Abstract

This study evaluates the effect of renal artery stenting on renal function in 72 consecutive patients. Baseline renal function was considered "abnormal" if creatinine was ≥ 1.5 mg/dl. "Improvement" was defined as decrease in creatinine by ≥ 20%, "unchanged" if variation was ≤ 20%, and "worse" if creatinine increased by ≥ 20%. Two patients (2/72 = 2.8%) had in-hospital death. Follow-up creatinine was available in 61/70 (87%) patients at 21 ± 11 months (9 patients lost to follow-up). Forty-four (44/61, 72%) patients had normal baseline creatinine that remained "unchanged" in 42/44 (95%, p = ns). Seventeen (17/61, 28%) patients had "abnormal" baseline creatinine. The renal function "improved" in 3/17 (18%), from 2.7 ± 1 to 1.6 ± 0.6 mg/dl (p = 0.06). Creatinine remained "unchanged" in 9/17 (53%), and was "worse" in 5/17 (29%, 2.0 ± 0.51 to 3.3 ± 0.34 mg/dl, p = 0.005). In conclusion, the renal function remained stable in 89% of patients and worsened in 11% of patients at 21 months (follow-up available in 87% of the eligible patients) following renal artery stenting. In patients with baseline renal insufficiency (serum creatinine > 1.5 mg/dl), the renal function remained stable in 71% of patients.
