Influence of Age on the Characterization of Elasticity of Prolapsed Vaginal Tissue on a Postmenopausal Women Group


Introduction and Objective: The objective of the current study is to evaluate the influence of age on the Elasticity of prolapsed vaginal tissue. Despite the recent efforts of several researchers [1,2], the mechanical properties of vaginal tissue are not fully understood. This information is important, for example, as an aid to evaluate the adequacy of urogynecologic implant materials [3], or it can be a contribution to the improvement of numerical simulations related with the pelvic cavity on women with pathologies like pelvic organ prolapse or urinary incontinence.

Methods: For the current study 28 post-menopausal patients were considered. Patient‚s age ranged from 49 to 84 years old. All patients were assisted on São João Hospital, and live on the North of Portugal. The tissue samples were collected between April of 2006 and October of 2007. Sample removal was performed during prolapse correction surgeries, according to a procedure approved by the Ethics Committee of S. João Hospital. Uniaxial tension tests were performed. The maximum time until testing was 6 hours and most of the specimens were tested no more than 4 hours after surgery. It was measured an elasticity parameter E describing the linear elastic portion of the stress/stretch curves [3]. The software package MATLAB® version 7 for windows was the platform used for statistics, data interpolation and graphical presentation of the results. The R-square value (complete miss? 0 = R-square = 1? complete match) was as a statistical measurement for the accuracy of the curve fittings presented.

Results: The experimental (average ± SD) value obtained for the elasticity parameter E was E = 12.34 ± 4.71 MPa. The results of the current study are a close match to those reported in [1], considering that they were achieved with a different experimental protocol [2,3]. A linear approximation of E (E˘-0.017*age+13; R-square = 0.001) shows a slight decreasing tendency of this property with age. However, a very small R-square coefficient indicates that the fitting does not describe the experimental results with accuracy.

Conclusion: It is known that biomechanical properties of living tissues are influenced by a multitude of patient dependent factors [4]. For the particular case of vaginal tissue, there have been recent works [1,2] debating the influence of patient dependent characteristics (such as age or parity) on the biomechanical properties. The present study, in agreement with the consulted literature, indicates that patient age does not influence the biomechanical properties of prolapsed vaginal tissue in any special way [1], but nevertheless does have some influence.

Preoperative Urodynamic Testing Does Not Predict Postoperative Voiding Dysfunction Among Women Undergoing Surgery for SUI: Results from a Prospective Randomized Trial Comparing Burch Versus Pubovaginal Sling



Voiding dysfunction (VD) may occur in 2-20% of patients following surgery for stress urinary incontinence (SUI). Urodynamic studies (UDS) have been proposed as a means of identifying patients at risk for VD.

Changes in Physical Activity after Sacrocolpopexy for Advanced Pelvic Organ Prolapse


Introduction and Objectives: The aim of this study is to report the functional results, patient satisfaction, and morbidity of the Transobturator tape procedure (TOT) in the treatment of stress urinary incontinence (SUI). 204 patients with mean age of 58.8 years (range 31-72) who have completed a minimal follow-up of 12 months were enrolled in this study. 157 patients (77%) had history of stress incontinence and 47 patients (23%) had history of mixed incontinence. 153 patients had concomitant gynecological pathology (pelvic organ prolapse).

Urodynamic Changes Associated with Successful Stress Urinary Incontinence Surgery: A Little Tension is a Good Thing?


Introduction and Objectives

The aim of this study is to identify urodynamic changes that correlate with overall success after stress urinary incontinence surgery.

Urodynamic Changes 24 Months After Burch Colposuspension and Autologous Fascia Pubovaginal Sling



The purpose of this analysis was to determine the reference urodynamic values for preoperative urodynamic studies in women undergoing surgery for pure or predominant stress urinary incontinence (SUI) by describing values in a large cohort of women.

The Monarch Transobturator Tape in our Centre: Initial Results Promising, but Beware Worsening of Bladder Overactivity

Introduction and Objectives: Transobturator tapes (TOTs) are a well established procedure performed in female stress incontinence. The relatively low rate of complications and reduced hospital stay make it an attractive alternative to traditional incontinence surgery. The purpose of this study was to demonstrate our experience of TOTs since introduction in our hospital in 2005.

Objectives: The aims of this prospective study were to determine, one year after sacrocolpopexy for pelvic organ prolapse 1) the changes from baseline in the proportion of women who participated in recreational exercise and strenuous physical activities, 2) the changes in interference from either prolapse or its treatment with ability to do housework, work outside the home, or participate in exercise or recreation, and 3) factors that contribute to current perceived interference with physical activity.

Qualiveen Italian Validation: A Long and Short Form Quality of Life Questionnaire in Patients with Spinal Cord Injury and Urinary Disorders


Introduction: There exists a need to assess the impact of urinary disorders (UD) on spinal cord injury (SCI) patients’ health-related quality of life. Qualiveen is a specific health-related quality of life (HRQL) questionnaire for UD in neurologic conditions such as multiple sclerosis (MS) and SCI patients. Its long version (30 items) as well as its short form (SF-Qualiveen with 8 items) have proved reliable, valid, and responsive in French-speaking and English-speaking MS and SCI patients with UD.
