| Abstract: | This review describes our experience with renal duplex sonography (RDS) in the elderly as a screening study for renovascular disease and as an intraoperative completion study to define technical error after operative renal artery repair. Methods of patient preparation, technical aspects of renal duplex interrogation and the comparison of RDS results with angiography in the elderly are presented in detail. In the hands of an experienced sonologist, RDS examination performed according to these methods and techniques correlates highly with angiography. We believe renal duplex sonography is the preferred screening test for main renal artery stenosis and occlusion in the elderly population. |
