Since the late 1980s, different reservoirs and bladder substitution techniques have been added to the urological surgical armamentarium. The necessary use of an intestinal segment--generally detubularized--make these surgical procedures complicated and time-consuming. Furthermore, problems are encountered postoperatively due to the important morbidity arising from these procedures. The present article describes our experience with mechanical sutures and resorbable material. Although the results have not been analyzed, our initial experience at the Miguel Servet Hospital has shown that these devices significantly facilitate the operative procedure, thereby reducing the incidence of urinary and intestinal fistulas. Although there is an evident risk of calculi formation, complicated solutions are not required and the biological tolerance to the metal sutures is excellent.
