A new business concept that offers products and services in a different way of traditional product-sales businesses is getting more attention especially in manufacturing industries. This paper investigates how this new business by means of integration of products and services is achieved in Germany and Italy. In addition, it analyzes the differences according to the company sizes. The results include that this type of business is in many cases motivated by their focus on customers and often consists of physical products and their maintenance. The Italian companies, as opposed to the German ones, often design their physical products specifically for this type of offers. From the analysis based on the size difference, small companies are found to achieve specific design for this type of offers while owning physical products. There do not seem to be any established methods or tools developed to support the development of such offers and within such methods/tools there would be room for more adaptation in form of physical product design.

Dear editor,In recent years,endoscopic subureteral transurethral injection(STING)has become the first-line therapy for children with vesicoureteral reflux(VUR)owing its diffusion in clinical practice to a high success rate and minimum complications[1].Macroplastique(Uroplasty,Inc.,Minnetonka,MN,USA)is an efficient and safe bulking agent commonly used in VUR,being non-migratory,non-antigenic,and ***,its stability over time,with a virtual no-reabsorption phenomenon,has allowed its application in wider medical fields[2].
