摘要：

Purpose: To retrospectively evaluate the results of renal artery stenting in patients with renovascular disease and a solitary functioning kidney. Methods: Palmaz stents were placed in 16 patients with a solitary functioning kidney, renal artery stenosis, hypertension and renal failure. Stenoses were evaluated with color Doppler ultrasound, MR angiography and digital subtraction angiography (DSA). Indications for stenting were: recoil after percutaneous transluminal renal angioplasty (PTRA) (63%), arterial dissection after PTRA (13%) and primary stenting (25%). Immediate results were evaluated by DSA. On follow-up (6-36 months), patients underwent periodical evaluation of clinical conditions (blood pressure and serum creatinine level) and stent patency, by means of color Doppler ultrasound. Results: Stent placement was successful in all patients (100%). Cumulative primary patency rate was: 100% at 1 day, 93.75% at 6 months, 81.25% at 12 months and 75% at 24 months. A significant reduction in diastolic blood pressure occurred (mean +/- SD 104 +/- 6 vs 92 +/- 3; p < 0.05); renal function improved or stabilized in over 80% of patients. However. there was no significant difference in the creatinine values before and after treatment (mean +/- SD 200 +/- 142 mumol/l vs 197 +/- 182 mumol/l; p > 0.05). Conclusion: Renal artery stenting, both after MA and as primary stenting, represents a safe procedure, able to preserve renal function in patients with a solitary functioning kidney.
