US measurements of AVF at 2-4 months in patients undergoing hemodialysis are highly predictive of fistula maturation and adequacy for dialysis.

Routine preoperative vascular mapping results in a marked increase in placement of AV fistulas, as well as an improvement in the adequacy of forearm fistulas for dialysis. This approach resulted in a substantial increase in the proportion of patients dialyzing with a fistula in our patient population. Fistulas have a higher primary failure rate than grafts, but have a lower subsequent failure rate and require fewer procedures to maintain their long-term patency.

Preoperative US mapping before hemodialysis access placement can result in a change in surgical management, with an increased number of AVFs placed and an improved likelihood of selecting the most functional vessels preoperatively. Further study is needed to determine longer term outcomes.

Early steroid-withdrawal in renal transplant recipients with a sirolimus and CellCept-based calcineurin inhibitor-minimimization protocol can effectively reduce many of the steroid-related side effects, decrease risk factors for cardiovascular disease, and is associated with improved recipient survival without compromising graft function.

Preemptive ganciclovir therapy provides a cost-effective approach toward significantly improving the outcome of renal transplantation in CMV-seropositive patients treated with ALA.

Preservation with PP improves early graft function and lessens the adverse effect of increased warm ischemia in cadaveric renal transplantation. This method is likely associated with less preservation injury and/or increases the threshold for injury from other sources and is superior to CS.

Background: Early immunologic and non‐immunologic injury of renal allografts adversely affects long‐term graft survival. Some degree of preservation injury is inevitable in cadaveric renal transplantation, and, with the reduction in early acute rejection, this non‐immunologic injury has assumed a greater relative importance. Optimal graft preservation will maximize the chances of early graft function and long‐term graft survival, but the best method of preservation – pulsatile perfusion (PP) versus cold storage (CS) – is debated. 
Methods: Primary cadaveric kidney recipients from January 1990 through December 1995 were evaluated. The effects of implantation warm ischemic time (WIT) (≤20 min, 21–40 min, or >40 min) and total ischemic time (TIT) (< or ≥20 h) on death‐censored graft survival were compared between kidneys preserved by PP versus those preserved by CS. The effect of preservation method on delayed graft function (DGF) was also examined. 
Results: There were 568 PP kidneys and 268 CS kidneys. Overall death‐censored graft survival was not significantly different between groups, despite worse donor and recipient characteristics in the PP group. CS kidneys with an implantation WIT >40 min had worse graft survival than those with <40 min (p=0.0004). Survival of PP kidneys and those transplanted into 2 DR‐matched recipients was not affected by longer implantation WIT. Longer TIT did not impact survival. DGF was more likely after CS preservation (20.2% versus 8.8%, p=0.001). 
Conclusions: Preservation with PP improves early graft function and lessens the adverse effect of increased warm ischemia in cadaveric renal transplantation. This method is likely associated with less preservation injury and/or increases the threshold for injury from other sources and is superior to CS.
