The aim of the study was to present a case of virtual patient with urinary incontinence (UI), the treatment especially based on the new muscle-derived stem cell (MDSC) procedure. With the use of e-learning systems, the UI patient’s classical follow-up as well as MDSC sphincter injection therapy are shown. The “Virtual Patient” case allowed us to demonstrate the main results and the creation of a robotic system from the MDSC study. In this way, the authors will disseminate the new procedure developed in Collegium Medicum JU in UI patients. The “Virtual Patient” case may help students get involved in this new procedure along the main program.

Besides material biocompatibility, it is possible to infer that both vaginal and urethral erosion rates associated with sub-urethral synthetic slings may be related to the mechanical properties of the meshes and also to their other properties. With the aim of understanding what distinguishes the different polypropylene meshes, used for the treatment of the stress urinary incontinence (SUI), their structural and thermal properties were investigated. Five different mesh types were tested (Artis™, Auto Suture™, Avaulta™, TVTO™ and Uretex™). Differential scanning calorimetry (DSC) and infrared spectroscopy (FTIR) tests were performed. Furthermore, geometry (electron microscope), linear density and relative density (pyknometer) of the meshes were investigated. The meshes are made of the isotactic polypropylene homopolymer. Artis™ mesh presented the smallest fibre diameter, linear density and the level of crystallinity among all the meshes used for the treatment of the SUI. This study shows that there is a direct relationship between the fibre diameter, linear density, level of crystallinity and flexural stiffness of the polypropylene meshes used for the treatment of the SUI.
