A research report submitted to the Faculty of Health Sciences, University of the Witwatersrand,Johannesburg, in partial fulfillment of the requirements for the degree of Master of Medicine in Obstetrics and Gynaecology. MMed (O & G) Johannesburg 2015 / Background: Stress urinary incontinence is a common problem in a woman’s life and has a negative affect on her quality of life (QOL). The trans obturator tape (TOT) is a safe procedure used to treat urinary incontinence. The operative change in the quality of life was determined using the Kings Health Questionnaire (KHQ). This study assesses patient reported outcomes of the TOT procedure as the primary measure of success. Objectives: The primary objectives of the study were to determine the subjective outcome of the QOL and symptoms for women that underwent the TOT procedure using the King’s Health Questionnaire (KHQ) in a tertiary academic centre. The secondary objectives assessed the cure rate of the impact on QOL and the subjective symptoms, evaluated the outcome of pre-operative urgency and determined if post-operative change in urinary incontinence correlates with personal relationships (sexual function). Method: This was a prospective cohort study design whereby patients answered the KHQ pre operatively on admission and post operatively at 6-24 months from January 2010 until June 2013. Seventy-seven patients took part in this study. Ten of these patients were excluded. The results were analysed separately in 3 groups.Stress urinary incontinence SUI (n=50), Mixed urinary incontinence MUI (n=4), SUI with a sensation of urgency (n=13). Logistic regression was used to determine the results. Results: Those patients who improved their QOL score by >75% for the SUI and MUI groups were 83% and 50% respectively. The positive improved change in QOL for the SUI and MUI groups were 98% and 100% respectively. Those patients who improved their subjective symptoms score by >75% for the SUI and MUI groups were 69%, and 92% respectively. The positive change in improvement of the symptoms for SUI and MUI groups were 100% and 75% respectively. Those patients who improved their stress symptoms score by >75% for SUI and MUI groups were 91% and 82% respectively. The subjective disappearance of urgency post operatively was 69% for the SUI with sensation of urgency group and 25% for the MUI group. Conclusions The trans obturator tape procedure conclusively improves the quality of life for women with stress urinary incontinence.There are very few studies that use subjective outcomes as their primary outcome measure. While most studies use the objective cure rate by using a negative cough test and more stringently a pad weight test. It is important to compare the study outcome results to other comparative studies using subjective outcomes rather than objective outcomes. Women should be counseled preoperatively about realistic expectations after surgery as this effects the operative outcome. In other studies subjective cure has been inconsistently assessed. There is a strong need for a standardized definition for subjective cure rate by the International Continence Society.

Foram estudados, prospectivamente, por um período médio de 4,9 anos, os resultados do tratamento de 31 mulheres com incontinência urinária e afecção benigna do útero que foram submetidas à cirurgia de sling fascial associada à histerectomia vaginal, atendidas na Clínica Ginecológica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, no período de fevereiro de 2000 a outubro de 2006. O objetivo foi avaliar os resultados do tratamento comparando-se os diagnósticos urodinâmicos pré- e pós-tratamento. As mulheres foram submetidas à cirurgia de histerectomia vaginal, para tratamento da afecção benigna do útero e sling fascial para correção da incontinência urinária. Realizou-se estudo urodinâmico no pré- e pós-tratamento, para avaliação da taxa de cura da incontinência urinária e do comportamento vesical nas fases de enchimento e esvaziamento, os quais foram avaliados por meio dos parâmetros urodinâmicos de fluxometria e cistometria. Na fluxometria avaliou-se o fluxo urinário máximo, fluxo urinário médio e volume de urina residual e na cistometria, determinou-se a capacidade vesical no 1° desejo miccional, capacidade vesical máxima e a pressão vesical necessária para ocorrer ou não a perda de urina. Os resultados mostraram, em relação á fluxometria diminuição significante do fluxo máximo, tendência à diminuição do fluxo médio e redução significante do volume de urina residual. Em relação à cistometria, houve aumento estatisticamente significante da capacidade vesical no 1° desejo miccional, da capacidade vesical máxima e valor da pressão vesical necessária para avaliar a presença ou não de perda urinária. Com relação ao diagnóstico urodinâmico, foi demonstrada a cura da incontinência urinária em 96,8% dos casos. Avaliando-se os parâmetros de cura objetiva da incontinência urinária, em seguimento de 4,9 anos, podemos inferir que o tratamento da incontinência urinária de esforço pode ser realizado simultaneamente, quando houver também, a indicação de histerectomia vaginal / We studied, prospectively, for a 4.9 years period the results of the treatment of 31 women with urinary incontinence and benign uterine disease that were submitted the surgery fascial sling associated to vaginal hysterectomy, the patients were all treated in the Gynecology Department of the Clinic Hospital of the University of Sao Paulo, in the period between February 2000 to October 2006. The objective was evaluate the results of the treatment comparing the urodinamic diagnosis pre and post treatment. All women were submitted to vaginal hysterectomy for treatment of benign uterine disorders and to facial sling to treat the urinary incontinence. An urodinamic study was performed pre and post treatment to define the rate of cure of the urinary incontinence and vesical behaviour in the filling and emptying fases, witch will evaluate through urodinamic parameters of flowmetry and cystometry, In the flowmetry were evaluated maximum urinary flow, medium urinary flow and residual urinary volume; and in the cystometry were determinated the bowel capacity in the first urinary desire, maximum bowel capacity in the first urinary desire, maximum bowel capacity and the needed bowel pressure to occur or not the urinary loss. The results showed in relation to the flowmetry significant reduction of the maximum flow, medium flow and urinary residual volume. In relation to cystometry we demonstrated an increase statistically significant in the vesical capacity in the first miccional desire, in the maximum bowel capacity and the value of the bowel pressure to evaluate the presence or not of urinary lost. In relation to the urodimanic diagnosis we could demonstrate the cure of urinary incontinence in 96.8% of cases. Evaluating the parameters of objective cure of urinary incontinence, in a follow up of 4.9 years, we can affirm that the treatment of urinary incontinence should be always be together with the vaginal hysterectomy when it is needed

Background: Urinary incontinence (UI) and urgency are common conditions and can have a profound influence on many aspects of life. Approximately one in four women has UI and one in ten has daily symptoms. Knowledge is lacking, however, on the impact of UI and urgency on the lives of affected women and their partners and on the situation of women with urinary leakage one year postoperatively. Aims: To study the consequences of female UI and urgency for patients and their partners on quality of life (QoL), the partner relationship, and their sexual lives. Also to evaluate the success rates of three operation methods: tension-free vaginal tape (TVT), tension-free vaginal tape-obturator (TVT-O), and transobturator tape (TOT) for stress urinary incontinence (SUI), with a particular focus on women who still have urinary leakage one year after surgery. Methods: Women seeking healthcare for UI and/or urgency and their partners were invited to answer questionnaires. The women completed disease-specific questionnaires and both the women (n = 206) and their partners (n = 109) answered questions about their psychosocial situation, partner relationship, and sexual life. Patient-reported outcomes one year after surgery with TVT, TVT-O, or TOT (n = 3334) were derived from the Swedish National Quality Register for Gynaecological Surgery. Results: Most of the women reported that their urinary problems negatively affected their physical activities, and almost half reported negative consequences for their social life. Women aged 25–49 years were less satisfied with their psychological health, sexual life, and leisure than women aged 50–74 years. One third of both the women and their partners (all the partners were men) experienced a negative impact on their relationship, and sexual life was negatively affected in almost half of the women and one in five of their men. Coital incontinence was reported in one third of the women. Most of their men did not consider this a problem, but the majority of the affected women did. Satisfaction with outcome of the operation did not differ between TVT, TVT-O, and TOT, but TVT showed a higher success rate for SUI than TOT did. Higher age, higher body mass index, a diagnosis of mixed urinary incontinence, and a history of urinary leakage in combination with urgency each constitute a risk for a lower operation success rate. After one year, 29% of the women still had some form of UI, but half of these were satisfied with the outcome and most reported fewer negative impacts on family, social, working, and sexual life than before the operation. Conclusions: Female UI and/or urgency impaired QoL, particularly in young women, and had negative effects on partner relationships and on some partners’ lives. Sexual life was also affected, more often in women with UI and/or urgency than in their partners. At one-year follow-up after surgery, about one third of the women still had some form of UI, but the negative impact on their lives was reduced. A challenge for health care professionals is to initiate a dialogue with women with urinary symptoms about sexual function and what surgery can realistically be expected to accomplish.

Para sua eficácia, exigem um mecanismo de ancoragem adequado. O objetivo deste estudo foi comparar as características biomecânicas de sistemas de fixação de dois modelos de mini slings atualmente disponíveis no mercado (Ophira® e Mini Arc®) por meio de teste de tração uniaxial em modelo murino ex vivo. Materiais e Métodos: Os dispositivos de ancoragem dos mini sling foram implantados cirurgicamente na parede abdominal de 15 ratos divididos em três grupos de cinco animais. Estes grupos foram sacrificados de acordo com a data pós implante em 7, 14 e 30 dias. Na sequência, extraia-se em bloco a parede abdominal de cada animal contendo os dispositivos de fixação. Este material era submetido a teste de tração até o despreendimento do sistema de ancoragem a partir do tecido leito de implante. Foram determinadas a medida da carga máxima (N) e deformação total (mm) até a avulsão. Os resultados foram comparados por meio do teste t de Student e o valor de p 5% foi considerado significativo. Resultados: O sistema de fixação do mini sling Ophira® em comparação ao Mini Arc® exigiu maior carga máxima para avulsão do tecido abdominal nos 3 períodos avaliados com significância estatística: 7º dia, 5,14 ± 0,69 N versus 4,11 ± 0,81 N (p 0,037), 14º dia 10,64 ± 0,81 N contra 9,02 ± 0,54 N (p 0,001) e no 30º dia 18,76 ± 1,48 N versus 14,85 ± 1,28 N (p < 0,001), respectivamente. Quanto ao deslocamento ocorrido durante a tração, o Ophira® desenvolveu maior deflexão significante em todos os momentos avaliados: no dia 7, 11,14 ± 0,53 mm enquanto o Mini Arc® 7,89 ± 1,01 mm (p 0,001), no dia 14 15,80 ± 0,95 mm versus 12,49 ± 1,43 mm (p < 0,001) e no trigésimo dia os valores foram 23,95 ± 1,38 mm contra 18,24 ± 0,50 mm (p < 0,001), respectivamente. Conclusão: O dispositivo de ancoragem do mini sling Ophira® proporcionou melhor fixação à parede abdominal murina em relação ao do Mini Arc®. Este resultado foi mantido mesmo no período pós-operatório tardio / Abstract: Introduction and hypothesis: Slings are currently the standard treatment for stress urinary incontinence. To be effective, they require an adequate anchoring system. The aim of this study is compare the biomechanical features of fixation systems of two mini slings models currently available on the market (Ophira¿ and Mini Arc¿). Materials and Methods: Anchoring devices of each sling were surgically implanted in the abdominal wall of 15 rats divided into three groups of five animals. These groups are formed according to the date of post implant euthanasia on 7, 14 and 30 days. Each abdominal wall was extracted in block containing the mini sling fixation device and was submitted to a tensile strength test for measure the maximum load and total deflection until device avulsion from the tissue. The results were compared using Student test t and a 5% cut off was considered significant. Results: The Ophira¿ mini sling fixation system demanded a greater maximum load compared to the Mini Arc¿ for avulsion of abdominal tissue in 3 evaluation periods with statistical significance: 7th day, 5.14 ± 0.69 versus 4.11 ± N 0,81 N (p 0.037), on day 14 10.64 ± 0.81 N versus 9.02 ± 0.54 N (p 0.001) and on day 30 18.76 ± 1.48 N versus 14.85 ± 1.28 N (p <0.001), respectively. Regarding the displacement occurred during traction, the Ophira¿ has developed significant higher deflection at all times evaluated: on day 7, 11.14 ± 0.53 mm while the Mini Arc¿ 7.89 ± 1.01 mm (p 0.001), on day 14 15.80 ± 0.95 versus 12.49 mm ± 1.43 mm (p <0.001) and on day 30 the values were 23.95 ± 1.38 mm vs. 18.24 ± 0.50 mm (p <0.001), respectively. Conclusion: The Ophira¿ mini sling anchoring device provided better fixation to the host tissue site compared to the Mini Arc¿ device in rats. This outcome were maintained even in the late post operative period / Mestrado / Fisiopatologia Cirúrgica / Mestre em Ciências

Background Female stress urinary incontinence (SUI) greatly affects quality of life. The midurethal sling (MUS) procedure has been widely accepted as the standard of care treatment for SUI, although there is little information regarding patients' subjective reports of symptom improvement. Objectives The objective of this study was to identify clinical and demographic characteristics that predict subjective symptom improvement following MUS procedures in women with SUI. Materials and Methods The study design was retrospective cohort. Subjects included women who underwent MUS between 2006 and 2008, returned mailed surveys and met our predefined inclusion criteria. Pre-operative data included demographics, prior surgery, co-morbid diseases, urodynamics and concomitant reconstructive surgery. Subjective improvement was measured by score improvement on the UIQ-7, UDI-6, the UDI stress subscale and Question 3 of the UDI, "Do you experience urine leakage related to physical activity, coughing, or sneezing?" Results The mean age of the study sample was 57 years, parity was 2.5 and BMI was 28. Subjects with lower MUCP demonstrated more improvement on the UIQ-7. ΔUDI-6 stress subscale scores were more sensitive to symptom change than either the ΔUDI-6 or ΔUIQ-7. Older, menopausal subjects with urethral hypermobility and concomitant vaginal suspension showed less improvement than subjects without these characteristics. After controlling for urethral straining angle, PVR, menopause and time out from surgery, older age and concomitant vaginal suspension were associated with persistent post-op symptoms on the UDI-6 Question 3 and age remained the only variable associated with persistent symptoms on the UDI-6 stress subscale. Conclusion Concurrent vaginal suspension and advancing age were risk factors for persistent symptoms following MUS procedures in patients with SUI. Symptoms may recur after 24 post-operative months. Clinicians are encouraged to provide additional preoperative counseling to those women who are at greatest risk for persistent symptoms.

Mulheres com prolapso genital estádio 3 e 4 são consideradas de risco para desenvolver incontinência urinária de esforço após a correção cirúrgica do prolapso. A provável explicação para estas pacientes manterem-se, subjetivamente, continentes seria porque o prolapso poderia gerar um acotovelamento na uretra ou compressão da mesma. O objetivo do estudo foi avaliar o impacto de procedimentos anti-incontinência durante a correção cirúrgica de prolapso genital estádio 3 e 4 em mulheres sem sintomas de incontinência urinária de esforço. Método: Realizou-se revisão sistemática com ensaios clínicos. A casuística incluiu mulheres com prolapso genital estádio 3 e 4 sem sintomas clínicos de incontinência urinária de esforço. O desfecho primário foi a presença de incontinência urinária ou necessidade de tratamento para incontinência urinária. Os resultados serão apresentados com o risco relativo, com 95% de intervalo de confiança. Resultados: Inicialmente, 5618 estudos foram identificados com a estratégia de busca, mas apenas oito preencheram os critérios de inclusão. Realizou-se metanálise com as variáveis em comum dos estudos que tivessem mesma escala de quantificação. Observou-se que realizar qualquer procedimento anti-incontinência no mesmo momento do tratamento cirúrgico do prolapso não reduziu a incidência de incontinência urinária no pós-operatório (RR 0.61; 95%CI 0.34-1.10]). Todavia, quando os procedimentos são analisados separadamente, encontraram-se resultados distintos. O subgrupo de pacientes submetidas ao sling retropúbico foi o único que diminuiu a incidência de IUE (RR 0.09; 95%CI 0.02-0.36). Conclusão: O tratamento profilático em mulheres com prolapso genital estádio 3 e 4 com sling retropúbico reduziu a incidência de IUE / Women with high-grade pelvic organ prolapse (POP) are considered at risk of developing postoperative stress urinary incontinence (SUI) once the prolapse has been repaired The probable explanation for the patients to remain subjectively continent, is that POP can affect the urethra by urethral kinking or compression. Our objective was to evaluate the impact of anti-incontinence procedures during surgical POP correction stage 3 and 4 in women with no symptoms for stress urinary incontinence. Methods: A systematic review of randomized trials was performed. The subjects were women with severe POP and no symptoms of SUI. The primary outcomes were UI or treatment for this condition after the surgical procedure. The results were presented as relative risk (RR), with 95% confidence interval (95%CI). Results: Initially, 5618 studies were identified by the search strategy, but only eight trials met the inclusion criteria. We performed a meta-analysis with common variables of studies and with the same scale of quantification. We found that performing an anti-incontinence procedure at the same time of prolapse repair did not reduce the incidence of (SUI) post-operatively (RR 0.61; 95%CI 0.34-1.10]). However, when the types of anti-incontinence procedure were analyzed separately, we found different results. The subgroup of patients who underwent a retropubic sling surgery was the only one that benefited from the antiincontinence procedure, with a decrease in the incidence of SUI (RR 0.09; 95%CI 0.02- 0.36). Conclusions: A prophylactic treatment of women with severe POP using retropubic sling reduced the risk of SUI

Técnicas igualmente eficazes, porém com menores riscos de complicações têm sido pesquisadas. Os mini-slings, utilizando incisão única e de acesso exclusivamente vaginal podem representar uma alternativa à técnica de sling tradicional. Objetivo: Avaliar a eficácia do mini sling Ophira para o tratamento da incontinência urinária de esforço feminina. Material e Método: Foram avaliadas 49 mulheres que compareceram ao Ambulatório de Uroginecologia do HC da UNICAMP no período de abril de 2008 a maio de 2009 com queixa clínica de incontinência urinária de esforço. Todas as pacientes foram submetidas a Estudo Urodinâmico pré-operatório e avaliadas através de história clínica, exame físico, urina I e urocultura, teste de esforço, Pad test de uma hora e aplicação do questionário de qualidade de vida UDI-6. A colocação de mini sling Ophira foi realizada sob anestesia local em regime ambulatorial com alta após micção espontânea. As avaliações subsequentes foram realizadas após seis dias e um, três, seis e 12 meses após o procedimento, compreendendo exame físico, Pad test de uma hora e aplicação do UDI-6. A cura objetiva foi avaliada através do Pad test e do teste de esforço. A cura subjetiva foi avaliada pela queixa clínica e pelo questionário de qualidade de vida. Resultados: A análise da percepção subjetiva dos resultados demonstrou que, após 12 meses de seguimento, 37 pacientes (76%) referiram cura da IUE e sete (14%) melhora. O escore do questionário UDI-6, inicialmente com média de 41,29, caiu para 7,24 após 12 meses de seguimento. O Pad test de uma hora apresentou queda de 6,2g no préoperatório para 1g após o término do acompanhamento. Apenas seis pacientes apresentavam teste de esforço positivo no seguimento de 12 meses. Não houve complicações intra-operatórias. Apenas um caso de dor pós-operatória foi observado. Obteve-se taxa de extrusão do sling de 12,2%. Conclusão: O mini sling Ophira representa uma alternativa cirúrgica segura e eficaz para o tratamento da incontinência urinária de esforço feminina, no período de tempo avaliado / Abstract: Introduction: The synthetic slings marked the transition from invasive treatment to minimally invasive treatment of stress urinary incontinence. Techniques equally effective but with fewer risks of complications have been proposed. The minislings, with single incision and accessing exclusively the vaginal route represents an alternative to tradicional sling technique. Objective: To evaluate the efficacy of mini sling Ophira for the treatment of stress urinary incontinence in women. Methods: We evaluated 49 women attending the outpatient clinic of Urogynecology at the HC/UNICAMP from April 2008 to May 2009 with clinical complaints of stress urinary incontinence. All patients were initially submitted to urodynamic investigation, clinical and physical evaluation, urine analysis, stress test, 1-hour pad test and UDI- 6 Quality of life questionnaire. Mini sling Ophira was placed under local anesthesia and patients were dismissed after spontaneous voiding. Evaluation was undertaken 6 days after surgery and 1, 3, 6 and 12 months follow-up. Objective cure was assessed by Pad test and stress test. Subjective cure was assessed by QoL questionnaire. Results: Subjective analysis demonstrated that, after 12 months, 37 (76%) of patients referred themselves as cured and 7 (14%) as improved. UDI score significantly dropped from 41.29 to 7.24 and 1 hour Pad-test significantly decreased from 6.2 g to 1.0 g. Only 6 patients had persistent positive stress test. No intra operative complications occurred and only one patient complained of pain. Mesh erosion rate was 12.2%. Conclusion: Mini sling Ophira represents a safe and effective alternative to female stress urinary incontinence treatment, should the results proved to be long lasting / Mestrado / Fisiopatologia Cirúrgica / Mestre em Ciências
