ABSTRACT
Since the very first urinary diversion performed by Simon in 1852,1 an issue that has been a matter of significant debate is the need for reflux prevention. In this chapter, we shall discuss the arguments for and against reflux prevention in urinary diversion by reviewing the evidence regarding the possible adverse effects of reflux as well as the results of experimental and clinical studies that have looked at the issue of the need for reflux prevention in urinary diversion. We shall briefly review the different types of ureterointestinal anastomoses with respect to reflux prevention and the complications thereof, and the clinical results of different urinary diversions that have and have not incorporated reflux prevention.
