The outcome of transobturator anterior vaginal wall prolapse repair using porcine dermis graft: intermediate term follow-up

Introduction and Hypothesis We evaluated the anatomical success and complications of Perigee® with porcine dermis Graft in the repair of anterior vaginal wall prolapse (AVWP) Materials and Methods After Institutional Review Board (IRB) approval, the charts of all patients who underwent AVWP repair using the Perigee/InteXen® kit from July 2005 to July 2009 were reviewed. Patients who had less than 6-month follow-up were excluded. Preoperative data including patient age, previous AVWP repairs, hysterectomy status, preoperative dyspareunia and pertinent physical findings were collected and recorded. Postoperative success was defined as anatomical stage 0 or I using the Pelvic Organ Prolapse Quantification (POP-Q) scoring system. Graft related complications were also recorded. Results Out of 89 patients, 69 completed at least 6-month follow-up. Median follow-up was 13 (6-48) months. Seventeen patients (25%) had previous AVWP repair and 32 (46%) had previous hysterectomy. Preoperatively, AVWP stage II was found in 9 (13%), stage III in 27 (39%) and stage IV in 33 (48%) patients. Anatomic success was found in 48 (69%) patients, with 23 (33%) having stage 0 and 25 (36%) stage I AVWP. Intraoperative complications included incidental cystotomy in one patient and bladder perforation in one. Postoperative complications included vaginal exposure and dyspareunia in one case, wound dehiscence in one and tenderness over the graft arm with dyspareunia in one. conclusions The use of porcine dermis in AVWP repair is safe with minimal graft related complications; however, anatomical success is lower than that reported with the use of synthetic grafts. .

Predictive factors for voiding dysfunction after transobturator slings / Fatores preditivos para disfunção miccional após cirurgia de sling transobturador

PURPOSE: To identify the predictive factors for voiding dysfunction after transobturator slings. METHODS: We retrospectively reviewed the records of all patients who underwent a transobturator sling between March 2003 and December 2008. A total of 514 women had available data with at least a six-week follow-up. Patients' demographics, preoperative symptoms, urodynamic testing including multichannel voiding studies and surgical variables were tabulated. Voiding dysfunction was defined by a catheterized or ultrasonographic postvoid residual greater than 100 cc (≥six weeks after the procedure) associated with any complaints of abnormal voiding. Univariate logistic regression analysis was performed with respect to postoperative voiding dysfunction. RESULTS: The patient population had a mean age of 58.5±12.9 years. Thirty-three out of 514 patients (6.4%) had postoperative voiding dysfunction according to our definition, and 4 (0.78%) required sling transection. No differences were observed between normal and dysfunctional voiders in age, associated prolapse surgery, preoperative postvoid residual, preoperative urinary flow rate, prior pelvic surgery, and menopausal status. Valsalva efforts during the preoperative pressure flow study was the only predictive factor for postoperative voiding dysfunction, 72.4% dysfunctional versus 27.6% normal (p<0.001). CONCLUSION: Preoperative Valsalva maneuver during the micturition could identify those at risk for voiding dysfunction after transobturator sling, and it should be noted during preoperative counseling.

OBJETIVO: Identificar fatores preditivos para disfunção miccional após a cirurgia de sling transobturador. MÉTODOS: Foram revisados, retrospectivamente, os protocolos de todas as pacientes que foram submetidas à cirurgia de sling transobturador. Entre março de 2003 e dezembro de 2008, 514 mulheres apresentavam dados disponíveis com ao menos seis semanas de seguimento. Foram avaliados os dados demográficos, os sintomas pré-operatórios, o estudo urodinâmico e as variáveis cirúrgicas. A disfunção miccional foi definida como o resíduo pós-miccional (verificado por sondagem vesical ou ecografia) superior a 100 mL (≥seis semanas após procedimento cirúrgico), que foi associado à queixa de micção anormal. Realizou-se análise por regressão logística univariada com relação à disfunção miccional pós-operatória. RESULTADOS: A população de pacientes tinha uma média de idade de 58,5±12,9 anos. Trinta e três das 514 (6,4%) participantes apresentavam disfunção miccional pós-operatória de acordo com a nossa definição e 4 (0,78%) necessitaram secção do sling. Não houve diferenças com relação à cirurgia para prolapso associada, ao resíduo pós-miccional pré-operatório, à urofluxometria pré-operatória, à cirurgia pélvica prévia e ao estado menopausal entre aquelas que apresentaram disfunção miccional quando comparadas às outras. A identificação da manobra de Valsalva durante o estudo miccional pré-operatório foi o único fator preditivo para disfunção miccional pós-operatória, 72,4% no grupo com disfunção versus 27,6% nas normais (p<0,001). CONCLUSÃO: A manobra de Valsalva pré-operatória durante a micção pôde identificar as mulheres que apresentavam maior risco para disfunção miccional após cirurgia de sling transobturador, e deve ser levada em consideração no aconselhamento pré-operatório das mesmas.
