Vagina, abdominal skin, and aponeurosis: do they have similar biomechanical properties?

Abstract

skin and aponeurosis are not suited to predict vaginal tissue biomechanics. We should be cautious when transferring experiences from abdominal wall surgery to vaginal reconstructive surgery.

Elongation of textile pelvic floor implants under load is related to complete loss of effective porosity, thereby favoring incorporation in scar plates

“…In general, stretchability is assumed to be in a range of 20-100%, depending on the recipient tissue. 13,15 However, any device with a high elasticity may lead to less resistance to withstand a prolapse. In particular, if intended to replace the ligaments, a high stretch ability seems to be dispensable, and thus may force the subsequent loss of effective porosity, as we could confirm in this study.…”

Caractérisation biomécanique des ligaments utérins. Implication en statique, en pelvienne

“…Ce protocole a été validé à chaque étape par des essais exhaustifs sur du tissu vaginal de brebis. Il a été utilisé dans plusieurs études portant sur le tissu vaginal sain et pathologique [10][11][12][13][14][15][16], la peau et l'aponévrose [13]. Il a fait ses preuves en termes de reproductibilité des mesures.…”

“…Les travaux sont difficilement exploitables en termes de biomécanique, compte tenu des différen-tes méthodes de mesures des résistances. Un protocole de mesure et de conservation des tissus uniques a permis de comparer, dans le cadre de ce travail, les différents ligaments et tissus entre eux [13,16], ce qui va permettre d'obtenir une cartographie mécanique du pelvis féminin pour mieux comprendre la physiologie et la physiopathologie du prolapsus.…”

A nonlinear-elastic constitutive model for soft connective tissue based on a histologic description: Application to female pelvic soft tissue

“…Some papers defined an accurate experimental protocol [10][11][12]. This protocol was used in experimental campaigns on large numbers of samples of most soft tissues making up the female pelvic system [13][14][15][16]. A non-linear elastic behavior of the pelvic soft tissue was revealed for vaginal tissue by Rubod et al [16] and also by co-workers Gabriel et al [14] and Jean-Charles et al [15].…”

A non-linear elastic behavior of the pelvic soft tissue was revealed for vaginal tissue by Rubod et al [16] and also by co-workers Gabriel et al [14] and Jean-Charles et al [15]. To perform statistical studies on these soft tissues, Jean-Charles et al [15] proposed a phenomenological approach to model their behavior based on Mooney-Rivlin models [17].…”
