Does uremic enterocolitis exist? A morphological and functional investigation of rat intestine in chronic renal insufficiency.
In rats a severe but compensated chronic renal insufficiency was induced by stepwise 9/10 nephrectomy. Despite this severe chronic renal insufficiency we observed no relevant pathological changes in the intestinal mucosa. In particular, we found no evidence of mucosal erosions, ulceration or pseudomembranous colitis, findings which are traditionally thought to be characteristic of the uremic state. This was also true of those animals dying prematurely from uremia. Thus serious doubts arise about the existence of "uremic enterocolitis", doubts which also proved justified after a critical review of the literature on human pathology.
