2. Fig 1
Cases per year per 100,000 adults. There has been a 46% increase in discharges with a diagnosis code for renovascular hypertension and renal artery atherosclerosis over the study period (P = .0002).

3. Fig 2
A 73% and 56% decline in combined aortic and renal, as well as isolated renal revascularizations (P = .033 and P < .001) occurred over the 14-year study period. Angioplasty and stenting increased 173% (P < .001).

There was a significant regional variation in rates of percutaneous intervention for revascularization (P < .001).

In hospital mortality versus time. By χ2 analysis, there were no significant variations in mortality over time for any treatment class.

6. Fig 5
All treatment classes exhibited trends towards decreasing length of stay (P < .001 for all groups). At all time points, combined aortic and renal revascularization had the longest average length of stay, followed by isolated renal revascularization, and then angioplasty and stenting (P < .001).

7. Fig 6
There were significant regional variations in mean length of stay for patients undergoing aortic and renal reconstruction (P = .009), isolated renal reconstruction (P < .001), and angioplasty and stenting (P = .004).

8. Fig 7
There were no significant trends in total hospital charges for either combined aortic and renal or isolated renal surgical repairs. Charges for angioplasty and stenting increased significantly (P < .001), approaching charges for isolated surgical renal revascularization. All costs were corrected for 4% annual inflation.

There were significant regional variations in total hospital charges for patients undergoing aortic and renal reconstruction (P = .001), isolated renal reconstruction (P = .017), and angioplasty and stenting (P < .001).

10. Fig 9
All treatment classes exhibited a significant trend towards increased risk of unfavorable discharge (P = .002 for aortic and renal reconstruction, P = .004 for isolated renal revascularization, and P < .001 for angioplasty and stenting).

11. Fig 10
There were significant regional variations in the rate of unfavorable discharge for patients undergoing aortic and renal reconstruction (P = .03) and isolated renal reconstruction (P = .007).
