Abstract
SUMMARY: Main renal and pelvic artery branches of pigs were found to develop ruptures and deficiencies of the internal elastic lamina during experimental hydronephrosis. Arteries supplying the affected kidney were predominantly affected but in some instances the elastic laminae changes were present in the arteries supplying the contralateral kidneys. One obstructed kidney, known to be of normal size before ureteric ligation, was found to have renal artery stenosis due to fibromuscular medial hyperplasia. Evidence is presented that this may be causally related to ureteric obstruction.
