Renal Imaging: Core Curriculum 2019.

Am J Kidney Dis 2019 Feb 15. Epub 2019 Feb 15.

Department of Radiology, University of Pennsylvania, Perelman School of Medicine, Philadelphia, PA. Electronic address:

Renal imaging has become a fundamental part of clinical care for patients with kidney disease. Imaging strategies for the kidney have been evolving during the past hundred years and have been even more rapidly changing during the past couple of decades due to the development of modern computed tomographic techniques, magnetic resonance imaging, and more sophisticated ultrasonographic techniques, such as contrast-enhanced ultrasonography. Applying the correct radiologic study for the clinical situation maximizes the diagnostic accuracy of the imaging, and a judicious choice between techniques helps limit radiation dose and potential adverse events.

Evaluation of a protocol for coronary artery disease investigation in asymptomatic elderly hemodialysis patients.

Int J Nephrol Renovasc Dis 2018 14;11:303-311. Epub 2018 Nov 14.

Heart Institute (InCor) and Renal Transplant Unit, Division of Urology, Hospital das Clínicas, University of São Paulo Medical School, São Paulo, SP, Brazil,

Background: Coronary artery disease (CAD) is prevalent in older patients on dialysis, but the prognostic relevance of coronary assessment in asymptomatic subjects remains undefined. We tested the usefulness of a protocol, based on clinical, invasive, and noninvasive coronary assessment, by answering these questions: Could selecting asymptomatic patients for coronary invasive assessment identify those at higher risk of events? Is CAD associated with a worse prognosis?

Methods: A retrospective study including 276 asymptomatic patients at least 65 years old on the waiting list, prospectively evaluated for CAD and followed up until death or renal transplantation, were classified into two groups: 1) low-risk patients who did not undergo coronary angiography (n=63) and 2) patients who did undergo angiography (n=213). The latter group was reclassified into patients with significant CAD or normal angiograms/nonsignificant CAD. Read More
