Volume matters: CT-based renal cortex volume measurement in the evaluation of living kidney donors

Anatomical Evaluation of Renal Arteries and Veins in Kidney Donors by CT Angiography

Abstract Background: Renal transplantation (RT) is the transplantation of a kidney into a patient with end-stage renal disease and has become the treatment of choice for most patients with end-stage renal disease. The knowledge of renal vascular variations is of a great importance for the surgeons who approach the kidneys from the retroperitoneal o...

Quantification of Single-Kidney Function and Volume in Living Kidney Donors Using Dynamic Contrast-Enhanced MRI.

OBJECTIVE The objective of our study was to investigate whether dynamic contrast-enhanced MRI (DCE-MRI) can detect differences and potential adaption in single-kidney parenchymal volume, blood flow, glomerular filtration rate (GFR), and filtration fraction in the remaining kidney of healthy donors compared with nondonors. Further, we evaluated the agreement in donor GFRs measured using DCE-MRI ...

An automatic method for renal cortex segmentation on CT images: evaluation on kidney donors.

RATIONALE AND OBJECTIVES The aims of this study were to develop and validate an automated method to segment the renal cortex on contrast-enhanced abdominal computed tomographic images from kidney donors and to track cortex volume change after donation. MATERIALS AND METHODS A three-dimensional fully automated renal cortex segmentation method was developed and validated on 37 arterial phase co...

Evaluation of Potential Living Kidney Donors

Evaluation of high-risk living kidney donors.

Careful evaluation of potential living kidney donors is crucial to assure the well being of the donors, especially because they do not gain any direct medical benefit from donation. This process also helps assess the quality and safety of the organs donated to the recipients. While all programs share these goals, donor selection criteria vary significantly among U.S. transplant centers. In part...
