[Percutaneous transluminal renal angioplasty of the solitary kidney].
We report on our experience with percutaneous transluminal angioplasty (PTA) of the renal artery in solitary kidney patients. PTA was performed on 31 subjects (mean age: 52 years): 7 had a solitary kidney because of nephrectomy and 24 had a solitary functioning kidney. Patients were selected with clinical and laboratory examinations first and then with angiography. PTA was employed to treat renal artery stenoses 60%-95% of the whole arterial lumen. The procedure has been considered technically successful in 29 cases, with 77%-33% reduction of the mean amount of stenosis. As to the clinical evaluation of the results, blood pressure and creatinine values variations were considered. Of the 25 patients on follow-up, 13 appeared to be treated (52%), 8 improved (32%) and 4 unchanged (18%). On the whole, we observed 5 complications (2 hematomas at the approach site, 1 intimal dissection and 2 segmental infarcts), with a 23.4% rate comparable with PTA complications in non-solitary kidney patients. The good revascularization, the reduction in blood pressure values, the very small percentage of complications point to PTA of the renal artery as the procedure of choice in solitary kidney patients.
