“…Tray, as we describe it, could be a time of maximal cicatrization or a secondary amelioration that continues, but was not found in this study. Points of departure on the curve are very near to immediate traction on cadavers of tapes the same width [8]. An increase in resistance to traction is linked to cicatrization, mainly collagen fibers invading pores of the mesh.…”

Tissue resistance of the tension-free procedure: What about healing?

The aim of our work was to objectify and quantify the mechanical benefits of healing with regards to tearing meshes off of tissues and maximal resistance after cicatrization. In vivo, we tested the mechanical gain in resistance by healing after implantation of a Prolene mesh. We measured the value of forces when traction was exerted until mobilization at different stages of cicatrization. Resistance increased progressively at the beginning of tissue inclusion. A maximal plateau was reached around the 25th day. It is important to understand the role of sustaining and reinforcement we hope tissue integration of the mesh will play. We can thus adapt procedures to have the best kinetics and maximal resistance of montages. Study of the kinetics and maximal plateau allows us to make the best clinical recommendations.

“…Further research in this area with the use of mathematical modeling may also help to better understand the mechanical behaviour of implants. It has been experimentally determined that the force required to dislodge one tranobturator arm 76 is about 5–6 N. Higher forces are likely to be required in vivo, given that forces are exerted at an angle to the mesh arms/anchors and that anterior anchored meshes are suspended by four arms. Since mesh arm dislodgment is strongly associated with hiatal area on Valsalva, this parameter is likely to be a crucial input variable for pelvic floor modelling.…”

The popularity of imaging in pelvic floor medicine continues to increase. Among the various modalities, ultrasound is superior as it is cheap, safe, easily accesible and simple, resulting in high patient compliance. It is the only technique that allows imaging of modern wide‐weave polypropylene sling or mesh implants, and imaging of such implants is commonly required due to the popularity of surgical techniques that involve the placement of slings and meshes. This review article will discuss the role of translabial ultrasound in the evaluation of synthetic implants used in the treatment of urinary incontinence and pelvic organ prolapse.

Le prolapsus urogénital affecte l'équilibre anatomique et mécanique de la statique pelvienne. Les hypothèses physiopathologiques sont nombreuses. Étant donné la complexité des systèmes biomécaniques en jeu, il est nécessaire de mettre au point et de développer des modèles informatiques. Ils constituent une simplification des systèmes étudiés et permettent de simuler et de prévoir leurs comportements face à des modifications de l'environnement. Le modèle simule des situations physiologiques, pathologiques ou thérapeutiques. Notre objectif est d'aboutir à une évaluation de la maladie et à une personnalisation thérapeutique des troubles de la statique pelvienne. Nous avons défini un premier cahier des charges représenté par les prérequis au développement du modèle pelvien. Cette méthodologie repose sur trois axes principaux et incontournables: l'élaboration d'un modèle géométrique, la caractérisation mécanique des tissus organiques et la réalisation de mesures de contraintes mécaniques in vivo. L'étude préliminaire de faisabilité du modèle de cavité pelvienne a permis initialement de poser les bases du modèle, les moyens à mettre en œuvre tant sur les plans humains que matériels. Le modèle mécanique de cavité pelvienne est en constante évolution. Son développement répond à une politique d'évaluation de nos pratiques. Le modèle sera un outil objectif supplémentaire d'évaluation de la maladie et des techniques de correction. Il permettra le développement d'innovations efficaces et sûres pour diagnostiquer, prendre en charge et traiter le prolapsus. Il est à l'heure actuelle non exploitable à ce titre, mais en devenir. Il reste à envisager les solutions pour lever les verrous technologiques à son développement
