Intrarenal Hydronephrosis, 16466

16466              Intrarenal Hydronephrosis


The patient was a man of 75 who died from a myocardial infarction.

The specimen consists of a bisected kidney, ureter, bladder and prostate. The prostate shows adenomatous hyperplasia. The small thick-walled trabeculated bladder has two large lateral diverticula. The ureter is normal in size. There is gross internal hydronephrosis which has reduced the functioning cortical tissue to a thin rind. This was presumably due to kinking of the ureter over a downwardly directed branch of the renal artery. A simple cortical cyst can also be seen. A branch of the renal artery has been cut across as it enters the region of the pelvis and it can be seen to be almost totally obliterated by atherosclerosis.
