Key result
Angiographic evaluation enabled correct differential diagnosis of chronic glomerulonephritis, chronic pyelonephritis, and advanced arteriolonephrosclerosis in 88% of cases.
Why the study?
Can angiographic features accurately differentiate between chronic glomerulonephritis, chronic pyelonephritis, and advanced arteriolonephrosclerosis?
Observational
Can angiographic features accurately differentiate between chronic glomerulonephritis, chronic pyelonephritis, and advanced arteriolonephrosclerosis?
Angiography can differentiate between major causes of chronic renal parenchymal disease with 88% accuracy using specific morphological signs.

Should not yet change diagnostic practice for chronic renal disease; leaves open prospective validation of angiographic accuracy.
The angiographic features of chronic glomerulonephritis, chronic pyelonephritis, and advanced arteriolonephrosclerosis were evaluated and compared. Three features of discriminatory value were found, enabling correct differential diagnosis in 88% of cases: (a) the “lucent cortex sign,” seen most commonly in chronic glomerulonephritis as the result of markedly diminished peripheral cortical perfusion; (b) small lucencies of nephrosclerosis, due to multiple tiny infarcts; and (c) fine dense granularity of chronic pyelonephritis, due to heterogeneous preservation of reduced numbers of glomeruli.
