Kissing balloon technique for angioplasty of renal artery bifurcation stenoses.

This study evaluates long-term results after using the kissing balloon technique in percutaneous transluminal angioplasty of bifurcation stenoses of the renal artery. Eight patients with proven renal artery stenosis and deterioration of renal function were treated, including one kidney transplant recipient. Follow-up ranged between 3 and 131 months. All interventions were technically successful. All patients improved in one or more of the following: serum creatinine levels and creatinine clearance, blood pressure, and need for antihypertensive medication. The kissing balloon technique is a reliable and safe method for treating bifurcation stenoses of the renal artery, rendering stable long-term results.
