Tradução para português, adaptação cultural e validação do Female Sexual Function Index / Translation into Portuguese, cross-national adaptation and validation of the Female Sexual Function Index

OBJETIVO: traduzir para o português, adaptar culturalmente e validar o questionário Female Sexual Function Index (FSFI). MÉTODOS: dois tradutores brasileiros, cientes dos objetivos desta pesquisa, preparam duas versões do FSFI para o português, as quais foram retro-traduzidas por outros dois tradutores ingleses. As diferenças foram harmonizadas e pré-testadas em um estudo piloto. As versões finais do FSFI e de outro questionário, o Short-Form Health Survey, já vertido e publicado em português, foram simultaneamente administradas a cem pacientes. Foram testadas as propriedades psicométricas do FSFI, como confiabilidade (consistência interna e teste-reteste) e validades de construto. O reteste foi realizado após quatro semanas, a partir da primeira entrevista. RESULTADOS: o processo de adaptação cultural não alterou a versão em português do FSFI comparado ao original. O alfa de Cronbach padronizado do questionário foi 0,96; avaliado por domínios, variou de 0,31 a 0,97. Como medida de confiabilidade teste-reteste, foi aplicado o coeficiente de correlação intra-classes, que foi considerado forte e idêntico (1,0). O coeficiente de correlação de Pearson entre o FSFI e o Short-Form Health Survey foi positivo, mas fraco na maioria dos domínios afins, variando de 0,017 a 0,036. CONCLUSÕES: a versão do FSFI foi traduzida para o português e adaptada culturalmente e é válida para avaliação da resposta sexual das mulheres brasileiras.

PURPOSE: to translate from English into Portuguese, adapt culturally and validate the Female Sexual Function Index (FSFI). METHODS: knowing the objectives of this research, two Brazilian translators have prepared a version each from the FSFI into Portuguese. Both versions have then been retro-translated into English by two English translators. After harmonizing the differences, they have been pre-tested in a pilot study. The final versions from the FSFI and from another questionnaire, the Short-Form Health Survey, which had already been translated and published in Portuguese, have then been simultaneously administered to one hundred patients, to test the FSFI psychometric proprieties concerning reliability (internal consistency and testing-retesting) and construct validity. Retesting was done after four weeks from the first interview. RESULTS: the process of cultural adaptation has not altered the Portuguese version of the FSFI, as compared to the original. The FSFI standardized Cronbach alpha was 0.96, and the evaluation by domains has varied from 0.31 to 0.97. As a measure of test-retest confidentiality, it was applied the intra-class coefficient, which has been considered strong and identical (1.0). Pearson's correlation coefficient between the FSFI and the Short-Form Health Survey was positive, but weak in most of the interrelated domains, varying from 0.017 to 0.036. CONCLUSIONS: the FSFI English version has been translated into Portuguese and culturally adapted, being reliable to evaluate the sexual response of Brazilian women.

Defeitos do compartimento vaginal posterior: fisiopatologia e tratamento da retocele / Defects of vaginal posterior compartment: pathophysiology and treatment of rectocele

A retocele é definida como uma herniação da parede anterior do reto e posterior da vagina em direção ao lúmen vaginal. A etiologia da retocele é variada, e como tal, o tratamento deve ser sítio específico. Apenas a miorrafia dos elevadores pode não resolver o problema e comprometer a evacuação, bem como dificultar o acesso ao sítio específico do defeito em futuras intervenções cirúrgicas. O uso de telas sintéticas, especialmente as de polipropileno, se mostra como um recurso valioso nas mulheres que apresentam o septo retovaginal muito atrófico ou com lesão extensa, que impossibilita sua reconstituição.

Aspectos atuais no tratamento do prolapso de cúpula vaginal / Current aspects of treatment of vaginal vault prolapse

O prolapso de cúpula vaginal é uma complicação tardia da histerectomia vaginal e sua incidência está estimada na faixa de 2-3,6/1.000 mulheres-ano a 15/1.000 mulheres-ano nas pacientes cuja indicação da histerectomia tenha sido o prolapso. Há várias técnicas cirúrgicas para o tratamento desta distopia com os mais variados índices de sucesso e complicações, porém as duas mais usadas são a colpopexia sacral (por via abdominal) e a colpopexia no ligamento sacro-espinhal (por via vaginal). Recentemente uma nova técnica veio se somar ao arsenal cirúrgico do tratamento do prolapso de cúpula vaginal com uma boa taxa de cura e baixa incidência de complicações: a slingoplastia intravaginal posterior (IVS Posterior)

Resiniferatoxin for detrusor instability refractory to anticholinergics

PURPOSE: We have evaluated the clinical and urodynamic effects of intravesical instillation of resiniferatoxin in patients with idiopathic detrusor instability refractory to anticholinergics. MATERIALS AND METHODS: There were 30 women, median age 56 years old with detrusor instability for over 6 months and a history of anticholinergic use with no response or intolerable collateral effects. A 50 nM solution of resiniferatoxin was prepared for intravesical instillation. All patients were evaluated for urinary symptoms, as well as for urodynamic assessments before and 30 days after instillation. Tolerability was analyzed during the instillation. RESULTS: A clinical improvement was observed in 30 percent of the patients with urinary urgency and in 33 percent of the patients with urge-incontinence. The mean maximum cystometric capacity before application was 303.9 ± 78.9 and after application 341 ± 84.6. No significant difference was observed (p = 0.585). The mean maximum amplitude of the contractions diminished from 47.86 ± 29.64 to 38.72 ± 30.77 (p = 0.002). CONCLUSIONS: Resiniferatoxin, in this concentration, proved to be useful in a small percentage of patients regarding clinical detrusor instability. Maximum amplitude of the involuntary contractions was significantly reduced and in 33 percent patients the involuntary contractions disappeared. Further studies with different concentrations are recommended.

Safyreã: a readjustable minimally invasive sling for female urinary stress incontinence

INTRODUCTION: SAFIRE TM is a readjustable and minimally invasive sling for the treatment of stress urinary incontinence (SUI). It is as a pubovaginal sling placed in the medial third of the urethra. The initial experience is described. MATERIALS AND METHODS: Forty-five patients (mean age = 59 years) underwent a SAFYRE TM implant to treat SUI. Physical examination and urodynamic study were performed before surgery. All patients presented symptoms of SUI and 20 percent also reported mild urgency. Approximately 60 percent of this group had a previously failed anti-incontinence procedure. Urethral hypermobility was diagnosed in 40 percent of the patients and intrinsic sphincter deficiency (ISD) in 60 percent of the cases. RESULTS: The average follow up period was 10 months. The mean operative time was 20 minutes. Dystopia repair was performed whenever necessary, during the same procedure. The average hospital stay was 24 hours. In 11 percent of the implants, bladder perforation occurred. During the postoperative period, 9 patients (20 percent) developed transient urgency symptoms. During the initial follow up period, 90 percent were found to be continent, 3 percent reported an improvement and 7 percent were unchanged. CONCLUSION: SAFYRE TM is a safe and quick procedure that allows postoperative readjustment. This technique may be an attractive alternative in the management of SUI, should the good result obtained so far prove to be long lasting.

Emprego da submucosa intestinal suína em uretroplastias complexas / The use of porcine intestinal submucosa for complex urethroplasty

We report the use of Porcine Intestinal Submucosa (PIS) in association with Johanson technique for urethroplasty, in the treatment of recurring urethral stenosis. The patient had obliterans xerotica balanitis and had previously undergone 15 internal uretotomies as well as various unsuccessful urethral dilations. As a result of stenotic extension, another surgery was planned using Johanson technique. During the first part of the surgery, intense local fibrosis was observed, which required greater care and protection to avoid fistulae formation. PIS was interposed to reduce the chances of the occurrence of this dreaded complication. During the second part of the surgery, a skin flap obtained from tissue parallel to the urethral plateau was used to prepare a neourethra according to the norms of this technique. PIS was fixed at its extremities, and interposed between the neourethral suture and the skin suture to prevent any contact between them. The procedure was completed with the use of meatoplasty and glandulaplasty. After 6-month follow up, clinical and urodynamic improvement could be seen. If these results can be confirmed by more extensive studies, PIS will provide new perspectives for complex urethroplasties.
