Revision Using Distal Inflow is a surgical treatment for Dialysis-associated Steal Syndrome. RUDI was first proposed by David J. Minion and colleagues in 2005. In the procedure, the fistula is ligated at a location slightly proximal to the anastomosis. A bypass to the venous outflow is then created from a distal arterial source.

In a review of a three studies on the efficacy of the technique, RUDI was shown to provide good patency and 100% symptom resolution.
