Abstract

Renovascular disease in a solitary kidney is a difficult and challenging problem. In six patients, with a mean age of 62 years, revascularisation was undertaken. In four of them, one to three attempts at PTA were made before the operation but all were unsuccessful. The preoperative mean serum creative (Cr) was 3.52mg% (range 2.5-5.5). The stenoses were caused by atherosclerosis in five cases and fibromuscular dysplasia (FMD) in one. Two methods of revascularisation were used: aortorenal bypass with saphenous vein (three patients) or PTFE (two patients), and transaortic renal endarterectomy with a venous patch (one patient). One patient with an aortic aneurysm underwent simultaneous aortic repair with a PTFE graft. There was no mortality or major complications in our series and no patient suffered acute tubular necrosis (ATN) after surgery. The mean follow-up period was 51 months (15-84 months). Postoperative Cr and blood pressure improved in all patients. Four patients no longer required any medication and the other two only needed reduced doses of antihypertensive drugs. Based on our experience of patients with poor single kidney function, we do not recommend PTA in this specific group of patients and suggest an aggressive surgical approach, which can effectively improve solitary kidney function, thus eliminating further haemodialysis.
