Cortical thickness: An early morphological marker of atherosclerotic renal disease

Abstract

These results suggest that cortical parameters are more sensitive for early diagnosis of ARD than kidney size. Cortical atrophy should be a useful marker for guidance for revascularization.

Genetic and environmental variance of renal parenchymal thickness: a twin study

“…The left RPT was greater (eg, hypertrophied column of Bertin, persistence of fetal lobation, and dromedary hump, which are usually present at the middle third portion of the left kidney), and the greatest RPT was measured on that side. This interrenal difference has been previously shown (8,9,20).…”

“…A number of reports have shown that the amount of renal parenchyma decreases by about 10% per decade of advancing age for both kidneys, with the highest decrease rate in the sixth and the seventh decades independent of sex (8,9). Loss of renal parenchyma in the elderly is compensated for by an increase in peripelvic fat (9,21,22).…”

“…Ultrasound assessment of RPT can reliably differentiate between patients with acute or chronic renal failure (7). RCT and RPT are regarded as early and sensitive morphological markers for the early diagnosis of atherosclerotic kidney disease and correlate with the coronal diameter, renal volume, intraparenchymal resistance indices, glomerular filtration rate, and proteinuria (8).…”

Different strategies for MRI measurements of renal cortical volume

“…It is generally accepted that renal cortical volume (Vc) diminishes over time in patients with chronically injured kidneys (3). Measurements of Vc may therefore be a good predictor for the progression of chronic kidney diseases, introduced as a prognostic parameter prior to renal transplantation, and may supplement measurements and investigations such as glomerular filtration rate, renographies, and biopsies.…”

“…Semiautomatic segmentation of renal cortex revealed volumetric estimations of the renal cortex ( 3 . The intraindividual and interindividual reproducibilities were Ͻ3% and Ͻ4%, respectively.…”
