The goal of any form of urinary diversion should be the control of urinary bladder disease and the preservation of a patient's quality of life (QoL). Safeguarding a patient's QoL is related both to the surgical urinary diversion form that is psychologically and socially acceptable and to the preservation of renal function.1 In fact, there are several reasons for deterioration of renal function that are generally diversion-related.2 In this sense, the incorporation of an antireflux system with urinary diversion or bladder replacement should protect the upper tract from regurgitation of the infected contents of the reservoir.
