Interventional nephrology is in the midst of an exponential growth phase, with data from the U.S. Renal Data System suggesting that at least 25 percent of total vascular access procedure costs are billed by nephrologists (1). Indeed, it is likely that the growth of interventional nephrology as a distinct discipline within nephrology has played an important role in the success of process-of-care initiatives, such as Fistula First, which has raised the arteriovenous fistula (AVF) prevalence rate from 34 percent in December 2003 at the start of this initiative to 59.5 percent as of August 2011 (2).
