Renal parenchymal preservation after percutaneous renal angioplasty and stenting

Parenchymal loss: Kaplan-Meier analysis of parenchymal loss of each kidney treated for the entire cohort of patients (A) and for patients presenting with hypertension, elevated creatinine or Hypertension with elevated creatinine (B) patients. The number of kidneys at risk at each time interval is shown below each figure. Values are mean ± standard error of the mean. Standard errors exceeding 10% are not shown.

(A) Patency: Kaplan-Meier analysis of assisted primary patency of the renal arteries with and without parenchymal loss. (B) Restenosis: Kaplan-Meier analysis of freedom from restenosis of the patients with and without parenchymal loss. The number at risk at each time interval is shown below each figure. Values are mean ± standard error of the mean. Standard errors exceeding 10% are not shown.

(A) Survival: Kaplan-Meier analysis of survival of the patients with and without parenchymal loss. (B) Renal related morbidity: Kaplan-Meier analysis of freedom from renal related morbidity (persistent increase in creatinine >20% of baseline, progression to hemodialysis, death from renal-related causes) of the patients with and without parenchymal loss. The number at risk at each time interval is shown below each figure. Values are mean ± standard error of the mean. Standard errors exceeding 10% are not shown.
