A guiding catheter was used in seven patients who underwent balloon dilation of nine renal arteries. The advantages of using a guiding catheter for renal angioplasty are analogous to the benefits obtained with a coronary angioplasty guiding catheter used in coronary angioplasty. The guiding catheter provides back-up support to cross lesions and allows selective contrast visualization of the lesion before, during, and after dilation. It is also possible, when using a guiding catheter, to measure pressure gradients across lesions without having to recross the lesion which may help to ensure that adequate dilation of the stenosis has been accomplished.
七名接受九条肾动脉球囊扩张术的患者使用了引导导管。在肾血管成形术中使用引导导管的优点类似于在冠状动脉成形术中使用冠状动脉成形术引导导管所获得的益处。引导导管为通过病变提供了后备支持，并允许在扩张前、扩张期间和扩张后对病变进行选择性造影显影。在使用引导导管时，还可以测量病变两端的压力梯度，而无需再次通过病变，这可能有助于确保狭窄已得到充分扩张。
