentes. Na análise de subgrupos com slings miduretrais, é benéfico realizá-lo para reduzir a incidência de IU (RR = 0,08; IC 95%: 0,02- 0,28). Por outro lado, na análise de subgrupo com colposuspensão de Burch, não houve diferença significativa com o grupo controle (RR = 1,47; IC 95%: 0,28-7,79]). Conclusão: A realização de qualquer procedimento profilático anti-incontinência ao mesmo tempo que o reparo do prolapso reduziu a incidência de IUE no pós-operatório. A colposuspensão de Burch nãomostrou diminuição na incidência de IUE no pós-operatório.

Abstract Objective To evaluate if performing anti-incontinence procedures during surgical anterior and/or apical prolapse correction in women with asymptomatic urinary incontinence (UI) may prevent stress urinary incontinence (SUI) postoperatively. Methods We have performed a systematic review of articles published in the PubMed, Cochrane Library, and Lilacs databases until March 31, 2016. Two reviewers performed the data collection and analysis, independently. All of the selected studiesweremethodologically analyzed. The results are presented as relative risk (RR), with a 95% confidence interval (CI). Results After performing the selection of the studies, only nine trials fulfilled the necessary prerequisites. In the present review, 1,146 patients were included. Altogether, the review included trials of three different types of anti-incontinence procedures. We found that performing any anti-incontinence procedure at the same time of prolapse repair reduced the incidence of SUI postoperatively (RR = 0.50; 95% CI: 0.28-0.91). However, when we performed the analysis separately by the type of anti-incontinence procedure, we found different results. In the subgroup analysis with midurethral slings, it is beneficial to perform it to reduce the incidence of SUI (RR = 0.08; 95% CI: 0.02-0.28). On the other hand, in the subgroup analysis with Burch colposuspension, there was no significant difference with the control group (RR = 1.47; 95% CI: 0.28-7.79]). Conclusion Performing any prophylactic anti-incontinence procedure at the same time as prolapse repair reduced the incidence of SUI postoperatively. The Burch colposuspension did not show any decrease in the incidence of SUI postoperatively.

Resumo Objetivo comparar tratamentos cirúrgicos para incontinência urinária de esforço (IUE), quanto à eficiência e complicações, por meio de revisão sistemática seguida de metanálise. Fonte dos dados Fizemos busca nas bases de dados MEDLINE e COCHRANE, utilizando os termos stress urinary incontinence, surgical treatment for stress urinary incontinence e sling. Seleção dos estudos Selecionamos 48 estudos, totalizando 6.881 pacientes com pontuação igual ou maior do que 3 na escala de Jadad. Coleta de dados Cada estudo foi lido por um autor, colocado em tabela, e checado por outro autor. Extraímos dados como detalhes das intervenções, tempo de seguimento, resultados do tratamento e eventos adversos. Síntese dos dados Não houve diferença nas comparações: sling de uretra média versus cirurgia de Burch, quanto às curas objetiva (razão de chances [RC]: 1,29; intervalo de confiança de 95% [IC95%]: 0,76-2,20) e subjetiva (RC: 1,16; IC95%: 0,67- 2,00); sling de uretramédia transobturatório outside-in versus inside-out quanto às curas objetiva (RC: 0,78; IC95%: 0,45-1,35) e subjetiva (RC: 0,83; IC95%: 0,58-1,18); sling pubovaginal e de uretra média quanto à cura objetiva (RC: 1,64; IC 95%: 0,52-5,15). Comparando sling retropúbico comtransobturatório, o retropúbico foi superior quanto às curas objetiva (RC: 1,27; IC95%: 1,05-1,54) e subjetiva (RC: 1,23; IC95%: 1,02-1,48). Entre minislings e outros slings, houve diferença favorável a outros slings quanto à cura subjetiva (RC: 0,58; IC95%: 0,39-0,86) mas não quanto à cura objetiva (RC: 0,72; IC95%: 0,47-1,10). No grupo sling pubovaginal e Burch, houve diferença quanto à cura objetiva (RC: 2,04; IC95%: 1,50-2,77) e subjetiva (RC: 1,64; IC95%: 1,10-2,44). Slings de uretra média apresentam mais erosão, enquanto a cirurgia de Burch tem mais complicações na ferida operatória e infecção do trato urinário. Slings retropúbicos e pubovaginais sãomais retencionistas. Slings retropúbicos estãomais associados a lesão vascular, hematomas e perfuração vesical, e transobturatórios, à dor na perna e virilha, lesão neurológica e perfuração vaginal. Conclusão Slings pubovaginais são superiores à cirurgia de Burch, porém mais retencionistas. Slings retropúbicos são superiores aos transobturatórios, embora tenham mais eventos adversos. Outros slings são superiores aos minislings em relação ao aspecto subjetivo. Não houve diferença nas comparações entre slings de uretra média e cirurgia de Burch, slings pubovaginais, transobturatórios inside-out e inside-in.

Abstract Objective To compare surgical treatments for stress urinary incontinence in terms of efficiency and complications. Data Sources We searched the MEDLINE and COCHRANE databases using the terms stress urinary incontinence, surgical treatment for stress urinary incontinence and sling. Selection of Studies Forty-eight studies were selected, which amounted to a total of 6,881 patients with scores equal to or higher than 3 in the Jadad scale. Data Collection Each study was read by one of the authors, added to a standardized table and checked by a second author. We extracted data on intervention details, follow-up time, the results of treatment and adverse events. Data Synthesis Comparing retropubic versus transobturator slings, the former was superior for both objective (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.05-1.54) and subjective (OR, 1.23; 95% CI, 1.02-1.48) cures. Between minislings versus other slings, there was a difference favoring other slings for subjective cure (OR, 0.58; 95% CI, 0.39- 0.86). Between pubovaginal sling versus Burch surgery, there was a difference for both objective (OR, 2.04; 95% CI, 1.50-2.77) and subjective (OR, 1.64; 95% CI, 1.10-2.44) cures, favoring pubovaginal sling. Therewas no difference in the groups: midurethral slings versus Burch, pubovaginal sling versus midurethral slings, transobturator slings, minislings versus other slings (objective cure). Retropubic and pubovaginal slings are more retentionist. Retropubic slings have more bladder perforation, and transobturator slings, more leg and groin pain, neurological lesion and vaginal perforation. Conclusion Pubovaginal slings are superior to Burch colposuspension surgery but exhibit more retention. Retropubic slings are superior to transobturator slings, with more adverse events. Other slings are superior to minislings in the subjective aspect. There was no difference in the comparisons between midurethral slings versus Burch colposuspension surgery, pubovaginal versus midurethral slings, and inside-out versus outside-in transobturator slings.

Resumo Realizou-se revisão sistemática emetanálise de estudos clínicos prospectivos, randomizados e placebo-controlados que comparavam a toxina botulínica ao placebo no tratamento da bexiga hiperativa. O objetivo primário desta metanálise foi avaliar a eficácia da toxina botulínica em relação à urgência urinária, frequência miccional, noctúria e episódios de incontinência. O objetivo secundário foi avaliar os efeitos adversos. Selecionamos estudos que incluíram somente pacientes com bexiga hiperativa não-neurogênica tratada com 100 unidades de onabotulinum toxina A ou placebo (grupo controle). Foram encontrados 532 estudos após as buscas iniciais, dos quais sete apresentaram todos os critérios de inclusão (estudos prospectivos, randomizados, placebo-controlados, ≥ 3pontosnaescalade Jadad) e fizeram parte desta análise. Para todos os objetivosprimários a toxina foimais eficaz do que o placebo, comp < 0,0001 e intervalo de confiança (IC) de 95%: urgência (diferençamédia = -2,07, IC=[-2,55; -1,58]), freqüênciamiccional (diferençamédia=-1,64, IC=[-2,10; -1,18]), noctúria (diferençamédia=-0,25, IC=[-0,39; -0,11]) e episódios de incontinência (diferença média = -2,06, IC= [-2,60; -1,52]). A necessidade de cateterização intermitente e a ocorrência de infecção urinária (ITU) forammais frequentes no grupo toxina na comparação como grupo placebo (p < 0,0001). A toxina botulínica promoveu melhora significativa dos sintomas de bexiga hiperativa na comparação com o placebo. Entretanto, está associada a uma maior incidência de cateterismo intermitente e infecção do trato urinário.

Abstract We performed a systematic review and meta-analysis of randomized placebo-controlled trials that studied non-neurogenic overactive bladder patients who were treated with 100 units of onabotulinumtoxinA or placebo. The primary purpose of our study was to evaluate the clinical effectiveness with regard to urinary urgency, urinary frequency, nocturia, and incontinence episodes. Our secondary purpose consisted of evaluating the adverse effects. Our initial search yielded 532 entries. Of these, seven studies met all the inclusion criteria (prospective, randomized, placebo-controlled studies, ≥ 3 points on the Jadad scale) and were selected for analysis. For all primary endpoints, the toxin was more effective than placebo (p < 0.0001; 95% confidence interval [95CI]), namely: urgency (mean difference = -2.07; 95CI = [-2.55-1.58]), voiding frequency (mean difference = - 1.64; 95CI = [-2.10-1.18]), nocturia (mean difference = -0.25; 95CI = [-0.39-0.11]) and incontinence episodes (mean difference = -2.06; 95CI= [-2.60-1.52]). The need for intermittent catheterization and the occurrence of urinary tract infection (UTI) were more frequent in patients treated with onabotulinumtoxinA than in patients treated with placebo (p < 0.0001). Compared with placebo, onabotulinumtoxinA had significantly and clinically relevant reductions in overactive bladder symptoms and is associated with higher incidence of intermittent catheterization and UTI.

Resumo Introdução Prolapso de órgãos pélvicos é problema de saúde públicas, sendo o mais comumo anterior. Para tratamento são utilizadas cirurgias, comou semtelas. O uso de telas é para diminuir recidivas, mas não h á consenso. Métodos Foi realizada revisão da literatura e metanálise, sobre uso de telas na correção do prolapso anterior. Base de dados foi PUBMED , com termos (MESH): "Anterior Pelvic Organ OR Cystocele AND Surgery AND (Mesh or Colporrhaphy)". Critérios de exclusão foram: seguimento menor que 1 ano, telas biológicas ou absorvíveis. Resultados: foram avaliados 115 artigos. Após revisão dos títulos, 70 estudos foram descartados e 18 após leitura de resumos. Após critérios de Jadad (>2), 12 estudos foram incluídos. Análise estatística foi razão de risco ou diferença entre médias dos grupos, e as análises com grande heterogeneidade foram avaliadas através de análise de efeito aleatório. Resultados Cura objetiva foi superior no grupo com tela - OR 1,28 (1,07-1,53, p 1 0,00001), maior perda sanguínea - diferença média (MD) 45,98 (9,72-82,25, p = 0,01), tempo cirúrgico mais longo - MD 15,08 (0,48-29,67, p = 0,04), porém menor recorrência - OR 0,22 (0,13-0,38, p = 0,00001), não apresentando maior resolução dos sintomas - OR 1,93 (0,83-4,51, p = 0,15). Dispareunia e taxa de reoperação também não foram diferentes entre grupos. Qualidade de vida não apresentou diferença. Conclusões Cirurgia com tela para prolapso vaginal anterior apresenta melhor taxa de cura anatômica e menor recorrência, sem diferenças cura subjetiva, reoperação e qualidade de vida. Há maior tempo cirúrgico e perda sanguínea. Uso de telas deve ser individualizado.

Abstract Purpose Pelvic organ prolapse (POP) is a major health issue worldwide, affecting 6- 8% of women. The most affected site is the anterior vaginal wall. Multiple procedures and surgical techniques have been used,with or without the use of vaginalmeshes, due to common treatment failure, reoperations, and complication rates in some studies. Methods Systematic review of the literature and meta-analysis regarding the use of vaginal mesh in anterior vaginal wall prolapse was performed. A total of 115 papers were retrieved after using the medical subject headings (MESH) terms: 'anterior pelvic organ prolapse OR cystocele AND surgery AND (mesh or colporrhaphy)' in the PubMed database. Exclusion criteria were: follow-up shorter than 1 year, use of biological or absorbable meshes, and inclusion of other vaginal wall prolapses. Studies were put in a data chart by two independent editors; results found in at least two studies were grouped for analysis. Results After the review of the titles by two independent editors, 70 studies were discarded, and after abstract assessment, 18 trials were eligible for full text screening. For final screening and meta-analysis, after applying the Jadad score (> 2), 12 studies were included. Objective cure was greater in the mesh surgery group (odds ratio [OR] = 1,28 [1,07-1,53]), which also had greater blood loss (mean deviation [MD] = 45,98 [9,72-82,25]), longer surgery time (MD = 15,08 [0,48-29,67]), but less prolapse recurrence (OR = 0,22 [01,3-0,38]). Dyspareunia, symptom resolution and reoperation rates were not statistically different between groups. Quality of life (QOL) assessment through the pelvic organ prolapse/urinary incontinence sexual questionnaire (PISQ-12), the pelvic floor distress inventory (PFDI-20), the pelvic floor impact questionnaire (PFIQ-7), and the perceived quality of life scale (PQOL) was not significantly different. Conclusions Anterior vaginal prolapse mesh surgery has greater anatomic cure rates and less recurrence, although there were no differences regarding subjective cure, reoperation rates and quality of life. Furthermore, mesh surgery was associated with longer surgical time and greater blood loss. Mesh use should be individualized, considering prior history and risk factors for recurrence.

Realizamos uma revisão sistemática e metanálise de estudos controlados e randomizados que avaliaram o tratamento conservador da incontinência urinária de esforço (IUE). Foram encontrados 1058 resultados depois das buscas iniciais, dos quais 37 trabalhos foram elegíveis de acordo com os critérios de inclusão. Para os desfechos primários, o treinamento muscular do assoalho pélvico (TMAP) foi mais eficaz do que nenhum tratamento em melhorar as escalas de qualidade de vida de incontinência (DM =[1]1,24 DPs; IC95% =[1]1,77 a [1]0,71 DPs), mas o efeito nos pad tests foi impreciso. A combinação do biofeedback com o TMAP teve um efeito incerto na qualidade de vida (DM=[1]4,4 pontos; IC95% =[1]16,69 a 7,89 pontos), mas melhores resultados no pad test, embora com heterogeneidade elevada (DM = 0,9g; IC95% = 0,71 a 1,10g); o grupo com TMAP não foi menos eficaz do que o tratamento individual, e o TMAP domiciliar não foi pior do que o TMAP supervisionado. Tanto a estimulação elétrica intravaginal (EEI) quanto a superficial (EES) foram melhores do que nenhum tratamento para a qualidade de vida e o pad test. Os cones vaginais apresentaram resultados mistos. A associação do EEI com o TMAP pode melhorar a eficácia deste último para a qualidade de vida e o pad test, mas os resultados dos estudos individuais não foram consistentes. Então, existe evidência para o uso do TMAP no tratamento da IUE, com e sem biofeedback.

We performed a systematic review and meta-analysis of randomized controlled trials that studied the conservative management of stress urinary incontinence (SUI). There were 1058 results after the initial searches, from which 37 studies were eligible according to previously determined inclusion criteria. For the primary outcomes, pelvic floor muscle training (PFMT) was more efficacious than no treatment in improving incontinence-specific quality of life (QoL) scales (SMD = [1]1.24SDs; CI 95% = [1]1.77 to [1]0.71SDs). However, its effect on pad tests was imprecise. Combining biofeedback with PFMT had an uncertain effect on QoL (MD = [1]4.4 points; CI 95% = [1]16.69 to 7.89 points), but better results on the pad test, although with elevated heterogeneity (MD = 0.9g; 95%CI = 0.71 to 1,10g); group PFMT was not less efficacious than individual treatment, and home PFMT was not consistently worse than supervised PFMT. Both intravaginal and superficial electrical stimulation (IES and SES) were better than no treatment for QoL and pad test. Vaginal cones had mixed results. The association of IES with PFMT may improve the efficacy of the latter for QoL and pad test, but the results of individual studies were not consistent. Thus, there is evidence of the use of PFMT on the treatment of SUI, with and without biofeedback.

RESUMO Objetivo: determinar o valor preditivo positivo da história clínica em comparação ao estudo urodinâmico para o diagnóstico da incontinência urinária. Método: análise retrospectiva comparando história clínica e avaliação urodinâmica em 1.179 mulheres com incontinência urinária. O estudo urodinâmico foi considerado padrão-ouro, e a história clínica, o novo teste a ser avaliado. Isso foi estabelecido após análise de cada método como padrão-ouro pela diferença entre seus valores preditivos positivos. Resultados: o valor preditivo positivo da história clínica comparado ao estudo urodinâmico para diagnóstico de incontinência urinária de esforço, bexiga hiperativa e incontinência urinária mista foram, respectivamente, 37% (IC95% 31-44), 40% (IC95% 33-47) e 16% (IC95% 14-19). Conclusão: o valor preditivo positivo da história clínica foi baixo quando comparado ao estudo urodinâmico para diagnóstico de incontinência urinária. O valor preditivo positivo foi baixo mesmo em mulheres com incontinência urinária de esforço pura.

SUMMARY Objective: to determine the positive predictive value of clinical history in comparison with urodynamic study for the diagnosis of urinary incontinence. Methods: retrospective analysis comparing clinical history and urodynamic evaluation of 1,179 women with urinary incontinence. The urodynamic study was considered the gold standard, whereas the clinical history was the new test to be assessed. This was established after analyzing each method as the gold standard through the difference between their positive predictive values. Results: the positive predictive values of clinical history compared with urodynamic study for diagnosis of stress urinary incontinence, overactive bladder and mixed urinary incontinence were, respectively, 37% (95% CI 31-44), 40% (95% CI 33-47) and 16% (95% CI 14-19). Conclusion: we concluded that the positive predictive value of clinical history was low compared with urodynamic study for urinary incontinence diagnosis. The positive predictive value was low even among women with pure stress urinary incontinence.

To evaluate the efficacy and safety of different bulking agents for treating urinary incontinence in women, a systematic review including only randomized controlled trials was performed. The subjects were women with urinary incontinence. The primary outcomes were clinical and urodynamic parameters. The results were presented as a weighted mean difference for non-continuous variables and as relative risk for continuous variables, both with 95% confidence intervals. Initially, 942 studies were identified. However, only fourteen eligible trials fulfilled the prerequisites. Altogether, the review included 1814 patients in trials of eight different types of bulking agents, and all studies were described and analyzed. The measured outcomes were evaluated using a large variety of instruments. The most common complications of the bulking agents were urinary retention and urinary tract infection. Additionally, there were certain major complications, such as one case of death after use of autologous fat. However, the lack of adequate studies, the heterogeneous populations studied, the wide variety of materials used and the lack of long-term follow-up limit guidance of practice. To determine which substance is the most suitable, there is a need for more randomized clinical trials that compare existing bulking agents based on standardized clinical outcomes.

OBJECTIVE: To evaluate vaginal cone therapy in two phases, passive and active, in women with stress urinary incontinence. METHODS: A prospective study was conducted at the Department of Obstetrics and Gynecology, São Paulo University, Brazil. Twenty-four women with a clinical and urodynamic diagnosis of stress urinary incontinence were treated with vaginal cones in a passive phase (without voluntary contractions of the pelvic floor) and an active phase (with voluntary contractions), each of which lasted three months. Clinical complaints, a functional evaluation of the pelvic floor, a pad test, and bladder neck mobility were analyzed before and after each phase. RESULTS: Twenty-one patients completed the treatment. The reduction in absolute risk with the pad test was 0.38 (p<0.034) at the end of the passive phase and 0.67 (p<0.0001) at the end of the active phase. The reduction in absolute risk with the pelvic floor evaluation was 0.62 (p<0.0001) at the end of the passive phase and 0.77 (p<0.0001) at the end of the active phase. The reduction in absolute risk of bladder neck mobility was 0.38 (p<0.0089) at the end of the passive phase and 0.52 (p<0.0005) at the end of the active phase. Complete reversal of symptomatology was observed in 12 (57.1%) patients, and satisfaction was expressed by 19 (90.4%). CONCLUSION: Using vaginal cones in the passive phase, as other researchers did, was effective. Inclusion of the active phase led to additional improvement in all of the study parameters evaluated in women with stress urinary incontinence. Randomized studies are needed, however, to confirm these results.
