Abstract (EN): BACKGROUND: Besides material biocompatibility, it is possible to infer that both vaginal and urethral erosion rates associated with sub-urethral synthetic slings may be related with the mechanical properties of the meshes and also with other characteristics. OBJECTIVE: With the aim of understanding what distinguishes the different polypropylene meshes, used for the treatment of the stress urinary incontinence (SUI), their fundamental properties were investigated. DESIGN AND SETTING: Five different mesh types were tested (Aris™, Auto Suture™, Avaulta™, TVTO™ and Uretex™). The chemical tests performed were differential scanning calorimetry (DSC) and infrared (FTIR). Furthermore, geometry (electron microscope), linear density and relative density (pyknometer) of the meshes were investigated. RESULTS AND LIMITATIONS: The material of the meshes is the isotactic polypropylene homopolymer. Aris™ mesh presented the smallest fiber diameter, linear density and level of crystallinity of all the meshes used for the treatment of the SUI. The mechanical behaviours of the Auto Suture™ and Avaulta™ meshes are still unknown. CONCLUSIONS: Concerning the polypropylene meshes used for the treatment of the SUI, this study shows that there is a direct relation between fiber diameter, linear density and level of crystallinity with flexural stiffness.
