An artificial urinary diversion system is disclosed, which consists of a first area with at least one outlet, a second area, and a third area with at least one inlet for accommodating a urinary bladder. The second area is arranged between the first area and the third area, and that the cross-sectional surfaces of the first and/or second areas which are perpendicular to the axial alignment of the urinary diversion system are smaller than the cross-sectional surface of the third area, thereby providing a shape that can be adapted to almost any patient. These artificial urinary diversion systems provide adaptable systems that can be produced without previous direct or indirect determination of the potentially available volume for the system, and that facilitate an as effective as possible determination and utilization during the surgical phase of the volume available in the patient.
