Protocolo de Treino dos Músculos do Pavimento Pélvico em Mulheres com Incontinência Urinária de Esforço: Revisão Sistemática

Introdução: Os exercícios de fortalecimento dos músculos do pavimento pélvico (EFMPP) são considerados a primeira intervenção no tratamento da incontinência urinária de esforço (IUE), porém os EFMPP são distintos, não existindo evidência sobre os parâmetros de treino. Objetivo: Identificar o protocolo e/ ou os parâmetros de treino dos músculos do pavimento pélvico (MPP) mais eficaz no tratamento da IUE feminina. Método: A pesquisa bibliográfica foi realizada entre janeiro de 1992 a março de 2014 nas bases de dados PubMed, Cochrane Library, PEDro, web of Science e LILACS. Os artigos incluídos eram de língua inglesa, estudos experimentais, no qual comparavam EFMPP com o tratamento placebo, usual ou sem tratamento, com idade compreendida entre os 18 e os 65 anos e diagnóstico de IUE. Os critérios de exclusão abrangeram o diagnóstico de IUE desencadeada por fatores externos ao trato urinário inferior, grávidas, puérperas, prolapso ≥ 2 e outros tipos de IU. A avaliação da qualidade metodológica for realizada através da escala PEDro. Resultados: Sete artigos de elevada qualidade metodológica foram incluídos na presente revisão. A amostra foi constituída por 331 mulheres, com idade média de 44,4 anos, duração média das perdas urinárias de 64 meses e a gravidade da IUE variou entre ligeira a severa. Os programas de EFMPP eram distintos em relação aos parâmetros de treino dos MPP, sendo que alguns estudos incluíram o treino abdominal, supervisão e técnicas adjuvantes. A taxa de curada da quantidade de perda urinária variou entre 28,6 a 80%, enquanto a força dos MPP variou de 15,6% a 161,7%. Conclusão: Na presente revisão sistemática, os EFMPP combinados com palpação digital, biofeedback e cones vaginais parecem ser mais eficazes na redução da quantidade de perda urinária, comparado com os EFMPP isolados ou sem tratamento. Esta revisão permitiu igualmente identificar as 12 semanas de duração da intervenção, 10 repetições por série e diferentes posições, sendo os parâmetros de treino mais consistentes na redução dos sintomas.

Minimal Criteria for the Diagnosis of Avulsion of the Puborectalis Muscle by Tomographic Ultrasound

Introduction and hypothesis Puborectalis avulsion is a likely etiological factor for female pelvic organ prolapse(FPOP). We performed a study to establish minimal sonographic criteria for the diagnosis of avulsion. Methods We analysed datasets of 764 women seen at a urogynecological service. Offline analysis of ultrasound datasets was performed blinded to patient data. Tomographic ultrasound imaging (TUI) was used to diagnose avulsion of the puborectalis muscle. Results Logistic regression modelling of TUI data showed that complete avulsion is best diagnosed by requiring the three central tomographic slices to be abnormal. This finding was obtained in 30% of patients and was associated with symptoms and signs of FPOP (P<0.001). Lesser degrees of trauma (‘partial avulsion’) were not associated with symptoms or signs of pelvic floor dysfunction. Conclusions Complete avulsion of the puborectalis muscle is best diagnosed on TUI by requiring all three central slices to be abnormal. Partial trauma seems of limited clinical relevance.

High-field (3T) magnetic resonance defecography with functional assessment of the evacuation phase : a pictorial essay : P10

Purpose: Dynamic high-field magnetic resonance (MR) defecography including the evacuation phase is a promising tool for the assessment of functional pelvic disorders, nowadays seen with increasing frequency in elderly women in particular. Learning objectives: 1. To describe the adequate technique of dynamic high-field MRI (3T) in assessing pelvic floor disorders. 2. To provide an overview of the most common pathologies occurring during the evacuation phase, especially in comparison with results of conventional defecography. Methods and materials: After description of the ideal technical parameters of MR defecography performed in supine position after gel rectal filling with a 3 Tesla unit and including the evacuation phase we stress the importance of using a standardized evaluation system for the exact assessment of pelvic floor pathophysiology. Results: The typical pelvic floor disorders occurring before and/or during the evacuation phase, such as sphincter insufficiency, vaginal vault and/or uterine prolapse, cystourethrocele, peritoneo-/ entero-/ sigmoïdocele or rectal prolapse, are demonstrated. The difference between the terms "pelvic floor descent" and "pelvic floor relaxation" are pictorially outlined. MR results are compared with these of conventional defecography. Conclusion: Exact knowledge about the correct technique including the evacuation phase and the use of a standardized evaluation system in assessing pelvic floor disorders by dynamic high-field MRI is mandatory for accurate and reproducible diagnosis.

Urinary incontinence related to perineal muscle strength in the first trimester of pregnancy: cross-sectional study

Objective To analyze pelvic floor muscle strength (PFMS), urinary continence and quality of life related to urinary incontinence (UI) of women in the first trimester of pregnancy. Method Cross-sectional study with a sample of 500 women who started prenatal care in a complementary healthcare facility in Guarulhos, state of São Paulo, from 2012 and 2013. Pelvic floor muscle strength was evaluated through perineometry. The pregnant women who presented UI answered the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Results It was found that maternal age (OR=1.06; CI95% 1.02-1.11) and prior UI (OR=15.12; 95%CI 8.19-27.92) are the variables that, in tandem, best explain the occurrence of UI at the beginning of pregnancy. The mean score on the ICIQ-SF was 8.2 (SD=3.9), considered a moderate impact on quality of life. Conclusion Older pregnant women with prior UI are more likely to have UI in the first trimester of pregnancy.


A prospective randomised double-blind controlled trial evaluating the effect of trans-sacral magnetic stimulation in women with overactive bladder.

Overactive bladder (OAB) is a prevalent condition with 16% of adults having one or more symptoms that significantly affect quality of life. Transcutaneous electrical nerve stimulation and neuromodulators have had success in treating OAB but are expensive, invasive, and sometimes cumbersome. We developed an alternative neuromodulatory technique that involves electromagnetic stimulation of the sacral nerve roots with a portable electromagnetic device to produce trans-sacral stimulation of the S3 and S4 sacral nerve roots. The aim of this study was to evaluate the impact of this device on OAB symptoms in women with a prospectively randomised double-blind controlled study. Following a power analysis, women with symptoms of OAB were prospectively recruited with ethical approval for randomisation to an active treatment (n = 33) or placebo group (n = 30) in a double-blind trial. The patient, at home, used the belt device daily for 20 min over 12 weeks. Outcome measures included a 3-day voiding diary, 1 h pad test, visual analogue score (VAS) for symptom impact (0-100%), Kings Health Questionnaire (KHQ) and Australian Quality of Life questionnaire (AQOL) at baseline, 6 and 12 weeks. Overall, no difference was found between groups for any of the research questions. Specifically, we were unable to demonstrate any difference between the active and sham device groups in frequency, nocturia, urinary leakage, or quality of life, nor was there any evidence of a placebo effect. The quality of the data was high with the number of missing observations (especially for disease specific KHQ and general AQOL) being few. This attempt to promote trans-sacral electromagnetic neuromodulation with a specially created device was ineffective on the symptoms of OAB.

Bilateral extraperitoneal uterosacral vaginal vault suspension: a 2-year follow-up longitudinal case series of 123 patients.

INTRODUCTION AND HYPOTHESIS: The objective of this study is to assess anatomical and functional results of the extraperitoneal uterosacral ligament suspension (USL) in women with post-hysterectomy vaginal vault prolapse. METHODS: One hundred and twenty-three consecutive women were included. Concurrent procedures were anterior colporraphy with fascial repair (20%) and mesh reinforcement (49%), posterior colporraphy with fascial repair (38%) and mesh reinforcement (56%) and a sling procedure (29%). Women were assessed using Baden and Walker and pelvic organ prolapse quantification classification pre- and post-operatively. RESULTS: One hundred and ten patients (89%) were available for follow-up. Mean follow-up was 2 years. Objective success rate regarding the vaginal cuff is 95.4%. Global anatomical success rate was 85.5%. Urinary, coital and bowel symptoms were improved following surgery. Mesh exposure rate was 19.3%, with all cases managed conservatively or with minor interventions. CONCLUSION: Bilateral extraperitoneal USL is an effective operation to restore apical support with low morbidity, which avoids potential risks associated with opening the peritoneal cavity.

Continuous recording intrarectal pressures during the second phase of labor.

Parameters of intrarectal pressure (surface area under pressure curve and peak pressure) recorded with a microsystem device during the second phase of labor showed no significant correlations with baby's weight or mode of delivery. AIM OF THE STUDY: Was to assess the biomechanical pressures delivered against pelvic floor structures during the second phase of labor in nulliparae women, and to correlate them with obstetrics parameters, i.e. baby'sweight and mode of delivery. MATERIAL: Using a microsystem device placed into the rectum at the beginning of the second phase of labor, two parameters were assessed during the bearing efforts in 59 nulliparae women: the surface area under the pressure curve and the peak pressure. RESULTS: During 11.5±9 bearing efforts of 99.1±16s duration, the mean value of surface area under the pressure curve was 32677±26058cm/s and the mean value of the peak pressure was 60.7±24cmH(2)O, exceeding 100cmH(2)O in 10% of women. These two parameters were not correlated with baby's weight (R: 0.19, P: 0.15 and R: 0.05, P: 0.71). In the same way, these two parameters were not correlated with the mode of delivery (spontaneous or forceps/vacuum-assisted). Furthermore, the individual values of these two parameters showed great variation from one woman to another. CONCLUSION: This study has showed that parameters of biomechanical pressures recorded into the rectum during second phase of labor had no significant correlations with obstetricals parameters, explaining why these latter have poor predicitive value of further pelvic floor problems.

Surgical Treatment of Colorectal Cancer. Controversial Issues

Aims: This study was carried out to evaluate surgical treatment of colorectal cancer (CRC) with special interest in present status and controversial issues: stenting as a palliative procedure for metastasized CRC (I), duration of thromboprophylaxis after the surgical treatment of CRC (II), treatment of the increasing population of elderly people (III) and the quality of life (QoL) after surgery for rectal cancer with special reference to pelvic floor dysfunction (IV). Materials and methods: The material consisted of patients with CRC operated on at Turku University Hospital between 2003 and 2008. In study II the data was collected retrospectively from electronic archives. In other studies the follow-up data was collected at postoperative control visits. In study IV the RAND-36 standardized questionnaire and additional questions assessing urinary, sexual and anorectal dysfunction were used. Results: The results of the current study showed that self-expanding metallic stents provided an alternative to palliative surgery in the treatment of obstructive CRC. Low molecular heparin given s.c. for a median of 11 days until hospital discharge seemed to provide sufficient thromboprophylaxis after surgery. With preoperative selection elderly patients with rectal cancer were suitable for major surgery for rectal cancer with morbidity and mortality rates comparable to those in younger patients. There was no difference between preoperative and one year postoperative general QoL for operated rectal cancer patients. Postoperative pelvic dysfunction was associated with an impaired QoL in some dimensions. Conclusions: Many individual factors regarding the patient and the disease must be taken into account when making treatment decisions in CRC to ensure successful treatment of CRC, patient satisfaction and QoL.

Hérnia perineal após disjunçao da sínfise púbica: apresentação de caso e técnica para correção

Traunatic perineal hernia remains a rare clinical entity despite an overall increase in blunt trauma. Because of the incidence of other associated injuries, the mortality is high. Most of the perineal defects are repaired during the orthopaedics surgery to reconstitute the pelvis and few patients develop a true perineal hernia without pelvic instability. A 80-year-old woman was involved in a running over accident with disjunction of pubic symphysis, dislocation of sacrum-iliac junction and fracture of pubis and ischium. The patient was submitted to an orthopaedic surgery and latter development an perineal hernia through the genitalia. The diagnosis could be established with physical examination alone. Conventional radiology, computadorized tomography, and ultrasound should also be done to progran the surgery. The repair approach was performed using a marlex mesh, fixed in the pelvic bones, Cooper ligament, and the abdominal wall. The mesh was stood in a retro- peritoneal position, rebuilding the pelvic floor without reconstruction the pelvic bones. We conclude that this is an efficient approach to repair of traumatic postoperative perineal hernia, mainly in patients with high operative risk, when the osseous repair is not necessary.

Conservative Treatment of Stress Urinary Incontinence: A Systematic Review with Meta-analysis of Randomized Controlled Trials

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.

Earning logics of a portal solution for a medical device manufacturer

The need behind this thesis was in the development of a more modern earning logic for a pelvic floor muscle home training device to which a portal solution is going to be introduced as a part of new upgraded version of the device. The goal is to offer useful guidelines and recommendations for the medical device manufacturer to use in the process of creating the new business model around the new product version. In the theoretical part of this thesis, the used theoretical frameworks for business model generation and pricing models are presented. The special characteristics of healthcare technology industry are also introduced as initial data for the empirical part. The empirical data is collected via interviews and meetings from both inside and outside of the company to gain a comprehensive picture of the issue at hand. The needed changes in the business model as well as possible pricing options are gone through in the empirical chapters with the main focus being on the incoming revenue streams and pricing. As results of the thesis recommendations are presented for the changes that are needed in the business model after the introduction of the portal solution. The results of this thesis can be used for finishing the development process of the new version of the device and especially the earning logic of it.

Suivi à long terme de l’efficacité d’un traitement de physiothérapie sur l'incontinence urinaire d'effort persistante en période postnatale

L’incontinence urinaire d’effort (IUE) est une condition fréquente en période postnatale pouvant affecter jusqu’à 77% des femmes. Neuf femmes sur dix souffrant d’IUE trois mois après l’accouchement, vont présenter une IUE cinq ans plus tard. Le traitement en physiothérapie de l’IUE par le biais d’un programme d’exercices de renforcement des muscles du plancher pelvien est reconnu comme étant un traitement de première ligne efficace. Les études ont prouvé l’efficacité de cette approche sur l’IUE persistante à court terme, mais les résultats de deux ECR à long terme n’ont pas démontré un maintien de l’effet de traitement. L’effet d’un programme en physiothérapie de renforcement du plancher pelvien intensif et étroitement supervisé sur l’IUE postnatale persistante avait été évalué lors d’un essai clinique randomisé il y a sept ans. Le but principal de la présente étude était d’évaluer l’effet de ce programme sept ans après la fin des interventions de l’ECR initial. Un objectif secondaire était de comparer l’effet de traitement à long terme entre un groupe ayant fait seulement des exercices de renforcement du plancher pelvien et un groupe ayant fait des exercices de renforcement du plancher pelvien et des abdominaux profonds. Un troisième objectif était d’explorer l’influence de quatre facteurs de risques sur les symptômes d’IUE et la qualité de vie à long terme. Les cinquante-sept femmes ayant complétées l’ECR initial ont été invitées à participer à l’évaluation du suivi sept ans. Vingt et une femmes ont participé à l’évaluation clinique et ont répondu à quatre questionnaires, tandis que dix femmes ont répondu aux questionnaires seulement. L’évaluation clinique incluait un pad test et la dynamométrie du plancher pelvien. La mesure d’effet primaire était un pad test modifié de 20 minutes. Les mesures d’effets secondaires étaient la dynamométrie du plancher pelvien, les symptômes d’IUE mesuré par le questionnaire Urogenital Distress Inventory, la qualité de vie mesurée par le questionnaire Incontinence Impact Questionnaire et la perception de la sévérité de l’IUE mesuré par l’Échelle Visuelle Analogue. De plus, un questionnaire portant sur quatre facteurs de risques soit, la présence de grossesses subséquentes, la v présence de constipation chronique, l’indice de masse corporel et la fréquence des exercices de renforcement du plancher pelvien de l’IUE, venait compléter l’évaluation. Quarante-huit pour-cent (10/21) des participantes étaient continentes selon de pad test. La moyenne d’amélioration entre le résultat pré-traitement et le suivi sept ans était de 26,9 g. (écart-type = 68,0 g.). Il n’y avait pas de différence significative des paramètres musculaires du plancher pelvien entre le pré-traitement, le post-traitement et le suivi sept ans. Les scores du IIQ et du VAS étaient significativement plus bas à sept ans qu’en prétraitement (IIQ : 23,4 vs 15,6, p = 0,007) et (VAS : 6,7 vs 5,1, p = 0,001). Les scores du UDI étaient plus élevés au suivi sept ans (15,6) qu’en pré-traitement (11,3, p = 0,041) et en post-traitement (5,7, p = 0,00). La poursuite des exercices de renforcement du plancher pelvien à domicile était associée à une diminution de 5,7 g. (p = 0,051) des fuites d’urine observées au pad test selon une analyse de régression linéaire. Les limites de cette étude sont ; la taille réduite de l’échantillon et un biais relié au désir de traitement pour les femmes toujours incontinentes. Cependant, les résultats semblent démontrer que l’effet du traitement à long terme d’un programme de renforcement des muscles du plancher pelvien qui est intensif et étroitement supervisé, est maintenu chez environ une femme sur deux. Bien que les symptômes d’IUE tel que mesuré par les pad test et le questionnaire UDI, semblent réapparaître avec le temps, la qualité de vie, telle que mesurée par des questionnaires, est toujours meilleure après sept qu’à l’évaluation initiale. Puisque la poursuite des exercices de renforcement du plancher pelvien est associée à une diminution de la quantité de fuite d’urine au pad test, les participantes devraient être encouragées à poursuivre leurs exercices après la fin d’un programme supervisé. Pour des raisons de logistique la collecte de donnée de ce projet de recherche s’est continuée après la rédaction de ce mémoire. Les résultats finaux sont disponibles auprès de Chantale Dumoulin pht, PhD., professeure agrée à l’Université de Montréal.

Evaluación de disfunción sexual en pacientes sometidas a cabestrillo suburetral para corrección de incontinencia urinaria en el Hospital Universitario Mayor

Objetivo: establecer la prevalencia de la disfunción sexual en las pacientes sometidas a corrección de incontinencia urinaria por medio de la uretrocistopexia con cabestrillo en el Hospital Universitario Mayor. Metodología: se realizo un estudio analítico de corte transversal donde se evaluara la disfunción sexual en pacientes con incontinencia urinaria por medio de la encuesta PISQ-12 después de 6 meses de la realización de cabestrillo suburetral dentro del manejo de incontinencia urinaria femenina y buscarán la asociación con otros factores como el tipo de cirugía asociada al cabestrillo, menopausia, terapia hormonal, edad, número de embarazos utilizando la prueba de asociación ji-cuadrado de Pearson o el test exacto de Fisher o razón de verosimilitud exacta (valores esperados < 5). Resultados: la prevalencia de disfunción sexual fue del 27% (12 pacientes), de ellas 25% tuvieron disfunción moderada (11 pacientes) y dos por ciento disfunción severa (1 paciente) deacuerdo con la escala PISQ-12. La disfunción sexual fue más frecuente en las pacientes con prolapso posterior estadio 2 (4 de las 5 mujeres), seguido del prolapso anterior y posterior estadio 2 (4 de 10 mujeres), las otras categorías fueron menores, mostrando asociación significativa (p=0.011, Test exacto de Razón de verosimilitud). Conclusión: del presente estudio podemos concluir que la cirugía de piso pelvico (colporrafías) contomintante a la cirugía de incontinencia urinaria con cabestrillo suburetral está asociada a un mayor grado de disfunción sexual femenina.
